CHAPTER I. AN UXSEEN WORLD. Where the pool Stands mantled o'er with green, invisible, Among the floating verdure millions stray." IF Dr. Livingstone, in the course of his African explorations, were to light upon some such nation of mannikins as that dis- covered at Lilliput by Mr. Lemuel Gulliver of famous memory, the announcement of the fact could hardly occasion greater surprise and astonishment than was felt by the philosophers of the last century at the remarkable disclosures of the microscope, with respect to the countless multitudes of minute forms of organic life which, unseen by our feeble powers of vision, people the waters of the earth, and swarm around us on every side. The microscope has here revealed the existence of a new world of living beings, before unknown and unsuspected. It has shown that the water of our roadside ditches, and stagnant pools, of our lakes and streams, and of the sea itself, teems with various races of microscopic beings, many of which are so incon- ceivably minute, and abound in such amazing profusion, that thousands of them may often be detected in a drop of fluid taken up on the point of a pencil, while, within the narrow dimensions of a lady's thimble, we might easily collect together a number far exceeding that of the entire human population of the globe. It rarely happens that important discoveries are made at once in all their completeness, and the discovery of this unseen world of organic life forms no exception to the rule. It will be obvious, indeed, that, as many of these minute beings arc sufficiently largo D 2 EARLY DISCOVERIES. to be discernible by the unassisted eye, there would be at least some knowledge of their existence even in the earliest times. But it was not until the invention of the microscope had given to man the means of penetrating the mysterious depths of this diminutive creation that any definite knowledge was obtained, either of its vast extent or of the exceeding wonderfulness of the beings which composed it; while almost every improvement which has subsequently been made in the construction of the microscope has largely added to the wonders which the instru- ment has here revealed. The earliest microscopical observations of importance on these minute beings were made by Leeuwenhoek in the latter half of the seventeenth century ; but it was not until a much later period that this branch of study excited any great amount of interest, or was prosecuted with anything like persevering zeal. It was towards the middle of the last century that the great stimulus was given to researches of the kind, by the publication of the cele- brated memoir of H. Trembley, of Geneva, on the little Hydra, or fresh-water polyp of our ponds and ditches an animal whose extraordinary history read, and, indeed, still reads, more like an extravagant romance than a sober recital of actual facts. The publication of this work marks one of the most important epochs in the history of microscopical inquiry, and speedily turned the attention of observers in all parts of Europe to the abounding marvels of the waters. Nor is it at all remarkable that such should have been the result ; for this same Hydra is one of a race of animals of which, up to that time, naturalists had been almost wholly ignorant, while the details that were given of its habits and economy were such as completely upset most of the prevailing notions as to the dis- tinctive characteristics of animal life. For here was an animal whose young grew out from its sides like buds from the stem of a plant that might not only be cut into pieces without being killed, but would reproduce a perfect animal similar to itself from every fragment of its original substance that might be turned inside out, and yet suffer no detriment to its powers of digestion that might, in fact, be mutilated and operated upon in almost any conceivable fashion, not only without apparent injury, but without, or at all seriously, interfering with the functions of active life. It ia no wonder, therefore, that observers were everywhere INFUSORIAL ANIMALCULES. 3 eager to test the accuracy of these astounding assertions, or that a great impetus should thus have heen given to the general study of the minute forms of life with which the waters abound. But many years still passed before this branch of study was at all systematically pursued : and although towards the close of the last, and early in the present, century, it attracted to itself a con- siderable number of able and zealous investigators, it was not until almost our own day that it took its place as a recognized and important department of natural science. It was for many years customary to speak of these living atoms indiscriminately as the Infusoria, or as Infusorial Ani- malcules, from the circumstance that they were originally detected in infusions of vegetable substances. More careful investigation, however, has shown that the organisms thus hastily associated together differ widely from each other; and that many of the tribes are, on the whole, more nearly related to the vegetable than to the animal world. Moreover, amongst those whose animal nature is perfectly obvious, the differences which have been observed as to organization are so great, that while roost of the number take rank with the very humblest forms of sentient beings, others, again, present a much more complicated structure, and are now properly classed with the higher divisions of the invertebrate animals, minute though they be, and, in this respect, true animalcules. It would seem, indeed, that the earlier investigators of this invisible world of organic life were so elated with the remarkable discovery they had in charge, that they were disposed to regard everything belonging to it as perfectly unique, quite separate and distinct from all that had previously been known. No matter, therefore, what the objects were that came within the field of their microscopes the eggs and larva? of insects, the germs of embryo polyps, the spores of fungi, and many different forms of mature plants, together with other matters of a still more heterogeneous character all were alike set down as being organisms of the. same general cha- racter, and regarded as equally belonging to this newly discovered world of Infusorial Animalcules. It affords a curious illustration of the union of great powers and special aptitude for delicate research with unaccountable proneness to deception, that Ehrenberg, the great microscopist of Berlin, and for many years the almost undisputed authority on, 4 EHRES BERG'S MISTAKES, the Infusoria, was beguiled into more errors of the kind above alluded to than almost any other observer. In his great work, " Die Infusionsthierchen," published in 1833, and which, with all its imperfections, is undoubtedly a splendid monument of his industry and genius, there are perhaps a greater number of as- sumed discoveries which no subsequent observer has ever been able to confirm, and a greater number of inferences which are now discarded, although deduced from acknowledged phenomena, than are to be found in any similar work in the whole com- pass of modern science. And yet, when first published, this work seemed so complete and so exhaustive of the subject, that it was some years before any one doubted either the correctness of the observations or the soundness of the conclusions of its author. The name of Ehrenberg was a sufficient guarantee for any state- ment, however marvellous, and his reputed discoveries passed for a time unquestioned. Gradually, however, as the number of observers increased, and as various improvements were made in the construction of the microscope, the views of the great Berlin philosopher were discovered to be in many particulars erroneous, and that one of the two great characters on which he had relied for separating the Infusoria into their main divisions, was alto- gether imaginary. According to the classification adopted by Ehrenberg, the Infu- soria formed two principal and well-defined groups. To the first of these he gave the name Polygastrica, from the supposition that all the animalcules composing it possessed several distinct stomachs, united together by a sort of intestinal canal. The second group consisted of the Wheel Animalcules, so named on account of the wheel-like rotation produced by rows of delicate hair-like bodies, resembling eyelashes, and hence termed cilia, which fringe the upper extremity of the bodies of the animal- cules ; and to these Ehrenberg gave the name Hotatoria, or Ilotifera. In these two groups, as the primary divisions, all the Infusoria were included ; and though Ehrenberg was fully sensible of the great dissimilarity between the organization of the Eotifera and that of the various forms included in the other group, he seems to have had no doubt as to the perfect propriety of their being all retained under one and the same general designation. Never, however, have the views of a philosopher, or his supposed discoveries, been more completely set aside by subsequent observa- THE POLYGASTRICA. 5 tion than is the case with those of Ehrenberg in this his chosen field of research. The Rotifera are now, by common consent, ranked with the lower divisions of the Articulate animals, with which, as Ehren- berg himself had pointed out, their complicated structure evi- dently brings them into close relation ; so that thus, at a stroke, .one of the two great primary groups of the Infusoria has been taken away. Then, with respect to the Polygastrica, although their rejection as a division of the Infusorial Animalcules has been neither so summary nor so complete as that of the Rotifera, their treatment by the most competent observers of the day is, in every respect, far more damaging to the authority and in- fluence of the great microscopist of Berlin. In the first place, it is now generally allowed that the term Polygastrica is altogether inapplicable, inasmuch as no such multiplicity of stomachs as was alleged is found to exist in any of the organisms to which it was applied. Ehrenberg was led to the opinion he entertained on this point by a somewhat curious expedient, first adopted, we believe, by Baron Gleichen, and which certainly exhibits his ingenuity and fertility of re- source in a very favourable light. A very general characteristic of these so-called Polygastrica is, that they exhibit, in the interior of their substance, a number of clear spaces, resembling so many minute sacs in some of the species these vacuoles, as they are termed, numbering upwards of a hundred. It occurred to Ehrenberg that possibly these vacuoks were stomachs ; and, in order to test the accuracy of his conjecture, he tried the experi- ment of feeding the animalcules, employing for the purpose coloured substances, such as carmine and indigo, the particles of which, if imbibed, would, he knew, be readily discernible through the gelatinous substance of the animals' bodies. The experiment was perfectly successful. The delighted philoso- pher saw numbers of the minute beings coursing over the field of his microscope, with little specks of colouring matter dis- tinctly visible within them. P^hrenberg had now no longer a doubt that the internal clear spaces were really stomachs ; and, rendered enthusiastic by his singular discovery, he subsequently saw, or rather fancied he saw, distinct traces of a connecting intestinal canal. No wonder, therefore, that from characters so marked and 6 DELUSIONS DISPELLED. peculiar, Ehrenberg derived a name for the entire class of organisms in which they obtained. But, unfortunately, the ablest observers since then, using the most powerful microscopes, have come to quite different conclusions with respect to the nature of the internal clear spaces, and have to this day failed to discover the assumed connecting canal. It is evident, indeed, that no such structure exists, and the term Polygastrica, there- fore, is totally inadmissible. More than this, however, many tribes that were so designated are now known to be true plants, while others still form the subject of debate between the botanist and the zoologist ; and another large section have been ascertained to be merely active germs, some of aquatic plants, others of worms or various insects. It is not too much to say, therefore, that by far the larger proportion of the organisms which Ehren- berg placed amongst the Infusoria as Polygastric Animalcules, are strictly referable to other and widely different groups ; whilo in none of them is there to be seen that complicated and mar- vellous digestive apparatus from which, the class, as a whole, received its designation. The Infusoria, then, viewed as Ehrenberg regarded them that is, as minute animals, and admitting of being arranged in two well-defined and homogeneous groups are blown to the four winds. The classification is altogether at fault. But the various beings thus arbitrarily associated together exist none the less ; and though they are in some respects, perhaps, a little less marvellous than the spurious discoveries of former times had led us to suppose, there is little need to surround them with ima- ginary wonders, in ord*er to their commanding a deep and per- manent interest. Nor is this at all the less true from our now having to regard many of these minute organisms as belonging rather to the vegetable than to the animal world. Plants or animals, it matters little their extreme minuteness, the extra- ordinary abundance in which they swarm around us, the variety, and, in many cases, the great beauty of their structure, all con- duce to render them objects of the greatest interest, and to make the study of them one of the most attractive departments of natural science. Let us then without caring much about classification mind- ing only to keep in view the great leading distinctions which recent research has established, look more in detail at the eco- PLANTS, OR ANIMALS ? 7 nomy of these microscopic beings, and at the various wonders which they display. It may seem an odd way of beginning a volume on the curi- osities of animal life to commence with an account qf objects which belong to the vegetable kingdom ; but all things con- sidered, the proceeding is by no means so Hibernian as may at first sight appear. The truth is that, in dealing with these minute forms of life, we are venturing on what has aptly been called the border land of the organic world the frontier territory, so to speak, which lies between the two great kingdoms of animated nature ; and, as in many another case of disputed boundary, the inha- bitants of the debatable region have sometimes been claimed for the one side and sometimes for the other ; and in this case it has so happened that many of them have occasionally been claimed with equal vehemence by both sides at once. The dispute as to what constitutes the essential difference between plants and animals can hardly yet be said to have terminated ; and though there is now a very general concurrence of opinion that the distinction mainly consists, on the one hand, in the dependence of the being for nutriment on organic substances already formed, which in some way or other it takes into the interior of its body, and, on the other hand, in the possession of the power to obtain its nourishment by absorption from the in- organic elements on its exterior ; yet this is a test which, in the nature of the case, is exceedingly difficult of application to these microscopic organisms. The power of spontaneous motion, Avhieli was at one time relied upon as a distinguishing mark of animal life, has long since lost its value in that respect, as it is now well ascertained that not only the early immature forms, but the fully developed individuals of many of the simplest aquatic plants arc endowed with very active powers of locomotion, and, to all ap- pearance, dance as merrily through the water as any of their compeers of the animal series. It has been argued, again, that the presence of what are known as contractile or pulsating spaces in the interior of the body is a proof of animality, but here also the progress of research has gone against the assumption, these contractile spaces being now known to be common to lx>th the animal and the vegetable kingdoms. Owiug to this appa- rent animality of many of these humble plants, it is extremely 8 THE TWILIGHT MONAD. difficult, and, in many cases, absolutely impossible, without carefully tracing out the entire life-history of an organism, to determine satisfactorily whether it belongs to the animal or the vegetable kingdom. The proper position of most of these microscopic beings, it is true, is now pretty well ascertained ; but there are still doubtful races which may yet change sides, and pass from amongst the plants, to be henceforth regarded as animals ; or, which is more probable, cease to be ranked with animals, to take their place henceforth with the plants. It will be a quite excusable licence, therefore, to include both sides in our present review, the more especially as, at one time, they were all alike regarded as tine animals, and still equally belong to that unseen world of organic life with which we are now concerned. One of the most recent results of the investigation which has been carried on into the history of these minute organisms has been to hand over from the animal to the vegetable kingdom the entire tribe of the so-called Monads, which, both in their simple and in their associated forms, have long attracted the attention of microscopical observers. The simplest and most minute of these organisms is the Twilight Monad (Monas cre- pusculum), which, seen under glasses of the highest magnifying power, is still a mere speck of pellucid matter, which is known to be possessed of life only because of its vigorous and animated movements. It has a diameter of not more than the twenty- four thousandth part of an inch a measure of magnitude, or rather of its opposite, which is easily expressed in words, but of which the mind is utterly unable to form any definite con- ception. But it is not in respect to size alone that these minute beings are so remarkable, their amazing abundance is no less extraordinary. It is no uncommon thing to find them crowding the water in which they occur, to such an extent that they are separated from each other by a space no greater than their own diameter; so that a single drop of the fluid would contain, it is estimated, some hundreds of millions of living beings ! When the animal nature of the Monads was generally admitted, this remarkable abundance and minuteness combined invested them with a great degree of interest, and they were not inappro- priately regarded as the starting-point, so to speak, of animal life the point at which its first feeble glimmer became distin- FISH ANIMALCULES. 9 guishable from the darkness of nonentity. The Monads are, for the most part, of a round or oval form, and in all the larger kinds a distinct tail-like appendage is discernible, which was supposed to be at once an organ of motion and a means of obtaining food. One tribe, however, which was included in the genus Euglena, bear a close resemblance to fishes in shape, and being provided with a large red eye-spot, they pass very well for " Fish Ani- malcules." It frequently happens that these tiny representatives of the finny tribes are congregated in such vast profusion as to impart to the water in which they occur a very perceptible tinge of colour ; and Ehrenberg fancifully suggests that it was probably by the agency of one of them, which from its colour has earned the name of Euglena sanguined, that the miracle recorded in Exodus, of turning the waters of the Nile into blood, was effected. The commonest of these Fish Animalcules in our own ponds and ditches is E, viridis, which, with its grass-green body and its carmine eye-spot, is a pretty object in the microscope, and one that may be observed with great interest, even tliough we may no longer believe with Ehrenberg that its " eye " is a real visual' organ, or that the clear spaces within its body constitute a lond fide digestive apparatus. In the heat of summer, the surface of stagnant pools often becomes covered with a thin film of scum, which looks to the naked eye like a coating of fine dust, but which, on being care- ful ly removed and examined by the aid of a powerful microscope, is seen to consist in great part of various minute organisms, which, when disturbed, move briskly about in the water. A large proportion ef the number are Fish Animalcules of the kind just alluded to ; but, in addition to these, there are others of a larger size, closely allied to the Monads, but presenting some most extraordinary complications of structure. They are in fact compound structures, consisting of Monads grouped together in clusters, and imbedded in the interior of variously shaped gela- tinous masses, which swim about by the united action of their tail-like appendages. One of the most curious of these is the Oonium pectorale, commonly called the High Priest's Breast- plate, which consists of a combination of sixteen monadiform. bodies, disposed regularly in a four-cornered tablet, like the jewels in the breastplate of the Jewish high priest. Another, and still more beautiful variety, is the Pandorina morum, in 10 AN ANIMATED CRICKET-BALL. which the investing gelatinous mass is of a globular form, and encloses about thirty Monads of a dark-green colour, which have a peculiarly elegant appearance in the centre of the transparent sphere." It is a terrible coming down from the romantic views of Ehrenberg, no doubt, to assign these various bodies, simple and compound alike, to the vegetable kingdom, but such is un- questionably their true position 5 for they are now ascertained, beyond all reasonable doubt, to be nothing more than the suc- cessive stages of a humble plant the Protococcus pluviulis; the so-called simple monads being merely the early " motile " or active germs of the plant, and the compound or associated forms the subsequent phases which the plant assumes by the continued self-division of its original cells. But a far more extraordinary example of these composite vegetable structures, formerly ranked with the Monads, is the famous Volvox glolator, which has not unnaturally excited more astonishment than any other member of this most strange association of organisms. The Volvox is by no means uncommon in our ponds and ditches, and as it attains a diameter of one- thirtieth of an inch, it may easily be detected by the naked eye when the drop of water containing it is held to the light. Seen in this manner, the Volvox appears a minute green globule gently moving about in the water ; but when viewed with a moderate magnifying power, the globule is seen to be a hollow pellucid sphere, studded at regular intervals with minute green spots, from each of which proceed two long cilia, by the united action of which the little globe moves through the water. Ordinarily it moves onward with a rolling kind of motion, a sort of self-bowling cricket-ball ; but occasionally it glides along without turning on its axis, and more rarely still, it may be seen twisting round like a top without changing its position. In the interior of the Volvox a number of smaller globes may generally be seen, some adhering to the inner surface of the investing sphere, and others, more advanced, lying freely within the cavity, revolving like satellites, not around, but within the parent sphere. If the ob- servation be continued for a short time, the larger globe will be seen to burst, when the imprisoned globules float freely away to begin an independent existence. Long after the Volvos was quite familiar to microscopical THE VOL VOX GLOBATOR. 11 observers, the whole exterior globular mass was regarded as a single animal, and the bursting of the globe, and consequent escape of the contained globules, as its ordinary mode of increase. Ehrcnberg, however, was the first to ascertain that the Volvos is really a coniposite structure, made up of an association of or- ganisms in every respect similar to each other ; but then he made the mistake of regarding them as true animalcules, and described them as being each possessed of an eye, a mouth, and several stomachs. The truth is that the Volvos has now been ascertained to be a composite vegetable structure closely allied to the Protococcus, and that its growth and development, together with the production of the contained globules, is, as in the case of the various forms of that plant, due to the repeated self-division of its component cells. It can hardly be said, however, that the discovery that the Volvox is a plant rather than an animal at all diminishes the wonderfulness of its structure and history ; for in whatever light we may regard it, it is certainly one of the most extraordinary organisms with which even the microscope has made us acquainted. But there is another wonder to be added to its history even yet : the Volvox, it appears, is sometimes found to be infested with parasites ; and on one occasion a specimen was observed, in the interior of which two minute Wheel Animalcules were distinctly visible. No opening could be perceived by which they could have found entrance, nor did there appear to be anything with- in to impede their movements ; on the contrary, they swam about as freely as fish in a glass globe, to which, indeed, they are said to have had no faint resemblance. Mr. Pritchard, in his " History of Infusorial Animalcules," stoutly contends for the animal nature of these beings, and ap- propriately concludes his account of them with the remark, " Who can behold these hollow living globes revolving and dis- porting themselves in their native element, with as much liberty and pleasure as the mightiest monsters of the deep, and not exclaim with the Psalmist, ' How wonderful are thy works, Lord ; sought out of all them that have pleasure therein ' ?" Nothing is more remarkable in connection with the Protoplnjta, or simplest forms of plants, with which we arc now dealing, than the extraordinary and altogether unplant-likc shapes which they assume. This is sufficiently striking in the Volvox and its allies 12 DESMIDS AND DIATOMS. already noticed, but it becomes still more obvious in the two tribes to which we now pass on, namely, the Desmidiacece and the Diatomacece, or, as we will style them, the Desmids and the Diatoms, in which stars, crosses, triangles, and other graceful geometrical figures take the place of the more ordinary vegetable forms, and give to these tiniest of plants the appearance of so much mimic jewellery. The Desmids are green gelatinous bodies, confined exclusively to fresh water. In most cases they consist of a single cell, which is nipped in, in the middle, like a young lady with a small waist, while the outer surface is frequently projected into spines and variously-formed processes, which present a very symmetrical and elegant appearance. It has recently been discovered that a regular circulation of fluid takes place in the interior of these minute organisms ; and it may interest the reader to know that the gentleman to whom we owe most of our information on the subject is no other than the redoubtable S. G. 0. of the " Times ' newspaper, who, it appears, is wont to relieve his severer occupa- tions by an occasional turn to the microscope, or the inmates of the aquarium. The Desmids perpetuate their race in three distinct fashions. In the first place, they multiply themselves by the process of self-division ; secondly, by the breaking up of the " endochrome," or coloured contents of the parent cell, into a multitude of granular particles, which are set free by the rupture of the cell wall, and then start in life on their own account ; and, thirdly, by the process known as "conjugation," which may be regarded as the first foreshadowing of the true sexual union which takes place in the higher plants and animals. In many respects the Diatomacecp, have a close affinity to the preceding group ; but they are unmistakably separated from them by the possession of a bivalve shield, of pure colourless silex, which renders their forms indestructible. It is to the posses- sion of this silicious shield that the Diatoms owe all their beauty and importance. There is a wide diversity of form in the shields of the various species ; but in all of them alike the surface is sculptured with a beautiful, well-defined, and more or less com- plicated pattern of lines and points, which afford a ready means of distinguishing the different species, and at the same time places these minute bodies amongst the most elegant of micro- scopic objects. In many of the species the individual Diatoms RAPIDITY OF INCREASE. 13 or " frustules," as they are also termed, are entirely disconnected from each other, but in others they are. united together in con- siderable masses in a sort of gelatinous envelope, and in others, again, they are variously united into composite structures, which sometimes present an appearance of great elegance and beauty. In the more simple of these associated tribes, the frustules are merely held together in long filaments, or zigzag chains ; in others, they are arranged, side by side, in flat bauds or beautiful screw- like coils ; while in some very elegant forms they are mounted on slender foot-stalks, and have the appearance of clusters of tiny fans, every ray of each separate fan consisting of a perfect Diatom enclosed in its silicious shield. Like their allies the Desmidiaceee, the Diatomacece increase both by self-division and by conjugation, and so rapidly does their multiplication proceed, that one of the most cautious of micro- scopical observers has calculated that, in the course of one month, the progeny of a single Diatom would amount to the amazing number of one thousand millions ! This extraordinary rapidity of increase will readily account for the sudden appearance of vast numbers of these organisms in localities where, only a short time before, they were either not to be found at all, or occurred but sparingly ; it will also help us to account for those vast accumu- lations of their silicious shields which are being formed in various parts of the ocean at the present day, and the still more extensive deposits of similar exuvias which originated in remote geological epochs. It has already been mentioned that the shields of the Diatomaceas are indestructible. Unlike, therefore, to multitudes of higher organisms, which live their day and then disappear, leaving no trace of their existence behind them, every one of these lowly beings deposits in the water it inhabits an imperish- able memento of its brief life, and not unfrequently contributes to the formation of rocky strata, which, in the remote future, may give a distinctive character to countries yet unborn. In some places the accumulations of these remains are exerting an important influence in blocking up harbours, and diminishing the depth of channels; and, according to the observations of Professor Bailey of New York, various portions of the bottom ol' the North Pacific Ocean are being covered up by deposits of a similar character, in which the two valves of the shield are frequently found still united, and containing remains of the 14 IKFDSORIAL EARTHS. internal soft parts. But the most remarkable of tliese deposits of diatomaceous remains, now in process of formation, is that which Dr. W. J. Hooker has made known in the southern seas. Dr. Hooker states that the waters of the Antarctic Ocean, between the sixtieth and eightieth degrees of latitude, abound with Dia- tornaceas to such a'degree that the sea, over large portions of this wide area, is literally stained with them ; and that their shields ai-e gradually producing a submarine deposit which flanks the Victoria Earner, and covers a surface four hundred miles long by one hundred and twenty miles broad ! This immense mass of diatomaceous remains is in close proximity to Mount Erebus, an active volcano, twelve thousand feet high ; and the circumstance has suggested to Dr. Hooker whether there may not be some direct communication between the ocean- waters and the internal fires of the mountain, such as would account for the curious but well-established fact, of the occurrence of the silicious shields of the Diatomacece in the ashes and pumice of many active vol- canoes. These immense submarine deposits of the shields of the Diatomacea? may be said to be rocky strata now in the course of formation. But similar deposits are found in many of the exist- ing rock-formations of the earth's crust, and in some cases they constitute by themselves beds of considerable thickness. The so-called " infusorial earths " of various parts of the globe are all of this description. One of the best known of these earths is the famous berymehl, or mountain meal of Sweden, which, in times of scarcity, the inhabitants are accustomed to mix with their flour in making bread ! The Tripoli or rotten-stone, used in polishing metals, the well-known Turkey-stone, and the Polierschiefer, or polishing slate of Bilin, in Bohemia, are also examples of fossilized remains of the Diatomacefe, the last-men- tioned material occurring in a series of extensive beds averaging fourteen feet in thickness. Again, the city of Richmond, in Virginia, is said to be built on a bed of diatomaceous remains, eighteen feet in thickness and of unknown extent ; while in 1839, Ehrenberg astonished the inhabitants of Berlin with the discovery, that just beneath the foundations of their houses there was an immense deposit of a similar character ; excepting that, in this case, to add wonder to wonder, a large proportion of the mass consisted of Diatomacea) LITTLE CHAH6EABOUT. 15 still alive and active, sustained, no doubt, by the water which finds its way to them from above ! But perhaps the most curious situation in which these remains have yet been found is in the guano which is brought from the coast of Africa and Peru. Great numbers of the frustules have been found in this material ; and it has been conjectured,* with considerable probability, that the peculiar value of guano in the growth of cereals may greatly depend on the presence of these minute organisms, inasmuch as they supply it with that extra amount of silica which all the corn-plants require. Thus, if this conjecture be well founded, these minute beings, after perform- ing their part in the economy of nature while alive, and then lying entombed amidst a feculent mass of animal exuviai for perhaps thousands of years, at length reappear, to add fertility to our fields, and to multiply the means of human subsistence. Leaving, now, those sections of these microscopic forms of life which have been handed over to the botanist as properly be- longing to the Vegetable Kingdom, we pass on to the true Animal- cules. We have already seen, however, how vague and inappro- priate is this term, as referring solely to the minute size of the organisms embraced by it, and in no degree marking their grade in the scale of being. The reader will not be surprised, there- fore, to learn that this term is now discarded as of no value, while for the simplest of these truly animal forms which were originally comprehended by it, the name of Protozoa has been adopted ; thus marking their position at the very base of the animal series, as the corresponding name ProtopTiyta expresses the rank of the simplest forms of vegetable life. Beginning our survey of the Protozoa with those lowest in the scale, we take the little Amoeba (Amceba dijfluens), formerly known as the Proteus, and famous amongst microscopical obser- vers for its incessant change of form. This little creature is com- monly to be met with at the bottom of ponds of clear water, and to the naked eye appears a mere animated dot of jelly. It is re- markable for the extraordinary simplicity of its structure, consist- ing wholly of a granular gelatinous substance named sarcode, and having neither head, nor mouth, nor stomach, nor special organs of any kind whatsoever. It has not so much even as an investing membrane or skin, its outer surface exhibiting no trace of any structure at all firmer in consistence than the rest of the body. 16 THE ACT1NOPHRYS SOL. But although presenting thus scarcely any marks of distinct or- ganization, the Amoeba is by no means the dull and uninterest- ing creature that one would be apt to imagine. Its most obvious peculiarity, indeed, is the facility with which it incessantly alters its form ; long finger-like processes being pushed out first from one part and then from another, the body of the animal mean- while gradually flowing, as it were, into these divergent portions, and so progressing irregularly from point to point of the surface on which it rests. One would suppose that an animal so exceedingly simple in structure, and so apparently helpless, would be a very inoffensive neighbour ; but the truth is that, in its small way, the Amceba is quite a terror at the bottom of our ponds and ditches. Its special weakness in the matter of diet appears to be the Diato- macejE ; but nothing comes amiss : and, as it goes shambling along in its uncertain way, over the surface of the mud or the stems aud leaves of the aquatic plants, it DO sooner meets with any object suitable for food than it proceeds very deliberately to wrap its body around it, nor is the prize again relinquished until all its juices have been extracted, the entire surface of the ani- mal taking part in the appropriation of the nutriment. In another of these simplest Protozoa, closely related to the Amceba, the finger-like processes, or pseudopodeee, as they are termed, take the form of simple threads, which radiate from the spherical body of the animal, and give it much the appearance of the " Eising Sun," as artistically represented on the signboards of our wayside inns ; whence it is no doubt that the animal in question has received the appropriate name of Actinoplirys sol. The Actinophrys is a far less vivacious creature than its pro- tean ally, and rarely does much in the way of locomotion, while its filamentary pseudopodeaa are usually kept rigidly pro- truded. It is by these threads, however, that the animal secures its provender, and directly one of the number seizes hold of any minute object of a nutritious character, it forthwith begins to retract itself, and is presently joined by the neighbouring fila- ments, which coalesce with each other, and thus actually imbed the prey in their gelatinous substance before it has reached the surface of the captor's body. Once there, however, it is carried by means of an opening improvised for the purpose, into the interior of the body, whence the indigestible portions are in due MANY-CHAMBEKED SHELLS. 17 time pushed out, much after the manner in which they werp at first drawn in. The class of animals to which, the Amoeba and the Actino- phrys belong, comprise two great divisions, in one of which the ani- mals are simple, and in the other associated together in compo- site structures, forming, as it were, a common body, though it is not improbable that each segment of the composite animal still retains, to a certain extent, an independent existence. Most of the solitary kinds are lodged in a horny capsule or shell, which, in the different species, assumes a flask-like, bell-shaped, or globular form, through a narrow opening in which the enclosed animal projects its gelatinous pseudopeas, whether in search of food or for the purpose of locomotion. The composite species are all enclosed in calcareous shells, which, though in most of the forms exceedingly minute, are yet of a very complicated structure, and exceedingly beautiful objects for the microscope. These shells are divided into a number of distinct chambers, and are perforated with numerous foramen, or holes, from which characters they derive their two technical names of Polytha- lamia, or many-chambered, and Foraminifera, or perforated, shells. The circumstance that these tiny structures consist of several chambers arranged in various spiral forms, like the shells of the Nautilus and its extinct allies, led to the belief at one time that the animals inhabiting them were microscopic members of the Nautilus family. But more accurate examina- tion has shown that, unlike what is seen in the Nautilus, every chamber of these microscopic shells is inhabited ; and that the occupant of each chamber is, in some sort, an independent being, which throws out its delicate filaments through the perforations of its chamber-walls, just as the Amoeba does from the naked surface of its body. All the Foraminifera are inhabitants of the sea, and in some 1 tarts they abound in such vast profusion as to be gradually producing extensive deposits of calcareous matter by the accu- mulation of their almost invisible shells. The remarkable eleva- tion which stretches across the bed of the Atlantic, between Cape Clear in Ireland and Cape Race in Newfoundland, and which is now well known as the " telegraphic plateau," from the circumstance that it was upon this ridge that the Atlantic telegra- phic cable was laid in the summer of 1858, appears to be thickly c 18 MICROSCOPIC GEOLOGY. covered with, if it does not in great part consist of, these infi- nitesimal structures. And Professor Baily, who has carefully examined the soundings brought up from this sub-oceanic table- land, states that they consist entirely of microscopic shells, with- out a particle of sand or gravel, and that with the exception of a small number of the silicious shells of the Diatomacese, the entire mass of the soundings consisted of the perfect calcareous shells of the Foraminifera ; a fact which is all the more remark- able from the striking contrast it presents to the deep-sea sound- ings from the Pacific, before referred to, which are chiefly made up of the silicious shields of the Diatomacese. But this is not all. In former epochs of the earth's history the Foraminifera existed in even greater profusion than at present : and their remains form the principal constituent of some import- ant geological formations. In many of the tertiary strata they occur in the greatest abundance. " It may even be asserted," says Professor Ansted, " that the capital of France, as well as the towns and villages of the neighbouring department, are almost entirely built of Foraminifera." But it is in the chalk more especially that these minute shells chiefly abound ; recent observations having shown that this material is everywhere, in great part, and in several districts almost wholly, composed of them, either still perfect, or nearly so, or else broken and ground down to a fine powder. Now, let the reader make an effort to realize this fact in respect to the chalk formation, as it is developed in England alone. Let it be remembered that this material occurs over nearly the whole of the south-eastern part of the island, and that in many places it has a thickness of several hundred feet, and then let the reader form an estimate, if he can, of the number of these fragile and delicate shells which lie buried within our far-extending ranges of chalk hills. But turning from these vast accumulations of the microscopic life of the ocean of the chalk epoch, let us come back again to our own ponds and ditches, and to the living wonders with which they abound. One can hardly characterize as " pets " creatures so exces- sively minute as those with which we are now concerned ; but if there be any one of the number which more than another deserves the name, it is, undoubtedly, the " Bell Animalcule " ( Vorticella), a prime favourite with every owner of a microscope, THE BELL ANIMALCULE. 19 and one of the most curious of that restricted group of organisms to which the term Infusoria is now applied. It is a little bell of glassy transparency, with a broad and thick rim or lip, affixed by a sort of nipple to a slender filament or stem, eight or ten times its own length. The mouth of the bell is surrounded by a fringe of cilia, which can be withdrawn at pleasure, but which, when protruded, are kept in rapid play, producing a sort of vortex in the water, by means of which minute particles of alimentary matter are drawn into the mouth of the animal. The long, slender, and flexible stems of these beautiful animals are attached to the stalks or leaves of aquatic plants, where the Vorticella} are frequently crowded together in such numbers as to cover the parts with what looks to the naked eye like a deli- cate white down. When not disturbed, the little Vorticella stretches out its slender stern to the full extent, and turns gracefully about in the water, keeping its cilia meanwhile in constant motion. But on the least alarm, the cilia vanish, and the stem, with a rapidity which the eye can scarcely follow, is contracted into a beautiful spiral coil, so as to bring the bell close to the point of adhesion, when it again gradually uncoils to its full length. It is hardly possible to exaggerate the beauty of this spectacle, when a group of the Vorticellse are viewed together by the aid of a powerful microscope. At first the little creatures are seen floating loosely through the water, most of them having their delicate stems fully extended, or showing only slight undulations, and the bells slowly roaming about, now turning the mouth, now the sides, and now the foot, to the eye of the observer : suddenly, however, and at the slightest tap, the entire throng start back, and before the eye is well able to discover what has occurred, the glis- tening bells may be seen closely nestling around the stalk of the plant to which their stems are attached, gently swaying from side to side, and beginning again to uncoil and stretch out as before. The history and development of the young Vorticella are fully as curious and interesting as the habits of the mature animal. In all these microscropic beings the ordinary mode of increase is by the parent animal separating into two or more parts, each of which speedily attains to the dignity of a parent itself. In the Vorticcllaj this process of self-division begins in a 20 REPRODUCTION OF VORTICELL^E. gradual widening of the bell, which then assumes a globular shape, and next that of a flattened sphere ; at which stage of the process a band-like constriction makes its appearance in the middle, and gradually increasing in depth, it at length separates the original animal into two, both of which still remain attached to the stalk. But as only one of the two is to remain in pos- session of this piece of joint-property, the subsequent develop- ment of the two animals is singularly dissimilar. In the one which is to retain possession of the original stalk, the upper extremity opens out into the regular bell-mouth form, around which the fringe of cilia are speedily seen in active motion : in the other, on the contrary, the upper extremity still remains closed, and the cilia are developed at the lower extremity near the junction with the stalk, from which the young Vorticella now speedily shoots away, a free, swimming animalcule. Its roving life, however, is soon over ; for looking out a convenient spot for its future home, it speedily settles down, and attaching itself by what was at first the upper part of its body, it gradually rises on a stalk of its own, and in due time becomes a fully developed Bell Animalcule. Another curious mode of reproduction amongst the Vorticella?, as amongst some other tribes of these minute organisms, is by what is known as the encysting process. In this mode of obeying the injunction to " increase and multiply," the Vorti- cella withdraws the ciliated margin of the bell, and contracting itself into a cyst or purse, secretes a gelatinous covering, whicli gradually solidifies, and forms a sort of capsule within which the animal is completely enclosed. In this state it remains for some time, it may be only a few hoxirs or it may be clays, in the course of which the substance of the original animal becomes broken up, so to speak, into a number of minute oval bodies which move about with great activity within the transparent cyst. At length some portion of the cyst Avail gives way, and the im- bedded embryos suddenly shoot out into the water, where they become diffused, and give rise to a new generation of Vorticellte. She power of enclosing themselves in a cyst is sometimes em- ployed by the Vorticella; for the purpose of self-preservation, when the water in which they have been residing dries up. In such cases the enclosed animals are preserved from injury till the falling rain again fills the pool, and calls them back to active life : TRUMPET ANIMALCULES. 21 or it may be, they are taken up by the wind with the dust which arises from the parched ground, and conveyed to great distances before they are again brought to the surface of the earth by the descending shower. The Vorticellaj form altogether a very considerable family of animalcules, and present several beautiful varieties of structure and arrangement. In one section of the family the animals are grouped together on branched tree-like structures, composed of many individual Vorticella?, each connected at the extremity of its spiral foot-stalk, and maintaining to a certain extent an inde- pendent existence, but all united at the base on one common stem. The members of another group, instead of being affixed to spiral foot-stalks , are seated in elegant crystal vases, attached to the stems and leaves of aquatic plants. The animal is united to his tube or vase only at the base, and can at pleasure protrude himself above its open top, or, in the twinkling of an eye, con- tract himself into a little shapeless ball at the bottom. It is not at all unusual to find two animalcules occupying a single case, this double occupancy being no doubt attributable to some little hitch or misadventure in the process of self-division. It is satisfactory, however, to know that, so far as can be ascertained, the original inhabitant and the half of his former self live very amicably together, and do their best to make each other as com- fortable as may be under the circumstances. In close companionship with the Vorticella? we may often find some interesting relatives of theirs which we must now briefly notice. In the first place there are the Stentors or Trumpet Ani- malcules, so called from the trumpet-like form which they assume, and large enough to be seen by the naked eye. There are several kinds of these animals, which are distinguished from each other in part by their colour, one variety being little Ethiopians. They are very common in ponds and ditches, where they attach themselves to duck-weed, decaying reeds, and other floating bodies, around which they form a sort of slimy fringe. In swimming about, the Stentors contract themselves into the form of an egg, and row themselves along by the cilia which clothe the entire surface of the body ; but when they attach themselves, they stretch out, and stand erect, like so many mimic trumpets. If a number of these animalcules be examined in a small quantity of water, they will often be seen to congregate, 22 WHEEL AMIMALCULES. and swim about in company, then apparently to take counsel together, select a particular spot, and all of a sudden attach themselves in a group, where they stretch up to their full extent and begin bowing and salaaming to one another. in the most polite and courteous manner imaginable. Next we have a division of these animalcules, in which the surface of the body is covered with an array of bristling spines and hooks, by means of which their owners creep and climb about amongst aquatic plants ; in another group we meet with a singular apparatus, consisting of a circlet of bristles -which sur- round the mouth, and has hence received the name of teeth, but which appear to be organs of prehension rather than of any sort of mastication. Another tribe presents us with animalcules having an oval body and a long flexible neck, which the little creatures throw into graceful curves, like so many microscopic Swans, after which, indeed, they are named, one species giving us a veritable representation of that rara avis, the " Swan with two necks !" The Rotifera or Wheel Animalcules are, as we have already intimated, much more highly endowed than any of the preceding tribes, and excepting as to size, are not to be classed amongst the animalcules at all. But they are much too curious and interest- ing to be omitted from our survey of the various microscopic forms of life, and are therefore admitted here to the place which they occupied before their true position in the animal series was known. The discovery of the Rotifera was one of the earliest results of the application of the microscope to the study of these minute forms of life, nor is this at all remarkable, seeing that some of the species are as much as the twelfth of an inch in length, and readily descemible therefore by the naked eye. It is perhaps even yet premature to assume that the true position of the Rotifera has been satisfactorily ascertained ; but there can be no doubt that their true affinities are with the arti- culate sub-kingdom, in which they are now generally placed. The details of structure vary greatly amongst the different species ; but in all of them it is exceedingly complicated, and shows a great advance upon the simple forms of life with which they were formerly associated. In all there is a more or less distinct head, furnished with eyes and a mouth, from which a passage leads to a powerful masticating apparatus, in close proximity to the stomach, from which, in many species, proceeds an alimen- AN ANATOMICAL PUZZLE. 23 tary canal of a wonderfully complex character. The wheel-like organs from which the class takes its name are most character- istically seen in the Common Rotifer (Botifera vulgaris), and in this case consist of two disc-like lobes at the upper extremity of the body, the margins of which are fringed with long cilia, the organs specially concerned in the apparently rotatory move- ment. The singular appearance produced by the continued play of the Rotifer's cilia was for a long time a subject of inexplicable mystery to microscopical observers. It was as opposed to all known movements of organic structures as if a man's head should spin round incessantly on the top of his neck ; and yet there seemed to be no possibility of doubting that the two circular organs of the animalcule did thus revolve. After long and careful observation, the source of the illusion became apparent. The sup- posed wheels were found to be mere circlets of delicate cilia, which bending and unbending in rapid succession, like a field of corn on a windy day, gave rise to that wheel-like rotation which had proved such a fruitful source of perplexity and doubt. The Common Rotifer and its nearest allies swim freely through the water, rowed along with considerable rapidity by means of their ciliated lobes. They have the power, however, of at- taching themselves at pleasure, and at the lower extremity of the body they are provided, for this purpose, either with a cup-like sucker, or with a pair of minute forceps, by means of which they seize hold of the stems and leaves of aquatic plants, and rest for a time from theii more active exertions. But, fixed or free, it matters little to the Rotifer, for he has but to set those paddle- wheels of his in motion to produce a vortex in the water, which brings him food in abundance ; and yoii can rarely light upon one whose cilia have been long at work in capturing, or rather collecting, prey, without finding that its masticatory apparatus also is busily employed tearing and pounding away at the mass of food with which its exertions have been rewarded. Many of the Rotifera are fixed to one spot throughout the en- tire period of their lives, and amongst these sessile forms are to bo found by far the most beautiful species which the race includes. One of the most elegant of these is the Stephanoceros Eichornii, which inhabits a delicate gelatinous tube, like the straight glasses used by the confectioners, to the bottom of which it is 24 BRICK-MAKING EXTRAORDINARY. attached by a long pedicle or foot-stalk, above which is the body of the animal, of an oval form, and surmounted by five long tentacles, beset with tufts of bristly cilia. This beautiful Roti- fer is of common occurrence, attached to aquatic plants, in ponds of clear water, and seen with a good light it is an object of which the observer never grows weary. More curious, perhaps, but less beautiful, is another of these sessile Eotifers, which inhabits a tube built up, particle by particle, by its own unwearied industry. The Melicerta ringens is a bom brick-maker, and no sooner starts in life as a respectable stay-at-home member of the great Rotifer family, than he proceeds forthwith to build himself a house in which to spend his days. The first step in the process, it appears, is to exude from the body a delicate gelatinous cylinder to serve as a sort of framework on which the more substantial structure is to be formed. This accomplished, the brick-making skill of the Melicerta is at once in request. Beneath a projection on the animal's head there is a small disc-like organ, which, when the ciliary lobes are in full play, revolves like the circular ventilator of a window. This is the brick-making machine ; and the animal so modifies the direction of the ciliary currents, as to send into it most of the solid particles which are drawn from the surrounding water. Here they are worked up, pro- bably with some peculiar glutinous secretion, and moulded into little globular pellets ; and no sooner is each pellet completed than the animal bends down its head, and applying the pellet-disc to the edge of the tube, deposits the newly-formed brick in its ap- propriate place. The finished tube consists of many hundreds of such bricks, and as each of them usually occupies about three minutes in making, including the collection of the materials, it is obvious that the Melicerta has no small amount of work to get through before it can complete its dwelling. It makes no undue haste, however, and its work is finished off with a neat- ness and regularity which are truly admirable. A very extraordinary circumstance connected with the Ro- tifera is their power of becoming revivified, after remaining for a considerable period dried up, and apparently dead, on being again moistened with a few drops of water. This extreme tenacity of life is so truly remarkable, that it has excited much attention, and led to many curious experiments. Fontana, an Italian naturalist, kept a number of the animalcules for two years and ATMOSPHERIC VOYAGERS. 25 a half in dried sand ; yet, in two hours after the application of rain-water, the greater part recovered life and motion. Some experimenters have been of opinion that the Rotifera may be really deprived of life, and kept in that state for many weeks, and yet be again restored to animation. Ehrenberg, Humboldt, and all eminent philosophers, however, entirely repudiate this idea ; and, quite apart from such testimony, we may be perfectly assured that the mysterious principle of life, no matter how minute the beings in which it has resided, is never once really extinguished without passing irrecoverably beyond all human means of recall, into the care of Him to whom alone belong " the issues from death." Our hasty survey of the microscopic life of the globe would be imperfect without a passing reference to the various minute organisms which are found floating around us, unseen, in the atmosphere. In greater or smaller quantities, the atmosphere always contains these invisible living atoms, their elevation from the earth's surface being sometimes effected by winds, at other times, probably, by ascending vapours. At times vast clouds of these beings are raised into the air, and carried by winds many hundreds of miles from the districts where they originate, rendering the atmosphere thick and heavy, and covering every object on which they fall with what appears to the naked eye a fine impalpable dust. In this manner myriads of forms, both of animal and vegetable life, are dispersed over the earth, and places before sterile and lifeless are converted into abodes of teeming and busy populations. And now let us prevail upon those of our readers to whom the subject of this Chapter may be to any extent new, to reflect a little on what has been brought before them. In spring and summer, for example, when they walk out by the sea-shore, and cast their eyes over the broad expanse of waters, let them remember that those mysterious depths are peopled with myriads of these minute beings, each as perfectly formed, and as beautifully adapted to the part it has to perform in the economy of nature, as the most exalted of organisms. In rambling, too, among green and shady woods, by fragrant hedgerows, or out upon the breezy heaths and open commons, everywhere let them recall the same fact, that, wherever they see, if it be only a few drops of standing water in every ditch, and pond, and crystal pool within and beneath all 26 PERFECTION IN MINUTENESS. that meets the eye there are multitudes of these tiny creatures, living, as it were, in a world of their own, though equally cared for by Him to whom there is neither great nor small. In view of these facts, we may well say with one of the most eminent of living philosophers, "If the astronomer be led from the con- templation of the countless orbs that traverse boundless space, to the adoration of the Creator in His almightiness, so the observa- tion of the perfection of His minutest works, which, though invisible to ordinary ken, unfold new perfections with every increased power of observing them, ought to impress us with a lively sense of that all-caring-for and all-seeing Providence with- out whom not a sparrow falls to the ground, and by whom every hair of the head is numbered." 27 CHAPTER II. A DISQUISITION OK JELLY-FISH. "Those living Jellies which the flesh inflame, Fierce as a nettle, and from that its name; Some in huge masses, some that you may bring Iii the small compass of a lady's ring ; Figured by hand divine there's not a gem Wrought by man's art to be compared to them ; Soft, brilliant, tender, through the wave they glow, And make the moonbeam blighter where they flow." POETS have rarely deigned to sing the praises of the Jelly-fish, which, perhaps, is one reason why there arc so few popular errors to correct concerning them. It is somewhat strange, certainly, but the bay-leaves and the professor's gown seldom do well together. The silk is almost sure to suffer. Perhaps it is that that " fine freuzy " in which the poet's eye is wont to roll has something to do with the matter. But, be that as it may, the fact is clear, and we seldom even expect to find correct science " done into " verse. In the passage quoted above, however, the amiable author of " The Borough " has given us a noteworthy exception to the rule ; and, in the compass of a few brief lines, has finely epitomized the leading points of Jelly-fish economy. Bear with us, good reader, the while we discourse to you for a brief space on these curious samples of ocean confectionery. No one that has paid an occasional visit to the sea-coast can be wholly unacquainted with the Jelly-fish. They are amongst the most familiar objects to be seen in rambling along the shore ; and, after violent winds, may often be met with, thrown upon the beach by the fury of the waves. In the calm bright days of summer, numbers of the commoner kinds may be seen gently flapping their way through the still water skirting the shore, their delicate and graceful forms alternately contracting and di- lating as they propel themselves along, and sometimes only faintly discernible from the water itself. 28 ABUNDANCE OF JELLY-FISH. It is hardly necessary to say, that the designation " Jelly-fish " is correct only in reference to the apparent nature of their sub- stance, and not at all in respect to any supposed affinity between these animals and true fish. They constitute, in fact, one of the humblest tribes of sentient beings, and appear to come but just within the limits of organic nature. Cast ashore, they exhibit not the slightest sign of life, and often pass amongst fishermen as " sea-blubber." But by far the most general of the popular names under which the Jelly-fish are known, are those which refer to the property which many of them possess, like the nettle, of stinging the hand that touches them. Hence it is that they derive the names of " stingers" " stang-fisJi" and " sea-nettles" amongst ourselves, and that of " Orties de mer " along the coast of France. It was from this circumstance, also, that Aristotle bestowed upon them the term Acalephce, the Greek word for nettle, which is still retained as the scientific designation of the entire class. The ocean swarms with these animals, from the equator to the poles ; and in the tropic seas the voyager often falls in with vast shoals of them, through which the vessel has to plough its way for many miles. At certain seasons of the year the Jelly-fish visit our coast in countless profusion, resorting principally to the bays and estuaries, whence stragglers are carried by the tides and currents to every part of the shore. In the year 1846, these animals suddenly made their appearance on several parts of our coast, in such extraordinary abundance as to embarrass the fisher- men in casting their nets ; and, after remaining for a while, they at length disappeared as mysteriously as at first they came. It is only as an occasional haunt, however, that these frail and delicate creatures approach the land ; their proper home is the open sea, where, driven by wind and wave, or wandering at their own sweet will, they roam the pathless waste, basking in the sun- beams by day, and at night lighting up the waves with their brilliant phosphorescent fires. One of the most remarkable things in connection with these animals is the extraordinary character of their composition. Nearly all the commoner kinds consist almost wholly of water. The only thing besides water which the most careful examina- tion of their structure reveals, is an exceedingly small quantity of filmy tissue, which, in the living animal, forms an intricate COMPOSITION AND STRUCTURE. 29 network of cells for the retention of the fluid part of its substance. Constituted in this manner, the Jelly-fish are of the most fragile and evanescent character. No sooner are they removed from the water, and no matter how carefully, than their delicate tissues be- come ruptured, and the contained fluid drains away, so that at the expiration of a few hours, of the whole bulky mass of trem- bling jelly, nothing remains but a thin pellicle of film, scarcely to be distinguished from an ordinary cobweb. It is a common amusement with boys on some parts of the southern coast, where these creatures are generally known as " water-blobs," to catch the smaller varieties, and hold them in the hand, while they thus gradually melt, as it seems, away. Dr. Carpenter states that large specimens, weighing, when first taken from the water, from fifty to sixty pounds, are reduced to a thin coating of filmy web, weighing scarcely as many grains. And what adds to the wonder is, that the fluid which escapes is in no way to be dis- tinguished, even when submitted to chemical analysis, from ordinary sea-water. Mr. Patterson, in his " Introduction to Zoology," relates an amusing case of a farmer, who had been in the habit of employing his men and horses in carting away from the sea-shore large quantities of Jelly-fish for the purpose of manuring his fields, and who, happening one day to hear a lecture in which the structure of these animals was explained, was not a little astonished to find, that in every ton of " sea-blubber," which he had been taking so much trouble to obtain, the entire amount of solid matter was scarcely more than he could carry home in one _f his coat-pockets. In none of these animals, so far as is yet known, is there any- thing like a distinct nervous system. Some few investigators have imagined that they could detect the presence of nervous threads or filaments, but the suspicion has never been verified, and the physiologist still ranks the Jelly-fish with the animals whose nervous matter, if they have any, is indistinct and beyond our powers of discovery. Respiration, too, is carried on by means equally obscure ; the probability being, that all the air required for the purpose is separated from the sea-water as it freely passes through the channels of the body. In some species there are some small red spots around the margin of the body, which are regarded as rudimentary eyes, although it is by no means certain that they are endowed with the power of vision. It is 30 BEAUTIFUL, BUT TREACHEROUS. said, however, that some of the smaller kinds have been observed to shun a bright light, and to sink into deep water to avoid it ; and our own schoolboy experience assures us that they are quite capable of " dodging " the hand that attempts to grasp them in the water. l In all the more typical forms of Jelly-fish, the body is more or less hemispherical in shape, with the margin in some species simple, in others beautifully scolloped ; while in many cases the animals are furnished with numerous long filaments, tubular tentacula or suckers, and a pedicle or proboscis, depending from the under surface. The stomach, in the form of a simple cavity, usually occupies the centre of the body, and has a small aperture immediately below, answering the purpose of a mouth. " In some species, however, the stomach occupies the thickest part of the pedicle ; and, instead of a mouth, the creatures are provided with suckers, having minute orifices at their extremities, through which they imbibe their nutriment, as plants do by means of their roots. Stranger still, there are some of these animals in which neither mouth nor stomach can be detected, the invisible food being absorbed by the countless pores with which the body itself is perforated, and in some mysterious manner, appropriated, it would seem, by all parts of the structure alike, Any one unacquainted with the habits of the Jelly-fish would be apt to form a very erroneous idea of their real character and disposition. Possessed of such a singularly delicate and beautiful frame, we should be disposed to credit them with all that is inno- cent and amiable, whereas they are in reality distinguished by qualities of a totally opposite character. Frail and lifeless as they seem when cast upon the shore, in their own proper element the Jelly-fish are powerful and destructive, and, in proportion to their size, may fairly be ranked amongst the most rapacious inhabitants of the ocean. By far the larger number of them subsist on living prey, and many of them upon animals far more highly organized than themselves. Even crabs and fish readily fall victims to their attacks ; the horny mail of the one tribe, and the shelly armour of the other, being alike ineffectual for safety, when once the captive is enfolded in the graceful ma- rauder's soft embrace. Nor is it the larger species only which are thus rapacious and destructive. Professor Forbes thus speaks of the truculent PLINY ON SEA-NETTLES. 31 behaviour of some specimens of a small Jelly-fisn not larger than a lady's thimble, which occurs around our northern coasts : " Being kept in a jar of salt water with small Crustacea, they devoured these animals, so much more highly organized than themselves, voraciously, apparently enjoying the destruction of the un- fortunate members of the upper classes with a truly democratic relish. One of them even attacked and commenced the swal- lowing of a Lizzia octopunctata, quite as good a Medusa as itself. An animal which can pout out its mouth twice the length of its body, and stretch its stomach to corresponding dimensions, must indeed be a 'triton among the minnows,' and a very terrific one too. Yet is this ferocious creature one of the most delicate and graceful inhabitants of the ocean a very model of tenderness and elegance." In worthy Philemon Holland's version of Pliny, there is a passage descriptive of the predaceous habits of the Jelly-fish, which has about it an air of such exquisite drollery that we can hardly help suspecting the dear old fabulist was purposely caricaturing what he professes' to describe : " I verily, for my part, am of opinion," says he, "that those which properly are neither beasts nor plants, but of a third nature between or com- pounded of both (the sea-nettles, I mean, and sponges), haue yet a kinde of sense with them. As for those Nettles, there be of them that in the night raunge too and fro, and likewise change their colour. Leaues they carry of a fieshie substance, and of flesh they feed. Their qualitie is to raise an itching smart, like for all the world to the weed on the land so called. His manner is, when he would prey, to gather in his body as close, streight, and stiffe as possibly may be. He spieth not so soon a silly little fish swimming before him, but he spraideth and displaieth those leaues of his, like wings ; with them he claspeth the poore fish, and so deuoures it. At other times he lies as if he had no life at all in him, suffering himselfe to be tossed and cast too and fro among the weeds, with the wanes of the sea : and look what fish soeuer he toucheth as he is thus floting, hee sets a smart itch vpon them, and whiles they stratch and rub themselues against the rockcs for this itch, hee sets vpon them and eates them. In the night season he lieth. for sea-vrchins and scalops." It is amongst the true " s tang-fish," of course those, that 32 A BATHING COMPANION. is, which possess the power of stinging that we meet \vith the most formidable animals the class includes. Only a com- paratively small number of the Jelly-fish apparently are en- dowed with this property, although there is good reason to be- lieve that these much-dreaded species are widely spread. The poisonous fluid with which they are armed is so powerful in its effects, as speedily to deprive the prey of every means of escape, torpifying all its faculties, and causing it to lie paralyzed and motionless, completely at the mercy of its destroyer. The long trailing tentacles of some species are endowed with this veno- mous property equally with the body itself, and form a most efficient set of organs for the capture of prey. No, sooner, indeed, does some luckless fish but come in contact with one of these delicate appendages, than it is immediately arrested in its movements, and made to writhe with agony ; the other tenta- cles meanwhile coil and twist around it, emitting.the pungent fluid at each fresh point of contact, and speedily reducing the victim to a state of perfect quiescence, when the tentacles slowly contract, and bring the prize within reach of the mouth. It must be obvious that animals of this sort are best known by man himself at a respectful distance. The reader may judge what kind of companions they make at close quarters from the following notice of one of them by Professor Forbes : " The Cyancea capUlata of our seas is a most formidable creature, and the terror of tender-skinned bathers. With its broad, tawny, fes- tooned, and scolloped disc, often a full foot and more across, it flaps its way through the yielding waters, and drags after it a long train of ribbon-like arms, and seemingly interminable tails, marking its course when its body is far away from us. Once tangled in its trailing ' hair,' the unfortunate who has recklessly ventured across the graceful monster's path too soon writhes in prickly torture. Every struggle binds the poisonous threads more closely around his body, and then there is no escape ; for when the winder of the fatal net finds his course impeded by the terrified human wrestling in its coils, he, seeking no contest with the mightier biped, casts loose his envenomed arms, and swims away. The amputated weapons, severed from their parent body, vent vengeance on the cause of their destruction, and sting as fiercely as if their original proprietor itself gave the word of attack." DIVERSITY OF FORM. 33 The organs concerned in inflicting this " prickly torture," are threads of extreme tenuity, which are coiled up iu minute capsules that occur in great abundance in the tentacles of the Jelly-fish and in various parts of the body. The slightest pres- sure causes the capsules to burst, when the liberated threads shoot out with amazing rapidity and force, piercing the object of attack, and conveying into the wounds they inflict some subtle poisonous fluid with which the animals are supposed to be armed. Most of the Jelly-fish which commonly frequent our own coasts belong to the Medusce, which may be regarded as the most typical division of the class. The animals belonging to it are distinguished, for the most part, by the possession of an. ambrella-shaped disc, by the alternate expansion and contrac- cion of which they propel themselves through the water. From the trivial circumstance that these movements of the disc have a resemblance to the heaving of the chest in respiration, the Medusa} have received the name of pulmonigrades, or lung- movers. It is only in calm weather, however, that the feeble strokes of the disc avail the Medusa? for the purpose of locomo- tion : during the prevalence of high winds the animals either descend to the tranquil depths, or, remaining near the surface, are driven helplessly along, and not unfrequently are cast in myriads upon the shore. A considerable diversity of form obtains amongst the Medusse, notwithstanding their general points of resemblance. Mr. Gosse compares them to the glass-shades of the gas-lights which show so conspicuously in the shop windows on a winter evening ; and, so far as it goes, the comparison is a good one, only it does not convey an adequate idea of the great variety of shapes which the Medusae assume. In some species the disc is only slightly convex, and the animal, when seen floating calmly in the water, has the appearance of a mere circular patch of jelly. In others, again, the disc rises proudly in the shape of a beautiful translu- cent dome, or assumes something approaching to the elegant pointed form of the Turkish minaret, while various leaf-like processes hang from the interior, and long thread-like filaments stream from numerous points around the circumference. Many of the smaller species are like thimbles, both in size and form ; while others have the appearance of beads or berries, except T) 3-i NAKED-EYED MEDUSA. that neither bead nor beny was ever seen of such perfect grace and beauty as these tiny Jelly-fish display. In size the Medusa* differ from one another still more than in form, the group includ- ing the largest as well as the most minute of all the Jelly-fish. A huge creature (Illiizostoma Cuvieri), which is occasionally thrown upon our own shores, measures three or four feet in diameter ; and in the warmer seas, individuals of this size are by no means uncommon. Then, at the other extremity of the scale, there are species so minute as to be truly microscopic, and which swarm in the ocean to an extent perfectly inconceivable. The Medusae are separated into two groups or divisions, dis- tinguished from each other by the presence or absence of certain delicate membranes or hoods, which in some of the species are found covering the eye-like spots, already referred to, around the margin of the body. No one has so carefully investigated the structure and habits of the naked-eyed Medusa) as the late Professor Edward Forbes, and, in the splendid work from which we have already quoted, he has given us an elaborate and philo- sophical, though no less popular, account of the British species of this division of the Jelly-fish. Some day, perhaps, a second Edward Forbes may arise to give the world a monograph of the covered-eyed Medusas ; but for the present that work is a desidera- tum, and our knowledge of the animals is somewhat meagre and obscure. One of the members of this group is that unwelcome visitor to bathing-places, whose unamiable qualities have already been referred to ; another is the Medusa aurita, the common Jelly- fish of our coasts, about whose early history we shall have a strange story to tell by-and-by ; and a third is the beautiful Chrysaora hyoscetta, a species by no means uncommon around the southern coast, and one which, with its delicate amber tints, and its long trailing tentacles and elegant furbelowed arms, arrests the atten- tion and excites the admiration of the most incurious of sea- side visitors. The naked-eyed Medusas also comprise some very beautiful forms. Few of the species are of large size, and some are ex- tremely small. One little fellow, Oceania ylobitlosu, is not larger than a pea, and, seen in its native element, a very pretty pea it makes. Another of these tiny Jelly-fish is Turris neglecta, not uncommon in the Solent and around the Isle of Wight, and which, sporting in the water, is " brilliant as a bud of A RAPACIOUS LITTLE DEMOCRAT. 35 brightest coral." The rapacious little democrat before alluded to, Sarsia tubulosa, is also one of the naked-eyed fraternity, and is not without its beauty. But the very pink of perfection in that line is a little fellow, Modeeria formosa, found around the Hebrides, and which, though scarcely larger than a split pea, ap- pears to have gone a great way towards turning the head of the worthy Professor who chronicles its discovery. It is, without question, a beautiful creature ; but whether its beauty is best indicated by saying that " it is gorgeous enough to be the diadem of the smallest of sea-fairies, and sufficiently graceful to be the nightcap of the tiniest and prettiest of mermaids," may admit of a doubt ; although assuredly the enthusiastic Professor may be allowed to describe his own discoveries in his own style. One of the commonest and most characteristic of the Jelly-fish of the next section those, namely, which make their way in the world by means of cilia, and are hence known as ciliogrades~ is the Cydippe pileus, a gay and active little creature, and a great favourite with naturalists, who have appropriately named it after one of the sea-nymphs of old. It is impossible to watch this graceful little rover without being struck with admiration at the vivacity and sprightliness of its movements. Of a glo- bular, but slightly elongated form, and about the size of a large bead, the Cydippe dances gaily through the water, its delicate gelatinous body, faintly blue in colour, glistening in the sun, while the rapid play of its cilia scatters the rays of light in lovely rainbow tints about its path. The apparatus by means of which the Cydippe thus speeds its way along, circled with glory, consists of rows of minute cilia, arranged side by side, in the form of broad flat plates, upon eight firm bands, which run from pole to pole of its body, like the meridian lines of a globe. Each of these bands, with its thirty or forty rows of cilia, one above the other, has an appearance something like that of the paddle-wheel of a steam-boat ; but, unlike what is seen in that cumbrous contrivance of man, locomotion is effected, not by the revolution of the wheel, but by the separate motion of each of the paddles. Every one of these delicate organs is endowed, in fact, with the property of separate and independent motion, and over the whole of them the little Jelly-fish has the most complete control. It can retard or stop their movements at pleasure, and by arresting the play of one or more rows, 36 THE GAY CYDIPPE. whilst the remainder continue in rapid vibration, it is enabled instantly to change the direction of its course, and to wander through the waves at will. Nor is this all. In addition to its belts of paddles, the Cydippe is furnished with two long tendril-like appendages beset with deli- cate filaments, which issue, at the lower part of its body, from two deep cavities, into which they can be completely withdrawn with great rapidity. Sometimes the little fellow may be seen joyously glancing about in the water with both these organs entirely concealed from view, but only a few moments probably elapse before they are shot out to four or five times the length of the body, and while the delicate processes along their course uncoil and twirl about, the tendrils themselves are flung into an endless variety of beautiful curves, with an air of elegance and grace perfectly indescribable. Not the least curious circumstance connected with this inte- resting Jelly-fish, is its odd and very original method of procuring food. It might be thought that with no eyes to see, and no special organs for the capture of prey, it would be hard put to it to obtain a living. But, no ! It seems to have not the slightest care or concern about the matter, and manages to secure a plentiful supply of provender almost without an effort, and when apparently it is intent upon gaiety and pleasure alone. The fact is, the cavity which forms the Cydippe's stomach perforates its body almost from pole to pole, while the orifice at the lower extremity can be opened or shut at pleasure. All the little fellow has to do, therefore, when in want of food, is to incline its body forward, and keep its mouth wide open the while it dances through the water, by which means a continuous stream of the fluid is caused to pass into the stomach, hurrying along with it, of course, whatever spoil it may chance to contain. In this most convenient manner, the tiny shrimps and other Crustaceans upon which the Cydippe feeds are brought within its power, the mouth closing, of course, the moment a prize enters, and securing it as in a living trap. It appears from the observations of Mr. Patterson that these " Gay creatures of the element, That in the colours of the rainbow live," are endowed with a tenacity of life somewhat remarkable for GIRDLE OF VENUS. 37 animate of their class. On one occasion this gentleman cut up a Cydippe, that had been cast ashore in a shattered condition, into portions so minute that one piece of skin had but two cilia re- maining attached to it, yet the vibration of these organs continued for nearly a couple of days afterwards. On another occasion he tells us, a Medusa, about as large over as a sixpence, caught hold of a Cydippe confined in the same glass with it, and when at length the little creature had regained its liberty, it was found that the Medusa had cut away a piece fully equal to a sixth of the entire bulk of the body ; yet the Cydippe seemed quite un- conscious of the mutilation, and evinced no diminution of its activity or its enjoyment ! The same writer states that he once placed some specimens of a species somewhat larger than the little Cydippe of which we have been speaking, in a glass-jar on the chimney-piece, and that their bodies were so transparent that the blossoms of some flowers, which were also there, were distinctly seen through them. " It was impossible," adds Mr. Patterson, " to look upon these bright-tinted blossoms of earth, and on those colourless, yet not less delicate children of ocean, and not feel that loth must have enjoyed the guardianship of Him from whom all their loveliness was derived ; that He who had for ages preserved the flowers from perishing by frost, or wind, or rain, had likewise saved the Beroe's from destruction amid the wild tempest of the ocean." Another example of the Ciliograde Jelly-fish is the rare and beau- tiful CestumVeneris, or Girdle of Venus, a resplendent creature resembling a long flat ribbon of translucent glass, some five or six feet in length, by about as many inches in width. The habits of this remarkable animal are but little known, although its affinity to the present group of Jelly-fish is clearly ascertained. Its body is of a delicate gelatinous consistence throughout, and is fringed at the margins with a double row of countless cilia, which, as in the case of the Cydippe, produce when in motion a succession of the most brilliant colours. At night the Cestum is said to glow in the watery depths with peculiar splendour, and to resemble, as it winds its way along, an undulating belt of flame. In the Jelly-fish of the next section we meet with a peculiarity of structure entirely new. The group is but a small one, and all 38 A SHIPWRECKED FLEET. the animals belonging to it are distinguished by the possession of a delicate cartilaginous plate, which forms a sort of skeleton or sxipport to the soft gelatinous body. In the majority of this order the body is an oval or circular disc, and has depending from its under surface numerous appendages, termed cirri, by which the animals move through the water, whence the entire order has received the name of Cirrigrades. A far more inte- resting and effective apparatus for locomotion is found, however, in some of these Jelly-fish, in the shape of a thin membrane or sail, which rising from the upper surface of the body, and sup- ported by a sort of mast, is acted on by the wind, and drives the little voyager along, a very "ocean Mab " and " fairy of the sea." Large fleets of these elegant creatures are sometimes met with in the wanner latitudes, gaily scudding before the gentle breeze, in compact order, and presenting a spectacle of singular interest and beauty. One of the commonest of these sail-bearing Jelly-fish, and one which, during the prevalence of high winds, is occasionally thrown upon our own shores, is the Velella lata, in which the disc is of a fine blue colour, and has the cartilaginous plate in the form of a dorsal shield, with the delicate sail-membrane rising obliquely from its centre. The sail is set to the dorsal shield, much in the same fashion as the lateen sail of the Malay boat to the deck, and hence the Velella commonly passes amongst sailors as the " Sallee-man." A drawing of this attractive little creature has been made by Professor Allman from the living Jelly-fish, "which sat, or rather floated, for his likeness," says the worthy Professor, and " was one of a fleet of countless multitudes which, in the autumn of 1836, was driven upon the coast of the county of Cork. On the subsidence of the gale, which had been blowing strongly from the south-west, the coast for miles roun\ was strewn with the remains of the shipwrecked fleet." In another division of the Jelly-fish, the crest dr sail is furnished with muscular bands by means of which it can be raised or lowered at pleasure a circumstance which has procured for the entire group the very appropriate designation of " bargemen." One of the number is a curious little fellow, which, by the lofty rounded form of its body, has earned for itself the appellation tnitrata (mitred), although, if it have any ecclesiastical leanings at all in the matter of shape, it approaches most nearly, perhaps, PORTUGUESE MAN-OF-WAR. 39 to that of the odd-looking crimson skull-cap of his Eminence the Cardinal. All the Jelly-fish of this division have the stomach in the form of an inverted flask, hanging from the under surface of the body, with the mouth at its lower extremity. The cirri immediately surrounding the mouth are adapted rather for prehension than locomotion, and while some of the members are busily employed in seizing the minute prey, others are engaged in holding small shells and stones, the ballast necessary to trim the little vessel as it calmly sails along the surface of the deep. The fourth and last section of the Jelly-fish includes the animals which Cuvier termed Hydrostatic acalephce. According to the classification now adopted, they constitute the order Physo- grada, so named from the inflated air-bags with which they are provided, and by means of which, in part at least, they effect locomotion. In this section of the Jelly-fish we entirely lose the circular radiate structure, by which the previous orders are dis- tinguished, and have, instead, a sort of lateral symmetry or corre- spondence between the two sides of the animals composing it. A well-known member of this division is the Physalia pelagica, or Portuguese-man-of-war of sailors. The body of this singular Jelly-fish consists of a large pear-shaped air-bladder, beautifully tinted with blue, green, and crimson. It is surmounted by a fringed crest or sail of the richest purple, and has depending from it a cluster of variously-shaped tentacles, some of great length, and employed in the capture of prey ; others short, tubular, and terminated by suckers through which the Physalia, destitute of a true mouth, imbibes its food. This food consists, it is said, principally of small fish ; and the long tentacles by which they are caught are truly formidable implements. According to Dr. Cr. Bennett, they can be coiled up within half an inch of the air-bag, and then suddenly shot out to the length of twelve or eighteen feet, twining round and round the body of the prey, paralyzing it by means of their acrid secretion, and then con- tracting so as to bring it within reach of the tubular suckers. On one occasion Dr. Bennett captured some specimens of the Pliysalia, which had several small fish entangled in their ten- tacles ; and by placing them immediately in a large vessel of sea- \vater, the process of feeding by absorption was distinctly observed. The tubular suckers were soon seen to be filled with 40 DOUSING THE SAILS. portions of the fish, which imparted to the almost transparent coats of the suckers a distinct silvery hue, as though they had been injected with mercury. Dr. Bennett made several careful dissections to ascertain whether these tubular suckers terminated in any common receptacle, or organ at all analogous to a stomach, but no trace of anything of the sort could be found ; so that there can be no doubt that these suckers form the Physalia's only digestive apparatus. With a view to ascertain whether there was any truth in the current opinion as to the stinging powers of the Physalia, Dr. Bennett once seized hold of a specimen by the distended bladder ; but he paid a heavy penalty for his daring. The animal at once drew up its long slender filaments, and, entwining them about the hand and fingers which held it, inflicted severe and pungent pain ; adhering, at the same time, so tenaciously, that it was only with great difficulty they could be torn off piece by piece. The pain, moreover, extended upwards along the arm, and continued to be felt throughout the day. As in the case of the Veldla, vast shoals of the Physalia are often encountered in the tropic seas, where the surface of the ocean is frequently crowded with their bright and glittering forms over an area of considerable extent. Mr. Gosse, in his " Letters from Alabama," has an interesting account of an immense fleet of this interesting Jelly-fish, which he encountered at the entrance to the Gulf of Mexico. They were of all sizes, from an inch to a foot or more in length ; and they studded the smooth surface of the sea as far as the eye could reach ; the vessel, indeed, was nearly a whole day in getting clear of them. It often happens that in passing just under the lee of a vessel, the sudden lull, caused by the interposition of the ship between it and the wind, causes it for a moment to lie flat on the water, instantly afterwards re- suming its upright position. The English Jack-tar, it seems, takes this " dousing its sails," on the part of the " foreigner," as a fitting act of homage to the British flag. It is commonly said, that should danger threaten the Physalia while thus wafted along on the bosom of the deep, it can at once contract its sail, expel a portion of the contents of the air-bladder, and descend in security to the depths below. But this seems to be a mistake. All who have examined the animal in a living state concur in the statement that it has no apparent means of discharging the con- COMPOUND FORMS. 41 tents of the air-bladder ; nor is it possible, even by the applica- tion of pressure, to force out the contents, excepting by bursting the bladder itself, and producing an explosion. And that the animal has not the power of descending in the water, at pleasure, seems to be proved by the fact that numbers of them are some- times found on the shore, thrown up by the violence of the wayes. Professor Owen mentions that he has seen a whole fleet of them wrecked on the coast of Cornwall, to which iron-bound region they had been buoyed by their air-bladders. Naturalists have been sadly puzzled what to make of another section of these animals, known as the Diphydce, or Jelly-fish of a double form. They are diminutive little creatures, and com- posed of two pieces which easily separate, and when detached, will swim about independently for hours together. Hence arose the difficulty whether to regard these compound bodies as two animals united into one, or as one animal which, for a time, might be separated into two. Cuvier, and most zoologists following him, adopted the former opinion, regarding the two pieces as two independent animals. It has lately been very satisfactorily shown, however, that the two pieces do, after all, constitute but one animal, although our knowledge of these sin- gular creatures is still very incomplete. Considerable diversity of form prevails amongst them, and frequently, also, between the two portions of the same animal. They are so beautifully transparent as to be almost invisible in the water, and occur chiefly at great distances from the shore in the seas of warm climates, where they abound in great profusion. Nothing connected with the Jelly-fish more truly deserves to be characterized as wonderful than what has of late years been discovered with respect to their mode of reproduction. Two distinct modes of increase have been ascertained to prevail amongst these animals one by the development of eggs, the other by the process of budding, or gemmation. According to the latter mode, which was first observed by Sars, a Swedish naturalist and clergyman, the young Jelly-fish sprout from the bodies of their parents like the leaf-buds of a plant, and after attaining to a certain stage of advancement, become detached, and swim away, to enjoy a free and independent existence. The singularity of this mode of increase is apt to be under rated, because of the insignificance of the creatures amongst 42 G1OIMATTON-. which it obtains. But Professor Forbes, in his elaborate work before quoted from, helps us to estimate the oddity of the process, by supposing it to be observed amongst animals somewhat more bulky, and higher in the scale than Jelly-fish. " Fancy," he says, " an elephant with a number of little elephants sprouting frorr* his shoulders and thighs, bunches of tusked monsters hang- ing, epaulette-fashion, from his flanks, in every stage of advance- ment. Here a young Pachyderm, almost amorphous ; there one more advanced, but all ears and eyes ; on the right shoulder a youthful Chuney, with head, trunk, toes, no legs, and a shape- less body ; on the left, an infant, better grown, and struggling to get away, but his tail not sufficiently organized as yet to per- mit of liberty and free action ! The comparison seems grotesque and absurd, but it really expresses what we have been describing r.? actually occurring among our naked-eyed Medusse. It is true that the latter are minute, but wonders are not the less wonderful for being packed into small compass." No less than four species of Jelly-fish found around our own shores have been observed to reproduce their kind in this manner ; one of the number being the graceful little Sarsia gemmifera, in which the young brood may be seen sprouting from the sto- machal peduncle of the parent. It is to the development of the ova of the Jelly-fish, however, that the chief interest pertains, the germs being now ascertained to pass through a series of the most remarkable transformations before assuming their mature form. The extraordinary history which follows is that of the common Jelly-fish of our own coast (Medusa aurita) which every visitor to the sea-shore must have often seen, and will at once recognize by the four pinkish rings in the centre of its almost colourless disc. The eggs of this species are produced within the body of the Jelly-fish in regular ovaries the rings above mentioned whence they are transferred to a number of curious pear-shaped sacks, which are developed from the under surface of the arms which surround the mouth. Here they are retained for a time, and then, the sacks bursting, the embryos escape in the form of minute oval bodies, covered with cilia, and, to all appearance, a swarm of infusorial animalcules. In this state the young brood remains for some days, sporting gaily in the water, and subsisting apparently in just the same manner as the creatures they SQ DKVELOPHENT. 43 closely resemble. In due course, however, one end of the germ begins to contract, and gradually is developed into a sucker-like base, whereupon each of the little creatures attaches itself to some fixed object, and becomes for a while settled and stationary. And now a new character is assumed. The cilia, no longer needed, disappear. A cavity is formed at the upper extremity of the body, and, gradually deepening and enlarging, it becomes at length a capacious mouth ; around this four arms sprout forth, which being soon succeeded by four more, and these by another four, we have at length from the egg of a Jelly-fish an animal, which is to all appearance an ordinary hydra-form Polyp ! Nor is it in form alone that the correspondence holds : the disguised Jelly-fish actively discharges all the functions of Polyp life, twirling its arms about to entrap prey, gorging the prey it secures, and ejecting the indigestible parts of its foed through the mouth, precisely as is done by the Hydra itself. It has, more- over, all the Hydra's power of renewing lost parts, and repro- ducing the entire body from a single portion ; and, lastly, it multiplies itself, as do the true Polyps, by buds or gemmules, KO as often to produce a whole colony of similar beings ; add to all which, that the creature has been known to remain in the Polyp state for nearly two years, and no one can wonder that it should often have been mistaken for an animal in its mature form, without the remotest suspicion of its true character. After the lapse of a considerable interval, however, important changes take place, and the extraordinary nature of the seeming Polyp gradually becomes apparent. The body lengthens ; its skin begins to shrivel ; ring-like depressions appear around it ; and in a little while the entire Polyp seems as if cut into a number of horizontal sections or slices, which turn up at the ed;j.es, and present the appearance of a pile of watch-glasses standing one within the other. Tentacles now grow out from each of the upturned edges, and the several sections become less and less firmly attached to each other. In one or two days more, the connection between the different sections altogether ceases, and one by one, beginning at the top, they swim off, and become a brood of young Jelly-fish ! It is upon these remarkable facts, and others of a like cha- racter, observed in the reproduction of some of the compound zoophytes, that Steenstrup, a Danish naturalist, has founded his 44 ALTERNATION OF GENERATIONS. novel doctrine of " Alternation of Generations." According to this doctrine or hypothesis, the successive stages of advancement through which certain of the lower forms of life pass, are to be regarded, not as different phases of a process of metamorphosis or transformation, like that of the caterpillar into a butterfly, or the tadpole into a frog, but as distinct generations, in which the parent animal produces an offspring totally unlike itself, but which begets a progeny that returns in form and nature to that of the original stock ; so that, as the originator of the idea himself puts it, the maternal animal does not meet with its resemblance in its own brood, but in its descendants of the second, third, or fourth degree of generation. The question which this hypothesis opens up is a much larger one than can be properly discussed here ; nor is it possible, perhaps, in the present state of our knowledge, satisfactorily to explain all the facts which relate to it. It must be borne in mind, however, that the facts themselves are already fully established, and that whatever interpretation may be put upon them, they must undoubtedly be ranked amongst the most wonderful phenomena which recent investigations in natural history have brought to light. Reference has already been made to the luminosity of some of the Jelly-fish. There is reason to believe that all these animals are endowed with the property of emitting light ; and it is mainly to their agency that we owe the beautiful phenomenon known as " the phosphorescence of the sea." " When on a sum- mer's evening," says a writer before quoted, " the waves flash fire as they break upon the shore, or glow with myriads of sparks us they curl and froth around the prow of the moving ship, or under the blade of the striking oar, it is to delicate and almost invisible Medusa? that they chiefly owe their phophorescence." It has never been clearly ascertained what organs are concerned in the production of this phosphoric light, nor has the most careful examination ever availed to detect the secretion itself, al- though there can be but little doubt that the animals are enabled to exhibit the phenomenon at will. In many of the species, the phosphorescence may be evoked when the animals are kept in confinement. " On being touched or otherwise irritated," says Mr. Gosse, " they suddenly become illuminated, the light ap- pearing in rings or circles of luminous points, which alternately LUMINOSITY. 4u flash and die like gas-jets on a festive gala night." The pheno- menon is most frequently witnessed when the surface of the sea is ruffled by some gentle breeze, dead calms and very rough weather being alike unfavourable to its production. It is well described, as seen around our own shores, by Sir "Walter Scott in his " Lord of the Isles :" " Awaked before the rushing prow, The mimic fires of ocean glow, Those lightnings of the wave ; Wild sparkles crest the broken tides, And, flashing round the vessel's sides, With elfish lustre lave, While far behind, their livid light To the dark billows of the night A gloomy splendour gave." Over all parts of the ocean alike the waves are lit up at times with these animated fires ; but in the warmer latitudes the spectacle assumes an aspect of extraordinary sublimity and splen- dour. " Between the tropics," says Humboldt, " the ocean simul- taneously develops light over a space of many thousand square miles. Here the magical effect of light is owing to the forces of organic nature. Foaming with light, the eddying waves flash in phosphorescent sparks over the wide expanse of waters, where every scintillation is the vital manifestation of an invisible animal world/ According to the enthusiastic accounts of voy- agers, the appearance of the ocean on these occasions is grand and beautiful as it is possible to conceive. Far as the eye can reach, the crest of every wave, which during the day is white with foam, becomes transformed by darkness into a swelling ridge of light, while here and there, where the billows dash with greater violence, the spray flies up, sparkling and glittering like a shower of stars, and falling again, is lost in a sea of effulgence. Occasionally, too, while the more minute forms of the Acalepha? produce this diffused luminosity at the surface of the ocean, the larger kinds are seen below, illuminating its m) r stic depths some gleaming through the water with a pale and steady light, like submerged moons, others glowing with dazzling brightness, like balls of molten metal, or shooting by like the fiery meteors of the heavens above. CHAPTER III. INSECTS, AND THEIR HUNTEBS. " Is not the earth With various living creatures, and the air Replenished, and all these at thy command To come and play before thee? Know'st thou not Their language and their ways? They also know And reason not contemptibly ; with these Find pastime." THE readers of the " Tatler" will remember that in one of the famous lucubrations of Isaac Bickevstaff, Esq., the study of the insect tribes is held up to ridicule in the person of a certain virtuoso, one Nicholas Gimcrack, who having spent a large fortune in making a collection of insects and other "natural rarities and curiosities," at his death bequeaths the accumulated treasures to his family and friends. In his lifetime the " whimsical philosopher " is made out to have set a greater value on a collection of spiders than on a flock of sheep, and to have sold his coat off his back to purchase a tarantula ; while in the details of the will, which is given entire, the satire is carried to its height by the absurd gravity with which the poor enthusiast is represented as distributing his trifles in the imme- diate prospect of death. It was thus that the wits, in days gone by, made merry with the poor savants who gave their attention to the insect world ; and though many and marvellous changes have taken place since the time when the " Tatler " and the " Guardian " made their appearance, damp from the printing-office, on the breakfast- tables of our forefathers, there has been but little change in the popular estimate of the dignity or advantage of entomological pursuits. The opinion of most men is still pretty much what Addison gives us as his judgment on the subject, that " obser- vations of this kind are apt to alienate us too much from tho knowledge of the world, aiid to make us serious upon trifles ;" a 48 PENALTIES OF ENTOMOLOGY. result, he goes on to say, which "exposes philosophy to the ridicule of the witty, and the contempt of the ignorant." In one respect the entomologist is no doubt a much more tolerated character now than formerly. He may hoard up the treasures in his cork-lined cabinets with never so much care, and may even make away with a " considerable estate " in getting them together, and yet incur no risk of being exposed to public ridicule as another Nicholas Gimcrack. But this immunity is granted him only so long as he keeps his predilections to himself, without exposing them openly to the eye of the world. The man who would venture abroad, net in hand, in pursuit of his favourites, must still expect to be looked upon by the majority 'of mankind as a sort of lunatic at large, who is allowed to have his own way only because his whim is an innocent one, that does no harm to his neighbours. It is given to but few amongst us to bear with equanimity the pity or contempt of our fellow-creatures ; and it is not surprising that many persons have been deterred from the study of ento- mology by a fear of incurring the penalty attached to it. But, in spite of this drawback, the science has long had a devoted band of adherents, and within the last five or sive years their number has considerably increased. It would appear indeed that the study of the insect tribes is at length becoming extremely popular ; for the entomologists are fast growing to be an im- portant body, and now have not only an Annual of their own, but a small weekly newspaper, the " Entomologists' Intelligencer," which is conducted with much spirit, and regularly chronicles all the noteworthy observations and doings of the body. This result is in great part, no doubt, attributable to the republication, in a cheap and compact form, of the famous " In- troduction to Entomology," by Kirby and Spence, a book which, for now nearly half a century, has been a standard authority on the. subject. It is almost impossible to read this engaging volume without becoming enamoured of the study of the little creatures whose habits and instincts it details ; and the rapidity with which the new edition has been sown broadcast over the land may reasonably be expected to produce before long an abundant crop of incipient entomologists. But it is not young people merely who are taken captive by the book ; we have lately met with two instances in which it has exerted a similar INTEREST OF THE SCIENCE. 49 influence over persons in advanced life, and devoted to pursuits which it would be supposed were little calculated to leave room for any enthusiasm on behalf of insects. la one case an erudite black-letter friend of ours, who has recently been exploring, and with good results, among the Syriac MSS. of the British Museum, was so delighted with the book, on dipping into a copy which accidentally fell in his way, that he straightway pur- chased one for himself, read it with avidity, and has since be- come a most attentive student of insect life. The other instance was that of one of our most popular metropolitan clergymen, who, having had occasion to refer to the book for the elucidation of some passage of Scripture relating to insects, was so deeply interested in what he read, that he publicly recom- mended the work from the pulpit, with a warmth of commenda- tion which somewhat surprised his hearers. The truth is, that, to a person who has never before given attention to the subject, the reading of Kirby and Spence opens the eyes to a new world of interest and beauty, which appears to be only the more won- derful from the circumstance that it has been so long unheeded. There can be no doubt that one of the great attractions of entomology lies in the fact, that it thus invests with an attri- bute of wonder the most common and familiar objects. The little creatures that have crossed our path a hundred times, and which we have before regarded merely as so many sources of injury or annoyance, all at once become transformed into objects of great interest, astonishing us by the variety and beauty of their structure, and, at the same time, exciting our admiration by the wonderful instincts with which they are endowed. It is a great advantage, moreover, in the study of this science, that the objects of investigation are everywhere accessible. No one need lack the opportunity of observing and studying the habits and history of some members of the insect tribes. Much may be done without stepping beyond one's own threshold ; and the possession of a garden, even though it be no bigger than the extraordinary six-feet-square enclosures so designated, which one sometimes sees attached to suburban Cockney cottages, opens up to investigation more wonders than most men would be able to explore in half a lifetime. Nor is it merely in verify- ing the observations of others that the beginner in the study may employ himself. There is no branch of natural history in E 50 THE MODEL INSECT. which there is more room still left for original research, or in which such research is more likely to conduce to the general advancement of the science. It has been said, indeed, that the field of entomology in Britain is already fully explored ; but no idea could be more erroneous. Not only are new tacts in the economy of insects already known continually being discovered, but every year is adding to our list of native species a considera- ble number of insects not previously recognized as indigenous to the British Islands. Before proceeding further, it may not be amiss to remind our readers that all are not insects which are insects called. The entomologist takes no heed of a number of little creatures which popular phraseology everywhere assigns to his care. The more precise and discriminating knowledge of the present day cuts off large sections of the animal world, which naturalists themselves, the great Linnteus included, formerly ranked with the insect tribes. The " Model" insect is an animal which, in its mature form, has a body separated into three distinct regions, six legs, two antennas or feelers, and one or else two pairs of wings. Let the reader make prisoner for a time of the first House L'ly that settles on his nose, and he will see that the gentleman corresponds to the description we have given. The Common Wasp, a Cockchafer, or a Butterfly, would answer the purpose equally well, and would also show how wide the range of variation may be, while still preserving the same general typical form. It is only in their mature or perfect state, how- ever, that insects exhibit these distinctive characteristics, and before that mature form is reached, they have, for the most part, to undergo a more or less complete series of transformations. Nothing in. the whole range of natural history excites the wonder of the observer more powerfully than these transforma- tions or metamorphoses of the insect tribes. " If," say Kirby and Spence in one of their most frequently-quoted passages, "a naturalist were to announce to the world the discovery of an animal which for the first five years of its life existed in the form of a serpent ; which then penetrating into the earth, and weaving a shroud of pure silk of the finest texture, contracted itself within this covering into a body without external mouths or limbs, and resembling, more than anything else, an Egyptian mummy ; and -which, lastly, after remaining in this state with- TRANSFORMATIONS. 51 out food and without motion for three years longer, should at the end of that period burst its silken cerements, struggle through its earthly covering, and start into day a winged bird, what, think you, would be the sensation excited by this strange piece of intelligence ?" What indeed ? And yet the supposed case differs but in matters of detail from the actual history of by far the larger proportion of the members of the insect world. In some of the tribes the metamorphosis is only partial, and the insects which belong to them exhibit pretty much the same appearance, and lead an almost identical mode of life throughout the entire period of their existence. Amongst other tribes, the Moths and Butterflies especially, the reverse of this obtains ; and no degree of familiarity with the subject is sufficient to destroy in the mind of a thoughtful person the feeling of wonder, and almost awe, to which the observation of the extraordinary changes which these creatures undergo gives rise. The interest of entomology as a study consists, to a great extent, in noting the endless variety of procedure amongst insects while preparing for, or actually undergoing, these transformations. The history of every individual insect, from the moment when the little cater- pillar or grub makes its escape from the egg, through each subsequent incident and stage in its career, till it finally comes forth from the pupa, a winged denizen of air, is replete with interest to the curious observer, and could hardly fail to impress a devout mind with the sentiment expressed by Bonnet : " It seems to me that I am at a spectacle where the Supreme Artist is hid behind the curtain." Much misapprehension prevails as to the precise character of these insect transformations. And strangely enough, an error which was not altogether unnatural when the general subject of the embryonic development of animals was less per- fectly understood than it is at present, is still propagated by some of the leaders in entomological science. The error to which we refer is thus stated by Kirby and Spence : " A caterpillar is not, in fact, a simple but a compound animal, con- taining within it the germ of the future Butterfly, enclosed in what will be the case of the pupa, which is itself included in three or four more skins, one over the other, that will succes- sively cover the larva." According to this notion, which is supported by several great names amongst the naturalists of 52 maoovcsrnom. former days, the metamorphosis of an insect is nothing more than.a repeated casting off of its external skin, the perfect insect existing all the while in its proper form, beneath and within its different external wrappers. Bat surely, as Professor Rymer Jones remarks, it can be no more necessary to suppose the pre- existence of so many skins in order to explain the monks of a caterpHar, and its subsequent changes to a chrysalis and a Butterfly, than to imagine that we ourselves have several skins oae beneath the other, because, when the cuticle is removed by the application of a buster, a new layer of epidermis is again and again renewed. The error arises from a mistaken ioea, that the metamorphosis of the insect is something singular and exceptional in the animal world, combined with a misconception as to the true nature of the epidermic investment. The proper explanation of the phenomena appears to be this, that the suc- cessive changes which the insect undergoes are, in principle, Hoe same as obtain amongst most other creatures in the earlier stages of their existence ; and that the repeated moults and changes of form are due to the living skin or cntis beneath the external epidermis gradually developing itself, and expanding into vari- ously-shaped organs, in accordance, in every case, with the law of being, if we may so speak, of each individual species. The popular notion is, no doubt, by far the most attractive of the two ; but, unfortunately, nature and truth do not always square with our ingenious fancies, which injure quite as often as they advance the cause of science. Let us pass, however, from this somewhat dry and abstruse topic to the history of an insect familiar to all our readers, and which has long occupied the attention of naturalists. The Aphidet, or plant lice, the " green fly " of the gardener, have as wonderful a history as any members of the insect tribes ; and with a small expenditure of trouble our readers may trace the entire wonderful history for themselves. It appears that, in autumn, the swarms of Aphides which infest our plants are composed of both male and female insects, which, after pairing, and the deposition of the eggs by the females for a fresh brood, speedily die. In the following spring, as soon as the sap begins to flow, the eggs which have survived the rigours of winter are hatched, and a brood of fully-formed young lice is produced, which beginning immediately to pump up sap from the tender leaves and REPRODUCTION EXTRAORDINARY. 53 shoots, rapidly increase in size, and soon come to maturity. In this state is it found that the whole brood, without a single exception, consists of females, or, let us say, of individuals capable of reproduc- ing their kind. In a short time these animals give birth directly, and without the deposition of eggs, to a second brood of females like themselves, which again produces a third brood in the same way, and of precisely the same description ; and this process goes on throughout the summer without the appearance of a single male insect. In the autumn, however, insects of both sexes are again produced, and the females deposit eggs, to continue the species in the same manner through the next summer. Tliis extraordinary mode of reproduction amongst the Aphides was first made known by Bonnet, who traced the development of nine successive generations of the asexual forms. In the same way Duvau subsequently followed the course of eleven genera- tions ; whilst Kyber, by keeping a colony of the insects in a warm room, continued this process of virgin reproduction for no less than four years. It is no wonder that circumstances so truly remarkable should have excited great attention amongst naturalists, or that various theories should have been advanced to account for it. Reaumur indeed endeavoured to elude the difficulty altogether by assert- ing that Aphides were androgynous ; while Leon Dufour referred the phenomena to spontaneous or equivocal generation. The true explanation in all probability is that suggested by Steen- strup, who gives the reproductive virgins the curious name of ammen, or wet-nurses, and treats the matter as a case of " alterna- tion of generations." It is quite clear, however, that much has yet to be done before the matter can be regarded as settled, and any enterprising entomologist may, if he will, turn to good account the little vermin which batten on his geraniums and calceolarias, by still farther following up the subject. Closely connected, and in many respects, no doubt, identical, with this anomalous mode of reproduction among the Aphides, is the phenomenon which has been designated parthenogenesis, or re- production by virgins, which are indisputably true females. Pro- fessor Siebold, of Berlin, has greatly added to our knowledge of the insect wonders of this kind by his essay " Ou a True Parthe- nogenesis in Moths and Bees," a work which has been given to the English public in a translation by Mr. Dallas, one of our 54 CLASSIFICATION OF INSECTS. ablest entomologists, and in which this extraordinary mode of reproduction is shown to obtain amongst the Silk-worm Moth, and some others ; and also amongst the Honey-Bees. In the classification of insects, the wings, which are the grand and characteristic endowment of the tribe, serve as the basis for their distribution into separate orders. It is not necessary here to go into the details of the classifications generally adopted, though it will not be out of place to mention briefly some of the more pro- minent divisions. The Moths and the Butterflies constitute the order Lepidoptera, or scale- winged insects ; the so-called down or feathers with which the wings of these insects are clothed being nothing less than an almost infinite number of beautiful sym- metrically-formed scales, attached to the membrane of the wing in regular rows, like the slates or tiles covering the roof of a house. " The shard-borne beetle " and his allies form the Co- leoptera, or sheath- winged order ; the said " shards," in all their endless variety, being literally the sheaths or shields under which the real organs of flight are neatly folded up when not on " active service." Bees, Wasps, Ichneumon-flies, and the like, have simple membranous wings, and are therefore the Hymen- optera ; the Dragon-fly with its gauzy wings, the frail Ephe- mera and others of the kind, form the Ncuroptera, or nerve- winged order ; and so on the number, nature, or degree of development of the organs of flight being the guide throughout for the arrangement of the mighty host of animated forms which constitute what is fitly termed " the insect world." One of the few insects which do not readily fall into rank and file in the ordinary systems of classification is that little rogue often very well known where his acquaintance is never acknow- ledged, the Common Flea. Pulex irritans is his name, and very irritating fellows they are generally allowed to be ; though that genial old lady, mentioned by Kirby and Spence, who thought them " the prettiest little merry things in the world,"' appears to have regarded them with great favour. It has often occurred to us, by the way, that the old lady in question must be the same that is referred to in another part of the " Introduction," who declared she could always hear when a Flea walked over her nightcap, and that it clicked as it went along, as if walking on pattens ! If we may credit the statement of a very respectable matron of our ac- quaintance, the extraordinary summer of 1857 called forth these AN IMPERIAL FLEA. 55 little |- ests in great abundance, and rendered it a difficult matter to dislodge them from their quarters. Any one again afflicted in this manner would do well to remember the advice given by old Tusser in Lis " Points of Goode Husbandry :" " While wormwood hath seed, get a handfull or twainc To save against March, to make flea to refraine: Where chamber is sweeped, and wormwood is strown, No flea for his life dare abide to be known." But if that remedy should not suffice, it would not be amis-, perhaps, to catch a few of the ringleaders, and make an example of them, by plying then with round shot, in the way Christina, Queen of Sweden, is said to have done with the Lilliputian piece of ordnance still exhibited to the curious in the arsenal of Stockholm. Not long since, at one of the meetings of the Entomological Society, Mr, Westwood exhibited what was described as a new species of Flea, of monstrous size, which had just previously been found in a bed at Gateshead. The name proposed for the monster was Pulex imperator, a style and title the perfect pro- priety of which was xinquestionable for a monster twenty times larger than the Common Flea ! It did not appear whether the stranger was a nondescript species imported from abroad, or a na- tive Briton then first brought to light. In either case the prospect was not an agreeable one. The common Bed-Bug was a stranger amongst us once, though in many of our London lodging-houses we will of course assume that it is never seen elsewhere it is now very literally a " terror by night ;" and who was to say that this imperial blood-sucker might not get a footing amongst us ? Fortunately we need be under no anxiety : a few months after the discovery was first announced, Sir. Westwood again brought his gigantic Flea before the Entomological Society : this time, however, it was for the purpose of explaining that Pulex imperator turned out to be no Flea at all, but the mutilated body of a young Cockroach ! The origin of the mistake was satisfactorily accounted for, and the Imperial Flea was erased from the list of British insects a great loss to science, no doubt, but one which, domestically speaking, we can bear very com- placently. If there be any one insect which more than another deserves 56 THE HONEY-BEE. to be called the universal favourite, it is surely the Honey-Bee. Little children sing about it in the nursery ; it is an everlasting theme with those grown-up children the poets ; and the philo- sophers find in it abundant scope for their profoundest study. It ranges at large over the new world as well as the old, every- where known, and everywhere an object of interest, and even affection. " A bee among the flowers in spring," says Paley, " is one of the cheerfullest objects that can be looked upon. Its life appears to be all enjoyment ; so busy and so pleased." And what a picture there is in that line of Keats' " A May busli with the bees about it ;" and in that other exquisite touch, humming the very sound, as well as painting the scene " The bees bustling Down in the blue bells." But it would be as impossible to insert here the thousand beautiful allusions to the Honey-Bee to be found in the poets of all time, as to go into the wonderful details of Bee history. Nor is it needful ; for who has not read them again and again ? With one choice and chaste, though seldom-quoted passage from Leigh Hunt, therefore, we will send the little fellow about his business the business our fragment so prettily alludes to : " Wax-lights, though we are accustomed to overlook the fact, and rank them with ordinary commonplaces, are true fairy tapers a white metamorphosis from the flowers, crowned with the most intangible of all visible mysteries, fire. Then there is honey, which a Greek poet would have called the sister of wax a thing as beautiful to eat as the other is to look upon ; and beautiful to look upon too. What two extraordinary substances to be made by little winged creatures out of roses and lilies ! What a sin- gular and lovely energy in nature, to impel those little creatures thus to fetch out the sweet and elegant properties of the coloured fragrancies of the garden, and serve them up to us for food and light ! honey to eat, and waxen tapers to eat it by." The proper place for this beautiful passage is surely not the author's "Table Talk," whence we take it, but amongst the other sweet and pleasant thing in that famous " Jar of Honey from Mount Hybla." BEE BROTHERHOOD. 57 We have now something to say about the Honey-Bee's nume- rous kinsfolk and acquaintance. Novices in this matter will perhaps be surprised to learn that the Bee brotherhood is a very numerous one, something like two hundred species being found in Britain alone. If anybody desires to cultivate the acquaintance of this large circle, we recommend him to procure at once the " Catalogue of the Bees of Great Britain," by Mr. Frederick Smith, of the British Museum a book which, though published in the official blue, and in fact, no less than in name, a catalogue, is yet so full of interesting facts, the fruits of some twenty years of loving study and observation, that it seems to have a perpetual hum of Bees about it, and sends the mind off perforce to the wide-spreading heaths and commons, all aglow with the " bonny blooming heather," where the air is ever filled with bee melody. Next to the Honey-Bee, the best-known members of the tribe are doubtless the Humble-Bees, which are amongst the first to greet us in early spring. In Hampshire these insects are " Dum- bledors ;" in other districts "Bumble-Bees" and "Hummel- Bees ;" while in Scotland the brown species are known as the " Foggie-Bee," no idea apparently existing that there is more than one species of that colour. The Humble-Bees are all social insects, and live in communities, consisting, as in the case of the Honey-Bee, of males, females, and workers, the number of indi- viduals in each nest being small, however, in comparison with the teeming population of the hive, and never exceeding two or three hundred. The nests of these insects are for the most part constructed on the surface of the ground, in meadows, pastures, and open woods, the material employed being moss, when the builders can get it, and when not, any convenient material that comes to hand. Mr. Smith mentions a case in which a knowing " Foggie-Bee," being hard driven for material for her domicile, repaired to a stable, and gathering up little bundles of the short hair which had been curried from the horses, set about composing her nest entirely of horse-hair. In the case of some of the Humble- Bees, the nests are built under ground ; and this difference in habit is marked, it seems, by a great difference in the spirit of the architects, for while the above-ground builders exhibit very little courage or pugnacity, the dwellers below defend their nests with much resolution. The Solitary-Bees exhibit great diversity of taste in the matter 58 HA.BITS OF SOLITARY-BEES. of house-building. In the pleasant pages of Kirby and Spence they stand arranged as Clothier-Bees, Carpenter-Bees, Llason- Bees, Upholsterer-Bees, and Leaf-Cutting Bees, to which amplo list of Bee tradesmen Mr. Rennie, in his " Insect Architecture," very properly adds the Mining-Bees. These designations arc of course somewhat fanciful, though there is sufficient foundation in fact to allow of their use ; and there is this further resemblance between the human and the bee* worker, that when, from local circumstances, one trade fails, or cannot be followed, the in- dustrious insect can, as easily as the industrious man, turn his hand to another : the carpenter becomes mason, or the mason, miner. In the situations chosen for the construction of the nest, and the manner in which the nest is formed, there is au almost endless diversity. The Mining-Bees form their excava- tions very commonly in the sunny sides of clifis and sandbanks, or in hard and beaten pathways this latter fact having been noticed so long ago as the days of Homer. The Carpenter-Bees tunnel out old posts aud railings, or the decaying trunks of trees. The Masons build their nests in the holes of trees and the cracks of walls, and sometimes in such curious places as the empty shells of snails, that lie half-buried in hedge-banks. Some of the smaller species tunnel out the pith of bramble stems ; while others find a convenient abode in the hollow tubes of straw thatch. No place that can in any way be made available comes amiss ; and he who " loves to hear the wild bees' hum," and follows them in their various haunts to study the details of their history, will often be struck with their strange and wonderful devices in obviating difficulties, and accommodating themselves lo circumstances. In the summer of 1857 we discovered a most singular habit in one of the Carpenter-Bees, which, so far as was known at the time, had never before been observed. The Bee in question is a little fellow, with a thin, elongated body, and rejoices in the name Chelostoma florisomne, which, however frightful it may look in entomological Latin, is both pretty and appropriate when rendered into English, as the " lip- mouthed flower sleeper." The first part of this name speaks for itself, and the second is thus explained : Our little Bee is of a convivial turn, and is given to staying out at nights. Occasionally, therefore, of a summer evening, instead of returning home to the old post or rail in which his nest is CURIOUS DISCOVERY. 59 tunnelled out, it betakes itself, with some half-dozen boon com- panions, to a capacioufcdandelion, and there makes a night of it. The darkness coming on the flower, of course, shuts up ; and then the boozy company, huddled up together, have to pass the night as best they can. In early morning, when the flowers arc first opening to the sunshine, you may often light upon theao little knots of topers, in that stupid, half-awake condition which plainly warns you they have- had a jovial night. The tiling is of constant occurrence, and hence the name the little tipplers bear. Now for our discovery, which relates, indeed, to another and still stranger manner in which this little Bee sometimes passes the midnight hours. In searching along a hedgerow one after- noon, we came upon a spot where a number of small Bees v ere flying about a dead bush of hawthorn, which had been thrust into the hedge to stop a gap. Looking closely at the dead and leafless bush, we were surprised at seeing a considerable number of the Bees impaled, apparently, on the points of the thorns ; but a nearer inspection showed us that the little fellows were voluntarily holding on to the thorn points with their mandibles, their bodies being held out straight and rigid, and their legs folded placidly beneath. Our presence seemed in no way to in- terrupt them, and continual fresh arrivals at the bush came and settled within a few inches of us. It was a curious spectacle, and we watched it intently. The little fellows all assumed their attitude of repose in the same manner, first alighting on a twig 01 the bush, then getting on the chosen thorn, with their heads towards the point, and when at the very extremity, turning themselves round, seizing the point with their mandibles, and stretching out their bodies straight and stiff. It was getting late, and suspecting the insects were settling themselves for the night, we visited the place again early the following morning, when, to our astonishment, the thorns were still bristling with Bees, that had apparently remained motionless throughout the night, still holding on by their jaws alone ! We wrenched off a twig with a dozen of the Bees attached to it, and yet not one of them relaxed its hold : we held it up, swung it as we went along, and still they held on, and kept their bodies out as rigid as before ! Xcver having seen any record of this singular habit, we wrote to Mr. F. Smith on the subject, and he brought the matter before 60 THE GLOW-WOKM. the Entomological Society as a circumstance equally new to himself. Oddly enough, however, a few months later, Mr. Smith received a notice of similar observations on several allied species of these insects from M. Gueinzius at the Cape of Good Hope, and twelve months after these observations of M. Gueinzius were published, and nearly two years after the publication of our own, Mr. Edward Newman inserted in the " Zoologist," a short note, in which he announces that he has been familiar with the fact for nearly thirty years. It seems, therefore, that, curious as it is, there is nothing absolutely new in this discovery of " Bees roosting by the mandibular process." No order of insects perhaps exhibits a greater variety of forms and of corresponding habits than the Coleoptera, or Beetle tribe not including, however, the so-called Black-beetle, that pest ot most London houses, and of many country ones to boot, which in reality is not a beetle at all, but a near connection of the cricket and the grasshopper. In exchange for the " Black-beetle," the coleopterist claims the Glow-worm, which is his of right, with a good many of the " fire-flies " of tropic lands. It is now pretty well known that it is the female Glow-worm alone that lights up the little lamp to be seen in our hedgerows in summer, although the poets have very commonly assigned the function to the male, which is only slightly luminous, and is rarely seen. Thus Shakspeare has " The glow-worm shows the matin to be near, And 'gins to pale his ineffectual fire." Cowper also, in his verses on the insect, does the same " Tis power Almighty bids him shine, Nor bids him shine in vain." And Eogers, in his verses on the fire-flies of the Tusculan groves, in his poem " Italy," gives us " him " and " his " throughout, in his references to our own Glow-worm. Both Montgomery and Moore, however, give the lady-beetle the credit that is her due, and assign the true reason for the display, when, as the former says, she lights her lamp " To captivate her favourite fly, And tempt the rover through the dark." The light is most intense in those females which have only re- HABITS OF THE GLOW-WORM. 61 cently emerged from the pupa state ; and on calm dewy evenings, in June or July, they may frequently be discovered wandering restlessly about in their favourite haunts mounting the blades o. grass and other slight eminences twisting their bodies right and left and flashing out their light into the darkness of the night, to signalize the roving males of the whereabouts of their situation. The two sexes of the Glow-worm differ greatly from each other in appearance ; the female being a wingless, elongated, flat-bodied creature, possessed, however, of six legs, and in other respects very unlike a " worm ;" while the male is a true beetle, endowed with wings and wing-cases, and a pair of immense eyes, which are evidently intended to facilitate the discovery of his morn, brilliant mate. But those fine eyes are apt at times to deceive the gentleman, for he is easily lured by artificial light, and some- times wings his way to swift destruction. We have two of these insects which flew to us one summer night while sitting with a lamp at an open window ; the little rovers having doubtless been attracted by what they mistook for an unusual display on the part of some fair lady. It is a pity to say anything ungracious about a little creature so wrapped up in poetical associations and pleasant memories as the Glow-worm, and yet the truth must be told. It feeds, then, good reader, not on violets and primroses, not even on the common greenery of the hedgerows, but on flesh the flesh of enails, and eats it most voraciously ! The Glow-worm strikes at the snail as it crawls along, and by repeated bites speedily para- lyzes and kills its prey, which it then commences devouring, and seldom leaves for more than a few minutes until the whole of the body is consumed. The voracity of the little creature is ex- treme, and one may sometimes see four or five of them together in a snail-shell, feasting and gorging upon their prey, plunging their little heads and erected mandibles into the viscera of the snail, and continuing thus for hours together. And this fierce and rave- nous little creature is the Glow-worm ! "Well may we say with Mr. Douglas, " Let us draw a veil over the scene, and, as with some examples of human genius, be content with the ultimate lustre, without inquiring into the minutiae of its origin and support."* * The World of Insects : a Guide to its Wonders. Van Voorst. London 62 ANTS'-NEST BEETLES. The attention of coleopterists has been a good deal directed of late years to a tribe of small Beetles, which are found in the nests of various species of Ants, by whom they are watched over and provided for with the greatest solicitude. The loves of the Ants and the Aphides having long been celebrated, and the con- nection between these Beetles and the Ants, in whose nests they are retained, appears to be of a very similar character, and scarcely less remarkable. It is extremely curious to observe the anxiety which the Ants manifest for the safety of the Beetles, when a nest containing any of them is disturbed. Immediately the covering of the nest is removed, the Ants seize the Beetles in their mouths, and run off with them to the interior chambers of the nest in great alarm : and if, in the confusion of the moment, one of the Beetles should chance to escape beyond the boundaries of the nest, some of the Ants, directly it is seen, set off in pursuit of the runaway, and bring him back nor are they at all disposed to part with their burthen to the collector. The subject is by no means fully investigated as yet ; but so far as is at present known, the Ants retain these Beetles, as they attend the Aphides, solely for the sake of the secretion they obtain from them. It appears that the Beetles are for the most part kept quite secluded from the outer world, and are wholly dependent for support on the Ants, who are said rather fancifully we suspect to feed them with the juices of flowers. These Ants'-nest Beetles being but sparingly represented in most of our collections at present, the poor Antg have their establishments sadly tumbled about in the eagerness of collectors to secure specimens. The ardour of the search is considerably enhanced by the fact, that some of the species already found here are extremely rare, and that it is quite possible others not yet known as British may turn up in a lucky moment. But if the prizes are great, the expenditure of time and trouble to secure them is not small. The instructions that are given as to the proper mode of securing these pigmy treasures, are rather dis- couraging. In order to go to work successfully, the first business is to convey a supply of large rough stones or bricks to the wood which is to be the scene of action ; that done, three or four ot the stones are to be placed around the sloping sides of every ant's nest, and then your traps are laid. Now visit the nests as often as possible distance of course not to be thought of: tie your MODE OF COLLECTING. 63 trouser-legs and coat-sleeves tightly about your ankles and wrists, and turn up the stones. If the objects of your search are to be had, they will be found on the under surface of the stone, or beneath it. If not successful with one stone, or one nest, try another, and another, and still another. In the search after rarities, patience is indispensable, for not more than one nest in twenty contains beetles ; and in the case of special rarities, the collector may have to wait for years before his eyes are gladdened by the sight of the long-desired prize. If any reader should fancy he could improve upon this " patient " system by opening tip the Ants' nests, and prying narrowly into their recesses, let him beware. In the first place, the Ants themselves would resent this procedure in a fashion not comfortable to the collector; and, in the second place, so great would be the ire of the whole brotherhood of beetle- catchers, that the innovator, if detected in the act, would be in danger of a ducking in the nearest horsepond. The truth is, that by upsetting the Ants' nests, the Ants themselves are destroyed, and all possibility of future profit from them taken away. It is like killing the goose that laid the golden eggs. In France, moreover, this wanton destruction of Ants' nests is now strictly prohibited for another reason. The proprietors of woods, and others interested in the preservation of game, discovered that the reckless proceedings of the entomologists threatened speedily to extirpate the Ants, and thus to deprive the young pheasants and othei game birds of their chief source of subsist- ence. On this account, an interdict has been laid upon all further entomological havoc. Let all collectors, therefore, either adopt the " patient " and " laborious " system described above, or leave the Ants'-nest Beetles alone. The great body of the collectors of insects in this country give their attention more or less exclusively to the single order Lepidoptem. The Butterflies and Moths are so much more gaily coloured than most other insects, and make such an attrac- tive display in the drawers of a cabinet, that it is no wonder they hold the first place in popular favour. In the literature of entomology, too, these insects hold the first rank ; the splendid works that are devoted to their illustration more than eclipsing all that are published on all the other orders put together. The grandest book of this sort yet published is Dr. Herrich-Schaffer's 64 MICRO-LEPIDOPTEIIA. great work on the " Lepidoptera of Europe," completed only twd or three years since, and now to be had in six quarto volumes for the sum of thirty pounds ! No less remarkable in its way, how- ever, is Mr. Stainton's " .Natural History of the Tineina ;" a work which, though elucidating only one section of small moths those, namely, allied to the Clothes-Moth, and which are for the most part much smaller even than that little depredator is yet pub- lished in four different languages English, French, German, and Latin printed in parallel columns, and in illustrated octavo volumes, of which there will probably be upwards of twenty be- fore the series is complete ! The little Moths which are thus being honoured with a polyglot history, and portraits executed in the highest style of art, are amongst the most beautiful, and, in the details of their private lives, the most interesting members of the entire lepidop- terous order. In the larvae state they are very generally what are termed " leaf miners," the minute caterpillars living on the fleshy pulp of leaves, between the under and the upper skin, where, like the students of our Inns of Court, they eat their way, pro- ducing those white blotches and tortuous lines so often seen on the foliage of plants by the way-side. There is, however, an almost endless diversity of habit among these " micro " larva?, some species feeding externally, others in rolled-up leaves, others again patching out for themselves little cases from the old clothes in our cupboards, or the linings of our sofas ; while several species creep, snail-like, over old walls and palings, in cases constructed of bits of grass or particles of earth. Some of these case-bearing larva?, besides eating the soft pulp of the leaf, make use also of the skin itself, out of this constructing their conical teat-like cases, in which they wander about, always in danger, apparently, of having their houses toppling over, and looking the oddest little creatures imaginable. It is wonderful, too, to notice with what careful instinct these little tent-dwellers spin down their cases to the surface of the leaves, when about to moult or pass into the pupa state ; though Messrs. Kirby and Spence, with a love for the marvellous which is always apt to carry them astray, have in one instance singularly misunderstood the nature of this precautionary measure. " The caterpillar of a little moth," we are told, " knows how to imitate the air-pump, producing a vacuum, when necessary for its purpose, without any HISTORIAN OF TINEINA. 65 piston beside its own body ;" the simple fact being that the caterpillar in question spins down its case a little firmer than its fellows, though by the same means, and without in any way imitating the action of the air-pump. It is due to the historian of the Tineina, before passing away from his protege's, that we should make mention of his eminent services to the cause of entomology. No one living has laboured more arduously than Mr. Stainton on behalf of the science he loves so well ; and though, as we have before intimated, the new edition of the " Introduction to Entomology " has greatly contri- buted to the present increased popularity of entomological studies, it is in a great measure to Mr. Stain ton's previous exertions that the republication of that work is due. In his capacity of editor of both " Annual " and " Intelligencer," Mr. Stainton is exert- ing a wide-spread and powerful influence over the rising race of entomologists ; and though it is very probable he may have amongst his readers many more mere collectors than earnest students of insect economy, it will not be his fault if, with re- peated wise counsels and intelligent advice, they do not all become entomologists worthy of the name. One thing which greatly pleases us in Mr. Stainton is, that, while he can be precise and technical when occasion requires, he has yet the knack of infusing a genial pleasantly into all his writings, and with a keen relish for the beauties of nature himself, con- trives very happily to set them forth for the benefit of his readers. In the little volume, "June," most appropriately called " A Book for the Country in Summer Time," there are many passages which bear out what we have said ; and that our readers may judge for themselves, we will insert here a little word-picture from another source, which, though meant for children, has about it a charm that older people will admire. It is one of the passages from the "Educational Sheet of But- terflies" which should find a place in every schoolroom and mirsery : " It is the summer-time, the pleasant, happy summer-time. The lattice cottage -window stands open ; the caged thrush sings merrily on the outside, half concealed by the bower of roses and honeysuckle. The good wife comes to the door, to see if her husband is yet returning for his mid-day meal. She glances round the garden, and spies, sitting on a marigold, a butterfly, 66 THE BUTTERFLY BATTLE. gorgeous with all the colours of the rainbow in short, a peacock butterfly. " Just then John puts his hand upon the gate. ' Oh, John, such a beautiful butterfly !' ' Where ?' says John. ' There,' says Jane, pointing to the marigold, on which something like a leaf of a dull brown-black colour was sitting. ' Call that beauti- ful ?' said John ; and he lifted up a stone to throw at it. ' Yes, John ; see, see !' and as she spoke it opened it wings, and again displayed its glories. It walked across the flower, turning round the while. ' It is beautiful,' said John ; and he let the stone drop, half ashamed. They both stood watching the butterfly for some minutes, and saw it unfold its long spiral tongue to suck the honey from the flower. " Presently another butterfly, much smaller, came to the very flower on which the peacock was sitting. The peacock rose to repel the intruder; but the new-comer, which was a small copper, and not a fourth of the size of the original occupier of the flower, was not to be easily intimidated, and fiercely gave battle. ' Eh ! there's pluck for you,' said John. ' True,' said Jane ; ' I wonder at the impudence of the little creature.' But the battle was ended ; the peacock had gone into a neighbour's garden ; and the small copper returned in triumph to the marigold, and dis- played its splendid livery of burnished copper, now seen in all its glory, as the sun shone brightly from behind a cloud. John took more notice of butterflies after that day." A small matter, reader, truly ; but is there not a glow of sun- shine upon it ? The Small Copper and the Peacock, however, beautiful as they are, belong to the commonalty of the butterfly tribe, and may be had almost everywhere, and without much trouble. It is just the same with some others that are equally pretty, as, for example, the Common Blue, and the dainty Orange Tip, not to forget the showy Alderman or Pied Admiral, which, in their favourite haunts, may be found in abundance throughout the country. Not so is it, however, with others of the number ; and great is the flutter amongst the green gauze nets when the season ap- proaches for any of the rarities to appear. The reader may judge of the excitement that obtains amongst collectors when anything particularly ** good " is to be had, by the following announcement, taken just as it stands, from one of the numbers of the " Intel- ligencer :" TRAPPING AN EMPEROK. 67 ' LATEST INTELLIGENCE. " Colias Hyale and Edusa have both just been captured near Bognor. Further particulars in our next." Further particulars in our next! One could almost fancy it was the first intimation of some fearful railway accident ; and it certainly does look like being " serious upon trifles." Still, the Clouded Yellows are fine butterflies, and those who know them, and how difficult they are in some years to obtain, will not be surprised at a little enthusiasm. One of the greatest prizes amongst our native butterflies is Apatura Iris, which occurs in the woods of the south. This is the insect of which Crabbe sings " Above the sovereign oak a sovereign skims, The purple emp'ror, strong in wing and limbs ;" and, unfortunately for the collector, it is high up above the oaks and quite out of reach that the Emperor is most frequently seen. Like some other imperial personages, however, Iris is said to have a gross appetite, and has at times been captured while feast- ing on garbage by the side of muddy pools ; and a case is re- corded in which a collector captured no less than eighty of these insects, within a few days, by the simple expedient of nailing against the side of a house, in a wood where they occur, a bit of rabbit-skin and the wing of a bird ! One would hardly have thought that such a commonplace device would have so gone to the heart of an emperor. In collecting Butterflies, the course is easy enough, the col- lector having the daylight in his favour. But how shall he obtain the Moths, which, for the most part, fly only at night ? Well, in the first place, he can collect the caterpillars, or dig for the pupse, which he can do by daylight, and then rear his specimens, and so obtain them in a much finer condition than any he can get by other means. But the Moths themselves may readily be captured. The ingenuity of collectors has not only overcome the difficulty which the nocturnal habits of most of the tribe interposed, but has rendered it even easier to obtain the night-fliers than those that flit about by day. The first and principal device employed is that of " sugaring." The collector, armed with a mixture of sugar and beer, goes to the woods or 68 SUGARING AXD LIGHT. lanes, or stays at home in his own garden, and as the dusk draws on, spreads the tempting mixture in broad patches on posts, and palings, and the trunks of trees ; and, before long, lo ! the sweet aroma has reached the keen sense of the Moth community, who come forth from their secret hiding-places, and flock in troops to the spread-out banquet. But alcohol is alcohol, even to Moths ; and when, after a while, the collector goes his round with his bull's-eye lantern, the lon-vivants who have been lured so easily fo suck his sweets are boxed without resistance. The revolution that has been wrought in our collections since this mode of capture came into use, has been extraordinary. Insects which were before accounted rare, are taken in abun- dance ; and new species have been added to our list, which the cunningest collectors before had failed to capture. But there is one tribe of Moths, containing some of our largest and most beautiful species, for which the sugared post has no attractions. They practise the most rigid total abstinence, and are never once to be seen amongst the alcoholic revellers. But the collector knows them, and their weak points too. For them he has the open window, and the lamp upon the table. Light now does what sugar failed to do before ; and the collector will sometimes have a levee, in which fresh comers continue to arrive the whole night long. The largest of our native Lepidoptera, the great Death's Head Hawk-Moth (Acherontia atropos'), is some- times taken in this manner, and occasionally pays an unwelcome visit to houses, where his huge form and his ominous squeal spread terror amongst the inmates. In some places the street gas-lamps attract a considerable number of Moths ; and one of Mr. Stain- ton's correspondents has lately been expatiating on the advantages to be gained from " making friends with the lamplighter." Another method employed by collectors a method which sometimes does what neither sugar nor light can accomplish shall be given in the words of Mr. Douglas : " In May the Fox- moth careers madly over the fields now close to you, now out of sight ; yet there is ' method in his madness ;' he is fiercely in love, and is in search of his bride, who rests passively expecting his attentions, and good-naturedly or pettishly waiting till her lover's vagaries are over. Observe the spot he most alfects, and by looking carefully, you will probably see his lady-love deep among the heather, or ascending the stems ; then station yourself SiiL r :irin< for Moth-;. Page 68. SALLOWS AND IVY. 69 near, and you will soon have a chance of catching the rover ; but, as he conies like a whirlwind, it is most likely you will miss him if you strike too soon : the Fabian policy is the best, and you will succeed by delay." It is a common plan with the collectors in the north, when they have reared a female of the Fox-moth, or any of its allies, to take her to some locality fre- quented by the species, and, by means of her attractive powers, gain possession of many of her gallant admirers. The lady, of course, is safely secured from her suitors, who, with a marvellous power of discovering her whereabouts, come hurrying on from all points of the compass, and crowd about her cage perfectly regardless of their own safety. There are several of these wild, day-flying Moths, including the beautiful Kentish Glory (Endro- mis versicolor") the males of which may be taken by this means far more readily than by any other, though it generally happens that their headlong flight has considerably damaged their ap- pearance. In addition to these modes of capture, which the collector devises for himself, twice in the year, at least, he finds a glorious opportunity of adding to his store provided ready to his hands. The first of these comes with " The satin-shining palm, On sallows in the windy gleams of March," and the second, towards the close of autumn, when the ivy puts out its rich clusters of colourless blossoms. " Sallows " and " ivy," therefore, are most suggestive words to the collector of our nocturnal Lepidoptera, reminding him of occasions when, with little trouble, he may gain possession of several much- coveted species, not otherwise easy to obtain. The truth is, that the " palm" of the sallows, and the more ordinary blossoms of the ivy, not only attract the Moths in great abundance, but seem to have the same intoxicating influence over them as the pre- pared " sugar," so that the collector has but to go with his lantern after dark and beat the bushes over his net to make sure of a plentiful supply of incapables, from which he can select the prizes at leisure. Nothing is more curious than the striking differences which obtain with respect to the area over which certain insects are 70 DISTRIBUTION OF SPECIES. distributed. It has already been stated that some of our native Lepidoptera are to be had in almost equal abundance in all parts of the country alike, but there are several species whose range is just as restricted. Thus one of the Skippers a group intermediate between the typical Butterflies and the Moths is confined almost exclusively to a spot on the Dorsetshire coast known as Lulworth Cove ; although it there occurs in such profusion, that Mr. Douglas once caught a hundred in about two hours, frequently taking five or six in his net at one stroke. But a far more curious case is that of a little Moth (Boletobia fuliginaria) that from its colour deserves the name of the chimney-sweep, and which has occurred in this country nowhere but in the metropolis, the only recorded localities for it being, of all places in the world, Blackfriars Bridge, Fleet Street, and a coal-cellar at Chelsea ! Between this extreme of restriction in range and the almost universal diffusion of our commoner species, there is every possible variation. The beautiful Hawthorn Butterfly, or Black- veiued White (Aporia cratcegi), is now one of oui most local species ; but some years ago it appears to have been widely distri- buted, and in the neighbourhood of London its caterpillars used every spring to do great damage to the fruit trees. Occasionally it happens that insects, which are usually accounted somewhat rare, make their appearance in great profusion. The Clouded Yellow already noticed is one of these ; so also is the great Death's Head Hawk-Moth, which a few years since occurred in such abundance, that the pupa: were turned up by the hundred in potato-fields in all parts of the country. But a still more remarkable instance is that of the Convolvulus Hawk-Moth (Sphinx convolvuli), which, though almost unknown in the larva state, and generally an insect of rare occurrence, has yet on two or three recent occasions been taken in abundance all over the country ; one specimen which fell in our own way, having been found one morning comfortably settled on the knocker of a street door in the classic region of Shoreditch ! The old collectors say that these seasons of profusion come round periodically, and they point to the lovelv Painted Lady (Cynthia cardui) as an insect which swarms in this way every seventh year. Our own experience, however, would lead us to doubt the truth of this assumption ; and, in so far as Cardui VARIETIES IN FLIGHT. 71 herself is concerned, who, by-the-way, is a "bonafide " beauty ivithout paint," we have always found her far too coy and uncer- tain to be able to count upon her special appearance with any such regularity. Gilbert White states that a little attention would enable an observer to distinguish the different species of birds by the character of their flight ; and the same remark holds good of insects, but more especially of the Butterflies aiid Moths. The Skippers tell the story of their flight in the name they bear ; and in the same way that gay little visitor to our gardens, the Humming-Bird Hawk-Moth has earned its name, its habit of poising itself over flowers, and the vivacity of its movements as it darts from point to point, giving it a striking resemblance to the tiny feathered gems of the American tropical forests. In the dusk of evening, the snowy Ghost-Moth oscillates to and fro over the tops of the long grass, in the fields and churchyards'"; and in broad daylight, in crowded city thoroughfares, the littlo Vapourer-Moth hurries wildly along in its zigzag path, and like that famous pig immortalized by Leigh Hunt, in his essay " On the Graces and Anxieties of Pig-driving," dances " up and down all manner of streets." The insect most famous for the elegance of its flight is the White Admiral, so named from an oblique white band which stretches across the sooty upper surface of its wings; and there is a story told of a veteran collector, who when no longer able to take the field afoot, used regularly to drive out to the woods and take his seat on a gate, where he could feast his eyes in watching the graceful evolutions of his favourite fly. One day, perhaps, we shall see this old gentleman on canvas, " happy as a king ;" and the picture will form a capital com- panion to that of the gouty Waltonian, muffled up in his bath- chair, plying the angle in a water-butt. But we must pause. Let us say, in concluding, that the pleasures of entomology are only half enjoyed by the stay-at- home student. In order to know what the delights of the science really are, one must go forth afield, and study the busy tribes in their own proper homes ; and there is this additional advantage in so doing, that, besides attaining his special object in observing or collecting insects, the entomologist enjoys, as few 72 GENTLEMAN WAIFE. others can, the beautiful scenes amid which he plies his voca- tion. It is quite true, as Gentleman "VVaife puts it, " Fortune and Nature are earnest females, though popular beauties; and they do not look upon coquettish triflers in the light of genuine wooers." 73 CHAPTER IV. AN APOLOGY FOB SNAILS. " Aii inadvertent step may crush the snail That crawls at evening in the public path ; Yet, he that has humanity, forewarned, Will step aside, and let the reptile live." IT will be better, perhaps, to begin by frankly confessing that we have ourselves a great partiality for Snails. We admire them, make pets of them, and feel rather pleased than otherwise ; therefore, when they make themselves at home in our little back garden, which is very neat and pretty, the neighbours say, notwithstanding. The admission we have made will be a very damaging one, no doubt, in the estimation of all grave, sober-minded people ; and we are not sure that it is altogether politic to be so forward with the avowal. But as it is, we openly acknowledge the predilection. Nay, more than that, we are prepared to defend it ; and make bold to assert that there is not one person in a hundred always excepting, of course, market-gardeners and amateur floricultural monomaniacs who, if he (or she) were better acquainted with the Snail fraternity, would not regard them with something more of kindly tolerant feeling, even if they did not go the length that we do, of positively admiring them. The truth is, we have been so led away by prejudice and foolish antipathy against the little familiar things that are constantly before our eyes in fields, and gardens, and hedgerows, that we assume, as a matter of course, there can be nothing worth knowing about them ; and if they at all incommode us, or do the slightest harm to our possessions, they are straightway doomed to a pitiless extermination. But surely it is high time that we began to understand these matters a little better. If there be one thing more than another that the researches of our 74: ORIGIN OF THE FAMILY. savants and philosophers have taught us of late years in respect to natural history, it is that the're is, so to speak, nothing " common or unclean " in Nature's works ; and that, if we only use our eyes to see it, we may often find more of interest and beauty in the little and unheeded objects at our feet, than in those that men have gone to the ends of the earth to obtain. Who ever dreamed what a world of wonders there is in the strip of shore laid bare by every ebb of the tide, till Johnston, and Forbes, and Gosse pointed it out to us ? And, to go a little further back, could anybody ever have imagined that the insect tribes would furnish the material for such a treasure-house of pleasure and of profit as that dear old " Introduction to Ento- mology " by Kirby and Spence ? And so it is all through the animal series ; in the most familiar and insignificant members . of it there is still much to surprise and gratify to wonder at and admire. But, not to deal too much in these generalities, let us return to our subject, and affirm, that the Snails, much despised, he- kicked, and be-crushed as they have been and are, do really deserve more considerate treatment, to be got rid of undoubt- edly, if their rations are of consequence, but still to be looked at and understood. Our partiality for the race has led us to study their history, their curious structure, their habits, and general economy ; and not satisfied with the British representatives of the family, we have tried to pick up some information with respect to the Snails of other lands, and especially those of the " glorious tropics," where the family has its head-quarters, and puts on a very imposing appearance. The reader will bear with us, perhaps, for a brief space, while we discourse to him on these matters in no very serious vein, of course ; but still so as to make good our position, that your little, despised Mollusc is worthy of attentive consideration. We will open the case by claiming for the Snails the respect that is always accorded to old and long-established families. There were Snails before the Flood before Adam even in those far-remote eras of the past, when the lower orders of the animal creation had the world all to themselves. The family seems to have " come in " somewhere about the time when the huge Dinotherium wallowed in the rivers of central Europe ; and it is not at all improbable that some of the earliest members of it THE GARDEN SNAIL. 75 may have banqueted on the self-same herbage which sustained the enormous bulk of that unwieldy monster. Later down, in the classic days of Greece and Eome, the Snails were not only known, but held in great repute, and regularly had the honour of appearing at the tables of wealthy epicures, fresh from contact with a silver gridiron. It was in those clays, indeed, that the tribe derived the family name by which it has ever since been known Helix, a spiral, being the name that was given to the dainty morsel ; while the same term, metamor- phosed into HeUcidce, new stands, all the world over where the science of Zoology obtains, as the distinctive appellation of the wide-spread family. All that by the way, however : what we want to impress upon our readers is, that if there be any honour attached to long descent and distinguished connections, then that honour can fairly be claimed by the Snail family. It may be as well, too, to observe at once, that though the representatives of the family which make themselves at home in our fields and hedges have nothing particularly attractive in their appearance, that is not by any means the case with those branches of the family that reside abroad. In " foreign parts " there are Snails to be found as far exceeding our own in delicacy and beauty of colouring as there are birds and insects that excel in brilliancy the winged tribes of our woods and fields. But these gaily-coloured individuals belong, of course, to the rich pastures and the sunny skies of tropic regions ; and we do not mean to call in their aid just yet, in order to make good our position as to the claims of the family. Let us come back, therefore, to the little fellow with the dusky spotted shell that crawls across our garden-path, and to his somewhat prettier companions of the hedgerow. We will introduce them in due form Helix aspersa, the Garden Snail ; Helix nemoralis, the yellow or banded Snail of the wayside banks and hedges. And now observe that they make their way in the world by means of an expanded disc or foot, which, as it is in close contact with the ventral region of the body, has procured for the tribe a place amongst the great class of Gastropods, or belly-footed Molluscs. The foot itselt is a very curious organ, and consists of a nearly uniform mass of muscular fibres, interwoven much in the same way as those of the human tongue. The regular gliding motion with which the common Snails crawl along, is due to a pair of 76 DELICATE REVELATIONS. muscles extending along the centre of the foot ; but in eonie of the species the surface of the foot is divided by a longitudinal line along the centre, the muscles on the two sides of which act in rotation, and so cause the animals to progress in a perpetual zigzag. The glistening slimy tracks which they leave behind " the silver-slimy trails," as poor Clare calls them are pro- duced by a discharge of mucus, designed to protect their tender bodies, and smooth the asperities of their way. It must be a very comfortable thing for the Snails to be able to carpet their path in this easy off-hand manner, and we confess we like to see the silvery line on posts and palings or gravelly walks , but when, as happens sometimes, the little fellows pay us a visit, in our parlour, where the place is carpeted beforehand, they might be considerate enough to wipe their feet before coming in. We must not omit to mention in this part of our discourse, the pretty conceit that obtains in some parts of the country as to the power of the Snail to reveal to tender-hearted maidens the names of their destined sweethearts. May-day morning is the auspicious occasion on which the disclosure can alone be made, and never do the entire Snail family meet with so much consi- deration as on that happy day. The poet Gray alludes to the subject in his lines beginning " Last May-day fair I search'd to find a snail, That might my secret lover's name reveal ; " ana Croker, in his work on "Irish Fairy Legends," informs us that in Ireland it is the common practice of boys and girls on May-day, to place the little soothsayer on a piece of slate lightly sprinkled with flour or fine dust, and to cover it over with a large leaf, when it never fails to describe by its mazy wanderings the initial of the much-desired name. A good deal of discussion has taken place amongst naturalists, as to whether Snails have any eyes or not. The popular notion, of course, is that the little knobs at the extremity of their long leelers or horns are eyes ; and though several writers have ques- tioned or boldly denied the truth of this opinion, it seems to be now pretty generally conceded, that the little club-shaped pro- jections are true visual organs, Swammcrdam, indeed, long ago demonstrated the matter to his own satisfaction, and pointed out the five distinct parts of which the eye consists. But then he EYES AND HORNS. 77 made the mistake of calling the great nerve of the tentacle, and which is really the nerve of touch, the optic nerve ; and so his statements were all put aside together. Professer Owen speaks veiy confidently on the subject, and in the Museum of the Eoyal College of Surgeons he has one of those wonderful preparations with which he has enriched that noble collection, in which the tentacles of Helix pomat la are extended so as to show the eye at the side of each extremity. In this position the eyes, the pro- fessor very justly observes, although destitute of appropriate muscles, have the advantage of all the mobility with, which the tentacles themselves are endowed ; while, by the admirable con struction of the tentacles, they are securely defended from ex- ternal injury. It would be a difficult matter, probably, to find a person any- where who had never seen a Snail draw in its horns on their being touched ; but how many, we should like to know, have ever closely watched the Snail's manner of doing it? Those little horns, as the learned professor above mentioned properly says, are " admirable " contrivances, and the way in which they are so nimbly drawn in is not a little curious. The thing is easily seen, and any schoolboy may ascertain how it is done, the next time he stops a Snail in his travels across the footpath, and admonishes him, in the words of the old doggerel, "to shut up his house and go away home." The secret is, that the tentacle is a hollow tube, and in being withdrawn, it is simply inverted and retracted like the finger of a tight glove ; only that the extremity, with the eye-spot upon it, is always the first part to disappear. The manner of il. is best seen, perhaps, when, after the tentacle has been withdrawn, it is again protruded ; as you can then readily discern that the organ is lengthened, not by being pushed out from its base, but by gradually unfolding itself, or being everted at the extremity till the clubbed point appears, and the tentacle is fully extended. One cannot but admire the wisdom which thus gives the little Mollusc such a ready and effectual means of defending its rather oddly located visual organs. We speak of the wonderful contrivances connected with the human eye, but surely there is something here that is not much less wonderful. If we may rely on the experiments of Swammerdam, the Snail tribe have the sense of smell, as well as that of sight. The late 78 STRUCTURE OF MOUTH. Dr. Johnston inclines to this opinion, and assigns as his reason the fact, that when the little fellows have been snugly stowed away inside their shells, he has sometimes tempted them out by bringing near to them a little fresh food. But one thing is very certain they have the sense of taste, and are doubtless good judges of flavour. M. Gaspard (a great authority on Snails) disallows the tribe all the senses save those of taste and touch, the latter of which he admits they possess in an extreme degree of delicacy. The sense of taste ought to be well developed ; for, as the whole family are extraordinary eaters, one large source of pleasure would be lost to them if they did not enjoy their food. Mr. Gosse has a very graphic description of the Periwinkle in the act of mowing down his dinner of minute conferva from the glass sides of an Aquarium : the Snail is an equally interesting subject at dinner-time, though his method of feeding is a some- what different one. On the upper side of the opening of his mouth there is a semicircular horny jaw, which, by pressing against a sort of pad on the floor of the mouth, cuts off the frag- ments of its leafy food. But, besides the jaw and its pad, there is a pair of very serviceable lips, and a little membranous tongue, roughened over with minute prickles, all set in regular array, and pointing backwards, so as to retain more securely the food it has to manipulate. A Snail's tongue, by the way, is an object of no little interest ; and if any one doubts the statement, let him ask the opinion of any microscopical observer, and he will say you could hardly have a more interesting object to look at. The little points or prickles above mentioned are arranged so orderly and methodically, and in such pretty patterns more- over, the different sorts of Snails exhibit such a great variety in the shape of the tongue itself that they deserve to be ranked amongst the fairest specimens of Nature's dainty handiwork. But we were going to exhibit a Snail in the act of dining. When the little fellow is about to eat, then, it pushes forward its prickly tongue, at. the same tune protruding the lips on each side, till they both come in contact with what is designed to form the first mouthful. The lips then seize hold of the food, and draw it towards the aperture of the mouth, the tongue at the same time keeping it secure by the array of reverted prickles. Brought in this way within range of the horny jaw, the food is pressed upwards, and a small portion a Snail's mouthful detached; REMEDIAL POWERS. 79 this portion is then passed along the tongue, is torn and rasped by the sharp prickles, and finally pressed backward to the entrance of the gullet. Having a good deal of work to do in the way of eating, the little fellows manage to get along pretty quickly, and sometimes make a very audible noise while about it. Perhaps some of our curious readers the next tune they meet with a Snail on the look-out for provender, instead of crushing it or flinging it away, will be good enough to present it with a fresh cabbage leaf; in which case it is highly probable that, if they will only listen attentively, they will hear the little Mollusc lustily munching the proffered dainty, and smacking his lips with great satisfaction thereat. "We spoke above of flinging a Snail away unfortunately a calamity to the members of the Snail fraternity which they often have to bear; but against all irremediable injury from which they appear to be specially guarded. The consequence to the Snail of such (flinging is, of course, in most cases, a fall that makes a perfect wreck of the shell ; and no humane person, that once sees how painfully the poor creature writhes and sputters after such a crushing fall, would repeat the act. Not even a Snail may be put to needless pain ; kill it, by all means, but do not maim it merely, and doom it for weeks or months to bootless torture. The remedial powers of the Snail are truly remarkable. The repair of a broken shell is a small matter that is soon accom- plished ; while, under favourable circumstances, and in course of time, the most serious injuries or losses are made good. The Abbe Spallanzani, who had a strange taste for putting out the eyes of bats, and other scientific cruelties of the kind, cut away the tentacles of H. pomatia and nemoralis, and in about two mouths found them perfectly renewed, even to the eyes at the tips. In other experiments he removed not only the tentacles but the entire head, including the brain, the mouth and its ap- pendages, and a mass of the muscle, and yet the whole of the lost parts were reproduced, and with such perfection that it was im- possible in some cases to distinguish any difference between the newly formed parts and those that had been cut away. The poor Snails that were thus experimented upon retired into their shells the moment the operation was over, and there remained for many weeks and in some cases for months, in perfect quiescence, 80 EXPERIMENTAL MUTILATION. The year 1766, in which Spallanzani published the results of his experiments, inaugurated a perfect reign of terror for the Snails. The ardent Abbe, indeed, did for them just what Galvani, some years later, did for frogs and rabbits : he led to their being immolated by thousands upon the altar of science, with the view, apparently, of ascertaining how far it was possible to go in maiming and mutilating the poor Molluscs, without actually destroying life. The first result of these experiments was to throw discredit upon the extreme cases that Spallanzani had mentioned ; but more careful operators, in after-years, fully established the truth of his statements, and demonstrated the existence of those extraordinary powers of reproducing lost parts which he was the first to announce to the world. It is to be hoped that no ambitious young naturalist who may read these pages will be tempted to repeat the above experiments for himself, because we can assure him the facts are well established, and any further snail mutilation to confirm them would be only wanton cruelty. It would hardly be suspected that little fellows, with such cold and sluggish natures as the Snails possess, would manifest much warmth of passion. So it is, however ; and the Loves of the Snails has always been an attractive subject with savaitts, from the very singular circumstances connected with it. In reading Professor Rymer Jones's graphic account of the mat- ter, with its curious details of love darts and tender demon- strations the coyness on the one side, and the ardour on the other one is half inclined to think that you are again going over the story of the amours of the Olympian gods. In the great majority of the Helicidce, the young are produced in eggs, which are always globular in shape, and in some of the larger kinds enveloped in a hard calcareous shell. The eggs of the common Garden Snail are often exposed to sight on turn- ing up a stone, or slate, or piece of decaying wood, that has been lying long in some dank, unfrequented part of the garden ; and by an inexperienced person they would be very liable to be mis- taken for some out-of-the-way curiosity of Nature's making. They are about the size of small peas, and being of a beautiful pearly white, might be made into a very pretty string of beads, were they only durable enough for the purpose. We have some- times watched both Helix aspersa, and her cousin nemoralis, whea HYBERNATION. 81 they have been prying about for a suitable spot wherein to deposit their ova, and have more than once disturbed them in the midst of the operation ; and, despite all their frothy protesta- tions, have been tempted to despoil them of their little pearly globes. The spot selected for the purpose is generally some such an one as we have already mentioned, or else the eggs are buried beneath the soil, or in heaps of decaying leaves ; the particular habit in this respect varying greatly amongst the different species and genera of which the family is composed. The eggs of some of the larger tropical species are deposited in little clus- ters, high up on the foliage of stately trees, the parent Snail managing to curl up two or three of the leaves, one upon the other, so as to form a sort of nest for their protection. It is not necessary to do anything in the way of tracing the course of the young Snails from infancy up to old age and they do attain to a venerable age at times since, long as the Snail's life may be, it is by no means an eventful one. The only thing in it that need detain us at all, is the curious winter hybernation in which all the members of the Helicida in temperate, and in some of the warm, latitudes indulge. Almost everybody is familiar with the fact, that in the winter time our common Garden Snails are to be seen, by the dozen or the score, snugly stowed away in the cracks and holes of old walls and trees, under the eaves of barns and outhouses, and in other equally sheltered situations, where they remain, fixed and motionless, till the advent of spring. Other members of the family bury themselves in the banks of the hedgerows, amongst the moss at the roots of trees, or secrete themselves in the chinks and fissures of the naked rocks. Helix pomatia, with very high notions of its own dignity, is satisfied with nothing less than a comfortable hyber- naculum, which it constructs with great art and skill in the sides of ditches, in thickets, and similar places, and in which it sleeps soundly all the winter through, very little concerned as to what may be going on above ground. It is curious to observe that this period of inactivity, which in temperate latitudes is rendered necessary by the cold of winter, in the arid regions on the western side of the Andes is equally imperative on account of the terrible droughts which there obtain during the dry season. Heat here acts in one respect just as cold does amongst ourselves : the herbage withers a 82 TROPICAL DROUGHTS. and disappears, and the land is to a great extent denuded of its vegetable covering. The Snails of these regions, therefore, bury themselves, as the dry season comes on, in the sand or under stones, and covering the mouth of the shell with a sort of parchment epiphragm, like that formed by our own Snails in their winter retreat, remain in a torpid state till the return of a more genial season. Mr. Lovell Eeeve, in his great work on shells, the " Concho- logia Iconica," gives a curious anecdote illustrative of the peculiar character of the sterile region west of the Andes, and its effect on the Snail tribes. In 1829, when Mr. Cuming, the famous col- lector of shells, arrived at Copiapo, where the large Bulimi are to be found in considerable numbers, he desired one of the soli- tary inhabitants of the place to obtain for him as many of the living animals as he could get. When the native returned with his Snails, Mr. Cuming was surprised to find that there was scarcely one living specimen amongst them all, and reproved the man accordingly. " Only wait till the dews come," said the man, " and they will be all alive again." And when Mr. Cu- ming rejoined, " The dews ! I suppose you mean the rains," the poor fellow, with a look of astonishment, asked what he meant. He was a sexagenarian, but he had never heard of rain before ! In the British Islands there are in all between fifty and sixty species of the Snail family. The largest of our British Snails is the famous Helix pomatia, the Eoman Snail, as it is sometimes termed, from the high estimation in which it was held by the Eoman epicures. It is considerably larger than II. aspersa, more faintly coloured, and confined with us almost exclusively to the chalk districts of the south of England. On the Continent, however, it takes the place of our Common Snail, and in the wine countries does great injury, by its partiality for the buds and tender leaves of the vine. Our prettiest species is, without doubt, H. nemoralis, which is either yellow, chocolate-brown, or flesh-coloured, and abounds in every hedge and ditch-bank, throughout the spring and summer. It is often beautifully variegated in the neighbourhood of the sea. We have a number of the shells of this Snail now before us ; and sure we are there is no young lady living, who, if she were told that these shells were brought by some celebrated naturalist from China or Japan, would not pronounce them beautiful. Another of our widely- BRITISH SNAILS. 83 distributed species is H. arbustorum, which is generally found in woods and shrubberies, or amongst the willows on the banks of ditches and rivers. It is rather famous for extending its range, however, high up on the sides of mountains, on the Alps ap- proaching the line of perpetual snow. H. virgata, H. capcrata, H. ericetorum, and one or two others, affect the dry stunted vegetation on heaths and commons. According to Dr. Turton, they go down to the roots of the plants, and come up again after the summer rains, when they are so abundant, that, like the young frogs that leap in thousands over the same sort of places, they are supposed to come down from the clouds with the rain ! Cydostoma elegans, and several little fellows of the genera Pupa, Clausilia, and Bulimus, keep clear of all but initiated concholo- gists, secreted in woods and shady situations, under nettles and other plants not pleasant to handle ; Helix rupestris passes its days between the bricks and stones at the tops of walls, or in the earth on the higher parts of rocks ; the dainty little Pupa marginata, Achatina acicula, and one or two others, bury them- selves alive among the moss at the roots of trees. H. crystalline is a pretty little Snail, with a delicate, glassy shell, to be found under stones in damp places, where also, with sharp eyes, we may find the dusky-coloured H. pygmcea, no bigger than the head of a good-sized pin. Not to extend this list to too great a length, however, let us bring it to a close with the much-prized H. revelata, one of the rarest of our British Snails. It has a shell about a quarter of an inch in diameter, of an olive-green colour, and occasionally gladdens the hearts of collectors at Nottingham, in Cornwall, and in Devonshire, but more especially in the latter county, where, with tme aristocratic predilections, it confines itself to the select society of Torquay. We have been thus particular in referring to our British Snails, because studies of this sort, like acts of charity, should always " begin at home." But now that we have attended to the Snails of our own land, let us glance as rapidly as may be at some of their high and mighty relatives abroad especially at those of tropic lands, that go about clothed in gold and purple, and other fine colours, and which, according to some enthusiastic conchologists, look, as they cling aloft amongst the glossy ioliage, like the golden fruits in the Garden of the Hesperides. It is as well to know, perhaps, that the common Snail (11. as- 84 AFRICAN AND AMERICAN SNAILS. persa") is by no means confined to ourselves. It has, indeed, pretty much of a cosmopolitan turn of mind, and makes itself quite as much at home, though not in such great abundance, in the olive groves of the south of Europe, on the Asian and Afri- can shores of the Mediterranean, in the dense forests of Guayana and Brazil, and at the foot of Chimborazo, as in our own hedges and gardens. Nowhere, however, but amongst ourselves does it hold the rank of the "common" Snail that distinguished position being held in different lands by different members of the family. On the Continent of Europe, Helix pomatia takes the lead, and as we shall find by-and-by, is a much-prized Mollusc. In Africa, very generally the genus Acliatina takes the place of the more typical genus Helix, and presents xis Avith some of the most monstrous creatures belonging to the family. In Liberia there is an immense fellow, A. variegata, which, if it were to make its appearance on the banks of some English road-side ditch, would probably create a panic in all the neighbourhood around. In Guinea and Natal there is another monster, striped with black and brown like a zebra ; while all along that part of the African coast, these immense and richly-coloured Achatince abound, crawling like most of our own Snails on the ground, or on the low herbage in swamps, and in the vicinity of lakes and rivers. Some of the smaller, but still very beautiful, species of this genus occur in Central America and the West Indies ; but in this part of the globe another genus takes the lead, and the reigning monarchs of the Snail world belong to the Bulimus dynasty, which, being a very important one, merits accordingly our special attention. Our knowledge of these animals is in a great degree the result of the very extended and careful observations of a gentleman to whom we have already alluded in this Chapter Mr. Hugh Cuming, who for several years past has been in the habit of fitting out a tight little vessel at his own expense, and setting off for a twelvemonth's or a two years' trip to South America, Borneo, the Philippine Islands, or some other far-off part of the world, there to amuse himself in picking up shells, collecting ferns, and suchlike scientific trifles, and also in noting the ways and doings of the thousand things that he comes across, and then returning to this country to dispose of his accumulated spoils, and prepare for a fresh adventure. Mr. Cuming's roaming A TROPIC PICTURE. 85 days are pretty well over now, unfortunately ; though we hope he may yet live many years to enjoy the fruits of his labours, not the least agreeable part of which to him, perhaps, is the gratitude of all loving students of natural history for the many valuable additions he has made to their knowledge. But the Bulimi ! In the first place, then, in some of these creatures the animal itself is curiously spotted with conspicuous colours, as may be seen by a model of B. rosaceus in one of the cases in the British Museum. The animal is of considerable size, and over every part of its deep-green body there are, closely set, bright-red spots, which give one the idea that the poor Snail has been seized with a violent attack of the measles ! According to Mr. Cuming, this Snail hides itself away in the dry season under stones among bushes, and close at the edge of the sea- shore, where at times it gets sprinkled with the spray. On the hills they live on the leaves of an aloe-like plant, to which the giant humming-bird also comes to sip the honey Irom the bril- liant flowers ; and we are inclined to think that the strange-look- ing plant, with its bright flowers, and the Snails, and the hum- ming-birds together, must make a very attractive tropic picture. Some years ago several of these Snails were brought to this country alive, and were sent to spend their days amongst the palm-trees in Mr. Loddiges' nursery at Hackney, where for eight months they tried to forget the rich juices of their native aloes, by eating greedily of English cabbage-leaves ; but it would not do, and they died miserably at last, within a few days of each other. One of the most beautiful of the Bulimi is a species that comes from the Solomon Islands of large size, and clothed with a shell of the purest and most delicate yellow, while the lip, or the rim around the mouth, is of a brilliant orange red. The head- quarters of the tribe appear to be in Venezuela and New Gra- nada, where great warmth and moisture give a wonderful de- velopment to vegetation, and where, accordingly, Snails abound and banquet on the luxuriant pastures. No less than sixty different species of Bulimi alone may be found in these parts ; and at the head of the list there are the monstrous species, maximus, ovatits, valenciennesi, and hcemastoma, big as the clenched hand of a full-grown man, and beautifully coloured Snail giants that cling in bunches to many a splendidly-flowering cactus, eating into the very middle of its spiny leaves and stems, 86 PHILIPPINE ISLAND SNAILS. and adding by their own strange appearance to the singular aspect of the ungainly plants on which they feed. The pretty pink-mouthed Snail-shell, adorned with broad bands of white and chocolate-brown, that finds a place on many a mantelshelf and sideboard, is a species common in Ceylon, and which, though christened H. haemastoma, the pink-mouthed Helix, is quite as often iZoc^-mouthed as pink, and sometimes, though much more rarely, white-mouthed. Another pretty Cingalese is the dainty H. melanotragus, arrayed in pink or white, with delicate shades of brown; but, as its name may serve to denote, H. elegam carries off the palm for beauty from all the Snails within sight of Adam's Peak. In no part of the world, perhaps, do the shells of the Helicidoe present a greater variety of rich and delicate tints than in the luxuriant open forests of the Philippine Islands, which seem to be a sort of Paradise for the terrestrial Mollusca, as the shores of those islands are for such as live upon the borders of the " vasty deep." But we might as well attempt to describe an Italian sunset, or the glories of our autumn woods, as to convey in words an idea of the beauty of these beautiful shells of the far-off islands of the tropic seas, on which nature seems to have lavished her richest wealth of pure and delicate colouring. We are strongly inclined to suspect, that the fact of which Mr. Cuming gives us intimation namely, that none of the birds of the Philippines ever touch the superb Helix polycroa, the many-coloured Helix is no other than the result of a common understanding amongst the feathered tribes there, that, by thus refraining from all mo- lestation of one of the number, they would fitly express their high appreciation of the beauty of the entire Snail family. We ought, perhaps, before going further, to caution our wnconchological readers against assuming that all the different sections of the Helicidce carry about the same sort of globular or semi-globular shells as those of the species common in our own gardens and hedges. It is far otherwise, and is indeed somewhat singular, that, while the animals of this family are themselves substantially alike in form and structure, the shelly coverings which they secrete exhibit most remarkable deviations from the typical character. Not the least curious part of our subject is that which pertains to the Snail tribe as an article of food. It has already been ANCIENT SNAIL-STIES. 87 mentioned that H. pomatia was one of the delicacies that found its way to the table of the Eoman epicure ; but long before Romans or Home, not only H. pomatia, but Snails of all sorts saving and excepting, of course, that one notable case of If. polycroa served as dainty morsels for a variety of birds and quadrupeds, which are now asserted to thrive and fatten on the slimy fare. The hedgehog is well known to make great havoc amongst their ranks during his nocturnal rambles. Vast numbers of the smaller kinds are eaten by the sheep which graze upon the scant herbage of some of our waste lauds ; and there is still a doubt in our mind whether we ought not to attribute to this circumstance the superior flavour of South Down and Dart- moor mutton. Again, what country schoolboy is there who has not seen the thrush and the blackbird a snail-gathering in winter, and cleverly cracking the shells on some convenient stone to get at the dainty morsel within? In the vast forests of South America, the huge Bulimi are roasted and eaten by the natives as a frequent article of food : and one of our own childish recollections is of a terrible goggle-eyed, idiotic sort of white Indian, as we suppose he must have been, whom we often used to come across in the bowery Devonshire lanes, picking Snails and cracking them, and, all frothy and sputtering as they were, bolting them outright, for the benefit of his " chest." The Eomans not only ate Snails ; they reared them and fattened them up with as much care as we do our poultry. Pliny, indeed, has immortalized the individual one Fulvius Hirpinus who invented the " cochlearife," or sties in which the dainty fare was fattened for the table. There were several com- partments in the sty, and each compartment had its occupants from some particular district ; so that your cultivated epicure, with his nice discrimination of flavours, could select his Snails pretty much as the modern man of fashion can select his wine. The great perfection to which the Snails were brought under this system of fattening led to a hot competition as to who should have the biggest ; and in the end, as Pliny tells us on the authority of Varro, they were brought to such a size, that some of the shells would hold ten quarts ! The usual method of cooking the over- grown monsters appears to have been that of frying them, or else grilling them on a silver gridiron. In France, and some or the countries of southern Europe, //. pomatia, has been eaten 88 SNA1L-EAT1NO. from the time of the Romans to the present day. Only a few years ago the habitue of the inns of Vienna could as easily obtain his dish of Snails as a joint cf mutton or beef ; and in Switzerland they are still regularly fattened for sale, and during the season of Lent become an important article of trade. In former times, indeed, the Snail always of course understanding that H. pomatia is the individual meant was admitted to our own tables : and Kobert May, the Soyer of his time, has left us several receipts for cooking them, amongst the curiosities of his fifty years' experience. Ben Jonson, again, in his " Every Man in his Humour," mentions the dish as a delicacy : " Neither have I Dress'd snails or mushrooms curiously before him ;" while Lister, in his " Historia Animalium Anglia;," refers to the Snail as, in his day, an ordinary article of food. But, for some reason or other, the much-prized delicacy of former days has now lost its repute amongst us, and excepting in the case of the Newcastle glass-blowers, who are said to hold an annual feast, in which the common Garden Snail furnished the central dish is entirely banished, it seems, from our tables, without the remotest prospect of its ever again appearing thereon. Once, indeed, two great philosophers, lamenting over the per- verse and unreasonable antipathy of the age in rejecting an article of food at once so abundant and nutritious, determined to set the example of a return to the wiser custom of former days ; and with the story of that patriotic resolve, we must bring to a close this already too extended dissertation. The benevolent individuals in question were the two great chemical philoso- phers of Scotland, Dr. Black and Dr. Hutton particular friends, though extremely opposite in their appearance and manner, and in nothing more than in their style of language. Dr. Black spoke with the English pronunciation, with punctilious accuracy of expression both in point of manner and matter while, on the contrary, Dr. Button's conversation was conducted in broad phrases and expressed with a broad Scotch accent, which often heightened the humour of what he said. The two doctors were agreed that it was the height of folly to abstain from Snails, and would show their superiority to such a vulgar prejudice. Some Snails were accordingly procured, dieted for a time, and then PREJUDICE FERSVS PHILOSOPHY. 89 stewed for the benefit of the two philosophers, who had either invited no guest to their banquet, or found none who relished in prospect the piece de resistance. And philosophers are but men, after all. When the huge dish of Snails came to be placed before them, the stomachs of both doctors began to revolt against the proposed experiment. Nevertheless, if they looked with disgust on the Snails, they retained their awe for each other; so that each, concealing the symptoms of internal revolt peculiar to himself, began with infinite exertion to swallow, in very small quantities, the mess which he secretly loathed. Dr. Black at length showed the white feather, but in a very delicate manner, as if to sound the opinion of his messmate : " Doctor," he said, in his precise and quiet way, " doctor, do you not think that they taste a little a very little green ?" Whereupon the other, starting up from the table, and giving full vent to his feelings of abhorrence, vociferated, " green, green, indeed! tak' them awa' ; tak' them awa' !" prefixing, we are sorry to say, certain epithets which a sense of propriety forbids our inserting here. And so ended all hopes of introducing Snails into the modern cuisine; so philosophy gave way and prejudice gained another victory. 91 CHAPTER V. THE NAUTILUS AND ITS ALLIES. " The tender Nautilus who steers his prow, The sea-born sailor of his shell canoe, The ocean Mab, the faiiy of the sea, Seems far less fragile, and, alas ! more free. He, when the light'ning wing'd tornadoes sweep The surge, is safe his port is in the deep And triumphs o'er the armadas of mankind Which shake the world, yet crumble in the wind." No department of natural history lias been more fully and assiduously investigated of late years than that which relates to the lower forms of animal life, and especially to such as people the teeming waters of the ocean. The broad tidal belt of the sea-shore, alternately covered by the waves and left bare by the tide, in all its varied aspects of sand-flats and shingles, oozy shallows, and rugged festooned rocks, has in particular been diligently explored ; and the observations which have been made on the structure and habits of the different animals thus ob- tained have made a new and quite wonderful addition to our knowledge of organic life. A multitude of creatures have been brought to light whose existence was previously unsuspected, and amongst those which have long been familiar, but unheeded, the discovery has been made of a world of interest and beauty, which is hardly surpassed throughout the whole extent of the animal creation. In many cases, too, these observations and researches have led to the most important results in correcting and enlarging the current views of natural history, as a philoso- phical study at one time exploding some ingenious and long- cherished theory at another handing over a whole tribe of creatures from one division of nature to another ; now com- pelling a total revision of the accepted systems of classification and now disclosing a fact which has let in, as it were, a flood of light on some obscure point in the animal economy, and gone 92 RANSACKING THE DEEP. far to revolutionize and reform the whole compass of zoological science. It is not alone in the immediate neighbourhood of the land, however, that these investigations have been carried on, or that important discoveries have been made : the deeper waters at a distance from the shore have not been neglected, nor their inha- bitants allowed to pass unnoticed. On the contrary, the " drag " and the "dredge" have been plied so industriously in groping up the contents of the sea-bottom, and the " trawl " and the " towing-net " in searching the upper waters, that, around our own coasts at least, those coveted prizes, "species new to science," are now becoming exceedingly rare ; although it does still happen occasionally that some indefatigable professor has the good fortune to fish one up from the deep, and so to win for himself a niche in the temple of fame as a discoverer in science. In consequence of this rummaging and ransacking of the deep, and, in great part also, in consequence of the unintentional assistance of Old Ocean himself, in flinging upon the shore, during his angry moods, the spoil which has been washed land- wards from far out at sea, we are rapidly extending our acquaint- ance with the life of the waters, and shall probably soon have the means of becoming almost as familiar with the " sea's abun- dant progeny " as we now are with the more accessible inhabit- ants of the upper worlds of earth and air. In so far as it concerns the thousand little creatures which people the shore, nestling in the rock-clefts and tide-pools, the Aquarium and the studies which it has made so popular have done already well-nigh all that could be desired. There is no danger now that they will any longer be passed by in neglect. But there is some reason to fear, that with the enthusiasm that prevails for these " wonders of the shore," others not less interesting, but more seldom seen, will be overlooked and forgotten. On behalf of one of these too much neglected tribes, we now ask for justice justice to the Cephalopods, which have been almost entirely kept out of sight in our popular literature, while other and far less interesting races have been pushed into favour. A Chapter, then, for the CKPHALOPODS, or, in other words, for the Nautilus and its allies. But it will be better, perhaps, to begin with one of our native Cephalopods, by far the most familiar of which is the common THE CUTTLE-FISH. 93 Cuttle-fish. Come with us, then, good reader, down amongst the rocks at low water, where, half concealed by the weeds in some little hollow, we are pretty sure to find a specimen that will suit our purpose. Precisely ; here is the very one we want dead, it is true, but full grown and in capital condition, evidently as yet undiscovered by any of his agreeable but hungry neighbours, who, greatly as they relish a dead Cuttle- fish, have a wholesome dislike of getting too near a living one. Observe, then, that the Cuttle-fish is of a soft, flabby consist- ency, and that its body, o an oval form, is bagged up in a sort of sac* or pouch, something after the manner of those ingenious youths who, tied up in sacks, hop a race, to add to the diversions of a village fair. The Cuttle-fish, however, has this advantage, you perceive, that its arms, or, as they are technically termed, its feet, are ten in number, and quite free; and that, oddly enough, they are arranged in a circle around the top of the head ; thus accounting for the designation of the class as the Cephalopods, or, more properly, the Cephalopoda, which in plain vernacular is simply foot-headed. Turn these arms apart, and two things will be noticed that the mouth of the Cuttle-fish, which is armed with a pair of powerful jaws, shaped like the beak ot a parrot, occupies the centre of the circle formed by the junction of the arras, and that the arms themselves are covered on their inner side with a multitude of little circular discs, slightly raised above the surrounding surface. The eyes, you perceive, are large and prominent, and, though somewhat dull just now, and of a " lacklustre" appearance, had the Cuttle-fish been alive and in the water, instead of lying dead upon the beach, they would have been bright and staring, and expressive of some considerable degree of intelligence. Such, on a hasty glance, is the Cuttle-fish ; and in the main, and allowing for un- important deviations from this the common type of the class, and especially for the shell with which some of the species are protected, such are all the Cephalopods. Examine the Cuttle-fish a little more carefully, however, and many curious details of structure are perceived, which, on a mere cursory inspection are unnoticed. Cease poking it, there- fore, with the point of your parasol or the end of your walking- stick, and stoop down to it, or take it up boldly in your hand. Now press your finger against its back. There is something firm 94 RESPIRATION AND LOCOMOTION. and hard, you perceive, beneath the skin. That is the dorsal plate or gladius of the Cuttle-fish, the well-known " pounce-bone " that you see about on the sand, and in the druggists' shops. If you are not over fastidious, and have a mind to turn dissector for once, your penknife will readily lay open the Cuttle-fish and show you the " bone " in its natural position, where it protects the vital organs, and at the same time serves, by its light and buoyant character, as a sort of float to aid the animal in its vivacious movements in the water. The common Cuttle-fish is the only Cephalopod that has this internal float, although in the common Calamary, or Squid, there is a thin and flexible cartila- ginous plate in the form of a feather, which equally answers the purpose of defence, and also aids in locomotion. Now, look at the mouth of the sack, where the head protrudes, and you will see projecting, just beyond the opening, the end of a tube or pipe, which, if the dissection be proceeded with, will be seen to be the mouth of a funnel-shaped structure, connected, in the interior of the body, with the branchise or breathing organs. These branchiae are lodged in hollow cavities or chambers, and communicate with the surrounding water by valves, through which the fluid is admitted to aerate the blood, by the dilatation of the muscular investment of the body. When, however, the purpose of respiration has been effected, and the water has to be got rid of from the branchial chambers, the valves through which it entered refuse it egress, and it has to be forced out through the funnel smartly or slowly, as the animal may choose. Now, observe : if the Cuttle-fish exerts but little pressure, and ejects the water slowly, all is well the chambers are emptied, again refilled, and respiration goes on without stir or commotion. But if, on the contrary, the muscular investment be suddenly and violently contracted, the water is then made to rush out of the funnel in a violent jet, while the Cuttle-fish, by the mere reaction of the surrounding medium, shoots backward through the water, on the same principle, and with almost as much rapidity, as a rocket mounts into the air. In the same manner all the Cephalo- pods, naked and shell-bearing alike, dart along through the water, repeating the movements at pleasure, with intervals be- tween, or in quick and continued succession ; and thus beauti- fully, by one and the same contrivance, is the double puqxtse effected of respiration and rapid locomotion. Moreover, as these USE OF THE INK-BACf. 95 movements arc made with the head directed backwards, the eyes of the Cephalopod are always turned towards the point from which it darts away, a circumstance which, in times of danger, and when pursued by an enemy, is obviously of great advantage. The ease with which the Cuttle-fish can let go its hold, and dart off from threatened danger, is very well shown by the fol- lowing incident mentioned by Dr. Eoget in his Bridgewater Treatise, Once, when a boy, he tells us, he went out with an old fisherman of Dawlish to visit the floating nets which he had laid for Pilchards. On looking down into the clear blue water, they could easily see that the number of fish entangled was great, but, much to the discomfiture of the fisherman, almost every other Pilchard was locked in the embrace of a Cuttle-fish, plying his parrot-like mandibles to some purpose. The old man, who seemed to regard these unbidden guests as an incarnation of all evil, carried a capacious landing-net, but so quick was the sight of the Cephalopods, so ready were they in letting go, and so agile in darting backwards or sideways, clear of the net, that, though the greedy creattires held on to the last moment, not more than three or four were secured out of the crowds that had spoiled the 'haul. But to come back to our friends on the beach : there is another purpose served by the funnel which we noticed, equally curious with that already referred to. If our dissecting friend were to proceed with his work, and lay open the entire body of the Cuttle-fish, he would come upon a small flask-shaped bag, filled with an inky fluid, and connected by a duct with the funnel afore- said. The use of this ink is very singular. Expert as the Cuttle-fish is in jerking about, and in making off from threatened danger, there are times when he needs have all his wits about him, and exert every means at command to make good his escape. Let us see how he manages. Some hungry Dog-fish, we will suppose, is in hot pursuit. The poor Cephalopod shoots and darts along, but his powerful and ravenous pursuer is rapidly ap- proaching, and in a moment more the monster will be upon him. But just at the nick of time the ink-bag is suddenly compressed, when out through the funnel spirts a jet of the contained fluid, which, mingling with the water in a murky cloud, baffles the pursuer, and gives the Cuttle-fish time to make for the bottom, where he conceals himself, and lies qxiiet till the danger is over. 96 POLYPUS OF THE ANCIENTS. The ink which thus plays such an important part in the economy of the Cephalopods, furnishes the well-known " sepia ' of the artist, while it is also believed to constitute the principal ingredient in the Chinese or Indian ink. It is an interesting fact, too, that in the Belemnite (a fossil Cephalopod allied to the Cuttle-fish, whose remains have been entombed in the solid rock for countless ages), the ink-bag has frequently been found in an almost perfect state of preservation, with the ink itself retaining much of its original character. Dr. Buckland once gave some of this fossilized ink, if we may so term it, to the late Sir Francis Chantrey, requesting him to try its power as a pigment. A drawing was made with a portion of the ink, and shown to a celebrated artist, who immediately pronounced the sepia to be of excellent quality, and begged to know by what colourman it was prepared. But enough about the funnel, and what pertains thereto ; let us look now at the arms of our Cuttle-fish. Observe, then, that two out of the ten arms are much longer than the others, and that, instead of tapering to a point, they are of the same thickness throughout, excepting at the extremity, < where there is a broad flattened expansion, studded on the inner side with similar circular discs to those observed on the other arms. And now examine one of those discs. Look at it at- tentively, for . Stay, though ; there is another Cephalopod to be met with on the shore here, in which we may see these discs to greater advantage than in the Cuttle-fish ; and, as it is now dead low-water, we shall probably find one of them lurking somewhere in the tide-pools, or else prowling among the rocks. Leave the Cuttle-fish to the Crabs, and let us commence the search. Never mind a few drops of salt water, but turn up the clustering sea-weeds, and look into every hole and cranny, for the gentleman ensconces himself in them sometimes. Here, clamber this way, and but look ! there is one of the fellows under that ledge of rock. Sec how he drags himself over the sand, his great arms twining about as he moves along. What eyes ! what a frightful beast ! Jump down, and let me introduce him to you. Octopus vulgaris, ladies and gentlemen : the com- mon Poulpe or Preke, the famous Polypus of the ancients. Now, sir, move this way, and show yourself. We have here, you perceive, a Cephalopod of a different pattern from the Cuttle- STRUCTURE OF SUCKING DISCS. 97 fisli. The body is much smaller in comparison, and almost globular, while the anus arc much longer, only eight in number, all uniform, and united at the base by a thick membrane or web, which greatly aids our friend in his natatory operations. And now turn to the inner face of the arms, and look at- tentively at the discs. Observe that they each consist of a muscular membrane with a thick fleshy circumference, pre- senting when expanded a number of radii converging around the circular orifice of an inner cavity. In this cavity is a movable muscular piston, which, when not in action, is on a level with the circular aperture ; but which, when the disc is closely ap- plied to any object, is drawn strongly back, and the cavity it filled converted into a vacuum ; each separate disc being, in fact, an admirably contrived pneumatic apparatus, which firmly ad- heres, wherever it is applied, on the same principle as a surgeon's cupping-glass or a school-boy's sucker. The purpose of these " suckers " is to act of course as agents in seizing prey ; and of so terrible a character are they, says Professor Jones, that, " armed with these formidable organs, the Poulpe becomes one of the most destructive inhabitants of the sea ; for neither superior strength nor activity, nor even defensive armour, is sufficient to save its victims from the ruthless ferocity of such a foe. A hundred and twenty pair of suckers, more perfect and efficacious than the cupping-glasses of human contrivance, crowd the lower surface of every one of the eight flexible arms. If the Poulpe but touch its prey, it is enough ; once a few of these tenacious suckers get firm hold, the swiftness of the fish is unavailing, as it is soon trammelled on all sides by the firmly-holding ten- tacula, and dragged to the mouth of its destroyer. The shell of the lobster or of the crab is a vain protection for the hard and crooked beak of the Cephalopod easily breaks to pieces the frail armour, and even man himself, while bathing has been entwined by the strong arms of gigantic species, and struggled in vain against a grasp so pertinacious." It is stated by Dr. Roget, that so long as the muscular fibre of the piston is contracted, it is easier to tear away the substance of the animal's arms than to release the suckers from their attach- ment, and that even after the animal is dead, these organs still retain a considerable power of adhesion. We have hitherto spoken of the tentacula of the Cephalophods 98 A TOUGH ENCOUNTER. as arms, although they are eqiially entitled to their technical de- signation of feet, as they serve the animals for crawling along the sea-bottom. All the Cephalopods of the genus Octopus, the Poulpe and its cousins, are especially adapted for this kind of progression, and habitually resort to the sea-shore, where, crawling along in an inverted position, they have a very odd and repulsive appearance. They move along, however, with considerable ease, and progress, it has been ascertained, at the rate of about seven feet in a minute. Should they wish to accelerate their pace, it is said that they inflate the body until it resembles a distended bladder, and, then leaving go their hold, and casting themselves forward, they roll over and over with great velocity, and often effect an escape which would otherwise have been impossible. Let the curious reader, how- ever, beware. It is not always prudent to push matters to an extreme, in trying to induce a display of this odd procedure ; for, as the following adventure abundantly proves, your Cephalopod is apt, at times, to turn crusty, and pursue a totally different course of action. Mr. Beale, in his " Natural History and Fishery of the Sperm Whale," tells us that on one occasion, while searching for shells upon the rocks of the Benin Islands, he came across one of these animals crawling towards the surf which it had only just left. It was creeping on its eight legs, which bent considerably under the weight of its body, and lifted it only a small distance from the rocks. The animal appeared much alarmed, and tried hard to escape. Mr. Beale, however, endeavoured to stop it, and pressed with his foot on one of its legs ; but the strength of the animal was so great that it several times liberated itself, in spite of all the efforts he could employ on the wet and slippery rocks. Mr. Beale then laid hold of one of its tentacles, and held it so firmly, that it appeared as if the limb would be torn asunder between them, He then gave the animal a violent jerk, wishing to disengage it from the rocks to which it clung so forcibly by its suckers. The Cephalopod, however, kept its hold ; but the tug was too much for its temper ; for, the moment after, the appa- rently enraged animal lifted its head, and, letting go the rocks, suddenly sprang upon its assailant's bare arm, and clung to it, with great power, endeavouring to get its beak in a position to bite. Mr. Beale declares that a sensation of horror pervaded his GIGANTIC CEPHALOPODS. 99 frame, when he found that the animal had fixed itself so firmly upon him. He describes its cold slimy grasp as extremely sickening ; and one can well believe him when he says that he loudly called to the captain, who was also searching for shells at some distance, to come to his assistance. The captain, fortu- nately, was soon at hand, and speedily released his companion from the awkward predicament into which he had got himself, by destroying the animal with the boat-knife. The poor Cepha- lopod, however, stuck on to the last, and had to be cut away piece by piece. Our readers, probably will think with Mr. Beale, that this affair was sufficiently horrible ; although it sinks into insigni- ficance beside the frightful stories that are told of these animals by some of the early navigators. Modern naturalists, it is true, make short work of these accounts, and set them all down as fabulous ; though it is admitted that Cephalopods of enormous size do exist. It is notorious, indeed, that the pearl-divers of the Indian seas, and the coral-divers of the Mediterranean, are con- stantly liable to be attacked by these monsters, and that occa- sionally they have been carried off in their arms. The largest Cephalopod of which any remains are preserved in our museums was one obtained during Captain Cook's first voyage in the Southern Pacific Ocean. The dead carcass was found floating on the sea, surrounded by aquatic birds, which were feeding on its remains. Comparing the parts of this animal now existing in the museum of the Royal College of Surgeons with those of smaller perfect animals, Professor Owen estimates that its body must have been, at least, four feet long, and its arms three feet more, making seven feet from the end of the body to the points of the tentacles, a length diminutive, indeed, compared with that as- cribed to the fabulous Kraken of Pontoppidan, but still amply sufficient to render a Cephalopod, with its array of suckers, a truly formidable monster. In systematic zoology, the Cephalopods stand at the head of the Mollusca, and exhibit many interesting points of analogy to the higher or vertebrate division of the animal world. This advance in organization is much more obvious in one section of the Cepha- lopods than in another, but in both alike it is of a very marked and decisive character. Thus all these animals have the rudiments of a true internal skeleton, and there is a perfect symmetry 100 STRUCTURE AND RANK. throughout their animal and vital organs. The muscular system forms a large proportion of the body, with various arrangements and complications unknown in the lower Mollusca. The strong hooked jaws work vertically as in the vertebrate animals, and are accompanied by a thick muscular tongue covered with spines. The respiratory apparatus is enormously developed ; the nervous centres in the head receive a marked increase in bulk, constituting them a tnie brain, which is enclosed in a cartilage, and gives off nervous cords on each side to the organs of vision ; while these, again, arc of an exceedingly complex structure, like those of the vertebrate animals. In the higher Cephalopods there are distinct organs for hearing, and the heart is three- chambered ; while in several of the groups, the external conform- ation of the animals, and many of their habits, bear a strong resemblance to what is observed amongst the superior class of fishes. Professor Owen separates these animals into two great divi- sions, according to the number of their branchiae or gills, and christens them respectively the Dibranchiata and the Tetrar- branchiata the two-gilled and the four-gilled Cephalopods. The two-gilled division takes the highest rank, and includes all the naked Cephalopods, together with the little Argonaut, or Paper Nautilus " The sea-born sailor of his shell canoe," which has ever been such a pet with the poets, aud such a puzzle to the philosophers. The four-gilled branch of the family is represented in our existing seas only by the Pearly Nautilus (Nautilus pompilius), and one other closely-related species these two being now the sole survivors of that multitudinous host of Orthocerarites, Ammonites, Hamites, Baculites, Turrulites, and other allied forms, which swarmed in the ancient ocean, and at one time held the undisputed empire of the seas. It will be but dealing with our subject after the approved " historical " fashion, if, before entering more into detail on the Cephalophods of our own time, we now glance for a brief space at those ancient representatives of the race whose former ex- istence is known to us from the fossilized remains of their shells alone. The Cephalopods were amongst the most numerous and powerful inhabitants of the ancient ocean- It may truly be PETRIFIED SNAKES. 101 said, indeed, that, just as there was an " age of reptiles," and, preceding that, an " age of fish," when these two classes of animal life reigned supreme over the rest of the creation, so, at a still earlier period, there was an Age of Cephalopods, when the sea was peopled with monstrous creatures of this class, and there were either no animals of a higher grade in existence, or only such as were feeble and powerless in comparison with these rapacious monsters of the deep. The whole vast variety of early Cephalopods belonged to the inferior or four-gilled division of the group, and were thus closely related to the Pearly Nautilus of the present day. It is not to be understood, however, that they all resembled the Nautilus in form and figure. On the contrary, there is the utmost diversity of form amongst the shells, though all of them consist of a similar succession of chambers, and were once tenanted by animals agreeing no doubt in all essential particulars with the existing Nautilus. The most abundant of the ancient Cephalopods were those of the different species of Ammonites, so called from the fancied resemblance of their shells to the horns of Jupiter Ammon. In the neighbour- hood of Whitby, the lias rocks abound with these shells, which, varying in size from that of a sixpence to that of the fore-wheel of a coach, are popularly known as " Snake stones," the supposition being that they are veritable petrified snakes. The reader will no doubt recall the passage in " Marmion," in which Sir Walter Scott puts a legend to this effect into the mouths of the Whitby nuns, who tell their " stranger sisters :" " How, of thousand snakes, each one Was changed into a coil of stone, When holy Hilda prayed ; Themselves, within their holy bound, Their stony folds had often found." It so happens, however, that the petrified snakes are always found minus the head, a circumstance which Sir Walter Scott, in the Notes to his poem, satisfactorily accounts for by stating that, at the abbess's intercession, the snakes were " not only petrified but beheaded." The dealers in such wonders not being aware, apparently, of this part of the miracle, and anxious of course to demonstrate the truth of the current story, always contrive to have on hand a few choice specimens of " perfect " snake stones, in which the head of the snake is either formed of 102 CAPTUKE OP A PRIZE. cement and stuck on the shell, or shaped out of the shell itself by means of a file ! In the Museum of the Eoyal College of Surgeons there is preserved the solitary specimen of the animal of the Pearly Nautilus which the country can boast, and which enabled Pro- fessor Owen to prepare the admirable "Memoir" on the species, which gives the only recent and certain information we have of the organization of this interesting Cephalopod. It was taken in 1829, in a bay on the south-west coast of the Island of Erro- manga, in the South Seas, " where," says Dr. George Bennett, who described its capture in his " Wanderings," " it was seen floating on the surface of the water at some distance from the ship. To many it appeared like a small dead tortoise-shell cat, which would have been such an unusual object to be seen in this part of the world, that the boat, which was alongside the ship at the time, was sent for the purpose of ascertaining the nature of the float- ing object. On approaching near it was observed to be the shell- fish commonly known by the name of the Pearly Nautilus. It was captured and brought on board ; but the shell was shattered from having been struck with the boat-hook in capturing it, as the animal was sinking when the boat approached, and had it not been so damaged it would have escaped." The idea of send- ing off a boat to look after a dead cat may appear somewhat absurd, but locality must be taken into account, and the reader who is at all versed in the geographical distribution of animals will know that, thirty years ago, a dead cat in the South Pacific would have been as much a marvel as a dead elephant in South- ampton Water. Nothing very definite appears to be known as to the habits of the Nautilus. It appears to spend its time chiefly at the sea- bottom, where it creeps along with its house upon its back ; occasionally, however, it ascends to the surface and floats upon the water, though, when there, it is totally incapable of directing its course, except by the action of the ordinary respiratory cur- rents expelled through the funnel. The shell of the Nautilus, banded with alternate stripes of orange and white, and to be seen in every " naturalist's," that is to say, bird-stuffer's window, is an exceedingly complicated and interesting structure, and has given rise to much discussion among scientific men. Externally it presents nothing remark- SHELL OF THE PEARLY NAUTILUS. 103 able in its appearance, and might be mistaken for the domicile of an overgrown snail, only that its sides are considerably flat- tened, and that it is somewhat too artistically finished off at the mouth. Cut into halves, however, and exposed thus in section, it is seen to be divided into a series of chambers, the outermost of which is large and roomy, and contains the body of the Nautilus, whilst the others are occupied only by air, and gradually decrease in size as they approach the inner extremity of the shell. The partitions between the chambers are firm plates of shelly matter, which, as they are continued from the side walls, make every compartment perfectly air-tight, and thus convert the shell into a float, which buoys up the Nautilus in the water. A communi- cation is kept up between the several chambers by means of a membranous tube, termed the sipliunde, which, originating in the body of the Nautilus in the outer chamber, passes through all the partitions in succession, and has been supposed, though apparently without much reason, to be the principal agent actively concerned in that alteration of the specific gravity of the Nautilus, by which it is enabled at will to ascend to the surface from the sea-bottom, or instantly sink again if danger threaten. This ascending and descending in the water is an interesting point in the economy of the Nautilus, and one which has abun- dantly shown that philosophers are not exempt from the common failing of preferring novel and fanciful methods of accounting for unusually curious phenomena, even when familiar and common- place explanations would equally answer the purpose. Thus the most ingenious theories have been propounded to explain the modus operandi of these visits of the Nautilus to the sunlight and back, the siphuncle being in all of them alike credited with the chief share in the transaction. But there is good reason to believe it has little or nothing to do with the matter, and that the change of place is effected by a simple contrivance, which, any day in summer, may be seen illus- trated by another little Mollusc common in almost every roadside ditch in the country. The fact is, that, as Professor Owen has satis- factorily shown, the Nautilus, contracted within its buoyant shell, is so little heavier than its own bulk of water, that by protrud- ing its body beyond the aperture of the shell, and spreading itself abroad so as to displace a greater volume of the fluid, it 104 OCTOPODS AND DECAPODS. reduces its specific gravity considerably below that of the sur- rounding medium, and is able to mount almost without an effort to the surface ; while, when there, the mere act of with- drawing itself within the shell will instantly suffice to send it again to the bottom. It is not necessary, therefore, to suppose that the siphon is in any way concerned in these movements ; and in the absence of proof, all theorizing based on the assumption that it is so is a mere gratuitous exercise of ingenuity. By far the most proba- ble function of the tube is, that it helps to maintain the vitality of those portions of the shell which are furthest removed from the body of the animal, and which, if deprived of all vital con- nection with it, would speedily become fractured, and thus totally destroy the hydrostatic balance of the Nautilus, and doom it for ever after to remain at the sea-bottom. The two-gilled Cephalopods comprise the Octopods, distin- guished by the possession of eight arms or feet, and the Deca- pods, which boast the possession of an additional pair of those organs. Let us glance at the ten-armed gentlemen first. In all these animals two of the ten arms are greatly prolonged, and provided at the extremity with a thick fleshy expansion covered with suckers, and, in one family, with powerful hooked claws, for holding on firmly to their slippery prey. The Common Cuttle- fish may be taken as the type of this division of the Cephalopods, which also includes the Calamaries or Squids, the Spirula, and that engaging little fellow, the smallest of the Cephalopods, the common Sepiola. In many of these animals we meet with the rudiments of an internal shell, as in the " bone " of the Cuttle- fish, and the "pen" of the common Calamary, while in the Spirula there is a true chambered shell, though only partially en- closed in the body. The Cephalopods of this section are fur- nished along each side of the body with a powerful muscular fin, which greatly aids them in their movements through the water ; and, in some of the Calamaries, these lateral fins are so largely de- veloped that the animals can project themselves above the surface of the water, and, like the flying-fish, dart for a short distance through the air. Immense numbers of these " Flying Squid '' annually visit the shores of Newfoundland, where they form the principal bait employed in the Cod-fishery. A PET CEPIIALOrOD. 105 Do any of our readers know the little Sepiola ? It will be no disrespect to our readers to assume that not one in ten of them know anything about it. The fact is, this engaging little crea- ture, although by no means uncommon around our southern coast, was all but unknown, excepting by name, even to na- turalists themselves, until Mr. Gosse fished it up from Wey- mouth Bay, and gave us that most entertaining account of its habits in his book on the " Aquarium." Hardly an inch in length, with an almost globular body furnished with prominent fins, the Sepiole is described as a sprightly and beautiful little creature, altogether unlike what one would expect in a genuine Cephalopod. It darts about in the aquarium with the greatest vivacity and grace, and occasionally poises itself in mid-water, hovering like a Moth over a flower. As a general rule, it keeps its two long tentacula coiled up out of sight between its shorter arms, but the little Cephalopod can shoot them out to their full length when occasion requires, and make good use of them too, as Mr. Gosse once had proof one of his little pets having seized hold, with these organs, of a poor shrimp, on which the tiny beak was soon seen busily at work. But perhaps the most interesting circumstance connected with the Sepiole is the singular manner in which it perpetually changes its colour; and, as this property is common more or less to all the Cephalopods, we will give in full the passage in which Mr. Gosse refers to it. It is almost impossible, -it seems, to name any definite colour as that proper to the animal. " Now it is nearly white or pellucid, with a faint band of brown specks along the back, through which the internal viscera glisten like silver. In an instant the specks become spots that come and go, and change their dimensions and their forms, and appear and disappear momentarily. The whole body arms, fins, and all the parts which before appeared free, display the spots, which, when looked at attentively, are seen to play about in the most singular manner, having the appearance of a coloured fluid injected with constantly varying force into cavities in the substance of the skin of ever-changing dimensions. Now the spots become rings, like the markings of a panther's skin ; and, as the little creature moves slightly, either side beneath the fins is seen to glow with metallic lustre, like that of gold-leaf seen through horn. Again, 106 PLINY ON THE POULPE. the rings unite and coalesce, and form a beautiful netted pattern of brown, which colour increasing, leaves the interspaces a series of white spots in the rich dark ground. . . . But here is a change ! One is hovering in quiescence, his colour pale, almost white : one of his fellows shoots along, just over him ; with the quickness of thought the alarmed creature turns from white to a uniform deep brown, the rich full colour suffusing the skin in a second, like a blush on a young maiden's face." There can be but little doubt that the power with which the Cephalopoda are endowed, of thus incessantly changing their colour, is designed to serve as an additional means of protection against discovery. The larger species, indeed, are commonly observed to harmonize their colour to that of the surface over which they pass, so as to render their detection at a short distance a matter of some difficulty. Octopus vulyaris, the common Poulpe, already introduced to our readers, is the model Cephalopod of the eight-armed group. This animal has been famous from the earliest ages, and the most marvellous stories are told of its habits. Pliny has a long account of its various accomplishments, and amongst other things, credits it with "keeping of house and maintaining a familie," for whose behoof it is said to carry home to its nest all that it can take ; and, he goes on to say, that, " when they have eaten the meat of the fishes, they throw the empty shels out of dores, and lie as it were in ambuscado behind, to watch and catch fishes that swimme thither." He says it is a " meere tale, that they gnaw and eat their own clees and arms ; for they be the congres that do them that shrewd turn ; but true it is, that they will grow againe like as the taile of snakes, adders, and lizards." But the best thing he gives us is a story of our friend's partiality for cockles, which is so particularly good that, he tells us, he "cannot ouerpasse " it. "They are most desirous and greedie of cockles, muscles, and such like shel fishes : and they, againe, on the contrarie side, so soone as they feele themselues touched of the Polypes, shut their shels hard and therwith cut asunder their clawes or armes that were gotten within : and thus fall they to feed vpon those who sought to make a prey of them. These Polypi, foreseeing all this, lie in wait to spie when the said cockles, &c., gape wide open, and put in a little stone between the shels, but yet beside the flesh and bodie of the fish, THE LITTLE ARGONAUT. 107 for feare lest if it touched and felt it, she wcmld cast it forth again : thus they theeue, without all daunger, aiid in securitie get out the fleshie substance of the meat to deuoure it ; the poore cockles draw their shels together for to claspe them between (as is aboue said) but all in vaine, for by reeson of a wedg between, they will not meet close nor come neere together." To which story he adds the sage reflection, " See how subtile and craftie in this point these creatures be, which otherwise are most sottish and senselesse." By far the most interesting of all the Cephalopods is the little Argonaut, improperly called the Paper Nautilus. This famous little creature has come down to us from antiquity, stigmatized on the one hand as a pirate and usurper that has no right to the shell it inhabits, and lauded, on the other, as an active and skilful voyageur, and the first instructor of mankind in the art of navigation. Both these matters have been thoroughly investi- gated of late years, and on neither of them now is there the slightest doubt remaining. As the character of the little fa- vourite is involved in the former point, we will examine into that first. Is the Argonaut a pirate? The point has been a disputed one from the time of_Aristotle downwards, although the majority of voices has always been with the " ayes ;" the assumption being that the Argonaut picks up its shell at the sea bottom, and appropriates it to his own use, just as that crusty little oddity, the hermit-crab, is known to appropriate the shells of the common whelk. But on what ground was the assumption made? What is the evidence? In the first place, then, the Argonaut is in no way attached to the shell it inhabits, and has often been seen, when alive, to quit the shell of its own accord. Again, it was alleged, that the position of the animal in the shell is by no means regular and constant, the head being sometimes turned towards one extremity of the shell, and sometimes towards the other a circumstance which certainly seemed to show that the shell was not expressly fitted to its occupant. Further, the body of the Argonaut is just as deeply coloured as that of the naked Cephalopods, which would seem to show that it was not permanently covered from 108 A LONG DISPUTE. the light. In the last place, the eight-armed Cephalopods were known to be a set of prying, inquisitive fellows, fond of poking their tails into every hole and crevice where they could, by any possibility, manage to squeeze them ; and, on one occasion, one of them was actually taken with its body wedged into a small butter-jar, in which it had, no doubt, gone proudly careering through the water, till at last, attracted by the tempting appearance of a baited hook, it ventured a nibble, and so got caught. Evidently the case of the Argonaut was a suspicious one. What had its friends to say on the other side, and to show that the shell it occupied was really of its own fabrication? Two things, and two only they could advance : first, that the shell had never been found on any other animal ; secondly, that the Argonaut had never been found in any other shell. The defence was a meagre one certainly, but it was to the purpose ; and, notwithstanding that the general voice went against it, the Argonaut had many champions on its side, who stoutly main- tained that it was both architect and rightful owner of the grace- ful little bark in which, by general consent, it sailed so proudly on the bosom of the deep. Thus had the question stood for centuries, no new facts of any moment being added, and the disputation going on as stoutly as ever, when at length, and only a few years ago, a lady entered the field, and, by a few simple experiments and observations, put the philosophers to open shame, and for ever set at rest the long- disputed question. Madame Jeannette Power, a French lady residing on the shores of the Bay of Messina, where the Argonaut is of frequent occurrence, enclosed several of the animals in a sort of cage, fenced off from the sea at the water-side, and there studied their history in all its stages. In this way Madame Power ascertained that the Argonaut is the indisputable fabricator of the shell it inhabits ; that the shell regularly increases with the growth of the animal; and that its first formation, and all subsequent repairs that it may need, are effected by the broad membraneous expansions which the Argonaut was reputed to hoist as sails to catch the breeze. The results of Madame Power's investigations came upon the scientific world as a perfect surprisal ; and, in DOUBLE JUSTICE. 109 1839, the lady put the cap of completeness on her labours, by forwarding to the principal learned societies of Europe sets of specimens of the Argonaut and its shell of all sizes ; hoping, no doubt, to teach the disputatious philosophers how much better than theory or argument is a little patient watching and pains- taking examination of actual facts. It was enough for a kdy to do, to clear the character of the Argonaut, and to establish its title to the shell in which it had won such renown as a navigator. It would have been an unseemly thing for those fair hands to have stripped the little Cephalopod of its laurels ; and Madame Power was content to believe with the rest of mankind, that, far out at sea, as the poet sang, the Argonaut " Put out a tier of oars on either side, Spread to the wafting breeze a twofold sail, And mounted up and glided down the billow In happy freedom, pleased to feel the air, And wander in the luxury of light." But there was double justice to be done. The Argonaut had been proved innocent of piracy, and now, by the same stern rule of right, it was to lose its reputation as a sailor. Nearly at the same time as Madame Power was attending to her little proteges in the Bay of Messina, M. Sander Piang was carrying on a somewhat similar course of observations on the opposite shores of the Mediterranean at Algiers. The researches of this gentleman are entirely corroborative of those of Madame Power as to the secretion of the shell by the so-called sails ; but they go further, and show, beyond all reasonable doubt, that the Argonaut has no such power, as is commonly supposed, of hoisting these expanded membranes to " catch the driving gale," and so to sail along the deep. The little Cephalopod can certainly raise itself from below, and sport about at the surface of the water, but it does this with its membraneous flaps closely wrapped about its shell, and by precisely the same means as the Cephalopods in general namely, by the forcible ejection of water from the funnel. M. Rang, therefore, completely upsets the Argonaut's reputation as a sailor ; but, then, he makes him known to us in a new character that of a crawler at the sea- bottom, where, it appears, the animal creeps along with its head 110 COLD PHILOSOPHY. downwards, and its shell upon its back, much after the manner of the common snail. Most terribly true, therefore, is it here, that " All charms fly At the mere touch of cold philosophy." Once we had a little voyageur all elegance and grace " The ocean Mab, the fairy of the sea ;" but " cold philosophy " comes and touches it ; and, lo ! the favourite of the poets becomes a mere commonplace crawler at the sea-bottom. But let us be consoled. Philosophy has revealed more wonders than it has marred ; and, with all deference to the author of " Lamia," prosaic truths are far better than poetic fictions. 1'et.- nf the Aquarium. 1'iinf 111. Ill CHAPTER VI. TEE AQUARIUM AND ITS INMATES. PAET I. " Pellucid pools, and rocks in miniature, With their small fry of fishes, crusted shells, Rich mosses, tree-like sea weeds, sparkling pebbles Enchant the eye a fairy paradise." THE popularity of the Aquarium has considerably abated of late, but a few years since it was something altogether extraordinary. It may be a harsh way of describing this popularity to speak of it as a " mania," but a passion so prevalent and intense is cer- tainly nothing less. The tendency to these peculiar mental epidemics is one of our national weaknesses, and is sure to exhibit itself again and again at longer or shorter intervals. It is no great while ago that it showed itself in connection with those preposterous bipeds, the Cochin-China fowls ; and before we had well become reconciled to those ornithological oddities, a still more virulent craze broke out, for converting plain glass jars into magnificent specimens of porcelain and pottery ware. It was our fair friends more especially who were affected by this latter mania, and so entirely did it get possession of them, that, for awhile, there was nothing that took so amazingly at fancy faii-s and bazaars, nothing that was in such great request for wedding and birthday presents, as choice samples of this home- made mimicry of the costly wares of Sevres and Dresden. But Potichomania, like other manias that had gone before it, speedily ran its course, and had to give way to the stronger attractions of a rival novelty. The narrow-necked jar gave place to the capacious tank ; the corpulent Chinamen, the landscapes with impossible perspective, and the brilliantly-coloured 1 utterflies, birds and flowers, unknown to science, all disappeared before a 112 PRINCIPLE OF AQUARIUM. sudden invasion of Tadpoles, " Tittlebats," and Sea- Anemones ; and Aquarium-keeping became the order of the day. The chemical principles involved in this ingenious and beautiful contrivance are now too well known to require any lengthened ex- planation. It is a matter of familiar knowledge, that in the process of respiration, animals consume the oxygen or life- sustaining prin- ciple of the atmosphere, and give back in return a quantity of carbonic-acid gas, which is as deleterious to animal life as the oxygen is healthful and invigorating. It thus happens that when animals are confined by themselves in a limited quantity of air, this double process of deterioration speedily renders the fluid absolutely poisonous and destructive of life. But in respect to plants, a precisely opposite state of things obtains. By a process somewhat analogous to the respiration of animals, though not to be confounded with it, the vegetable world is continually appropriating the carbonic acid of the atmosphere, and giving back oxygen. In their relation to the atmosphere, therefore, the two great divisions of the organic world beautifully balance one another each taking and appropriating to its own use what would be injurious to the other, and each giving back that which the necessities of the other require. In respect to the free atmosphere this mutually counteractive influence of the animal and vegetable kingdoms has long been familiar ; we owe the Aquarium to the discovery that it equally holds good with respect to the atmospheric air contained in water. The gentleman to whom the world is mainly indebted for this discovery, and for its practical application to natural history purposes, is Mr. Warington, of Apothecaries' Hall, who may fairly claim to be the originator of the Aquarium. But about the same time that Mr. Warington was engaged in his experiments, Mr. Gosse was busily carrying on a similar series, and with the same object in view ; and though not quite so successful as Mr. Warington at first, he was so far satisfied of the practicability of the Aquarium as to suggest the establish- ment of a series of them in the Zoological Gardens, Regent's Park. The suggestion was readily adopted, and early in the summer of 1853 the " Fish House," which for more than twelve months previously had been in preparation, was opened to the public. The success of the novel exhibition was extraordinary. THE AQUARIUM MANIA. 113 All London was eager to look at the wonderful little creatures from the sea-shore ; and, for some months, the Gardens were daily the scene of as much excitement as followed the arrival of that now enormous beast, Obaysh, the Hippopotamus. The publication of Mr. Gosse's elegant volume, " The Aqua- rium," opened up a new source of interest in connection with the subject. It suggested the establishment of the " Parlour Aqua- rium," by means of which private persons might have in their own houses, and under their constant notice, similar collections of animals to those which attracted such attention in places of public resort. The idea was no sooner suggested than it was eagerly caught up, and forthwith the Aquarium was elevated to the first rank amongst the ornaments of the parlour and the drawing-room. The expense, however, was something considerable at first ; and, for a while, it was only in those " desirable residences," as the auctioneers phrase it, the substantial mansions of the people well-to-do in the world, that you had any chance of meeting with the Aquarium. But an increase of dealers, and the competition between them, soon made matters different ; so that before long the man who had only a few shillings to spare could yet have his collection of pet Anemones, and keep, if he would, a whole aquatic menagerie inside his parlour window. Nor did it matter in the least, apparently, where, or at what distance from the coast he might reside ; for like those famous bedsteads one sees announced at the railway stations, the Aquarium, it seems, is expressly adapted to be " sent free by post," and might any- where be had to order by simply addressing a letter to one of the London dealers. In London itself the passion for the Aquarium raged for a while at fever point. The new invention quickly dispossessed the shop windows of all the old-fashioned globes of gold fish, and created such obstructive crowds upon the foot- paths, as to call for a speedy interference of the police. In West- end squares, in trim suburban villas, in crowded city thorough- fares, in the demure houses of little, unfrequented back streets, and inside the flat, sill-less windows of poverty-stricken Spital- fields and Bethnal Green, everywhere you saw the Aquarium in one form or another, and had abundant proof how ardently the cockney of every grade was attached to " the new fancy " which had come into fashion. But it is time that we turn our attention from the history I 114 ZOOPHYTES. of the Aquarium itself to the habits and history of its various inmates the little creatures which all of a sudden became so immensely popular, and which, had they but the gift of speech, might very well say, with a certain bygone celebrity of a higher grade, that they awoke one morning and found themselves famous. One or two words here, however, by way of explanation. It is with the marine Aquarium, exclusively, that we propose to deal : furthermore, we shall refer not merely to those animals, which, with proper care and attention may be permanently domesticated, but occasionally also to those more delicate races, which, excepting under the most favourable circumstances, are to be regarded rather as casual and temporary occupants, than as regular and settled inmates of the establishment. Let us begin with one of these " casual and temporary " races, the most characteristic of the so-called " zoophytes." The little Hydra of our ponds and ditches is the fresh-water representative of an extremely interesting class of these animals, known as the Hydroid-Polyps, which are in reality neither more nor less than associated Hydras enclosed in little homy cups, and supported on a branched tree-like structure of the same horny consistence, termed the polypidom or Polyps' house. It is to these creatures that Crabbe alludes in the well-known lines : " Involved in sea-wrack, here you find a race Which science, doubting, knows not whereto place; On shell or stone is dropt the embryo-seed, And quickly vegetates a vital breed." "Science" has long ago settled "where to place" these animals, and has assigned to them a position but a step or two above the very bottom of the animal series. It was long doubted, indeed, whether they could properly be ranked with animals at all ; and the arborescent forms which the polypidom assumes, still leads to their being popularly classed with sea- weeds. Individually, these little creatures are far too insignificant in size to make any figure in the Aquarium, where indeed they can seldom be kept alive for more than a few days, and for even that time only when the water is extremely pure. But they arc abundantly worth all the trouble they cost, for however short a BEAUTY OP APPEARANCE. 115 period they may remain alive; and if inspected through an ordinary lens their beauty becomes at once apparent. The entire structure then has the appearance of a miniature plant, profusely decked with living flowers ; from which circumstance, indeed, it is that one family of these Polyps derive their name of " Sertula- rian," from sertulo, a little nosegay or chaplet of flowers. The tiny Polyps are seen protruding from their cells, with their ten- tacles fully expanded, now rigidly outstretched, and perfectly motionless, and now suddenly bending and twirling about, as they come in contact with some invisible object floating in the water ; and now, perhaps, taking sudden alarm, they disappear, as if by magic, and shrink to the bottom of their cup-like cells. Very beautiful, too, are the cells themselves ; and in days gone by, when the animal nature of these Polyps was first proclaimed by Ellis, it was these cells which the animals occupied that attracted most attention. " As for your pretty little seed-cups or vases," says Hogarth, in writing to Ellis on the subject, " they are a sweet confirmation of the pleasure Nature seems to have in superadding an elegance of form to most of her works wherever you find them. How poor and bungling are all the imitations of art ! When I have the pleasure of seeing you next, we will sit down, nay, kneel down if you will, and admire these things." The number of these Polyps which are sometimes united together in a single polypidom is almost incredible; the occupants of a little feathery tuft attached to the shell of an oyster or a mussel often outnumbering the entire human popu- lation of the largest cities. And every Polyp of the vast multitude has a vital connection with all the rest. It is united at its base to a sort of medullary pith, which runs through the whole extent of the polypidom, and, in reality, connects the entire society into one compound animal, which, althoiigh having an almost infinite number of separate mouths and separate sets of arms to supply them with food, can properly be considered as only a single organism. In one respect, the individual Polyps seem less entitled to the character of independent existences than the blossoms of a plant ; for when one of the number dies and drops out of its little cup the medullary matter at the bottom of the cell speedily buds out afresh, and the vacant cell is soon occupied by a new tenant. 116 WONDERS OF REPRODUCTION. But here, as elsewhere, the crowning wonder pertains to the process of reproduction. In all these Polyps the ordinary mode of increase is by the process of gemmation, the medullary pith continually pushing out new buds of the horny polypidom, which eventually become developed into regular cup-shaped cells, from the bottom of which new Polyps make their appearance. But in several species, at certain seasons of the year, peculiar closed cap- sules of a larger size than the ordinary cells are produced, and in these a pulpy mass is gradually developed into a number of minute ova, which ultimately make their escape as tiny Medusae the eggs of the Polyp thus producing a swarm of indisputable Jelly- fish ! But this is only half the wonder. In process of time these Medusae, themselves produce eggs, from which spring, not young Medusae, but Polyps in every respect identical with the original stock. Thus the Polyps produce Medusae, which again produce Polyps; as in a former chapter we saw that the Medusae produced Polyps, which in due time resolved themselves into Medusae. It is evident, therefore, that the relation between these two classes of apparently most dissimilar forms of life is of the closest and most intimate nature ; nor is it surprising extravagant as the idea may appear at first that many naturalists should regard the class of Polyps, of which we have been speaking, as nothing more than the early immature forms of bona fide Jelly-fish. But marvellous as is the structure and history of these tiny Polyps, they make such an insignificant show in the Aquarium, that by incurious observers they would be passed by as unde- serving of attention. Not so is it, hoAvever, with the Polypes of another order, which are the most conspicuous and attractive objects that the Aquarium contains, and are pre-eminently the pets of the establishment. It would never do, however, to play one's best card thus early in the chapter ; so that merely entering an appearance for them here, we must postpone for a while all that we have to say on those popular beauties, the Sea- Ane- mones. Between fish and Star-fish there is a wider interval in nature than the names alone would indicate. The two races, indeed, have very little in common, and stand, in somewhat analogous positions, at nearly the two opposite extremes of the animal king- STAR-FISH. 117 dom. The non-zoological reader will understand, therefore, that it is only in the sense of that comprehensive phraseology which makes everything "fish" which lives in the sea, that the Star-fish have any connection with the finny tribes. The Star- fish and their allies constitute the spiny-skinned fraternity known as the Ecliinodermata, a designation, however, which, like many more of our scientific terms, only partially applies to the animals which bear it. The common Star-fish (Uraster rubens) may be taken as the type of its race. It is a well-known creature on most parts of our coast, where it passes under a variety of popular names, as Cross-fish, Star-fish, Five-fingers, and the like, and may often be seen clinging to the half-submerged rocks and boulders at the time of low water, or, dead and partially decomposed, mingled with the line of refuse which marks the highest advance of the tide. People who know the Star-fish only in the form of the stiff and dried specimens of a museum, will be surprised to see them in the Aquarium, clambering over the blocks of stone, bending to all the irregularities of the surface, and moving along with considerable facility. Look attentively and you may see how these movements are effected. From the under surface of each ray protrude a host of minute worm-like suckers, which are seen groping and feeling about, extending and contracting themselves, some fastening on to the surface of the stone, others loosening their hold to stretch forward and attach themselves afresh ; the whole acting, the spectator is apt at first to think, without concert or unity of purpose, and yet, more closely observed, all evidently obeying a common impulse, and enabling the animal by their united efforts to draw itself along. By means of these curious organs, the Star-fish mounts the glass sides of its prison-house just as easily as the blocks of stone ; and thus exhibiting itself, the whole of its under surface is exposed, and every movement of the suckers may be watched. The animal has now a very curious appearance. Its mouth is seen in the form of a circular orifice in the centre of the disc from which the rays diverge ; each of these rays is seen to be traversed by a deep groove ; and from alternating rows of minute perforations in these grooves issue the tubular suckers, which form the Star-fish's only organs of locomotion. But locomotion is not the only purpose to which these curious members are applied. They are equally serviceable in the 118 OYSTER-EATING EXTRAORDINARY. capture of prey ; and, fixed to the shell of any luckless crab, hold him with a firmness of grasp, against which his most violent struggles are totally unavailing. Armed with these formidable appendages, it is no wonder that the Star-fish acts the part of a petty tyrant at the sea-bottom, and makes short work of what- ever shell-fish or Crustacea come in its way. Much of its food, indeed, is derived from animal matter which is already dead and decaying ; but it is equally well pleased to kill its own game ; and sometimes seizes upon a passing neighbour, which, despite all its protestations and entreaties, is relentlessly held fast, the rays of the tyrant bending in upon it meanwhile, pressing it nearer and nearer to the fatal mouth, which, dilating for the purpose, soon engulfs the hapless wretch, and irrevocably seals its doom. Amongst fishermen, the Star-fish has the reputation of being extremely fond of oysters ; and it is said that, when it wishes to indulge itself with one of these delicacies, it lies in wait till it sees an oyster gaping, and then adroitly inserting one of its rays between the open valves, literally eats the poor mollusc " out of house and home." Now, there can be no doubt that the Star- fish has a weakness, not merely for oysters, but for shell-fish in general ; though it is equally certain that it does not adopt the above impossible mode of gratifying its predilections. The truth of the matter, however, is even more wonderful than the current fiction. It seems that when inclined for an oyster supper, the Star- fish clasps the mollusc in its arms, and by means, as it is supposed, of some poisonous secretion, speedily reduces it to a state of perfect helplessness, when the valves of the shell gape wide apart. The gourmand now resorts to the very original and ingenious expedient of pouting its stomach out of its mouth and projecting it bodily into the open shell of the oyster, where the digestive apparatus does its work quite as well as in its own proper place. It is no uncommon circumstance to meet with the Star-fish in the vciy act of performing this most extraordinary gastronomic operation ; and occasionally three or four of the animals may be found clustered together about some poor mollusc, whose vitals they are unitedly sucking out, and with which they form a sort of foot-ball, which the waves roll to and fro upon the sand. The name of " Five-fingers," by which the common Star -fish is known, sufficiently indicates that five is the normal number of BRITTLE-STARS AND SAND-STARS. 119 its rays ; and it is a curious circumstance, in connection with the entire fraternity of Echinoderms, that this same number, five, seems, in almost everything, to reign predominant in the details of their organization. It is not unusual, however, to meet with Star-fish having only four or even three rays ; and not long since there was a specimen of Uraster rubens in one of the tanks in the Regent's Park Gardens which had but two rays, and those on exactly opposite sides of the central disc, so as to give the animal a spindle-form. The truth is, the Star-fish and their allies are endowed with the most extraordinary powers of voluntary dis- memberment ; and when they have the misfortune to injure any of their members they very deliberately fling them away, or rather crawl off and leave them behind. But it is only for a time that the Star-fish goes with less than its full complement of members, as new rays speedily sprout out, and, in due time, the animal regains its normal condition. In so far as is known, the habits of all the true Star-fish are pretty much alike, though in form and appearance there is a considerable difference between the various species. One of the most elegant of those found around our own shores is the well-known Sun-star (Solaster papposa), a magnificent fellow, with from twelve to fifteen rays, and which, decked as it is in rich tints of scarlet and purple, has a truly gorgeous appear- ance as it clings to the rocks with the waves curling and playing around it. Brittle-stars and Sand-stars are Star-fish with a difference. These animals are distinguished by the greater length and slenderness of the rays, which, possessing neither groove nor suckers, differ essentially from the corresponding parts of the true Star-fish. When the Fish House in the Zoological Gardens was first opened, several of these odd-looking little creatures were exhibited in one of the tanks, and the singularity of their ap- pearance attracted much attention. It was speedily discovered, however, that they were not of a kind to be successfully treated in the Aquarium, and no new supply has been obtained to take their place. The Brittle-stars are extremely abundant around most parts of our coast, most of the species inhabiting deep water, where they appear to spend an active existence, swimming and crawling about with considerable facility, by means of their elon- gated spiny rays their only organs 01 locomotion. The common 120 VOLUNTARY DISMEMBERMENT. name of these animals is derived from the extraordinary delicacy of their arms, which break away at the slightest touch, so as to render it a difficult matter to procure specimens in a perfect condition. And what adds to the singularity of the matter is, that this mutilation is a perfectly voluntary act ; for it frequently happens that, when these animals are brought up from the deep, they leap and twist about, snapping off their arms piece by piece, sometimes till there is nothing left but the small central disc. Professor Forbes tells us that he once saw a dredge come up completely filled with specimens of the Common Brittle-star (Ophiocoma rosula"), and that, when they were emptied into the boat, they began creeping about in all directions, writhing with the strangest contortions, flinging their anns about in broken fragments, and putting themselves into a variety of snake-like and threatening attitudes. The boatmen, the Professor says, by no means relished the sight, and begged permission to shovel the little fellows overboard, declaring their belief that the " things weren't altogether right!" By far the most famous of these animals for this propensity to voluntary dismemberment, is one of the true Star-fish, an enor- mous fellow nearly two feet in expanse, which bears the most appropriate name of Luidia frangilissima. The graphic pen of Edward Forbes has given us the following racy sketch of the characteristic peculiarity of this prince of Star-fish : " The first time I ever took one of these creatures, I succeeded in getting it into the boat entire. Never having seen one before, and quite unconscious of its suicidal powers, I spread it out on a rowing bench, the better to admire its form and colours. On attempting to remove it for preservation, to my horror and disappointment I found only an assemblage of rejected members. My conserva- tive endeavours were neutralized by its destructive exertions, and it is now badly represented in my cabinet by an armless disc and a discless arm. Next time I went to dredge on the same spot, determined not to be cheated out of a specimen in such a way a second time, I brought with me a bucket of cold fresh water, to which article Star-fishes have a great antipathy. As I expected, a Luidia came up in the dredge, a most gorgeous specimen. As it does not generally break up before it is raised above the surface of the sea, cautiously and anxiously I sank my bucket to a level with the dredge's mouth, and proceeded, SEA-HEDGEHOGS. 121 in the most gentle manner, to introduce Luidia to the purer ele- ment. Whether the cold air was too much for him, or the sight of the bucket too terrific, I know not ; but, in a moment, he pro- ceeded to dissolve his corporation, and, at every mesh of the dredge, his fragments were seen escaping. In despair, I grasped at the largest, and brought up the extremity of an arm with its termi- nating eye, the spinuous eyelid of which opened and closed with something exceedingly like a wink of derision." The most ambitious owner of an Aquarium will hardly be very sanguine of adding Luidia to his stock of " marine stores ;" but, as Mr. Lloyd, the spirited dealer in aquarian objects, has chosen it as his crest, and has thus "fet to his seal" that the thing may be done, it may be that we shall yet succeed in in- ducing the sensitive beauty to make himself at home in our crystal enclosures. If you bend the rays of a Star-fish under the disc, so that the sides may meet, you will form a sort of spherical or orange-shaped box, and see how an ordinary Star-fish is transformed into an Echinus, or Sea-hedgehog, another of the spiny-skinned frater- nity, which belongs to the pets of the Aquarium. Like its namesake of the furze-brake and the hedge-row, the Echinus has its coat thickly beset with prickles, which need be delicately handled, if you would avoid their points. Each of these spines is attached, by a kind of ball and socket-joint, to a little tuber- cle on the shell of the Echinus, and as the whole of them move freely in every direction, they enable the animal to get out of harm's way when it pleases, by burying itself in the sand. They also assist in locomotion ; but for this purpose the Echinus is pro- vided with far more efficient organs in the shape of long tubular suckers, like those of the Star-fish, which issue from minute orifices in the shell, and, extending beyond the spines, enable the Echinus to creep along the shore, or climb the rocks in search of its diminutive crust-covered prey. The spherical box which forms the shell of the Echinus is an exceedingly curious structure. It is made up of an immense multitude of five-sided pieces, arranged in regular rows, five pairs of which are pierced with minute orifices for the protrusion of the delicate worm-like suckers, while the remainder are studded with tubercles for the attachment of the spines. The plates all fit together with the greatest accuracy, and give the shell the appear- 122 A FINAL JOURNEY. ance of being formed of a single piece ; but, notwithstanding this apparent solidity, a delicate formative membrane everywhere intervenes between the edges of the plates, and by the gradual deposition of calcareous particles to their margins, adds to the size of each in a regular and uniform manner. It matters nothing, therefore, to the Echinus that it is shut up for ever in a hard, unyielding stony box, for, in virtue of this simple but beautiful contrivance, by the same means that it adds to its bodily substance, it also pushes apart the shelly plates of its crusty environment, and makes for itself the additional room it requires. There are several species of the Echinus found around our shores, one of the commonest in many parts being the little Purple Egg Urchin (Echinus miliaris), which thrives very well in captivity, and makes an interesting addition to the Aquarium. At large on the sea-shore, it is generally found in holes and crevices of the rocks, not unfrequently taking up its abode in a deserted hole of that rock-boring mollusc, the pholas ; but in the Aquarium it is very fond of covering itself with bits of gravel, which it holds on by means of its suckers, and, thus adorned, it marches about the bottom of the tank. Nothing, in relation to these animals, is more extraordinary than the amount of injury they can sustain without being materially affected thereby. A remarkable instance of this insensibility to mutilation is given by Mr. Patterson, who once cut an Echinus horizontally into two nearly equal parts, for the purpose of examining the intestines and ovaries, which nearly fill the shell. These vital portions of the animal's organization were taken out, and the divided shell was thrown aside ; but, being put into a vessel of sea-water some time afterwards, Mr. Patter- son was not a little surprised to see the two portions of the empty shell put out their suckers and walk about, "apparently as unconcerned as if the loss of intestines and ovaries had been an e very-day occurrence." Let there be no mistake, however. It was a mere piece of bravado on the part of Master Echinus to exert his power of locomotion under such circumstances ; and there can be no doubt, though the fact is not mentioned, that before long the poor fellow got to the end of his journey and walked no more. If we do not mistake, some ancient erudite somewhere declares SEA-CUCUMBERS. 123 that all the manifold productions of the land have their counter parts in those of the mighty deep. In proof, here, we have the tiea-cucumler, which, though, grown upon no hot-bed, and un- recognized in Covent Garden, is yet, if Chinese epicures and needy Neapolitans may be permitted to decide, not unfit to eat The name is not inaptly chosen, for the larger species of these animals the great Sea-cucumber (Cucumaria f random) of our northern coast, for example closely resemble cucumbers in form ; and yet, furnished at one extremity with a gaping mouth, sur- rounded by plumed tentacula which however can be swallowed out of sight at pleasure and dull and disagreeable in colour, they cuuld hardly be mistaken for those cool delicacies, and it would certainly tax the skill of the most accomplished chef do cuisine to make them acceptable to a British palate. No one unversed in the classification of animals would suspect for a moment that these elongated flabby creatures belonged to the class of prickly skins ; and yet it is, unquestionably, with that division of the animal world that they are properly to be ranked. The affinity of these animals to the Echinodermata is to be found, however, not so much in the character of the skin, which is only sparingly furnished with calcareous matter, and never in the form of spines, as in that of the organs of locomotion, which are delicate worm-like suckers, similar to those of the Star-fish and Sea-urchins. In the more typical species of the Sea-cucumbers, moreover, these locomotive suckers are so dis- posed as to divide the body into five longitudinal segments, thus affording another indication of the true affinities of these singular creatures. The Sea-cucumbers, or the Ifolothuricc, as they are termed by the zoologist, are not uncommon around our coasts, and speci- mens of the smaller species may readily be found at the time of extreme low water, attached by their suckers to the under surface of projecting rocks, and blocks of stone. The species most commonly met with in such situations is the Angular Sea- cucumbers (Cucumaria pentactes), which delights in dark crevices and other obscure retreats close to the low-water mark, where it sometimes occurs in considerable numbers. It is extremely variable in colour, ranging from nearly a pure white to dark pur- ple, or black, the same animal assuming a variety of shades in the course of a few months. Of all the Sea-cucumbers this is by 124 EXCESSIVE IRRITABILITY. far the best for the Aquarium, where, with a little care, it will continue to thrive for years and occasionally present its owner with a family of little ones. The common Sea-cucumber (Cu- cumaria communis) is another of our smaller species well adapted for confinement ; although, living for the most part below the tide marks, it is not so easily obtained. It is curious to observe the movements of these animals in the Aquarium, loco- motion being effected partly by means of the tubular sucker- feet, and partly also by the alternate extension and contraction of the body, as in the case of the common earth-worm and its allies. This worm-like mode of progression is characteristic of the Holothurice, and shows, more clearly than anything else, the nearness of their approach to the Articulate animals, which stand next above them in the scale of creation. It is mainly owing to the highly contractile nature of their muscular system, which is so strongly developed and complicated as to enable these animals to alter their form and appearance in the most remarkable manner at pleasure. Thus, while the great Sea-cucumber already men- tioned is only about a foot long in a state of rest, it can quickly elongate itself to a length of nearly three feet, and then, it may be, suddenly contracting, it will puff itself out in the form of a globe, when, taking another whim, it nips itself in at the mid- dle, and quickly becomes an animated hour-glass ! Let no humane observer attempt, however, to provoke a display of this singular propensity ; for your Holothuria far from being " as cool as a cucumber" is hot and irritable to an extraordinary degree, and not unfrequently, on the slightest alarm or provoca- tion, will throw itself into such violent contortions as to burst asunder and discharge the whole of its viscera. " But," face- tiously remarks Professor Rymer Jones, " the most wonderful part of the tale is, that the catastrophe, so grievous to the spectator who witnesses such a tragedy, seems to be of very small importance to the actor, as the creatures seem to get on just as well without any bowels as when possessed of such trifling additions to their economy ; and, what is more, can reproduce them in a most convenient manner, so as again to become furnished with a complete set." It has already been hinted, that the Sea-cucumbers are used in some parts as an article of food. In China they rank as great WORMS OF SEA-SHORE. 125 dainties, and, with sharks' fins, edible birds'-nests, cats, puppies, and similar delicacies, are made into choice dishes, only available to people well-to-do in the world. The great fishing-ground for the trepang, as the animals are termed, is the northern coast of Australia ; and the extent of the traffic, and the annual slaughter of the Holothurice which it involves, may be inferred from the fact, that considerably more than eight thousand hundredweight of trepang annually finds its way to the China market, to gratify the delicate appetites of the celestial epicures. The uninitiated reader would hardly have looked to the Worms as a class of animals at all likely to furnish the Aqua- rium with any of its pets ; and yet it is to that humble and despised race that we owe some of its most interesting occupants. The truth is, the Marine Worms are a far more engaging race than most people are aware of ; although, now that the Aquarium has given them an opportunity of showing themselves, they are rapidly rising in public estimation. A plea, then, on behalf of the Worms of the Sea-shore. Be it understood in the first place, then, that these Marine Annelids form two distinct groups, in one of which the animals are sedentary in their habits, dwelling in tubes of their own con- struction, while in the other they are unprotected by any such convenient domicile, and roam at large in their native haunts, abundantly provided with organs of locomotion. It is to the tube-makers more especially that the worms adapted for the Aquarium belong, although two or three of the more erratic fra- ternity occasionally share their captivity, one of the number being a gorgeous fellow very well known on some parts of our coast as the Sea-mouse ! By far the most attractive of the tube-making worms are those popular favourites, the Serpulas. No less than eight or nine dis- tinct species of these animals are to be found around our shores, and though they all have a certain beauty of their own, it would seem to be a well-understood thing amongst them, that the large and showy species, Contortuplicata, is to take the lead and chief- tainship of the family : for while the rest lie prostrate at its feet, or meekly cling to it for support, attaching their tubes by their entire length to the shell or stone to which they are affixed, this, more ambitious beauty boldly stands erect for full the half of its length, and woos and wins the admiration of all beholders. 126 STRUCTURE OF BREATHING ORGANS. In one of the marine tanks in the Eegent's Park Gardens, there stood for a long time a common glass bottle completely encrusted with the tortuous tubes of various species of Serpula?, but chiefly with those of the one just mentioned ; and when the worms were all protruding, and their brilliant plumes displayed abroad, the bottle presented an extremely curious and beautiful appearance, as though it had been overgrown by some strange ungainly plant of ocean, leafless, but decked with gorgeous flowers. These flower-like expansions are the Serpula's breathing organs, and consist of a series of stiff threads, arranged in the form of a funnel deeply infolded on one side, and beset on their inner sides with a double row of minute bristles like the teeth of a comb. In the centre of this brilliant array of branchial plumes there is a curious stopper-shaped body seated at the end of a long slender stem, which serves the purpose of a trap-door to the Serpula's domestic establishment, and neatly blocks up the entrance when the little worm finds it convenient to retire out of sight. It does this with wonderful celerity, and at the slightest alarm ; for though the Serpulae belong rather to the " still life" of the Aqua- rium, so long as all things remain quiet, let some eager gazer give the vessel but the slightest shock, and, quick as thought, the little beauties start back into their tubes, leaving their would-be admirer in open-mouthed wonder at their sudden disappearance. Notwithstanding that the Large and showy species of Scrpula already named is almost universally regarded as the beauty of the race, we are by no means sure that the quiet, unassuming grace of the little triangular-tubed species (& triquetra) does not entitle it to a higher place in our favour. It is small in size, it is true, and not very gaily coloured, but the rich tints of brown, gray, and ruby with which its branchial plumes are mottled and banded, give it a very elegant appearance when viewed with a lens, while its operculum or stopper is shaped very much like the cup of the well-known toy, the cup and ball. On first looking at a group of these curious Annelids in a well-kept Aquarium, the observer is pretty sure to be struck with the perfect stillness which they maintain, and the idea of a cluster of flowers is instantly sug- gested to the mind. But within a moment or two, in all pro- bability, the long whip-lash extremity of one of the bristles will be seen to give a sudden twitch, then the bristle itself is slowly raised, then another and fnother partakes of the movement, and THE TEREBELLA. 127 presently the entire plume is twisted round in the mouth of the tube, and it will be a wonder if, in a moment after, some slight movement of the observer himself do not send the little worms, quick as lightning, out of sight. Not unfrequently, groups of Serpula? may be found, in which two or three individuals of the larger species have secreted their tubes in a sort of coil, which stands up nearly erect from some stone or shell, while several of the smaller species cling on to them in various positions, like climbing plants attached to the trunk of a tree. We once had a group of this description, in which the central support was formed by three large specimens of 8. contortuplicata lovingly embracing each other, and putting their heads close together at the top, while attached to them, at different points, there were no less than ten individuals of smaller species of Serpulae, and two tube-making worms of another order 5 and we can assure our readers that when the entire group were in good humour, and put out to the full their variously-tinted plumes, they formed a spectacle of rare interest and beauty. It was really nothing less than a bouquet of worms. In another race of tube-making Annelids, closely allied to the Serpulce, the domicile is formed, not by the secretion of lime from the body of the worm, but by a sort of masonry, the worm regularly building up its tube with particles of sand and frag- ments of shell. By far the best known of these worms is the Terebella (Terebella conchilega), which is extremely abundant on sandy shores between the tide marks, and may often be seen in shallow depressions of the surface, waving about its numerous thread-like tentacles, very busily engaged, apparently, in doing nothing. But it is not at all times that the Terebella is thus idle ; and when the business of house-building is on hand, it has to be its own hodman and bricklayer both. Its tentacles, how- ever, are fully equal to the task, for as they are capable of great extension and contraction, and are also provided with an ad- hesive glutinous secretion, the animal is enabled to sweep the sand for building materials for several inches around its burrow, and to bring them home to the mouth of the tube. Here the selected materials are regularly arranged, and attached to the tube, by means of a kind of cement secreted by the worm, and which forms at once the lining of the tube and the matrix in which the fragments of which it is built are embedded. 128 THE TORE AD-HORNED SPIO. Although grains of sand, small pebbles, and shells, or frag- ments of shells, are the materials usually employed in the formation of the tube, the Terebella is by no means indisposed to make use of other substances when they come to hand ; and in one of these tubes now before us, the spine of an echinus, several fragments of sea-weed, and even small portions of wood, have all been worked into the structure. We can say nothing as to the behaviour of the Terebella in the Aquarium, having no experience of it in confinement ; but we have somewhere seen it stated that with care it may be kept alive for a considerable period, and that by skilfully managing the supplying of materials, it may be got to construct its tube in bands of various colours. One of the most minute of these tube-making worms is the little Spio ceticornis, which may be found in abundance on old shells, and is sure to turn up, if looked for, in any long-established Aquarium. It derives its name from the two long thread-like tentacles, which protrude from the mouth of the tube, and are kept in almost constant motion. The Spio is quite of a social turn, and usually occurs in colonies of several individuals ; and when they are all in full play, twirling about their tentacles together, they make quite a commotion on a small scale. These little worms are large enough to be seen in a good light quite plainly with the naked eye, but when viewed through a glass, they have an extremely interesting appearance. The tubes, which stand erect for a good part of their length, are seen to be formed of minute particles of sand and dirt, and terminate in a circular orifice, from which the worms protrude their two long and almost translucent tentacles. The movements of these tentacles are somewhat peculiar ; at one movement they are seen almost erect and but slightly divergent, then one of them suddenly contracts itself with a singular quirk, and makes a flourish at right angles to its fellow, crinkling and twisting in all sorts of curves as it goes ; meanwhile the other tentacle is twitching and jerking itself as it still stands upright, and then, bending down, it joins the first, and the pair sweep through the water together, outstretched to their full extent, when they stand erect again, to twitch and twirl about as before. But what has more particularly interested us in watching the movements of this tiny animal, is the singular power which it AN INVISIBLE RAILWAY. 129 has of bringing home to its mouth the various matters laid hold of by its outstretched tentacles. These organs are endowed with an adhesive property which enables them by mere contact to hold fast minute particles of matter. They may often be seen stretched out to their full length, pulling and straining at some minute object, which they are endeavouring to dislodge ; pre- sently the object gives way, and is seen adhering to the tentacle. But now, strange to say, the object which has thus been torn off is seen quickly travelling along the surface of the still outstretched tentacle towards the mouth of the worm, which is protruded from the tube, and may be seen distinctly to open to receive the expected morsel. It is just as though the surface of the tentacle was furnished with an invisible railroad, trucks and locomotive all complete. But it is not merely for the conveyance of pro- vender that this curious system of traction is of service ; it is equally available for the conveyance of the materials with which the tube is gradually built up, and the attentive observer will often see the little worm bringing home the minute particles of sand and dirt which lie within the sweep of its tentacles, and then, withdrawing within its tube, employing the tips of its tentacles in adjusting the materials in their proper position. The little Spio is minute and altogether unattractive in ap- pearance, but it is extremely hardy, and need never be wanting amongst the inmates of the Aquarium. In every respect a con- trast to this, is the gorgeous Annelid already alluded to, the Sea- mouse (Aphrodita aculeatci), which is the largest of our native worms, being between three and four inches in length, and half as wide as it is long. It is of a flattened oval form, and is covered along the sides on the upper surface with a dense coating of bristles, which are adorned with brilliant iridescent colours, that rival the glowing tints of the Humming-bird. But unfortunately for the Aquarium-keeper the Sea-mouse speedily languishes and dies in confinement, and not only so, it has no idea at all of making the most of itself. Its proper home is in the deep water, and it is no sooner dredged up from its muddy haunts, and honoured with a place in the Aquarium, than it Blinks away into some obscure corner, and there remains apathetic and motionless, without giving one a single glance at its beau- tiful robe of many colours. It is very common on some parts of the coast, and after high winds may constantly he found cast K 130 SEA ACORNS. up by the waves amongst the line of refuse which marks the highest advance of the tide. One of the most insignificant occupants of the Aquarium, but by no means one of the loast interesting, is the little Balanus* the inmate of the small conical shells known as sea-acorns, which oil many parts of our coast thickly stud the rocks and the timbers of our piers and jetties. This little creature can boast of no great beauty, and has nothing to commend it to our attention but its curious movements and its still more curious history. Its thickly clustering shells look like a mere warty excrescence on the objects to which they are attached, and to most sea-side visitors are, no doubt, far better known for their keen and cutting edges than for any more interesting qualities. I3ut let any of these incurious personages, the next time they are down upon the sands or the pebbly beach at low water, take the trouble to pick up one of the many stones, or limpet, or mussel-shells they will find encrusted with sea-acorns, and place it in a vessel of sea-water, and then watch the result. In a minute or two the little shells will be seen to open at the top* and immediately thereafter they are wrapped in a sort of misty obscurity, which will very probably tempt the observer to rub his eyes, under the impression that some temporary dimness has impaired his sight. But let him look steadily, and the secret will be explained. The truth is, the Balani, now in active play, are every moment whisking out from their open shells a bunch of beautiful feathery organs, in form not unlike a tiny half-opened hand, and again withdrawing them out of sight ; and it is this perpetual and rapidly executed movement which, to the un- practised eye, gives the blurred and confused appearance of which we have spoken. It is easy to watch these curious move- ments in the Aquarium, and such are the grace and regularity with which, they are executed, that one turns to the spectacle again and again with ever new delight. And what, pray, may be the object of this singular procedure ? There is a double purpose to be served, good reader. In the first place, this is the mode the Balanus adopts of getting his "breather" respiration being quite as important to him as to his betters ; and next, it is thus that the little fellow gets his food. That feathery apparatus, indeed, is properly the easting- net of the Balanus, and, at every throw, the tiny fisherman HISTORY OF BALANUS. 131 brings home more or less of those invisible atoms of organic matter upon which it feeds. It is in no idle play, therefore, that the Balani are engaged while they thus sweep the water with their feathery plumes : on the contrary, they are doing battle for very life ; and, like many more important people above water, they have to fight hard, or go hungry. The history of the inmate of the acorn-shell is one of the wonders of marine natural history. In the first stage of its existence the Balanus is a totally different being from what it becomes in after life. Instead of being immovably fixed to one spot at the sea-bottom, it roams the waters in perfect freedom, impelled by the action of six pairs of swimming legs, which keep stroke like so many oars, and send it along by a succession of bounds, much after the fashion of the water-flea. At this stage the young Balanus is also provided with eyes, and a large pair of prehensile antenna?, which serve the little rover as a means of attachment to submerged bodies, when, at any time, it wishes to rest for a while from its more active exertions. All through the spring and summer months, myriads of these juve- nile Balani may be found disporting themselves in the water, making the most of their temporary powers of locomotion. In due time, however, the young Balanus selects a permanent resting-place, and driving at it head foremost, sticks fast, at first merely by the antennas, but, before long, a sort of cement, which pours out from those organs, securely glues the animal to its home, and it becomes a fixture for life. The eyes and the antenna?, now no longer needed, are cast aside, the feathery arms receive their full development, the shelly covering is gradually secreted, and the inmate of the acorn-shell attains his majority. In selecting specimens of the Balani for the Aquarium, they should always be taken from situations in which they are never left wholly uncovered by the retiring tide. On many parts of the coast they cover the rocks by myriads far up towards the high- tide level, and are consequently left bare by the sea, and exposed to the air and burning sunshine for several hours daily. This it appears they bear unharmed; but if a cluster which has been thus exposed be placed in the Aquarium, and constantly.immersed in water, they speedily languish and die ; nor will a daily re- moval from the water for a few hours suffice to keep them long in health and activity. On the other hand, specimens taken from 132 PLEASANT SURPRISES. permanent tide-pools or from deep water are very hardy in con- finement, and give no trouble whatever. One may often obtain good specimens on oyster-shells ; and we have now in our pos- session a solitary individual which was procured in that way, and which has now been nearly twelve months at the bottom of a tank, where it still puts forth its beautiful feathery cirrhi with great animation and vigour. Not the least of the many pleasures which the Aquarium affords are the agreeable surprises which continually arise from the discovery of some member or other of the aquatic community which has previously escaped observation. It not unfrequently happens that discoveries of this sort are made by the naked eye, as it ranges casually over the interior of the tank ; juvenile Anemones, Annelids, and Crustaceans often turning up in out-of-the-way crevices and corners, where and when they are least expected. But more commonly it is when carefully searching over the en- closure with a lens, that these unsuspected treasures are brought to light ; and great indeed, sometimes, is the joy with which they are greeted. It was during one of these investigations, lens in hand, that we made our first acquaintance with living forms of the Bryozoa or Moss Corals, and our delight at the beauty of the spectacle which they presented, combined, of course, with the thought that they formed part of our own live stock, was perhaps a little extra- vagant. Our attention was first arrested by a small patch on an old overgrown shell of what looked like white mucor, but which, on being brought nearer and after a while examined more atten- tively, resolved itself into a crowd of minute creatures standing erect, from little nipple-like prominences, each surmounted by a funnel-shaped coronet of tentacles of pearly whiteness and exquisite beauty. Within a smaller space than would be covered by a split pea, some thirty or forty of these elegant polyp-like creatures were crowded together. And their movements were as curious as their appearance was beautiful. Every moment one or more of the number were twitching and starting, now disap- pearing within their cells, and now again protruding, the stiff bristle-like tentacles being closely appressed, until fully pushed out, and then springing apart into the open-funnel form with a sudden start. It was some time before we could make out what our new-found treasures were ; but before long the beauties were MOSS CORALS. 133 identified, and we looked and looked again with increasing plea- sure at our first specimens of Moss Corals. It has been usual, until of late years, to rank these animals with the Hydraform Polyps, to which in external form and ap- pearance they have a strong resemblance ; but more careful re- search has shown that they possess a far higher type of organiza- tion than the Polyps, and that their true affinities are with the great Molluscan sub-kingdom. There is a great diversity in the form and arrangement of the cells of the different species of Bryozoa, although there is but little difference in the form and structure of the animals themselves. In all of them alike there is a complicated and highly elaborate digestive apparatus, to which access is had by a sensitive and contractile gullet, situated at the bottom of the funnel or bell-shaped circle of tentacles. These organs are rigid bristle-like bodies, incapable of contraction, and beset on their inner side with a double row of vibratile cilia, upon the action of which, in producing a vortex in the water, and so bringing it food, the animals depend for their subsistence. It is an extremely interesting sight to watch the behaviour of these tiny creatures when with a pocket lens and a good light you. get them well into view. We will suppose that on the pro- jecting corner of a block of stone, covered with the delicate lace- work of their clustering cells, a hundred or more of the little funnel-shaped circles of tentacles are seen upstretched. A t first sight all seems still and absolutely motionless ; but in a moment you perceive one and another suddenly starting and half closing their tentacles. In a moment more, and with a steadier look you see the floating atoms in the water above whirling and dancing round, and hurrying towards the bottom of the funnel, where the mouth perceptibly dilates to receive them. But not unfrequently atoms unsuitable for food are brought by the ciliary currents as well as acceptable provender ; against these the mouth keeps reso- lutely closed, while the tentacles twitch and start, and make great efforts to shoot them forth out of the way, sometimes struggling quite convulsively in the endeavour, BO as to suggest to the observer that the little creatures are positively in danger of choking. The Mollusca, to which the Bryozoa introduce us, are not, generally speaking, very well adapted for the Aquarium. There are some few species, however, which are extremely useful, and which may be looked upon, indeed, in some sort as the local Board 134 KUDIBRANCHS. of Health, Thus small specimens of the Oyster and Mussel are very serviceable in keeping down the number of the spores of the sea-weed, which float in the water, and upon which theso animals mostly subsist. In the same way the Periwinkles, and the Trochi, or Top Shells, do good service in mowing down the confervoid growth, which coats the glass and obscures all that is passing within. The manner in which the Periwinkle sweeps off this minute vegetation is extremely interesting, and has been compared to the action of the tongue of an ox in licking up the grass, or to that of a mower cutting swathe after swathe as he passes along in the hay-field. The work is by no means cleanly done, however ; and as the little Mollusc moves on, bringing the white disc of his foot over the spot where he has been browsing, the small square patches which have been swept by his tongue are rendered very distinct by their contrast to the surrounding parts that have not been touched. The most curious perhaps of the Molluscs which readily accommodate themselves to the Aqua- rium are the Chitons, which, clad in their coats-of-mail, adhere like so many scales to the blocks of stone, although occasionally they mount the glass sides of the vessel and help the Periwinkles in clearing away the growing crops of confervoid plants. But by far the most attractive of the Mollusca are certain shell- less animals popularly known as "sea-slugs," which, with a little care and attention, may easily be induced to make themselves at home in the Aquarium. To the naturalist these animals are known as the Nudibranchiata, or naked-gilled mollusca, their branchiae, or breathing organs, being open and exposed, arranged symmetrically along the back in tufts, plumes, or variously-shaped papilla?. The common name the Kudibranchs have won for themselves, sufficiently indicates their general form, and their mode of progression ; but let nobody imagine that these " sea- slugs " have anything like the repulsive aspect of their namesakes of our gardens and hedgerows. On the contrary, they are for the most part more delicate and beautiful than words can well "He- scribe, and when seen in a vase or tank of clear water, wandering over the bright-green fronds of the sea-weeds, they call forth ex- pressions of surprise and admiration from the most phlegmatic and imimpassioned of observers.* * The British Nudibranchiata have been made the subject of a splendid monograph by Messrs. Alder and Hancock, and the coloured illustrations of BEHAVIOUR IN CONFINEMENT. 135 The favourite haunts of these beautiful creatures are the weed-covered rocks which are laid bare only at the lowest ebb of the tide ; and in such situations one may occasionally find them quietly at rest amongst the dripping alga?, or actively peram- bulating the rock pools. Here, too, the explorer will often como across the curious coils of spawn which they attach to the rocks, and with which, when kept in confinement, they prettily bedeck the sides of the Aquarium, where, by-the-way, it answers the double purpose, first of ornament, and then of provender for tho Nudibranch's companions in captivity. In most cases the spawn is deposited in a loose coil of delicate gelatinous ribbon, standing upright, and attached by its lower edge. But in some species the ribbon form is substituted by a simple waved thread, one pretty little fellow disposing this thread in tortuous undulations, like a succession of figures of 8 ; while Doris pilosa, one of the " Sea- lemous," and some others, deposit the spawn in the form of a little cup or goblet, as delicate and beautiful as the most exquisite of sea-nymphs could desire. In the Aquarium these animals are frequently observed to mount the blocks of stone, or the glass sides of the vessel, and to launch themselves out upon the surface of the water, where they float bottom upwards, much after the fashion of the common pond snails in our ditches and stagnant pools. Occasionally they vary the performance, and let themselves down from the surface by a delicate and almost invisible thread of mucus, and so suspend themselves in midwater, as the caterpillars of the little bell-moths are seen suspended from the oak-trees in the summer sunshine. If disturbed, however, when suspended in this manner, unlike the little caterpillars, which forthwith begin to twist themselves about, taking in coil after coil of their silken cables, until they have climbed up out of reach of danger, the Nudibranchs at once let go their hold and sink to the bottom. The whole of these delicate creatures appear indeed to be extremely sensitive to external influences, and become agitated and alarmed at the least suspicion of danger. this work are some of the most accurate and beautiful representations ot living beings which have ever been produced ; and yet it is no disparage- ment to say that even these illustrations convey but a very inadequate idea of the transparent delicacy and beauty of the animals themselves. 136 FEROCITY OF DISPOSITION. It would bo a great mistake, however, to suppose that the Nudibranchs are at all distinguished for gentleness or amiability. On the contrary they are rather remarkable, like some favourites of a higher grade, for petulance and irritability ; and in the matter of feeding they are not only carnivorous, but guilty at times of positive cannibalism. One beautiful little Nudibranch (Eolis coronata), common on our northern coasts, is perfectly ferocious in its way ; and it is said that, if a number of them are kept together without food for a short time, they set to and battle with each other in the most truculent fashion. In preparing for the attack, they angrily raise and shake their numerous papillae, and then laying back their horns, as a vicious horse lays back his ears, they dash together, and maul and mutilate each other like tiny beasts of prey. The larger ones, in their tussles with each other, seldom do more than tear from each other's backs the gaily-tinted breathing organs ; but if a large one falls upon a weaker brother, the doom of the latter is sealed, as he is pretty sure to make a meal for his more powerful as- sailant. One of the commonest of the Nudibranchs, and one of the best for the Aquarium, though by no means one of the most elegant, is Eolis papilosa; it is about an inch and a half iii length, and is very lively in its habits, creeping about very quickly over the weeds and stones, and exhibiting a singular predilection for squeezing its delicate body into every crack and crevice it can discover. But let the owner of the little beauty look well to its provender ; for if there be any remissness on that point, you will find papilosa foraging for himself, and in all probability feasting on some pet Anemone, for which kind of fare the entire race of Nudibranchs have a most inconvenient partiality. 137 CHAPTER Vll. THE AQUARIUM AND ITS INMATES. ' Meantime with fuller reach, and stronger swell, Wave after wave advanced ; Each following billow lifted the last foam That trembled on the sand with rainbow-hues. The living flower, that, rooted to the rock, Late from the thinner element, Shrank down within its purple stem to sleep, Now feels the water, and again Awakening, blossoms out All its green anther necks." THAT is no imaginary scene, good reader, but a genuine sketch from nature the picture of an every-day fact in sea-side natural history. The " living flower rooted to the rock," is a Sea- Ane- mone ; and so faithfully is the portrait given, that you can pro- nounce unhesitatingly as to the particular species which sat for the likeness. And it is no wonder that the author of Thalaba was wanned up into poetic fervour at sight of the beauty ; for the owner of those " green anther necks " is one of the loveliest of its lovely race, and many a time has roused people, far more unimpressible than poets are wont to be, to a pitch of temporary enthusiasm. The Actinias, or Sea- Anemones, are the great ornaments of the Aquarium, and have now become such general favourites, that there are comparatively few well-read observant people who have not to some extent made their acquaintance. It is only a few years since, however, that these animals were all but un- known even to the regular habitues of oxir watering-places ; and so little were they understood by naturalists themselves, that our zoological text-books were full of the most ridiculous blun- ders in reference to their habits and economy. The ordinary form of the Anemones is that of a cylinder, 138 SEA-ANEMONES. truncated, as the geometrician would say, at both extremities ; the lower extremity being attached to the rock, while the upper extremity, or disc, is perforated with an orifice which forms the mouth, around which are several concentric circles of tapering tubular tentacles or arms. It is mainly on the form, number, colour, and arrangement of the tentacles, that the more obvious difference between the various species of Sea- Anemones depends ; but the foregoing may be taken as a fair general description of the form and appearance of these animals that is to say when in a contented state of mind, they stand erect and properly display themselves. But it is not at all times that they are thus amiably disposed ; and the beauty which at one time you find spread abroad like some full-blown, flower, at another time will be reduced to half its former size, its tentacles all withdrawn, and the body contracted to a fleshy knob or " button." The Sea-Anemones are no doubt far better known to the majority of sea-side visitors in this closed-up "button" shape, than in the expanded form of a full-blown flower. It is scarcely possible, indeed, for the most incurious of people to walk along the strip of shore, left uncovered by the tide, without noticing here and there on the rocks and boulders small hemispherical patches of what looks like flesh, of a dull red or liver colour, with probably one here and there of a green colour, or mottled with green and red. These are closed-up specimens of the com- mon Smooth Anemone, which perhaps because it is common is dignified with the tremendous name of Actinia mesembryan- themum. If one of these attached to a pebble be gently taken up and placed in a pool of clear water, it will gradually put out its tentacle and show its mouth, in the shape of a long slit bounded by a pair of pursed-up lips, in the centre of the disc. Two minutes' search in the tide-pools near would probably lead to the discovery of several of the animals fully expanded ; and now, if our explorer likes, having seen the button open out into the flower, he may see the opposite phase of the proceeding, namely, the flower contract into the button. One touch of his walking-stick will be enough. Immediately the outspread ten- tacles are withdrawn and the animal shuts himself up in evident displeasure. It is precisely to use Keats's beautiful simile " As though a rose should shut, and be a bud again." SENSITIVE BEAUTIES. 139 The tmtton, indeed, of some varieties of this Anemone have no slight resemblance to the bud of a large flower ; though one of them, the pretty Strawberry Anemone, derives its inviting alias from its fancied resemblance in this contracted form to that most luscious of summer fruits. The rapidity with which many of the Anemones contract on being disturbed is very great, and has the effect in some situations of instantly withdrawing the animals altogether from view. You are searching along the shore, we will suppose, at low water, and, glancing into a little tide-pool at your feet, you see a beautiful star-like flower spread out at the bottom. You stoop to admire it ; and, eager to secure the prize, you reach out your hand ; but before it has well touched the water, the beauty has vanished out of sight, sinking, as if by magic, down beneath the sand or shingle. The truth is, the animal was attached tc the rocky floor of the pool, and had to stretch itself up through the sand at the bottom to reach the surface where you saw it dis- played abroad ; the moment, therefore, that it contracted itself, it sank out of sight ; and had you searched for it at the bottom you would have felt nothing but a little fleshy mass that un- practised fingers would never recognize as the charming Ane- mone of a moment before. Several of the Anemones are in the habit of burying them- selves in the sand in this fashion, not only when at large in their native elements, but also in the Aquarium. This is especially the case with the pretty Cave-dwelling Anemone (Sagartia tro- glodytes) and the huge Thick-horned Anemone (Tealia crassi- cornis), which seem to delight in situations where they can attach themselves at the bottom of a layer of sand, beneath which they can readily shrink out of sight when occasion requires. We have now in our possession five distinct varieties of the Trog (diminutive for troglodytes), which have been attached to the bottom of a vase, beneath a layer of sand nearly three inches thick, for more than twelve months, and without budging a hair's breadth from the spot where they were first placed. The stationary habit of this Anemone may be turned, indeed, to good account by the Aquarium-keeper; for as they readily attach themselves where they are placed, and are very variable in colour, you may regularly " plant" them in your Aquarium, and with the same regard to harmony or contrast of colour, as 140 RESEMBLANCE TO FLOWERS. you plant your dahlias, or the anemones, vegetable namesakes, and thus contrive a very pretty submarine parterre of animal flowers. The resemblance of the fully-expanded Actiniae to flowers is in many cases very striking ; and Dr. Johnston, in his History of British Zoophytes, mentions, as a curious illustration of the fact, that, on one occasion, a bee wandering near a specimen of cras- sicornis, covered merely by a rim of water, was seen to dart straight at the mouth of the animal, evidently mistaking it for a flower. The poor insect soon discovered its mistake, of course, and struggled hard to get free ; but the Anemone kept fast hold of his prisoner, and speedily swallowed him. No doubt insects are sometimes far from discriminating in matters of this sort, and we have ourselves seen a butterfly knocking itself against a shop window in obvious anxiety to get at some gaily-coloured prints of flowers which were exhibited inside. But the resem- blance of crassicornis to a full-blown flower is certainly very great ; and Mr. Gosse is quite justified in accepting for it the name of the Dahlia, by which it has been christened by some of his fair pupils. In size, beauty, and variety of tints it is more than worthy of the name, though it is by no means singular in this respect, the entire race of Anemones having more or less of the same beautiful and flower-like appearance. Let nobody imagine, however, that the Anemones spread abroad their tentacles in vain conceit of their own beauty. It is hunger, not vanity, which prompts the display ; and in the Aquarium one has to be careful with the tit-bits of oyster, or the over-fed beauties will shut up, and turn their backs upon you in sheer indifference. In the matter of feeding, the secret is, a little at a time, and not too often ; your pets will then be almost constantly on the look-out for provender, exhibiting their charms to the greatest advantage. In this condition the animals readily grasp at any small object that may float or fall within reach of the outspread tentacles, and if adapted for food it is immediately drawn towards the mouth, which dilates to receive the expected morsel, and again slowly closes over it. The tentacles have a strongly adhesive power sufficient to retain small objects by mere contact ; but in addition to this the Anemones are possessed of a poisonous property of such potency, that when they choose to put it forth they can easily overpower and retain animals of considerable size. A FATAL MISHAP. 141 The agents concerned in this adhesive and poisonous power are thread-cells of the same general character as those of the jelly-fish, which crowd the tentacles and various parts of the body, where they are accumulated in special organs, and from which they are projected at the will of the animal with lightning- like rapidity. In none of the Anemones are these organs more potent than in the species whose portrait stands at the head of this chapter, the owner of the " green anther necks," AntJiea cereus. One of these beauties is now before us, twitching and twirling about his long snaky arms, attached to the side of an Aquarium, and it is only a few days since that his poisonous powers deprived us of one of the greatest pets of our marine establishment. The victim was a fine hermit-crab which we had incautiously introduced to the vase at the bottom of which Anthea was then seated. Master Pagurus, as is his wont, began restlessly to promenade the en- closure, and once or twice, before the fatal mishap, had been made to wince by a slight touch from the tentacles of Anthea. But, disregarding these gentle admonitions, at length he backed right upon the Anemone. At first his whelk-shell domicile protected him from all injury ; but presently moving a little on one side, and slightly protruding his body, he brought his sensitive under- surface fairly down upon the tentacles of Anthea. No movement of these organs was seen ; but the poor Pagurus had barely ex- posed himself to the attack before he sprang off from the Anemone with a sudden and convulsive start, which left no room to doubt what had happened. The poor fellow at once sidled away to the shelter of an overhanging block of stone, and the next morning he was found there dead. Mr. Gosse gives a still more striking illustration of the venomous power of this lovely Anemone. One day in collecting he dropped a young conger-eel about six inches long, into a jar containing two large Antheas ; and before the fish had reached the bottom of the jar, the tentacles of one of the Anemones were entwined about its head, which was almost instantly dragged to the cavernous mouth, and partially engulfed. The fish was then withdrawn from its assailant by force, and though it had been kept prisoner by the Anemone less than five minutes, it was already flaccid and helpless, and survived its release for only a few moments. 142 FOOD AND FEEDING. In the Aquarium, Antbea is ever a great favourite ; the singu- larity of its form, the sprightliness of its movements, and the delicate beauty of its colouring, all contributing to its popularity. It has, moreover, this additional recommendation, in which it has ' no competitor amongst our native Anemones, that its disc is almost constantly open, and its beautiful pea-green tentacles, tipped with pink, habitually displayed abroad. Notwithstanding the formidable weapons with which the Anemones are armed, it Is by no means certain that they are such rapacious and destructive creatures as they are commonly repre- sented. It is hardly safe, perhaps, to judge of them by their behaviour in the Aquarium; but there they exhibit, for the most part, no disposition to capture living prey, and will even allow themselves to be hustled and robbed with impunity. We have repeatedly seen food taken, literally, out of their mouths by little rascally crabs, scarcely larger even than split peas ; and the only notice the Anemones have taken of the theft has been to shrink down in the sand, or partially shut themselves up, out of the way of their plunderers. On the shore we have often come across them quietly en- gulfing dead and partially decomposed crabs, and we are strongly inclined to suspect that a great part of their food, in a state of nature, is of this description, that is to say, dead animal matter casually floated within their reach. Nothing is more common after returning from a day's hunting than to find that your Anemones have thrown up the claw or shell of a crab in your collecting can ; and from the circumstance that it is generally portions of the animals only which are thus rejected, there is reason to believe that it was in this divided state that it was at first appropriated. Not that the Anemones are at all nice as to the size of the mouthfuls they take, or in anywise disposed to forego a dainty because it may require a little exertion to get possession of it. On the contrary, there are few animals whose " maw '' is pro- portionately more capacious, or who are less averse to testing the capabilities of that part of their structure in accomplishing an object on which they have set their hearts. One of Mr. Gosse's correspondents mentions a crassicornis which bolted a sea-urchin, spines and all, and auo'iier which discharged, as the remains of his evening's meal, a whelk shell and a mass of nereids and MAKING THE BEST OF IT. 143 shrimps, " which," says the writer, "exhaled such a fearful smell as killed all my tank-ful." But those feats are nothing compared to the performance of another Anemone of this species mentioned by Dr. Johnston : " I had once brought to me," he says, " a specimen of Actinia crassicornis, that might have been originally two inches in dia- meter, and that had somehow contrived to swallow a valve of the great scallop (Pecten maximus), of the size of an ordinary saucer. The shell, fixed within the stomach, was so placed as to divide it completely into two halves, so that the body, stretched tensely over, had become thin and flattened like a pancake. All communication between the inferior portion of the stomach and the mouth was of course prevented, yet, instead of emaciating and dying of an atrophy, the animal had availed itself of what undoubtedly had been a very untoward accident, to increase its enjoyment and its chance of double fare. A new mouth, fur- nished with two rows of numerous teotacuk, was opened up on what had been the base, and led to the under stomach ; the individual had, indeed, become a sort of Siamese twin, but with greater intimacy and extent in its union." In the Aquarium, crassicornis seems disposed to put up with almost any sort of fare that is offered to it. A magnificent speci- men which graced one of our tanks for some time made his last meal on a piece of uncooked sole, and a day or two before he ap- propriated the greater part of a small mussel. On one occasion, we tried him with a portion of the tender posterior of a hermit- crab which had been lying dead for two or three days ; but that lie positively and very peremptorily refused. He clutched at it, indeed, at first, and dragged it towards his mouth, which partially opened to receive it ; but by this time it seems the flavour of the morsel had become apparent, and the mouth again closed, shortly afterwards pouting itself up so as to roll the of- fensive object off the disc, the tentacles on one side bending down to expedite its progress. It would appear from this incident that crassicornis, at any rate, is careful not to eat his game too high, however much he may prefer it for a little keeping. Whatever may be the kind of food swallowed, the undigested portions are always thrown up within about twenty-four hours afterwards, covered with a slimy mucus like the white of an egg. Sometimes, indeed, the most delicate morsels are returned within 144 LOCOMOTIVE POWERS. a few minutes after being swallowed, but from what motive it would be difficult to say. The locomotive powers of the Anemones are not great. Many of the species, indeed, remain attached for months together to the spot where they are first placed ; though others are comparatively restless and frequently change their position. This is especially the case with Anthea cereus ; and as this species is very fond of attaching itself to the glass sides of the Aquarium, its movements may easily be watched. It glides along upon its base with a slow and equable motion, in the same manner as a slug or snail, but much more slowly ; occasionally, however, it has been seen to progress by a series of somersaults, employing base and tentacles alternately as a means of attachment. The common Smooth Anemone is also of a vagrant disposition ; and on one occasion a specimen of the Strawberry variety, now in our possession, travelled a distance of more than twelve inches in one night. It is said, moreover, that when this species is confined in a tank iu which there are blocks of stone projecting above the sur- face of the water, it will sometimes climb up high and dry to give itself an airing for a few hours, and then descend again to its proper element no doubt intending by this procedure to compensate itself for the loss of that alternate exposure to air and water, which, more than any other species, it obtains by the regular ebb and flow of the tide. Dianthus is another of the Anemones which at times seems to take a pleasure in exhibiting its powers of locomotion, being on these occasions almost as fond of wandering over the per- pendicular sides of the Aquarium as Anthea cereus. As a general rule, however, dianthus is rather stationary in its habits, first seeking out a good position, and then, as we shall presently find, veiy literally sticking to it. Its most favourite position, perhaps, is high up on the side of the Aquarium, close to the sur- face of the water, where it stretches itself out horizontally, en- joying in its own fashion the luxury of an air bath. We have now in our possession two individuals of this species, which have been seated thus on the sides of a large vase for nearly eight months ; and what is not a little curious, as showing their partiality for being just at the surface of the water, they have two or three times during this period shifted their position up and down as the level of the water has been altered. PIECE-MEAL REPRODUCTION. 145 There is one circumstance, however, in connection with the movements of dianthus which is of a very remarkable character, and which conducts us to another branch of our subject, namely, the reproduction of the Anemones. It frequently happens that, when a large specimen of dianthus has been attached for any length of time to the same spot in the Aquarium, on moving away it leaves small portions of its extended base still adhering to the glass or stone, as though the animal found it easier to tear its body asunder than to remove these portions from the spot to which they had become so firmly rooted. The fragments thus left behind soon contract, become smooth, and spherical or oval in outline, and in the course of a few weeks may be seen each with a well-developed disk sur- rounded with tentacles, transformed, in fact, into perfect though minute Anemones. Occasionally the larger portions which are torn off from the base of the parent animal gradually separate into two pieces, each of which in due time grows up to be a per- fect dianthus. This mode of reproduction has been observed not only in dianthus, but also, on rare occasions, in the beautiful Segartia venusta, or Orange-disked Anemone. The process of reproduction by spontaneous division, of which the above mode of increase is only a phase, obtains more or less amongst all the Anemones. In most cases, however, the divi- sion of the animal is into two parts only, and longitudinally from above downwards ; the separation commencing at the margin of the disk, and gradually extending across and down the column, until the division is complete, when the two portions close, and before long become perfect Anemones. We have oiirselves observed this phenomenon in AntJica cereus though from the expedition with which the business was effected, we missed the first stage of the actual process of separation. The animal was attached to the perpendicular side of a tank, against the light, and with its base towards us, so that we had a most favourable opportunity of witnessing its procedure. Not an hour before the separation of the two portions was nearly completed, the only indication to be seen of the approaching change was an unusual lateral elongation and flattening of the body, the tentacles along the two straightened sides being curled in and bent down to the glass, while the base showed a divergence of the dark con- tents of the internal cavity towards the two extremes of ths 146 A. DISSOLUTION OF PARTNERSHIP elongated body. We had no suspicion of the impending change, and therefore gave but little heed to the animal, notwithstanding the singularity of its appearance. But an hour afterwards the body of the animal was partially separated into two nearly equal semicircular portions, which were connected together by a number of cords, that for the most part were stretched tensely across between the diverging portions. Watching the progress of the change with a lens, these cords were seen to be gradually pulled in by one side or the other, until the only ones remaining were the two which connected the upper and the lower edges of the now widely separated portions of the divided animal ; and on each of these there hung a flaccid and per- fectly helpless tentacle, that on the upper cord being suspended midway between the two severed portions of the animal. Half an hour after this the two portions had become entirely discon- nected from each other. A little later, the smaller of the two detached itself from the glass and dropped to the bottom of the tank, where it lay utterly prostrate and helpless, giving no other indication of life than an occasional slight movement of one of the tentacles. In about two hours, however, it had so far re- covered its strength as to be able to attach itself again to the glass, when it slowly crawled up the vertical side of the vessel, atid took its place near the other half of its former self. The other portion maintained its place on the glass, and eagerly caught at a small piece of whiting that was offered it ; but swallowing was out of the question, for they had divided the original mouth between them ; and after holding the fish for a while it let the prize go, and feebly drooped its tentacles, the perfect picture of an invalid. Before many days had passed the sides of both animals had regularly closed up, and within a fortnight the half mouth had in each case become a very efficient swallowing organ, and the animals ate and grew apace quite as well as before the dissolu- tion of their partnership. It sometimes happens that specimens of diantlms and the com- mon Smooth Anemone are found, in which two mouths, each with ts own set of tentacles, spring from a common body ; a state of things brought about probably by the self-dividing process having been commenced and then permanently stopped short. In still rarer instances the division of the Anemones has been observed to take place horizontally, the upper half of the animal moving FAMILY GROUPS. 147 off and developing a new base, and the lower half forming a new disk and tentacles. Ordinarily, however, the reproduction of the Actinias is carried on by the production of germs, or embryos, which, after being partially developed in the spaces between the stomach and the outer wall of the body, known as the interseptal chambers, are discharged from the mouth, frequently with the undigested re- mains of the food, twenty to thirty young Anemones sometimes appearing thus at a single litter. Sir John Dalyell states that an Anemone which he had in his possession for six years gave birth during that time to two hundred and seventy-six young ones in this manner. It is by no means uncommon to see some old patriarchal dianthus surrounded by a numerous colony of his descendants in various stages of growth, children, grandchildren, and great-grandchildren all clustering closely together, and not unfrequently exhibiting an unmistakable family likeness. In an Aquarium, in which some of the more freely propagating kinds have been kept for a time, numbers of these tiny creatures may be seen attached to the shells and blocks of stone ; and with their thin gelatinous bodies tinged with the faintest indication of the distinctive colour of the species, and their disproportionately long tentacles pertly stretched out, they have an extremely curious appearance. Another mode in which the increase of these animals is effected is that of budding, the young Anemones sprouting out from the sides of the parent in the manner already described in the chapter on Jelly-fish. Most of the Anemones of which we have hitherto spoken are readily to be found by an industrious explorer within the strip of shore laid bare by the ebb of the tide ; dianthus perhaps being the one least likely to be met with, since, for the most part, it is an inhabitant of deep water. But now, in closing our notice of these extraordinary animals, we will introduce to our readers a gentleman which habitually keeps aloof from the shore, in quiet depths, where he can only be reached by the dredge. Sagartia parasitica is one of the largest of our Anemones, and derives its specific name from its habit of attaching itself to the shells inhabited by the Hermit Crab. Occasionally it is found on shells not thus tenanted, and still more rarely on stones ; its proper home, however, is the domicile of Pagttms BernJiardus 148 A CASE OF MUTUAL ATTACHMENT. and it would be a difficult matter to find another such an odd- looking couple. Mr. Gosse, in his beautiful " Actinologia Britaunica," gives the following humorous sketch of the ways of this loving pair, as furnished by one of his correspondents : " The following scene was witnessed by my much lamented friend, Dr. E. Ball. One of the specimens referred to, attached to the shell of a whelk, Buccinum undatum, which had from its appearance been in all probability just deserted by a Pagurus, was placed in a glass Aquarium ; in a short time, the Anemone left the Buccinum and attached itself to the side of the tank ; it next deserted this position and fixed itself on the side of a large stone that filled the centre of the Aquarium. After the lapse of some weeks a Hermit Crab was dropped into the tank. Well, if these Hermits can't live without hiding themselves in the shell of some poor Mollusc, I think it is equally true that they can't live happy until they hide both themselves and their shells in some quiet little hole in the rock-work of an Aquarium, from whence they can look out ; and, thinking that the superimposed stone-work adds vastly to the strength of their fortifications, experience sundry intense feelings of safety. Be this as it may, the Hermit in question was not long ere ho walked up to a little grotto that was in the rock-work of the Aquarium (quite close to Sagartia parasitica), and after a slight survey, to see that all was right, he turned his left shoulder forward, and " backed in ;" then he began to whisk his antenna? and foot-jaws in a dreadful manner, and looked evidently quite content. I suppose this was a state of things the Parasitica perched on the rock above had long been waiting for ; for it was not long in moving its disc over the top of the small whelk, and before the Crab knew where he was, the big Sagartia had pitched his tent on the roof of the Hermit's house. Where the Hermit Crab goes, there goes the Sagartia : a quiet life it led before, a restless one it has to lead now. But doubtless it knows what's best for it." Our friend the Hermit Crab having thus been brought upon the scene, we will now turn to him, and to the very entertaining race to which he belongs. The lowest members of the series .are the little Balani, dis- coursed of in a previous chapter. Next in order to the Balani SHRIMPS AND PRAWNS. 149 amongst the Crustaceans adapted for the Aquarium, come tlie Shrimps and Prawns, which are extremely interesting creatures, and contribute in no small degree to the gaiety aud animation of the pent-up community. Pale and ghostly in appearance, they glide through the water like the dim and shadowy creatures of another world, their beautiful plumed false legs gracefully beating the water as they sweep along. But these animals are as valuable in the Aquarium as they are beautiful. Their incessant movements help not a little to produce that constant motion in the water which is so conducive to the health of the establishment. Much more effective, how- ever, is the service which they render in this respect by hunting out and devouring the minute portions of animal matter that lie concealed amongst the sand and gravel at the bottom. It seems that they are guided to these atoms by their sense of smell, which appears to be remarkably acute. Mr. Warington, indeed, states that when either a Shrimp or Prawn cuts with his antennas the column of water through which a piece of food has fallen to the bottom, it becomes immediately cognizant of the fact, and turns to find it ; and we have ourselves seen this gentleman produce quite an interesting display by merely drop- ping a few morsels of food into the centre of a tank containing a number of Shrimps, the little fellows immediately crowding to the spot, and eagerly catching at the food like a flock of barn- door fowls. But there is a mistake abroad as to the respective predilections of the Crustacean fraternity, in regard to this matter of feeding. It is commonly stated that the Crab feeds on offal, but that is an error, no animal being more particular in his diet. Piather than devour food which is far advanced in decomposition, the Crab would die of starvation. The fishermen know this fact well, and always bait their crab-pots with fresh meat ; while, for the Lobster, the more highly flavoured the bait, the better it is likely to succeed. It may be received indeed as a general rule, that the short-tailed Crustacea are clean feeders, and that the true depurators, or scavengers, of the waters, are the long-tailed section of the class. The common Shrimp (Crangon vulgaris\ for example, is one of the grossest of feeders, and a swarm of them speedily reduces a drowned cat or dog to a skeleton ; a fact which is hardly cal- 150 AN APPETIZING FACT. culated, perhaps, to give rise to any very appetizing reflections on the part of those who think with Pennant that the animal affords the " most delicious " fare of all the Crustacea, and yet useful to be known. People who want to get the skeletons of small birds or other animals perfectly freed from the flesh, fre- quently put them into ants' nests, but the end may be gained just as well by mooring them in the sea where the Shrimps are known to congregate. The naturalists of the Arctic expeditions have frequently profited by the knowledge of this fact, and by placing beneath the ice the specimens of which they wished to have the skeletons preserved, have had them rapidly pre- pared as they desired by the myriads of small Crustacea living there. Whether the sense of hearing is as well developed in these long-tailed Crustaceans as the sense of smell, it is not so easy to determine ; but in their near allies the Lobsters, there is every rea- son to believe that the one sense is fully as acute as the other. Mr. Belt, in his History of the British Crustacea, says that these animals will sometimes throw off their limbs at the report of a cannou, and in a thunderstorm whole cargoes of them have been known, to do the same, to the great detriment of their marketable value. But the best illustration of the fact is that given in the following story of an old fisherman of Govran Haven in Cornwall, a story, however, which it must be confessed has a somewhat apo- cryphal air, though it certainly deserves to be true : One day, going the round of his crab-pots, the man saw a number of young Lobsters swarming together. He watched them for some time without attracting the attention of an old one which, lodged in a hollow of the rock, seemed to be keeping guard over the young ones at play. No sooner, however, did the old Lobster perceive there was danger near, than it rattled its claws together, as if to sound an alarm, and they all fled to their holes ! Intermediate between the long-tailed Crustaceans and those whose caudal extremity is cwr-tailed, there is a group of these animals with tails that are strictly speaking neither long nor short exclusively, and which, therefore, stands christened in the text-books as the Anomura, or irregular tails. Let nobody think meanly of these worthies ; they supply the Aquarium with its most amusing occupants. Oversights and mistakes or practical jokes are hardly likely to THE HERMIT CRAB. 151 occur in the works of Him of whom we speak as the author of Nature, or we might be inclined to suspect that it was to some- thing of that kind that the Hermit Crab owes his peculiar con- formation. In this unfortunate Crustacean the shelly armour which covers as with a coat-of-rnail the claws and the whole of the fore part of the body, is altogether wanting on the extended tail, and the poor Crab, painfully conscious no doubt of his natural defect, resorts to a contrivance of his own to make good the deficiency. His plan is to seek out the empty shell of some defunct Mollusc of convenient size, and into this he thrusts his exposed and most vulnerable posterior, maintaining his hold of the borrowed domicile by means of two or three pairs of rudimentary feet and a pair of terminal clippers. The common Hermit Crab of our own shores (Pagarus Bern- Jiardus) is commonly to be found in the tide-pools at low water, and shuffles away with great agility if an attempt be made to capture it. Not unfrequently, however, instead of making off, it quickly withdraws within its shell, and endeavours to escape detection by " shamming dead." We have already given some of our Aquarium experience of these worthies. There is something exceedingly grotesque and almost human in the expression of these animals, and in their peculiar movements. The way in which they catch at the food that is dropped upon them, and their mode of holding it firmly in one claw while they pull off piece after piece and carry it to the mouth with the other, is so exactly like the procedure of some hungry urchin eating his dinner in the street, that no one can fail to be struck with the resemblance. And then there is the tremendous stir they make at feeding-time, twiddling tho various organs around the mouth at a great rate, and shooting out fragments of the food sometimes to a distance of several inches ; irresistibly reminding one of the wiy faces and the sput- terings of some over-fastidious epicure who has inadvertently offended his palate. A very critical period in the Hermit Crab's history is the time for the important business of house moving ; and though it is tenant at will, yet as the shell it inhabits is incapable of being enlarged to suit its own increasing bulk, the incident is of periodical occurrence. It is always a business attended with a good deal of anxiety to the poor Hermit ; for while it is no easy 152 CHAXGIXG HOUSES. matter at times to find an empty house that will suit, it may so happen that when at length the " neat commodious residence " has been hit upon, a rival claimant appears upon the scene, and there is no alternative but to search further or fight for possession, a contigency which sometimes gives rise to most amusing scenes in the Aquarium. The right of the strongest is fully as much acted upon below water as above ; and amongst the fraternity with which we are now concerned it is the only recognized principle of action. If therefore Master Bernhardus major finds Master Bernardus minor in possession of a domicile of more conve- nient dimensions than his own, he very deliberately proceeds to dislodge his weaker brother from his dwelling, and having accom- plished his object, slips his own tail into the vacant habitation. But when possession has once been obtained, the mere act of changing houses is very easily performed. We were not a little surprised, indeed, the first time we witnessed the proceeding at the agile off-hand style in which the thing was done. It is true there is a good deal to be done in the way of examination before the old shell is cast aside and the new one occupied, and the care which the Hermit takes to be quite sure there is nothing in the new domicile at all calculated to hurt or irritate his tender posterior is extremely amusing. But when at length the gentleman has satisfied himself on that point, he brings the mouth of the new shell into a suitable position by the side of the old one, and planting his large claws one on each side of it, he whisks out his little bagged-up tail from the old shell and pops it into the new one in the twinkling of an eye. The animal literally jumps out of the one shell and into the other ; and no better illustration can be given of its mode of doing it than that of a person placing his hands on the top bar of a gate and springing over. It is not at all times, however, that the Hermit Crab feels at ease in his new house when he has got there, and we have repeatedly seen them within a few minutes after they have taken possession of a new shell, jump back again into the old one, and commence a fresh examination of the too hastily adopted domicile. Mr. Bell conjectures that the Hermit Crab sometimes attacks living Molluscs for the purpose of getting possession of their shells. But Mr. Lewes, in his " Sea-Side Studies," denies the charge, and in an attempted disproof tells a story of a Hermit in his own A CRUSTACEAN MONKKY-CAGE. 153 keeping, which, having ensconced himself in the shell of a whelk still in occupation of its house, but withdrawn out of reach of the Crab's inquisitive claws, suffered himself to be repeatedly ejected from the premises without making any attempt to kill and eat the proper occupier. It is obvious, however, that a single ex- periment of that sort proves nothing to the purpose. The Hermit Crab may very well decline to play the burglar in a glass case in a gentleman's drawing-room, and yet be nothing loth to act the part when left to himself at the sea-bottom. Mr. Lewes attaches too much importance, therefore, to his solitary ex- periment, when on ' the strength of it ' he tells us that Mr. Bell's conjecture " must be erased from all hand-books." But let us be just to the Hermit Crab ; as nobody appears to have actually witnessed the perpetration of the deed, we may charitably hope that, low as Crustacean morals are, Master Bernhardus is really innocent of the villany imputed to him. The little Hairy Porcelain Crab (Porcellana platycheles) is another of the irregular-tailed Crustacea, and forms a true con- necting link between the long tails and the short tails. In its general form and appearance it is altogether Crab-like, although its great hairy nipper claws give it a very distinctive character of its own ; but when you come to examine its structure, you find that, bent in under the broad round carapace, or crust which covers the body, there is a very decided swimming tail, which proclaims its affinity with its long-tailed allies. The habits of this curious little Crab in confinement are extremely interesting, though rather more shy and retiring than one could wish. It is easily preserved, and speedily becomes a favourite. When the Fish House in the Regent's Park Gardens was first established, a bold attempt was made to domesticate repre- sentatives of well-nigh the entire fraternity of Crustaceans. Mr. Mitchell even laid hands on a fine Lobster, which did its best to make itself at home in one of the tanks, where, if we do not mis- take, it passed its days for several months. But the best part of this Crustacean exhibition was a tank in which a motley gather- ing of Crabs of all kinds were confined together, some of the most curious of the number being the long-legged Spider Crabs from deep water. A very monkey-cage was this tank for the drollery of the tricks you saw ; some of the little fellows, like pigmy pugilists, saucily squaring at you close to the glass front, others 154 GAMINS OP THE AQUARIUM. sparring and scuffling with each other, and scrambling over one another's backs, or stepping daintily about like superfine dandies picking their way in a dirty road. Not even the Anemones, then in the first flush of their popularity, attracted more eager at- tention than these strange yet familiar forms, and great was the loss to the Fish House when this feature of the exhibition could no longer be maintained. Amongst the most hardy of the Crustacea, and the best adapted therefore for the Aquarium, are the small Swimming Crabs (Portunidce) which have dilated, oar-like feet, by means of which they are enabled to perform a sort of natatory movement which gives them a very odd appearance. This is best seen at feeding-time, when they pursue each other for the morsels of food, and rush about over the blocks of stone, making the most extraordinary flying or rather swimming leaps, striking out with their feet the while in a very grotesque fashion. These little Crabs are the gamins of the Aquarium, and for cool impudence and clever trickery have no equals. What with their squabbles with one another, and their raids upon the rest of the community, they form a perpetual source of amusement. They rob the Anemones of their food in the most barefaced manner imaginable, taking it out of their very mouths, and even when it has all but disappeared from view. In the winter they very commonly bury themselves in the sand or gravel at the bottom of the tank, usually under some overhanging ledge of stone, and leaving only the front edge of the carapace with the eyes and the ever-jerking antennas above the surface. In this condition they will frequently remain for several days without stirring a limb, although in warm weather they are most troublesomely active. But even during these sluggish seasons a morsel of oyster dropped into the tank will speedily rouse them, for in some way or other they quickly become aware of its presence, and search about until they find it. And then should it so happen that two of them come upon the prize at the same moment, the battle that ensues is something to see such fencing and sparring, and fierce tussles together as would delight the heart of Lord Palmerston himself. One of the most interesting circumstances in the economy of these animals is the periodical moulting or throwing off of the shelly armature in which they are encased. In all the Crustacea alike these moults regularly take place at longer or shorter in- MOULTING. 155 tcrvals, the removal of the old crust being necessary to admit of the growth of the animal. In the early stages of life, when growth is most rapid, the change takes place at intervals of only a few weeks' duration ; but as the animal advances in age, the shell is cast with less and less frequency, and there is reason to believe that after a certain period the moults cease altogether. All parts of the animal immediately expand on being liberated from the old crust, between which and the new one there is always a very perceptible difference in size. The most curious thing in this moulting of the Crustacea is the remarkably perfect condition in which the old crust is thrown off; the covering of every part of the body and its appendages being left whole and entire, so as to give the rejected crust a striking resemblance to the animal itself. In the ordinary Crabs, indeed, no unpractised eye could detect the difference, and the uninitiated observer who finds the empty shells of one of these animals in his Aquarium is pretty sure to look at it regretfully as the dead body of one of his pets ; and very frequently the mistake is not discovered until some hours, or it may be a day or two afterwards, when, to the utter confounding of the owner, the animal which was supposed to be dead and gone is again seen stalking about, a veritable ghost. A similar mistake sometimes occurs with the Hermit Crab ; but in this case, unless there be some other carnivorous inmate of the Aquarium to account for the disappearance of the fleshy tail, the observer is considerably perplexed at the absence of that important part of the Hermit Crab's structure. Our own first acquaintance with the moulting of the Hermit Crab was made under circumstances which rendered this disap- pearance of the body doubly perplexing. There were two Hermit Crabs confined by themselves in a dish ; but they were by no means neighbourly, and seldom met in their walks without having a spar, which sometimes took the form of a regular fight. One morning they both lay dead (as it seemed) at the bottom ol the dish ; and most unaccountably, in both alike, the fleshy body was clean gone. It was the tragedy of the Kilkenny cats over again, with the difference that in this case the tails were the only parts eaten. What could it mean? The mystery was soon ex- plained. There, amongst the weeds, at the side of the dish, were the real Hermit Crabs, still alive, winking and blinking ; and 156 A TAME CONGER. those tailless forms outstretched on the sand were nothing more than the gentlemen's cast-off clothes. But small space now remains in which to speak of the highest class of animals for which the Marine Aquarium is at all adapted, namely, the fishes ; and it is the less necessary that we should dwell upon them, as but few private persons probably will at- tempt their preservation. The Aquarium is not the place for animals of such free and discursive habits as the fish, which require a wider range and the constant stir and motion of the open sea in order to maintain their health and vigour. In the large tanks in the Zoological Gardens, it is true, they are more at home ; and there the Mullet, the Basse, the Flounder, and a variety of other fish have been preserved with great success : a specimen of the Common Conger ( Conger vulgaris) having occu- pied one of the cases for more than seven years. It was only five inches long when first put into the tank ; but it has since then grown to upwards of two feet in length, and has become so far tamed as to come out from its hole to be fed at a signal from the attendant. It is only with wide space and various facilities at command, however, that success like this is attainable. But there are some few species of fish which, from being more restricted in their range than the race generally, are tolerably adapted for aquarian pur- poses, and to these we may briefly refer, premising that of the in-door life of none of them can we speak from our own experience. The most attractive of the number are the Wrasse or Connors, distinguished by their gay and brilliant tints of green, purple, and gold, and by their thick fleshy lips, which, only partially covering the teeth, give the fish a snarling, surly look, like that of certain ungainly curs. The larger Wrasse are rather too bulky for conve nient management in the Aquarium ; but some of the smaller species may be kept without much difficulty, and make a very attractive addition to one's in-door live stock. The best adapted for the purpose perhaps is the little Corkwing or Goldfinney (Crenildbrus cornubicus), which, though rather of a washed-out appearance in comparison with the bright mail of some of its relations, is yet a fish of some beauty, and a very Paul Pry for its inquisitive habits. The Wrasse may often be seen in fine still weather during ebb- PIPE-FISH. 157 tide gliding about over submerged rocks close to the shore, their own bright colours beautifully contrasting with the darker hues of the sea-weed. No fish, however, are a greater source of trouble and annoyance to the inexperienced angler. Let him attempt to fish where the water is but shallow, or place his float only a little too high upon the line, and scarcely does he " throw out," before the bait is taken by some hungry Connor ; which, the moment it feels the hook, darts to the nearest cluster of weeds, and nestling amongst the stems, or wedging itself into some hole or crevice ifl the rock, bids defiance to the young sportsman, who might tug till the crack of doom without inducing the rogue to stir. Loss of gear is the invariable consequence, with sometimes the additional penalty of a broken rod. With practised fisher- men of course these mishaps seldom occur, the Wrasse rarely getting hooked without being brought ashore. They are but little valued however, most anglers pronouncing them unfit for the table a dictum we make bold to cw^radict ; and aver that, when taken in the proper season, and judiciously cooked (an opera- tion, be it remembered, on which very much depends), they form, as Cockney epicures are wont to say, " most excellent good eating." No fish adapted for the Aquarium are more curious and interesting than the Pipe-fish, of which five or six different species are to be met with around our shores. The long attenu- ated body and the projecting snout of these fish give them a very singular appearance, which is, however, admirably in keeping with the eccentricity of their behaviour. When first introduced to the Aquarium they are very wild and troublesome and if the tank is not covered they are by no means unlikely tc jump out and commit suicide. After a while, however, they become reconciled to their confinement, and they are then very entertaining. You are perhaps watching one of them prying about inquisitively amongst the weeds and stones at the bottom of the tank, when all of a sudden, as if tired of his work, he mounts towards the surface, but half way up, stops short, and coiling his long tapering tail once or twice round one of the larger sea-weeds, he supports himself thus in mid-water like a miniature acrobat. Occasionally two of them will very amicably twine their tails together in a sort of lover's knot, and attach- ing themselves side by side, stretch up towards the surface together, remaining for hours in the same posture. 158 PATEKNAL NURSING. But the point of chief interest in connection with these fish, is the extraordinary circumstance that the male undertakes the principal duties of the maternal office. In summer, when the Pipe-fish commence the business of rearing their young, the female fish, instead of depositing her eggs like other fish mothers, transfers them bodily to the guardianship of her partner, and thenceforth has no further care or responsibility of the family. The gentleman Pipe-fish receives the eggs in a sort of marsupial pouch, which runs along the under surface of the loody, and there the precious burden is retained until the young fry are duly hatched and able to take care of themselves. For some time after their birth the young fish regularly resort to the paternal pouch when danger threatens, and Mr. Yarrel says he has been assured by fishermen, that if when the fish are caught the young ones are removed from the parent and placed in the water, they will keep close to the boat, and again enter the pouch if the old fish is held towards them in a favourable position. It has never yet been clearly ascertained how the transference of the ova is effected ; but it is no unusual circumstance at low tides and in shallow water to find these fish seated very amicably in pairs side by side under the shelter of some boulder or pro- jecting ledge of rock, and the probability is that it is on these occasions that the female Pipe-fish makes her partner happy. One of these fish is a sort of special favourite of ours, from the circumstance that many years ago, when a youngster still at school, it brought us in a very sudden and unexpected manner into a position of what we thought most flattering notoriety. It happened in this wise. We were exploring one day fur out among the shallows left bare by an unusually low ebb of tide, when, in a snug little pool, we discovered a pair of odd-looking and, to us, unknown fish, searching among the weeds, sailing from side to side, and evidently intending to remain in present quarters till next flood. But as " The best laid schemes o' mice an' men Gang aft agley," so in this instance it chanced with the scheme of two Pipe-fish, for such they were. Not without some trouble we secured the double prize, and bore it straightway to a distinguished savant we knew, who had often before accepted our living plunder in exchange for NEW OCCUPATION. 15U what we valued far more some of his own deep acquaintance with their habits and economy. Then it was that we first learned the remarkable facts related above, and saw with won- dering eyes the bright orange-coloured ova packed away in triple rows in the pouch of the male fish. Thus we bartered our Pipe-fish, esteeming ourselves richly rewarded by the strange and wonderful history we had had in exchange. But what was our astonishment some months after this, to receive from our sage instructor a handsome little volume he had just published on the natural history of the neighbourhood, in which, when speaking of the Pipe-fish, he referred at length to our gift in a paragraph beginning as follows : " I have a pair of these fish, presented me by my young friend Mr. (and here our name was given at full length, imprint too, and with such a prefix), taken in," &c. &c. It may be a weakness of ours, but from that time forward we always looked upon the little Worm-shaped Pipe-fish as a de- cidedly handsome fellow. One of the most conspicuous results of the popularity of the Aquarium is the impetus it has given to the study of seaside natural history. People have become so pleased with what they have seen of the indoor life of Periwinkles, Prawns, and Sea- Anemones, that they are now bent on cultivating an acquaint- ance with them in their own proper homes, in the rock-clefts and tide-pools along the shore. The consequence is, that quite a new element has been introduced into the occupation of the visitors to our fashionable watering-places. There are the same groups of listless dawdlers along the sands, the same boating parties, donkey-drivers, absorbed readers, and enthusiastic young ladies in rapt admiration of " the deep and dark blue ocean," as of yore ; but, in addition to these, there is now another class of visitors, carefully studious of spring-tides and the exact time of low water, whose talk is of " Trogs " and " Gems," Balani and Serpulce, who affect hobnailed boots, dresses that won't spoil, and collecting baskets stored with jam-pots and wide-mouthed doctors' phials, and whom you may see corning landwards with every advancing tide, wet and soppy, and with a saline odour about them, as though they were themselves but metamorphosed sea-monsters of some sort just advanced to the human form, and now first emerging from the deep. But let no precise, well-dressed individual think to abash 160 MODERN FA TRY -LAND. such collectors of " marine stores " by sidelong glances of affected pity for their weakness. They have been initiated into the mys- teries of the modern fairy-land, and have made the acquaintance of Aphrodita, Eunice, Beroe, and the rest of the sea-nymphs ; and instead of feeling at all ashamed at being seen dabbling amongst the dripping weeds, and groping in the pools and rock- clefts, they only wonder that anybody can still be found indif- ferent to the thousand objects of interest and beauty which there have their home, bearing silent but eloquent testimony to the wisdom and benificence of the great Author of Life. 161 CHAPTER VIII. THE ANCIENT ORDER OF BATRACHIANS. " The swimming-frog, the toad, the tadpole, the wall-newt, and the water." THE Batrachians are not by any means such strangers as some people may imagine. The reader who has forgotten his Greek, or who never had any Greek to forget, may fail to recognize them, but they have amongst them many old familiar faces for all that. Let nobody therefore run away with the notion that this same ancient order is some old, broken-up, dead-and-gone fra- ternity, similar to those illustrious orders of Odd Fellows, Green Foresters, Ancient Druids, and the like, which still find coun- tenance and support amongst the children of men. The idea is altogether beside the mark. The Batrachians do not belong to the human family at all. They are a race, not of men, but of reptiles, the best known members of the order being the "small deer " enumerated above, from that extraordinary list of dainties which the banished Edgar palms off upon his father as his " food for seven long year." No one will dispute that these little fellows are for the most part familiar enough ; and yet how far removed are they from being familiar friends ! The truth is, the Batrachians have but few admirers. They labour under that direst of misfortunes a bad name. Innocent and inoffensive, and doing no small amount of good iu their way, they are yet misrepresented and maligned, their good qualities denied, and bad qualities from which they are wholly exempt, obstinately laid to their charge. There is perhaps hardly another race of creatures in existence which is BO unanimously hated, and hunted to death, as this poor obscure race of reptiles. It matters not that Homer has sung of their exploits, that Aristophanes lias embellished them with his wit, that their history is one of the most wonderful on record, no- 1G2 THE ANCIENT ORDER OF BATKACHIANS. thing avails to overcome the settled antipathy of mankind ; and the Batrachians will probably go on to the end of their days maltreated and maligned, an unoffending but cruelly persecuted race. It generally happens that injustice of this sort brings about its own punishment, and this is certainly the case in reference to the hard measure so undeservedly meted out to the Batra- chians. The world looks down upon them, gives them ill names, affects a sort of horror of them, and does its best to kick them out of sight ; and the consequence is that the world knows next to nothing about them, and thus misses one of the most marvel- lous chapters in the whole range of zoological science. The Ba- trachiophobia is at length giving way in one direction, it is true ; for the Aquarium has made it manifest that the Water-Newts, spite of a long-cherished belief to the contrary, are perfectly harmless little creatures, elegant withal in their appearance, and very engaging in their behaviour. If prejudice did not stand in the way, we should be ready to admit that others of the order were equally deserving of our attention, and that "horrid" and " odious " as they are generally voted, it would be well worth the while of the curious in such matters to inquire into the de- tails of their habits and economy. We propose, then, to put in a plea on behalf of the Frog and fiis friends, and to show cause why the entire fraternity of Batra- chians should henceforth be dealt with in a more humane and considerate fashion. It will be no difficult task to accomplish, nor will it involve us in anything like a dull and disagreeable discourse ; for however repugnant it may be to the notions pre- valent on this side of the English Channel to introduce any of these little fellows upon the dinner-table, there can be no question as to the excellence of the literary piece de resistance they furnish, if only it be concocted with a little artistic discrimination and care. It may be as well, perhaps, to begin by informing such as are disposed to look down upon the Batrachians, that in the estima- tion of some of the first naturalists of the day, these animals are entitled to a considerably higher rank than that to which they are generally supposed to belong. The common idea of course is that they are neither more nor less than reptiles ; the entire group being regarded as one of the " orders " or principal divisions of RANK OF THE BATRACHIANS. 163 that class of animals. The opinion, however, is now very gene- rally entertained that they ought properly to be regarded as con- stituting by themselves a distinct class, equal in relative import- ance to each of the other great classes of the animal world, and occupying an intermediate position between the true reptiles and the inferior class of fishes. If this view of the matter be allowed, our little friend the Frog and his allies will part company with their quondam associates of the reptile tribes, the snakes, the lizards, and the tortoises, and, raised to a higher level, will take their place on terms of equality with the other great divisions of the vertebrate animals. The Batrachians themselves are no doubt sublimely indifferent as to which way the decision may go on this very grave question, and would be but little elated, it may be presumed, should their elevation to the dignity of an in- dependent class be ultimately agreed to by a unanimous vote of all the zoological professors of Christendom. But, for all that, the question is not without its interest to the student of nature ; and as the Batrachians do really stand as candidates for this ele- vated post, they ought certainly to be regarded with becoming deference and respect. But, whatever may be the true style and title of the Batra- chians whether they continue to be regarded as a subordinate group of the reptile class, or be raised to a class by themselves one thing is quite certain, namely, that they do differ very ma- terially from ordinary reptiles, and approximate in many parti- culars to the class of fishes. The group, as a whole, forms a clear and unmistakable transition from the one class to the other. In the lower divisions of it we meet with creatures so completely fish-like in character, that they can be separated from the fishes only by fixing on some point of distinction which is purely arbi- trary in its nature ; and from these questionable forms we ad- vance, step by step, to the higher divisions, the members of which make a close approach to the character of true reptiles. It is obvious therefore that the Batrachians form a strictly interme- diate and transitionary group ; and so completely do they bridge over the difference between the fishes adapted for a purely aquatic life and the true air-breathing land reptiles, that they obliterate* so to speak, all essential distinction between them. If there be any one thing which more than another shows the true character of the Batrachians, it is the remarkable changes 164 DKPOSITION OF SPAWN. they undergo in the early period of their history. The trans- formation of a Tadpole into a Frog exhibits, in the successive phases of the life of an individual animal, substantially the same stages of advancement towards a higher type of organization as are marked by the mature forms of the several members of the group as a whole. It will be interesting therefore to notice by what steps this progressive improvement of structure is made ; and as there is no lack of Tadpoles in our ponds and ditches throughout the spring and fearly part of summer, any of our readers who choose to do so may readily verify our statements for themselves. In the beginning of March, then, the Frogs which all the winter through have been comfortably " conglobulated " together, as Dr. Johnson said of the swallows, in the mud at the bottom of the ponds and ditches, wake up from their protracted sleep, and make their appearance at the surface of the water. In a little while they are all busily engaged in their nuptial rites, with respect to which the only remark we have to make is, that we wish they were somewhat less obtrusively thrust upon our notice. The eggs are deposited in large masses at the bottom of the water ; but as each egg is surrounded by a covering of glutinous matter, which readily absorbs water, the entire mass speedily swells, and becoming lighter than the surrounding medium, it rises to the surface. In this stage the eggs appear as little black dots, separated from each other by a globular investment of transparent colourless jelly ; and it is only by bearing in mind the extraordinary abundance in which this spawn is to be seen in the water in spring, that one can account for the myriads of tiny Frogs to be found hopping about the margins of the ponds later in the year. For about a month or five weeks the eggs gradually increase in size ; at the end of that period the young Frogs as yet, however, far otherwise than Frogs in form burst the en- velopes of the eggs, eat their way through the gelatinous walls that imprison them, and make their escape into the water. In the condition in which the little creature commences its active life, it is known to every village urchin in the land as the Tadpole, or Loggerhead. The Cockney schoolboys give it the more expressive name of Tiddler. The little thing seems all head and tail. " It is provided," says Cuvier, " with a long fleshy tail and a small horny beak, and has no other apparent members HABITS OP TADPOLE. 165 but little fringes at the sides of the neck." These fringes are the Tadpole's breathing organs, and one of the earliest changes it experiences is the shrinking of these organs, and their subse- quent disappearance beneath the skin, where they discharge the functions of the gills of a fish. The mouth of the Tadpole is placed low down in the front of the head, so that when the little fellow wishes to seize anything floating on the surface of the watt., he has to throw himself on his back like a shark ; and so nimbly does he execute this manoeuvre, that the eye cannot with- out difficulty follow it. Thus expert in appropriating food, the tadpole rapidly increases in size, the tail acquires greater breadth, and the limbs slowly make their appearance. The hind feet are developed first, increasing by little and little, and then the fore feet also appear. The beak now falls off and exposes the true jaws, whieh were before soft and concealed under the skin ; the tail is gradually absorbed, and the young Frog begins to assume something like his mature form. In a few days more the little fellow, advanced to the dignity of positive froghood, takes his leave of the water, and stops ashore, thenceforth repudiating the shrivelled remnant of his once ample tail, which is now speedily disposed of after the manner in which Lord Monboddo and his disciples would have us believe that our own quadrumanous pro- genitors disposed of theirs. While these external changes are in progress, modifications of still more importance are taking place in the whole of the internal organization. In the first place, let us look at the development of the spinal column or back-bone. In the newly-hatched Tadpole this part of the structure consists of little more than a simple fibro-cartila- ginous cord. As the little creature grows, this cord begins to ossify, though only in that portion which is to be retained in the future Frog. After the process of ossification has gone on for a short time, the cord becomes converted into a distinct vertebral column ; both faces of the separate vertebra? in this early stage, however, are concave, and between each pair of vertebra there is precisely the same sort of hollow filled with fluid as that which distinguishes the vertebral column of fishes. But ossification proceeds ; and now gradually filling up the hinder cavity of each vertebra, and projecting the newly-formed bone into the front cavity of the vertebra behind, it finally converts the entire series 166 INTERNAL DEVELOPMENT. into a vertebral column, connected throughout by the true ball- and-socket joint characteristic of the higher reptiles. The changes which take place in the circulatory and breathing apparatus are not a whit less remarkable. In the first instance the condition of these organs is in all essential particulars precisely the same as in the class of fishes. Thus the blood, driven from the arterial bulb through the branchial art/^ies, circulates freely through the gills, and is again collected in the branchial veins, of which two pairs unite in forming the great aorta of the body, whilst the other pair is distributed in the head. The pulmonary arteries first make their appearance in a very rudimentary form, springing from the branchial vessels. But as the lungs are developed and aerial respiration commences, these arteries rapidly increase in size, whilst the branchia and their vessels gradually diminish in the same proportion. The change still proceeding, the branches which unite the branchial arteries acquire a much greater development, and gradually divert more and more of the blood from the branchiae, which now speedily disappear altogether, and leave to the pulmonary arteries the task of carrying on the entire business of respiration. In this way the little fish-like Tadpole, adapted exclusively for an aquatic life, gradually becomes metamorphozed into a being possessing every requisite for a strictly terrestrial existence ; though, whether it be from the strength of early associations, or from some more re- condite cause, the Frog seldom wanders far from his original home, and appears his life through to prefer to either land or water, strictly so called, that convenient compromise between the two afforded by the swamp or ditch. The progressive changes related above obtain of course only in the young of the higher grades of Batrachians. In the lower forms the metamorphosis is arrested at various points, so that the mature condition of these animals marks, so to speak, the successive stages in the development of the young of the more advanced members of the order. But there are some rather curious and some truly extraordinary circumstances in connection with the early history of some of these higher members which must be referred to here. In the rst place, there is a Toad common enough throughout the Continent, and well known in the neighbourhood of Paris, which has obtained for itself the name of the Accoucheur Toad (Bufo ACCOUCHEUR FOOD. 167 obstetricans), from a singular habit which, the male has of as- sisting the female in the exclusion of the eggs, which he after- wards attaches to his own hiud-legs, and carries about with him till the young Tadpoles are ready to escape, when he conveys his charge to the water, where henceforward the young make their way in the world just as Tadpoles that are less highly favoured with parental care. Still more extraordinary is the procedure of the monstrous Surinam Toad (Pipa Americana). The eggs of this species are deposited by the female at the margin of the water, and are then carefully collected by the male and deposited upon the back of his partner in a number of singular pits or cells which stud the skin. A single egg is pressed by the male Toad into each of these cells, which are then closed with a sort of lid. The development of the Tadpole proceeds in these confined spaces in exactly the same way as with those of the other Batrachia which roam at large in the water ; and when the young animal has completed its changes, it comes forth at once a perfect Toad. In the Salamanders, again, the early part of the development of the young takes place within the body of the parent. It is not a little singular, too, that in the conversion of the bi-concave into cup-and-ball vertebrae, in the development of the Tadpole of the Salamander, the newly-formed bone fills up and extends from the front cavity, so that in the adult vertebras the ball is anterior and the cup posterior, as in some of the more reptile-like fishes. The Water-Newt, instead of depositing its eggs in patches or masses like the Frog, or in long chains like the common Toad, doubles them up singly in the leaves of aquatic plants. In the young Newts, again, the development of the fore-legs precedes that of the hind pair, while, as we have already stated, the reverse of this takes place in the young Frog, which, by the way, appears from observations communicated to Mr. Patterson of Belfast, to be in the habit of literally " putting its left leg foremost," the left fore-limb being perfectly developed, while the other is still "nowhere." Mr. Bell, in his " History of British Eeptiles," brings a serious charge against the Tadpole of the Frog, accusing it of no less a crime than downright cannibalism ; and what is not a little odd in the matter is, that the horrible propensity is said to manifest itself only when the limbs first make their appearance in any of the Tadpole's companions. Suspecting that this was the case, 168 SHOWERS OF FBOGS. Mr. Bell placed in a large glass globe of water several Tadpoles nearly approaching their final change, and he observed that, as surely as one of them acquired its limbs, it would soon afterwards be found dead at the bottom of the water, and the other Tadpoles feeding upon it. This took place with all of them successively, excepting the last, which not being able, or perhaps disposed, to eat himself, lived to complete his change, and doubtless grew fat upon the rum of his fellows. One of the popular errors which have come down to us from the remotest times, and one which still has vitality enough to secure an occasional paragraph in its support in provincial news- papers, is the belief in showers of Frogs. The origin of this belief is no doubt to be found in the extraordinary abundance in which young Frogs, just after the completion of their transforma- tion from the Tadpole state, and especially after rain, are seen in the act of migrating from the pond or swamp in which they commenced their career, into the surrounding districts. Enor- mous numbers of these tiny creatures are sometimes to be met with in this manner, the ground being at times literally covered with them over a considerable area ; and as this curious spectacle is most frequently observed after heavy showers, accompanied, as such showers occasionally are about the middle of the year, by thunder and lightning, it is not at all extraordinary that the notion should have arisen that the animals in question came from the clouds. Incidental allusions to this idea are to be found in many of the writers of antiquity ; and Aristotle goes so far as to assert that the Frogs so seen are a peculiar sort, which he terms dioTTtTTjs, " sent by Jupiter." In later times, when philosophers were more ambitious of ac- counting for the supposed facts of popular belief than of testing their accuracy, a variety of ingenious reasons were assigned for the phenomenon. The celebrated Cardan, in his book " De Subtili- tate," maintained that it was the violence of the wind which carried the Frogs from the tops of the mountains and bore them to the plains. Another idea was, that the eggs of the Frog were taken up by the winds, and, being hatched in mid-air, the young Frogs fell to the ground ; but against this theory, Scaliger urged very conclusive objections, that the eggs of the Frog produce, not perfectly formed Frogs, but Tadpoles, which no one pretended had ever come down from the clouds. THE DELUSION DISPELLED. 169 Bay, in his "Wisdom of God in Creation," fully discusses tLis " shower of Frogs' " question, and shows how entirely groundless is the common opinion on the subject. But, more than this, he gives us, on the authority of his friend Mr. Derham, an account of one of the said "showers," which clearly shows how the popular notion originated. Mr. Derham relates, that one after- noon, while riding in Berkshire, he came upon an immense multi- tude of minute Frogs crossing the road. There had been a shower of rain only an hour or so before, and he immediately thought of what he had heard of the raining of Frogs. But not being a believer in that sort of thing, he determined to search into the matter. On examining the neighbourhood, he found two or three acres of ground nearly covered with a vast " black regiment," which was proceeding all in one direction towards some woods and ditches at a short distance in front, and which he traced back to a large pond that in spring-time, he ascertained, always abounded with Frogs from which circumstances he very pro- perly concludes that the little wayfarers had come, not from the clouds, but from the pond whence they were marching ; that they had been tempted to set out on their journey by the recent shower, and were going bodily in search of fresh provender. Let us now glance briefly at some of the less familiar forms of the Batrachia, preparatory to giving our attention more at length to the little fellows with whom we are better acquainted. At the very bottom of the series, if in the series at all, and on the very boundary line between the fishes and the Batrachians if such a boundary line be really allowable stands the singular creature first exhibited alive in this country at the Crystal Palace, Sydenham, and now numbered amongst the treasures of the Zoological Gardens as the " Mud-fish " (Lepido&iren annectans). There is a dispute amongst naturalists as to whether the " Mud- fish " should be classed with the fishes or the Batrachians. Dr. Natterer, the discoverer of the animal, regards it as a Batrachian reptile, and in this opinion most of the writers on natural histoiy agree ; but Professor Owen, relying, we believe, chiefly on the peculiar character of the animal's nose, places it amongst the fish. It would be more correct, perhaps, to say placed, for since Professor Owen has had the opportunity of examining the speci- mens recently living in this country, he appears to incline to the opinion that the creature is properly neither fish nor reptile, 170 THE LEPICOSIREN. but something strictly intermediate between the two one, in fact, of those " connecting links " in nature which some people laugh at as mere creations of the fancy. The Lepidosiren is extremely fish-like in appearance, having an elongated tapering body covered with scales, and furnished along the back, and both above and below the tail, with a thin membraneous fin, pre- cisely as in some of our commonest fishes. It differs from fish, however, in the broad flattened head and obtuse muzzle, and still more obviously in being furnished with two pairs of rudi- mentary limbs in the shape of long tapering filaments. Three species of this curious animal are known, all of them being con- fined to the tropical rivers of Africa and America, where, at the approach of the dry season, they bury themselves in the mud at the bottom of the water and remain in a state of torpidity for several months. It was in this condition, enclosed in balls of hardened clay, and cut off from all communication with the ex- ternal air, that three of the animals were brought to this country from the Gambia, and presented to the Crystal Palace Company by Captain Chamberlyne. In the famous Siren (Siren lacertina), an eel-like creature which inhabits the marshy rice-grounds of Carolina, and several allied forms, a single pair of limbs only is developed, and in addition to true lungs for aerial respiration, they are furnished throughout the entire period of their existence with external tufted gills for respiration in the water. No wonder, therefore, that for a long time these animals were regarded as Tadpoles of higher forms of Batrachia. Cuvier, however, has satisfactorily shown that they are mature animals, though, as he says, they are amongst the most remarkable in the whole range of the animal kingdom. Our information as to the habits of these animals is most meagre. The best known species is the one mentioned above, and which has occasionally been exhibited alive in the Zoological Gardens in the Eegent's Park. It ap- pears to keep pretty much to the mud and muddy waters of the rice-swamps, and feeds upon worms and insects. Dr. Garden, the original discoverer of the animal, circulated wondeuful stories of its feeding habitually on serpents, as also of its extraordinary vocal powers, whence Linnasus gave it the name it bears. One step higher in the series than the Siren, and we reach the Proteus (Proteus anguimis^.fhe extraordinary inmate of the ALLIED FORMS. 171 subterranean pools in the caverns of Illyria and Carniola. In this animal two pairs of limbs are developed ; the external gills continue in addition to the true lungs, and the creature makes a still nearer approach to the ordinary reptilian form. The Proteus is in its natural state of a flesh-whiteness and transparency of colour, and decked around the neck with the brilliant scarlet fringes of its branchiae, it has a most remarkable appearance. Living perpetually in total darkness, organs of vision would be perfectly useless, and its eyes are accordingly reduced to mere points, and hidden by the skin. Closely allied to Proteus is the curious Axolotl of the Mexican lakes, an animal, it appears, regularly exposed for sale in the Mexican markets, and which, at the time of the invasion of the country by Cortez, is said to have afforded food to his army for some time. In this connec- tion, too, we must mention, though it is barely possible to do more, the Menobranchus of the great North American lakes, the Amphiuma, the Menopome, and the Sieboldia, or Gigantic Newt of Japan, of which several nearly full grown specimens have recently been added to the magnificent collection of animals in the Regent's Park Gardens. We come now to those lately adopted pets, the Water-Newts and their allies. These animals belong to the family Salamandridce, which comprehends, besides the Newts, tie true land Salaman- ders, which figure so grimly in the pages of the ancient writers on natural history. Of these redoubtable worthies we will speak in due course ; for the present, let us look at our little Newts, or Aquatic Salamanders. The Newts share not only the name of their more celebrated congeners, but their fame also ; and so widely spread and deep rooted is the belief that they are endowed with poisonous properties, that scarcely a village lad could be found who would venture boldly to grasp them in his hand. We suspect, moreover, that even amongst those who have lately adopted them as household pets, there are very few who would not, like the old lady pictiired in " Punch," prefer the tongs to their fingers if occasion should arise for handling them. It appears that we have only two distinct species of Newts in Britain ; though, from the constant variation in their appearance, the number is supposed to be at least double. Our largest species (Triton cristatus) measures, when full grown, about six inches in length, and in colour is brown above and a bright 172 SHAKSPEARE'S WALL NEWT. orange beneath. The smaller species (Lissotriton punctatus) is more faintly coloured, and hardly more than half the length of the preceding. In both species alike the males are adorned during the breeding season with a membraneous fin-like crest, which runs along the back and tail, and greatly adds to the beauty of their appearance. It appears from the interesting observations of Mr. Higginbottom, communicated to the Royal Society, that these little creatures are by no means so entirely aquatic in their habits as is commonly supposed. The larger species is undoubtedly the more strictly aquatic of the two, the smaller one, the " Wall Newt " of Shakspeare, having more of a roving disposition, and being particularly fond of the damp moss-grown walls of old buildings. Both species, however, pass a great part of their time on the land, and remain permanently in the water only during the period in which they are engaged in the great business of propagating their kind. If one may judge from the crowds which used to gather around the windows of the Aquarium dealers in which these little fellows were ex- .posed to view, they have hitherto been but slightly known to our town-dwellers, notwithstanding their abundant distribution throughout the country. In Ireland only one species appears to be generally distributed, and according to Mr. Patterson of Belfast, it is well known in that part of the country as the " man-keeper," the ignorant part of the population regarding it with great horror, from the notion that it never [fails to jump down the throat of any body that it finds asleep. The true Salamanders are strictly terrestrial in their habits, and differ from the Newts in having a rounded instead of a flattened tail. The body of the Salamander is covered with warty glands, which secrete an acrid, milky fluid, the abundance and the poisonous properties of which have given rise to some of the most marvellous stories that the mind of man ever imagined. That the fluid secreted by the Salamander is really poisonous to small animals appears certain from the experiment of Lau- renti, who provoked two lizards to bite one of these animals, in order to ascertain the effects of the supposed poisonous secretion. The Salamander at first attempted to escape, but being still persecuted by the lizards, it ejected some of the fluid into their mouths. One of the lizards died instantly ; the other fell into PLINY ON THE SALAMANDER. 173 convulsions for two minutes, and then it expired also. In another case, some of the fluid was introduced into the mouth ol a lizard by the hand of the experimenter, and in this instance the animal first became convulsed, then paralyzed on one side, and soon aftenvards it died. There appears to be no reason there- fore to doubt that the Salamander is really endowed with poisonous properties. But now, let us see how this simple fact was magnified and adorned by the ancient philosophers. No better idea can be given of the extravagant opinions of the ancients on this point than that conveyed by the following passage from Pliny. " Of all venomous beasts, there are not any so hurtfull and dangerous as are the Salamanders. As for other serpents, they can hurt but one at once, neither kill they many together ; to say nothing how, when they haue stung or bitten a man, they die for very griefe and sorrow that they haue done such a mischiefe, as if they had some pricke and remorse of conscience afterwards ; and neuer enter they againe into earth, as vnworthy to be receiued there : but the Salamander is able to destroy whole nations at one time, if they take not heed and prouide to preuent them. For if he get once to a tree, and either claspe about it, or creepe vpon it, all the fruit that it hears is infected with his venome ; and sure they are to die, whosoeuer eat of that fruit, and that by the meanes of an extreame cold qualitie that his poyson hath, which doth mortifie no lesse than if they had taken the Libard- baine call Aconitum. Moreouer, say that she doe but touch any peece of wood, billet, or hedgestake, wherwith either a loafe is baked, or a shiue of bread tested, as many as eat there- of shall catch their bane by it ; or if one of them chance to fall into a well or pit of water, looke whosoeuer dririke thereof, shall be sure to die vpon it ; and that which is more, if there happen neuer so little of the spittle or moisture which shee yeeldeth, to light vpon any part of the body, though it touched no more but the sole of the foot, it is enough to cause all the haire of the body to fall off." It appears, however, that notwithstanding these frightful at- tributes of the Salamander, " swine eat them safely ;" from which fact our author thinks " it soundeth to good reason " that the flesh of the pig should have power to "mortifie" the terrible venom. But more on that point anon. Suffice it to say here 174 THE SALAMANDER INCOMBUSTIBLE. that the same race which, furnishes the " bane " affords also the "antidote;" and though in Rome it was a common proverb, "If a Salamander bites you, put on your shroud," it was not from any deficiency of sovereign remedies. But the grand absurdity of all was the belief that the Sala- mander was incombustible ; that it not only resisted the action of fire, but could live in the midst of it without inconvenience, and extinguish it at pleasure. It is somewhat remarkable, however, that while some of the ancient writers express themselves with evident reserve and hesitation on this point, the belief appears to have held its ground long after the exaggerated idea entertained by the ancients of the animal's poisonous properties had begun to decline. Aristotle has often been quoted as giving his sanction to the belief which obtained in his time, but the language he employs " For the Salamander (as they say~), walking through the fire, extinguishes it" clearly shows that he had some doubts about the matter. Pliny expresses his doubts still more xm- cquivocally, and this is the more remarkable, since, as a general rule, the more extraordinary the stories he relates, the more ready he is to adopt them. He puts it thus : that if what the magicians report of the Salamander's power to extinguish fire had proved true, it would have been long since put in practice at Rome ; and then he adduces the authority of Sextius, who, as he says, " denieth flatly that it doth extinguish and put out the fire." It seems strange that long ages after this, Lord Bacon should be found, as in his " Sylva Sylvarum," expressing himself as in doubt whether the animal really possessed the extraordi- nary power over the flames that was ascribed to it. But that the popular belief in the incombustible nature of the Salamander still obtained appears evident from a curious reference to the subject in "The Plaine Man's Pathway to Heauen" a book, by the way, to which John Bunyan was probably indebted for the original idea of the " Pilgrim's Progress," and which, in his " Grace Abounding," he mentions as one of the two books that formed the only dowry of his wife where it is said, " As the Salamander is alwaies in the fire and neuer consumeth, so the wicked shall be alwaies in the fire of hell, and neuer consume." The last remnant of this ancient belief appears now to have passed away, its disappearance having, no doubt, been greatly expedited by what, according to the high authority of Sydney Smith, has INCONGRUOUS ASSOCIATION. 175 been mainly instrumental in freeing us from the visits of ghosts and hobgoblins, namely, the smell of the printer's ink. It is hardly necessary to say that the Salamander is not a native of Britain ; though several species are found on the Continent. The animal rarely exceeds six inches in length ; and now that it has fallen from its high estate, it receives scarcely as much notice as, from its former fame, it properly deserves. : The various members of the Batrachia which we have hitherto ntroduced to the reader in this review of their principal forms, are all distinguished by the possession of the caudal appendage throughout the entire period of their existence ; but we now advance to the highest section of the order, the members of which, with very exalted notions of their own importance, dis- encumber themselves of this badge of inferiority on their first emergence from the water, and ever afterwards walk (or rather hop) the earth, as the Anourous Amphibia or Tailless Batra- chians. In the forefront of these Batrachians par excellence stands a race of tongueless, triangular-headed Toads, represented by the monster already alluded to, the Pipa, Americana, or Surinam Toad. Captain Stedrnan, in his "Narrative of the Expedition to Surinam," describes this monster as " the most hideous of all creatures upon earth, covered over with a dark-brown scrofulous skin, very uneven, and marked with irregular black spots," and in size "often larger than a common duck when plucked and pinioned." The reader will please be so good as notice that it is Captain Stedman who is guilty of this horribly incongruous association of " the most hideous of all creatures upon earth " and roast duck. The captain had evidently a " strong stomach," or the mere making of such a comparison would have taken away his appetite for a week. And yet we are bound to state that, after all, the comparison is just; for "tastes differ," and, however incredible it may seem, your genuine Surinamese regards the Pipa as a very " duck " for the table, and, hunting it out from the dark corners of his house, makes a feast of the scrofulous monster. It is Voltaire, we believe, who somewhere Bays, that if a Toad were asked his ideal of beauty, he would most likely describe himself, and dwell complacently on a cold clammy 176 COMMON TOAD. yellow belly and a brown warty and corrugated back as the very ne plus ultra of a comely presence. In the matter of per- sonal appearance we have all of us a little weakness, and we don't know why, in the supposed case, the Toad should not have the same privilege as ourselves. But assuredly the world at large would not acquiesce in the poor wretch's complacent esti- mate of himself ; for if there be one creature which, beyond all others, is loathed and detested by mankind, it is this poor un- offending reptile. Its very name, indeed, has for ages past been a byword of reproach, associated with all that is hateful and loathsome. The poor frenzied queen in the play, in the wildest fury of her passion, can find no more biting words in which to express her utter detestation of the Duke of Glo'ster than "this poisonous hunch-backed toad ;" and Shakspeare has still more emphatically marked the Toad's pre-eminence in horror, by placing it first amongst the ingredients that are cast into the witches' caldron in " Macbeth " " Toad, that under the cold stone Days and nights has thirty-one, Swelter'd venom, sleeping got, Boil thou first i' the charmed pot." The only foundation for this old-established belief in the venomous nature of the common Toad (Bufo vulgaris), is the acrid liquid exuded from the skin, which is certainly capable of slightly affecting any very tender or wounded surface, but beyond this is quite destitute of poisonous properties. The truth is, the ungainly aspect of the Toad, more than anything else, has earned him his traditional ill repute ; and so long as the world will look upon the poor creature with such deeply pre- judiced eyes, there is no hope of his winning their good opinion. And yet the Toad has his good points, nor are they difficult to discover. That mild beautiful eye of his, for example, where will you find its equal ? It appears to us that in that placid, gentle expression of the eye, we may find the origin of the popular notion that the Toad carries a jewel in his head : " Sweet are the uses of adversity, Which, like the toad, ugly and venomous, Wears yet a precious jewel in the head." The comparison is apt and beautiful, and we are not sure that the Toad himself does not afford a good illustration of the deep SERVICES TO MANKIND. 177 moral truth it contains. Most certainly the poor creature has had no lack of " adversity," and it is no unfair inference that his mild and chastened disposition has in part at least been induced thereby. The Toad repays xis for a reputation for all that is bad, falsely and maliciously put upon him, with a willingness to be of use to us, and a readiness to receive our kindness and to recipro- cate our friendship, which fairly entitle him to a higher place in cur regard. The London market-gardeners know his value well, and we little think that some of their choicest and most dainty productions come to our tables in such good condition as they do, only because this little outcast has been keeping diligent watch and ward over the insect pests that assail them. Moreover, let those fair dames who shudder with disgust at the sight of a Toad on the garden path, remember, that but for its presence, their borders and parterres would often present an appearance not at all to their liking. It ought long ere this to have become uni- versally recognized, that the Toad is not only inoffensive and harmless, but positively and eminently useful ; that in fact it is one of the most efficient members of that great army of re- pressive agents, whose business it is, in accordance with the wise and beneficent arrangements of the great Author of nature, to check and keep under the teeming abundance of the lower forms of animal life. But the Toad is not only one of our appointed servants, he is also willing to become an intimate and confiding fr-iend. Numerous instances have been recorded of Toads that have been rendered tame and attached to those who have treated them kindly. Mr. Bell mentions that he possessed one which would sit on one of his hands, and eat the food offered to it on the other. And Dr. Lankester speaks of haviag repeatedly seen them made the domestic pets of the children of a naturalist. But perhaps the most interesting case of this kind, is that of the Toad mentioned by Pennent, in his " British Zoology ;" and though the story of this worthy has often been told, it well de- serves to be told again. The animal first made its appearance on the steps before the hall door of a gentleman's residence in Devonshire. The owner of the mansion and his family seeing the creature, frequently gave it food, and, by gentle treatment, gradually rendered it so tame, that, when they came out of an evening with a candle, it would creep out of its hole and look N 178 A DOMESTIC PET. up, as if expecting to be taken into the house and fed. It was frequently gratified in this way, being carried into the parlour, placed upon the table, and there treated to a supper, in the presence of the assembled household. The favourite food of the pet was the common flesh-maggot, a supply of which was regularly kept for it in bran. In taking its food, it would follow the maggots on the table, and, when within a proper distance, would fix its eyes and remain motionless for a while, apparently preparing for the stroke ; and then, quicker than the eye could follow, it darted out its tongue, and, catching the maggot on the point, the tongue was as rapidly withdrawn, and the maggot swallowed. This sort of exhibition excited, as a matter of course, great curiosity in the neighbourhood, and often brought the Toad a number of visitors. For the long period of thirty-six years the pet continued to occupy his hole under the door-steps of his benefactor and friend ; but one fatal day another pet, in the shape of a tame raven, espied the poor Toad at the mouth of his retreat, and, pulling him out, wounded him so badly that, no great while after, he died : and thus terminated a career, the record of which has probably done more than the most eloquent appeals to the humanity of mankind, to redeem the race from the cruel persecution to which they are exposed. The frog stands at the head of his order, the original Batrachos of the Greeks, the type and perfect model of the entire race to which in later times his name has been applied. And as the Frog stands thus at the top of the list, so his family is the most numerous of any of the sections in the order. Let us take the common Frog (Sana temporaria) as the re- presentative of his tribe ; and the first thing to be said of him is, that he is lighter and more elegant in form than his cousin the Toad, from which also he differs in having his upper jaw armed with teeth. It is to the former of these features, by which the Frog is distinguished from the Toad, that he no doubt owes in part his exemption from those ill-natured and offensive epithets which are continually launched at the head of that poor unfortu- nate. But though neither " ugly " nor " venomous," the Frog is no more of a favourite with the world at large than his puffy congener. Never, however, was a more innocent, inoffensive, and deserving creature cut off from the protection and favour that he merits. And the misfortune is, that not man alone, but numbers SNAKE AND FEOG. 179 of the lower animals as well, conspire to thin the ranks of the Frog fraternity, and to put them in constant peril of their lives. The special terror of the Frog is the common snake, which pursues its victim with relentless perseverance, and will even take the water after it, in the ardour of the chase, and secure the Frog in what may be considered its own element. The Frog appears fully conscious of its danger when pursued in this manner, and utters the most piteous screams during its efforts to escape ; and ac- cording to Mr. Bell, these cries are sometimes continued, not only after the Frog has been captured, but after it has been positively swallowed. If any of our readers desire to make proof of the Frog's terror of the snake, they have but to wriggle a walking-stick snake- fashion, after the first of these animals they find in a grass field, and before they have proceeded many yards, the wails of distress that the Frog will raise will abundantly convince them of its alarm. But experiments of this sort are not much to our liking, and we think it is only fair to the Frogs that whoever terrifies them with these imaginary dangers, should hence- forward feel bound to succour them as far as possible from all real ones. The great advocate and champion of the Frog family is tne Count de Lacepede ; and certainly they owe a debt of gratitude to this enthusiastic naturalist and true Frenchman for the eloquent defence he has made in their behalf. The only thing to which we take exception in the matter is, the Old Bailey spirit in which it is conducted the disposition, we mean, to revile one poor wretch in order to make out a better case for another in a like predicament. M. de Lace'pede is so good as to say, that the prevailing an- tipathy to the Frog is mainly the result of its resemblance to the Toad, and that if this "ignoble being," with its "revolting habits, disgusting qualities, and dangerous propensities," &c &c., had never existed, we should have thought the Frog a very paragon of excellence. Now, besides that all this is not true, it is far too obviously a mere piece of over-strained special plead- ing ; and if the Frogs can only be praised at the expense of their nearest allies, they might as well, we think, be allowed to remain out of favour altogether. It must be borne in mind, however, that M. de Lacepede was a frog-eater, and that in thus 180 A FROG-EULOGY, endeavouring to establish a broad and marked difference between the two animals, he was, perhaps, all the while, though uncon- sciously to himself, writing with an eye to the dinner-table. But let us see what M. de Lace'pede has to say. In his estimation, then, the Frog is " as agreeable in its conformation as distinguished by its qualities, and interests us by the pheno- mena which it exhibits at the different periods of its career. We behold in it a useful animal from which we have nothing to fear, whose instinct is harmless, which unites an elegant form with supple and slender limbs, and which is adorned with pleasing colours, rendered more vivid from a kind of natural varnish with which the animal is constitutionally provided. And who can regard with pain a being whose form is light, whose movements are nimble, and whose attitudes are graceful ? Let us not deprive ourselves of an additional source of pleasure, and in our walks through the smiling fields, let us not regret to see the banks of the streams adorned by the colours of these harm- less animals, and animated by their lively gambols." French- man-like, M. de Lacepede is particularly emphatic on the subject of movements and attitudes, and thus caps the climax of his frog-eulogy : " When a Frog leaves the water, so far from moving with his face turned towards the earth, and basely wal- lowing in the dirt like the Toad, he advances by lofty leaps. One would say that he desires to associate himself with the air as the purest element ; and when he rests on the ground, he always does so with his head erect, and his body raised upon his forefeet, an attitude which gives him the upright appearance of an animal whose instincts have in them something noble, rather than those which belong to the horizontal position of a vile rep- tile." It is clear, we think, as we have already suggested, that this rhapsodical praise is intended quite as much for the advan- tage of frog-eaters as of Frogs ; for is not the inference irre- sistible, that if an animal really have all these superlatively good qualities, it must be, as the Cockney phrase is, " most excellent good eating !" The Edible Frog of the Continent (Rama esculenta) is also a native of this country, although it is by no means generally dis- tributed. It is larger than the common Frog, and is readily dis- tinguished by the presence of a light line along the centre of the back. Our versatile and livelv neighbours across the Channel INCONGRUOUS ASSOCIATES. 181 do not, as is generally supposed, eat the whole of the Frog, but its hind-quarters only ; and, dressed with wine and choice sauce, they make a better dish than John Bull with his obstinate pre- ference for the " noble sirloin " would be willing to admit. It appears, however, that our neighbours themselves are losing their relish for their traditional dish ; for though the Frog is still regu- larly exposed for sale in the markets of France, its consumption has greatly diminished, and is still on the decline. One of the " things not generally known," is, that the Frog, equally with the Toad, is capable of forming an attachment to its benefactors. A case is mentioned by Mr. Bell, of a Frog which made its appearance in the kitchen of a gentleman's house at Kingston, and which for some years used regularly to come out from its hole in the skirting of the kitchen and lie down to bask in the heat of the fire. It picked up an acquaintance, too, with an old cat, and would frequently nestle under its warm fur, while the cat, on its part, would allow no interference with the comfort of its incongruous companion. Ireland, as the reader is probably aware, is singularly free from reptiles. One of our Water Newts, it is true, is generally dis- tributed throughout the island, and the small species of Toad known as the Netter Jack, is also found in some parts ; but the common Toad, the Snake, and the Viper are unknown through- out the country, as was also the case with the common Frog until towards the close of the seventeenth century, when it was introduced from England. According to popular tradition, this exemption of the " sister isle " from " varmint " is due to the malediction pronounced upon them by St. Patrick, in the days of the great King Macdonald the First, when, " The frogs went ' hop,' and the toads went ' flop,' As they dropt into the water ; And the snakes committed suicide To save themselves from slaughter." In one of the later numbers of the Tatter, an amusing account from the pen of Addison is given of the circumstances connected with the introduction of the Frog into Ireland ; and as the paper was intended as a satire upon the proceedings of the Royal Society, the incidents of the affair are made to appear sufficiently ridiculous. The plain facts of the case appear to be, that a number of Frogs were taken over to Dublin, from this country, 182 INTRODUCTION OF PROGS INTO IRELAND. and placed in the University Park, and that as the animals al perished, the ditches in the park were afterwards stocked with frog-spawn, several bottles full of which were imported for the purpose. In this way it was, that the Frog became established in the island. But at first it spread very slowly, for so late as the year 1720, the animal was nowhere to be seen in Ireland ex- cepting in the neighbourhood of the spot in which it was first planted the University Park. From about this time, however, its distribution seems to have gone on more rapidly, and to have attracted some little attention, as may be gathered from a curious allusion to the subject in an anonymous pamphlet of Dean Swift's, published about the year 1726, in which, speaking of the habit then becoming common of insuring houses against fire, he says, "The (Insurance) Society marks on our houses (under which might properly be written ' The Lord have mercy upon us') spread faster and farther than the colony of frogs ." At the present day, the Frog is firmly established in almost every part of the country, and it would task the powers of any modern St. Patrick to expel him from his haunts. The Tree-Frogs have no representatives amongst our native Batrachians, being confined exclusively to the warmer climes of the south. They are usually smaller in size, brighter in colour, and more elegant in form than their terrestrial allies ; and they live during the summer months almost exclusively on trees. They are distinguished from the ordinary Frogs by having the extremities of their toes dilated into little knobs, which usually exude a sticky secretion, of the greatest service to the animals in their arboreal evolutions. In pursuing their insect prey on the trees and bushes they move about with great activity ; some- times stealing softly towards the intended victim, in the manner of a cat towards a mouse, and then seizing it with a sudden spring. When satisfied with food, and desirous of a little rest, the Tree-Frogs frequently suspend themselves by their hind feet, or, more curious still, attach themselves by means of a glutinous secretion to the under surface of a leaf, and so rest concealed beneath its shade. Both Frogs and Toads are regular croakers, as everybody knows, but everybody is not aware how various and diversified in the different species is this vocal performance. The croak of the common Frog is a rather dull and uninteresting affair, but his VOCAL PERFORMANCES, 183 cousin, the edible Frog, has a much more sonorous voice, and in our fen counties where they occur, have earned the names oi "Whaddon Organs and Cambridgeshire Nightingales. In France, where, of course, cliis Frog is abundant, it was a common custom up to the time of the first revolution, for the menials belonging to the great castles of the nobility, to lash the water in the ditches and moats every morning, in order to quiet the Frogs and keep them from disturbing my lord and lady. The Tree-Frogs litter a shrill treble note ; and it is probably to one of this kind that Mr. Wallace refers in his " Travels on the Amazon,'' which had, he says, such an agreeable whistle, that could it have been brought into civilized society, it would probably have had as many admirers as the singing mouse, or the still more marvellous whistling oyster described by " Punch." Mr. Darwin mentions one of these American Tree-Frogs, which, he says, sits on a blade of grass about an inch above the surface of the water, and sends forth a pleasing chirp, several of them sometimes getting together and singing in harmony in different notes. At the vocal antipodes of the Tree-Frog, is the Bull-Frog, whose deep hollow voice resembles the bellowing of a bull. In Germany there is the Laughing-Toad, a dapper sort of creature that can leap like a Frog, and utters a noise like that of a man laughing But for this variety of the croak, the most famous of the race is' the Jocular Toad of the desert shores of the Caspian and the Volga, which appears, of an evening, to become so exceedingly hilarious, that the traveller in those solitary regions is apt to fancy he has come unawares upon a company of men and women laughing heartily together, and is not a little surprised to find that the boisterous merriment proceeds from a number of huge Toads celebrating their nuptial rites. We have no space now to discuss at proper length the great " toad-in-a-hole " question, which has recently been revived by Mr. Gosse, and which has long attracted the attention of the curious. Is it true that Toads and Frogs have been found alive enclosed within masses of stone and clay, or similar substances, where they have been wholly cut off from air and food, and im- mured for perhaps thousands of years ? That is the question ; and, in spite of all alleged discoveries to the contrary, we must persist in believing that the question answers itself. The thing is impossible. No doubt many remarkable cases have occurred 184 GREAT TOAD-IN-HOLE QUESTION. in which these animals have been discovered in situations whera they have been in great part enclosed in solid substances, and more or less deprived of food and air for cor. -iderable periods ; but that any animal can live for a lengthened time wholly and entirely deprived of food and air, is so diametrically opposed to all that we certainly know on the subject, that the supposition is too extravagant to be entertained for a moment. The truth is, the discoveries, curious and remarkable enough, no doubt, on which the popular belief on this subject is founded, have gene- rally been made by persons quite incompetent to decide on a matter requiring such careful and accurate observation. Mr. Jesse, in his " Gleanings in Xatural History," argues strongly in favour of the popular notion, and mentions several instances in which not only Frogs and Toads, but Snakes and Eels are said to have been discovered alive enclosed in solid blocks of stone. But, as is almost invariably the case, nothing but " hearsay " evidence is given, and that, too, of the loosest and most unreliable character. In so far as actual experiments have thrown any light upon the subject, those instituted by Dr. Buckland establish conclusively that the Toad, when deprived of food and of all access to the external air, is incapable of subsist- ing, at the longest, for more than about twelve months. What seems thus to be proved with respect to the Toad is no doubt equally true of the Frog ; and we may rest assured all supposed discoveries to the contrary, notwithstanding that no ante-dilu- vian Frog or Toad has ever yet been seen, in our day, alive. There are real wonders enough in nature without our making fictitious ones of our own, and with this latter class must cer- tainly be ranked the popular notion on this subject. It has already been hinted, that, as the ancients regarded some of the Batrachia as highly venomous, so also they found amongst them some whose curative powers were no less remarkable. It was to the various kinds of Frogs especially that these extraordi- nary curative powers belonged ; and if we may take the statements of Pliny as our guide, it would appear that these animals were able, in one form or another, like some of our modern panaceas, to remove nearly " all the ills that flesh is heir to." We cannot, of course, go into this matter at any length, and shall, therefore, notice only some of the more curious forms in which the Frog remedy was administered. ANCIENT FROG REMEDIES. 186 In the first place, then, there is, in addition to remedies of other kinds, a couple of sovereign Frog remedies against the poison of the Salamander '' the flesh of sea-tortoises, mixed and incorporat with the flesh of frogs," and " the decoction of sea- frogs sodden in wine and vinegrc," which last, it appears, is " soueraine " also for the venom of the " hedge-toad." The " broth " of fresh-water frogs is very good against the prick of scorpions, the poison of the " sea-hare," and the sting of serpents. If any reader should after this suffer from toothache, the following remedies are highly recommended : If the pain proceed from loose teeth, cut off the feet of two frogs, lay the bodies to steep in wine, and then wash the teeth with the infusion ; or which is doubtless still better, apply the frogs " whole as they be, legs and all, outwardly, to the chawes, and keep them fast thereto." If the entire side of the face be affected, " take the hearts of thirty- six frogs, and bake or boile them in one sextar of old oile, vnder a pan or ouen of brasse," and then pour the " grauie or liquour " into the ear of the side affected. If the " grinders and great jaw teeth do ake," a " spcciall medicine " for them may be had by seething frogs in vinegar and then holding the liquor in the mouth. " But," says our author, " because many a man's stomack lothed and abhorred such a medicine, Sallustius Dionysius found the means to hang many of them by the hinder logs ouer a vessell or pan of seething vinegre, that out of their mouth there might fall the humour within their bodies into the said vinegre. But to those who had good stomackes, and were of stronger complexions, he prescribed to eat the very frogs broth and al wherein they were sodden." Oil in which frogs have been boiled is a certain cure for the gout. "The fat of frogs dropt into the cares allaicth their paine presently." But in truth, every /art of the frog would appear to be wonderfully medicinal, and that, too, not only when taken internally, but even when worn about the person. The eye of the frog wrapped in russet cloth and hung round the neck, cures an inflamed or bleared eye ; the heart of a frog hung round the neck, or tied to the arm, diminishes and shortens the cold fit of an ague ; while either frog or toad (" the nails whereof have been clijij-r-d "), hung anywhere about the body of " one that is sicke of a quartan ague, riddeth away the disease for euer." But perhaps the most wonderful cure after all, is that of an ordinary cough, in order to be rid of 186 AN UNEXPECTED APPEARANCE. which one has but to catch a certain " little frog that vseth to climb trees, and from thence crieth and croaketh," and having caught it, to spit into its mouth and let it go again ! Our readers will perceive that whatever may be thought of frogs and frog remedies in these days of hydropathy and homoeopathy and universal panaceas, they held a high and distinguished position in the ancient pharmacopoeia. No one who has visited the geological restorations in the grounds of the Crystal Palace at Sydenham can fail to recall the ungainly figure of the huge frog-like beast that is represented grimly eyeing the spectators across the water, from the extremity of the first of the three islands in the lake. In this monster, Mr. Waterhouse Hawkins has given us the probable figure and dimensions of the great original and herald of the Batrachian order. For a considerable while, indeed, the Labyrinthodou, as the monster has been christened, was regarded not only as the first introduced of Batrachians, but as the earliest or most ancient form of all air-breathing vertebrated animals. The first-dis- covered traces of the monster occurred in the form of footprints in rocks belonging to the new red sandstone formation, and their discovery astonished the geologists of the day almost as much as the human footprint in the sand astonished our old friepd Eobinson Crusoe. It was a circumstance for which no one was prepared. The universal belief amongst geologists, up to the discovery of these footprints was, that prior to, and during that period of the earth's history represented by the new red sand- stone rocks, no animals higher in the scale of being than fishes had been called into existence ; in other words, that up to that time, the entire life of the globe was confined to the waters of the ancient ocean, and that such portions of the solid crust of the earth as were raised above the waters, and constituted dry land, were altogether desolate and void of life. Here, however, in the newly discovered footprints, was unquestionable evidence that, all unsuspected by the geologists, a large land animal had walked the earth in those early times ; although, so far as was then known, no other memorials remained of it than the impressions of its feet, left in what was once the outspread sands of the ancient sea-shore. Nothing more of course was at first known of the monster than could be gathered from the prints of its large hand-like feet ; but after a while, teeth, bones of the extremities, AiV ARGUMENT UPSET. 187 portions of the skull, and other remains were brought to light, and being submitted to a careful scrutiny by Professor Owen, ho demonstrated that they belonged to one and the same creature? an enormous extinct Frog. & The strictly Batrachian character of the Labyrinthodon is evi- denced by many structural peculiarities of great importance ; and the fact that an enormous Frog was thus, as it was then supposed, the first of land animals that had appeared on the surface of our planet, gave a weight of evidence to the once-famous " hypothesis of development" of which its advocates were not slow to avail themselves. But unfortunately for this ill-starred speculation, the argument it drew from the structure and time of appearance of the Laby- rinthodon has since experienced a double break-down. In the first place, other and higher forms of reptilian life have subse- quently been discovered in formations older by far than the new red sandstone rocks ; and secondly, the Labyrinthodon itself has now been shown to have been, not a Frog pur et simple, as was first supposed, but a Frog of mixed character, so to speak a creature combining with its Frog-like characters, others which give it a close and intimate relationship with the highest order of reptiles. It is obvious, therefore, that the man-monkey theory is not only not supported, but sadly discountenanced by this most ancient of the Ancient Order of Batrachians. 189 CHAPTEE IX. OUR FEATHERED FRIENDS. " Birds, the free tenants of the land, air, and ocean, Their forms all symmetry, their motions grace." THE Tory Fox Hunter, of whom Addison has given such a racy sketch in the " Freeholder," is a right sensible old gentle- man in some respects after all ; and nowhere does he show to greater advantage than there in the park, " at the side of Rosa- mond's Pond, pulling a handful of oats out of his pocket, and with a great deal of pleasure gathering the ducks about him." It gives one an immense advantage over the crowd of mere lookers-on at such a place to be able to deal out the contents of a well- stored pocket, and with a little skill in the distribution of your favours, you may easily get up a very pretty aquatic entertain- ment in which feathered performers from all the " five " quarters of the globe do their best to amuse the company. The water-fowl in St. James's Park are old friends of ours, and have often beguiled us into idling away an hour under the fine old elm-trees which adorn the banks of the lake. The place itself is a very agreeable one, and seated there beside the water on a summer afternoon, with the Club Houses, the Royal Palaces, and the venerable old Abbey, all in view between the trees, the roar of the great city mingles pleasantly with the rustling of the leaves overhead, and gives one a comfortable sense of security against all interruption from the noisy world outside the park It sometimes happens, indeed, that what with the comparative quiet and seclusion of the place, the heat, and the glare from the water together, we drop off into a sort of waking dream, and, all unconscious of the human accompaniments round about us, fancy ourselves far away on some distant shore or river bank, attending to one or another of our vivacious friends upon the water in their own proper homes. There is one thing, however, 190 ASSISTANCE WANTED. of which we sadly feel the want in these open-eyed excursions into dreamland, namely, some convenient ornithological " Who's Who ?" to supply us with the names and the original geogra- phical whereabouts of the different memhers of the feathered fraternity. With most of the party we can get along pretty well by ourselves, but the appearance of a single strange fowl is enough at times to put a stop to our musings, and to make us feel how acceptable would be a plain, practical "handy-book" of aquatic ornithology. " If this should meet the eye " of the Et. Hon. gentleman who is charged with the care of Her Majesty's woods and forests, we would humbly submit to him that this is a matter in respect to which he might very appropriately afford us a little of bis official assistance. That assistance is given in one direction, aud it ought to be given in the other. The case is this : In the park gardens every tree or shrub of any interest is carefully indicated by an iron label,, duly setting forth its scientific and its English name, the family of plants to which it belongs, its native country, and the date of its introduction into Britain ; and yet, from one end of the park to the other, there is not so much as a painted board to guide us to a knowledge of the splendid collection of aquatic birds which disport themselves on the ornamental water. But why should not the birds have their labels as well as the bushes ? If there be any conceivable reason for providing a label specially to tell the world that yonder scrubby-looking bush is " Buxus sempervirens, The Common Evergreen Box, An Euphorbiaceous Shrub, Native of England," surely there is just as good a reason for telling us in the same fashion that the Duck making off from under the said Buxus is no other than Anas mollissima, the Eider Duck which weary heads will never fail to bless, or that those Geese sailing along under the bank there are the famous Bernicle Geese (Anser leucopsis) which, in days gone by, used to grow upon trees, like apples, and when they were ripe for the change, dropped into the water and swam away, true feathered fowl ! We do not forget, of course, that our feathered friends are endowed with rather active powers of locomotion, and that unless they were made to wear the labels round their necks which it is highly probable that neither the birds themselves, nor their owners, the Ornithological Society, would very well like a set of A HETERODOX SUGGESTION. 191 labels would be of little service in enabling uninitiated people to indentify the different species. That is very true ; but a little help is better than no help at all ; and we are by no means sure but that, properly arranged along by the side of the water, in some suitable and conspicuous position, a series of labels would teach a great deal more than might at first be supposed. It will certainly do no harm to try the experiment ; so, pray Mr. Woods- and-forests, be so good as give us the names of our friends, aud tell us, too, whence they originally came. It would open the eyes of a good many of the habitues of the park to see it duly set forth that there are no less than four or five distinct species of those noble birds, the Swans, to be seen upon the ornamental water ; but with eyes open to the fact the points of difference between the different species would soon be recog- nized. The tame Swan (Cygnus olor), distinguished from its congeners by the caruncle or berry on the bill, as also by the graceful carriage of its neck, which, when the spirit of the bird ia up, gives it such an air of grandeur on the water : " The Swan with arched neck, Between her white wings mantling, proudly rows Her state with oaiy feet." It is commonly said that this graceful peculiarity in the bear irg of the Swan is owing to the fact that it has an unusual number of vertebrae in the neck ; but that explanation, although a true one so far as it goes, is not of itself sufficient. All the Swans are similarly endowed in that respect, and yet none but Cyynus olor knows how to throw its neck into the elegant curve in question. How shall we account for the difference ? It is very heterodox zoologically no doubt, but we are ourselves inclined to think that it is simply the result of good breeding, one of those courtly airs which the bird has caught from its long association with royal and other courtly beauties. But that it early caught the trick we have the most positive evidence ; for in an ancient cameo representing Leda and the Swan, the bird has the same elegant bending carriage as is now observable. The ornithologists have revenged themselves upon the ancient and mediaeval writers or their fables respecting the vocal powers of the Swan, by dubbing it the mute Swan. In this, however, they have simply gone from one extreme to another. It was no doubt 192 THE MUSICAL SWAN. very absurd in Albertus Magnus to speak of the Swan as the " largest of singing birds," but it is not much wiser to call it a mute. That it is not absolutely voiceless may be ascertained without trouble ; and it is well known to those acquainted with the habits of the bird, that in spring and summer, when leading about its young brood upon the water, it breathes a soft plaintive cry, which, coming from an aquatic bird, is no bad apology for a song. It is not at all improbable that the exaggerated notion which formerly obtained on this subject may have originated in part from confounding Cygnus olor with the Hooper or Whistling Swan (Cygnus ferus), and thus attributing to the former the qualities of both. Not that the Hooper can make any great pretensions to song either, though he does constantly make himself heard, " clangingly on sounding pinions," as Homer ex- presses it ; and what is still more to the purpose, is found to this day about " Cayster's flowery side." That the loud trumpeting call of the Hooper is not an unmusical sound is vouched for by Bechstein no mean authority on singing birds who proposed to give it the specific name of musicus. But as priority is everything in the nomenclature of science, Limueus's appellation of ferus is still retained in preference. The main point, however, in the ancient story, is not that the Swan was vocal, but that its vocal powers were greatest, and that it sang most melodiously, just before its death. " It never smokes but there is fire," says the proverb, and though there is no doubt a great deal of poetic dressing in this " Swan song " story, we are yet strongly inclined to suspect that there is truth at the bottom if we could only get at it. Let us try. Bechstein's Musical Swan will still help us. The Hooper is an occasional winter visitor to the British Islands, and Mr. St. John, in his " Wild Sports and Natural History of the Highlands," gives a very interesting account of its habits. Amongst other things he treats us to a spirited descrip- tion of a Swan-shooting adventure, of which the following is the conclusion : " I was not above forty yards from them, so gently raising my- self on my elbow, I pulled the trigger, aiming at a forest of necks. To my dismay the gun did not go off, the wet or something else having spoilt the cap. The birds a herd of between fifty and ORIGIN OF THE STORY. 193 sixty Hoopers were slow in rising ; so without pulling the other trigger, I put on another cap, and standing up, fired right and left at two of the largest Swans as they rose from the loch. The cartridge told well on one, who fell dead into the water : the other flew off after the rest of the flock, but presently turned back, and after making two or three graceful sweeps over the body of his companion, fell headlong, perfectly dead, almost upon her body. The rest of the birds, after flying for a short distance away, also returned, and flew for a minute or two in a confused flock over the two dead Swans, uttering their bugle-like and harmonious cries ; but finding that they were not joined by their companions, presently fell into their usual single rank, and went undulating off towards the sea, where I heard them for a long time trumpeting and calling." Now it strikes us that in the incidents of this adventure we have all the materials that are necessary to account for the ancient story, and we have little doubt that it really did originate in some such fashion. Eley's cartridge, swan-shot, and double barrels are all modern inventions of course, but there were well- feathered arrows and trusty bows even in Homeric times; and sacred though the Swan was to Apollo, it no doubt often fell a victim to " crack shots " thus primitively equipped. If this be granted, and that the habits of the bird were the same then as now, there is nothing more required. For what would be more natural than that the affectionate solicitude of the birds for their slaughtered companions, prompting them, regardless of their own salety, to linger lovingly about the dead bodies, " uttering their bugle-like and harmonious cries " the while, should strike the attention, and be celebrated in song, and that the story once set going should grow and grow, as stories always do, until at length it assumed the shape in which we know it? It is thus that stories of the kind commonly arise, and we see no reason to doubt that such was the origin and history of the famous story of the dying Swan's song. The Black Swan (Oygnus atratus) is an Australian bird, and was first made known by the early navigators who visited that insular continent in the south. Although it was first introduced into England not more than sixty years ago, it has now become BO thoroughly acclimatized and hardy, that it breeds with us even more freely than the common Swan. lu 1858 a pair of these birds o 194 EKGLISH BIRDS IS AUSTRALIA. in the jx>ssession of Samuel Gurney, Esq., of Carshalton, hatched no less than three broods of cygnets, numbering in all twenty-one young ones, in about ten months. The third brood was produced towards the middle of November, when the weather was in- tensely cold ; and one morning, when the young birds were between three and four days old, they were found actually frozen into the ice, although they did not in any way suffer from it. Our Australian colonies have long since sent us their Black Swans and Emeus, and their brilliant Parrots and Cockatoos, and they are now getting back some of our own feathered friends in return. For some time past, great efforts have been made to introduce into Australia not only our ordinary game birds, but many of the little songsters that enliven our woods and fields. A certain yearning after the old home pleasures lies deep in the heart of the emigrant, and it is no doubt with a view to the gratification of this longing that so much spirit and determination is shown in the endeavours to stock the Australian colonies with the common singing birds of this country. Many hundreds of English singing birds, including Larks, Gold6nches, Linnets, Thrushes, and Blackbirds, have been imported for the purpose ; and there is good reason to believe that the Lark, if not one or two other birds as well, is now firmly established in the country. The matter is still being prosecuted with great spirit by the colonists, and large sums of money are subscribed for the purpose. It is by no means improbable, therefore, that before long the Australian " bush " may be vocal with the songs of many of the little choristers which lend such a charm to our own fields and hedgerows. The introduction of some of our game birds has already to a certain extent been accomplished. The Pheasant is now bred with ease in several parts of the country ; the Partridge is being attended to with good prospect of speedy success ; and in Tas- mania the Peacock itself already breeds wild in the woods. Before long, therefore, we may expect to hear that the favourite field sports of Old England are being pursued at the antipodes as part and parcel of the ordinary life of the Anglo-Australian people. The race of web-footed birds is somewhat remarkable, as com- prising within itself the two extremes of the feathered tribes iu respect to their qualifications for flight. In some of these birds, THE GREAT AUK. 195 as the Albatross (Diomedea exulans) and the Frigate-bird (Fre- gata aquilus), the wings receive their highest degree of develop- ment, and become such effective organs of aerial locomotion as to enable these birds to live almost continuously in the air, fre- quently at the distance of a thousand miles or more from the land. In others, as the Penguins, the wings are reduced to mere flippers, which, powerless for the purpose of flight, serve the birds in the water as fins for swimming, and on the land as a fore pair of limbs, by means of which they hobble along on all fours, after the fashion of an ordinary quadruped. The bird which is best known for this quadrupedal procedure is the famous Jackass Penguin (Aptenodytes demersa"), and it has this additional claim to its elegant appellation, that it makes a loud and most discordant noise, very like the braying of its namesake. The Penguins belong exclusively to the south, and are repre- sented in the northern hemisphere by the Auks, to one of which the attention of naturalists is now directed in a very especial manner. It appears that the Great Auk (Alca impennis) , a noble bird nearly three feet in length, and once an occasional visitant to the British Isles, is on the point of becoming extinct, if, indeed, it be not already a thing of the past. The fact of a large bird thus dying out apparently in our own day, has naturally excited great interest, and has led to a careful investigation of all the circum- stances of the case. In early times the principal haunts of the Great Auk appear to have been the eastern coast of Newfoundland and Labrador, where they existed in immense profusion. On the Newfoundland fishing-banks the Great Auk was two centuries ago to be found in great abundance. Its appearance was always hailed by the mariner approaching that desolate coast as the first indication of his having reached soundings on the fishing-banks. During the sixteenth and seventeenth centuries, these waters, as well as the Iceland and Faroe coasts, were annually visited by hundreds of ships from England, France, Spain, Holland, and Portugal ; and these ships actually were accustomed to provision themselves with the bodies and eggs of these birds, which they found breed- ing in myriads on the low islands oft' the coast of Newfoundland. Besides the fresh birds consumed by the ships' crews, many tons were salted down for future use. In the space of an hour, these old voyagers tell us, they could fill thirty boats with the birds. 196 EXTINCTION OF THE SPECIE8. It was only necessary to go on shore, armed with sticks, to kill as many as they chose. The birds were so stupid that they allowed themselves to be taken up on their own proper element by boats under sail ; and it is even said that on putting out a plank it was possible to drive the Great Auks up out of the sea into the boats. On land the sailors formed low enclosures of stones into which they drove the birds, and as they were unable to fly, kept them there enclosed till they were wanted for the table. It is said, too, that as the birds were fat and burnt well, they were actually used for fuel, as the dried bodies of the Auks and Guillemots are still employed on the Westermann Islands.* As may be supposed, this wholesale slaughter of the birds speedily reduced their numbers, and there is no certain informa- tion that any individuals of the species have been seen on those coasts during the present century. The last known breeding- places of the bird are two isolated rocks, extremely difficult of access, off the south coast of Iceland ; and at long intervals, sometimes of ten or fifteen years, a few individuals have been obtained thence up to the year 1844:. In that year a pair of the birds, male and female, were shot at their nest on a little islet near to one of the former breeding-places, and since that time, notwithstanding that the most careful search has everywhere been made for it, the Great Auk has nowhere been seen alive. It is conjectured that the bird may still be an inhabitant of the inaccessible shores of East Greenland, though none of the vessels passing that way ever come across it, nor has it ever been seen by any of the Arctic exploring expeditions. It may of course yet be discovered on some part of that ice-bound coast ; but it is by no means improbable that the Great Auk has now ceased to exist, and has thus taken the place till now occupied by the Dodo, of the last in the series of extinct birds. The most generally diffused, perhaps, of all our birds of pas- sage are the different members of the Swallow tribe, which every- where in northern lands are welcomed as glad harbingers of approaching summer. Of the four species of these birds which regularly migrate to the British isles, two species, the Swift, the largest, and the Sand-Martin, the smallest of the four, are com- * On the Great Auk.

A RAILWAY COLONY. 197 paratively but little known ; while the other two, the Chimnej'- Swallow and the House-Martin, are very generally confounded with each other. It will not be out of place therefore to say a few words here by way of pointing out to the non-ornithological reader the distinctive marks of these most familiar of our fea- thered friends which come to us from afar with every returning summer. Our first visitor is the Swallow (Hirundo rustica), which gene- rally makes its appearance just before the middle of April, pre- ceding the other members of the tribe by a few days. As its name implies, it is somewhat of a rustic in its habits, and seldom ventures to take up its residence in the immediate vicinity of large towns. The Martin (Plirundo urbica), on the other hand, is quite a town dweller, constantly haunting the busiest tho- roughfares of our largest cities, and is almost as familiar in Cheap- side and Fleet Street as the Sparrows themselves. It is not in- sensible, however, to the quiet and the purer atmosphere of the country, and is even there much more commonly seen than the Swallow, for which it is mistaken. There is no difficulty in dis- tinguishing the two birds even on the wing, the Martin being at once recognizable by the snowy white of its throat and breast, and by the conspicuous patch, of the same colour on the back at the base of the tail. The distinctive marks of the Swallow are its forked tail and the patches of rusty red on its forehead, chin, and throat. Another point of distinction between the two birds is the place selected for nesting ; the Swallow invariably building in chimneys or against the rafters of bams and out-houses, while the Martin constructs its nest under the caves of houses, the sills of windows, and other similar situations. The boldness and pre- suming confidence of the Martin in selecting exposed and easily accessible situations for its nest has often been noticed ; but we never met with a more remarkable instance of this sort of daring than is displayed by a colony of these birds which, year after year, attach their nests to the pillars that support the roof of the railway station at Worthing. It is a long row of slender iron pillars, about eight or ten feet high, and scarcely more than a yard distant from the rails on which trains are continually passing, and yet almost every pillar in the row has a nest on each side of it, the nests being supported in some cases by pro- 198 HYBERNAT10N OF SWALLOWS. jecting pieces of wood which the railway men have fastened up to secure the establishments of their little confiding friends. Notwithstanding the bustle and noise that precedes and follows the stopping of a train, the birds fly backwards and forwards to their young broods without the least hesitation ; stopping only while the trains are at rest at the station, during which time the bright-eyed, white-throated little fellows look out of their door- ways and very composedly survey what is going forward. In the four charming letters devoted to the Swallow tribe in White's " Selborne," the manners of these engaging birds are described with a fulness and minute particularity of detail which has left little or nothing for subsequent observers to record, as it gives them little or nothing to correct. On one point, it is true, the historian of Selborne gives his coimteuance to a fallacy re- specting these birds which finds but few supporters at the pre- sent day : we allude, of course, to the opinion once commonly entertained that, at the approach of winter, the Swallows retire, not to the warmer regions of the south, as is now known to be the case, but to the bottom of ponds and streams, there to remain, buried in the mud, in a state of torpidity until the return of spring. The aecounts which have from time to time been given of the discovery of Swallows in a state of torpidity, in caves and hollow trees, and such like places, are for the most part of the same apocryphal character as the stories already noticed of showers oj Frogs, and Toads embedded in the solid rocks, and are entitled to about the same amount of credit. Some of the most striking cases on record are those mentioned by Bishop Stanley in his " History of Birds ;" but they are in no respect more explicit and reliable than Old Gerard's or Sir Robert Murray's personal testimony to the Goose-bearing qualities of the Barnacle-tree, or to the authorities that could be cited for a dozen other popular delusions of the same character, which are now altogether exploded. One of the most amusing of these stories of hybernating Swal- lows is that told by Derham in his Physico-Theology, in which " an ancient fisherman, accounted an honest man," is represented as having discovered at a very low ebb of the tide on the coast of Cornwall, a great number of Swallows and Swifts hanging by their feet to one another, and adhering to the rocks, " where THE CUCKOO. 199 they were covered commonly by the sea-waters, but revived in his warm hand and by the fire." It is a great pity that thesa " ancient fishermen " and other fortunate individuals of the sort never come in the way of anybody competent to pronounce on the value of their wonderful discoveries. It is not improbable that these stories of hybernating Swallows may have originated in the occasional discovery of individuals which, having been left behind when the autumnal migration has taken place, have retired at the approach of winter to some se- cluded retreat, and there perished with the cold. But there is no reliable evidence that in any single instance have Swallows been discovered in such circumstances alive. The Swallows and their nocturnal ally, the Goat-sucker, or Nightjar (Caprimulgus Europceus), form the lowest section of the great order of Perching Birds, which includes by far the largest proportion of our more familiar feathered friends, some of which Shakspeare, anticipating of course our modern classification, has thus lightly strung together : " The ousel-cock, so black of hue, With orange-tawny bill ; The throstle with his note so true, The wren with little quill ; The finch, the sparrow, and the lark, The plain-song cuckoo gray." The extraordinary habit of the Cuckoo (Cuculus canorus) in depositing its eggs in the nests of other birds, and leaving to them the entire care of its offspring, has naturally excited great attention ; and though it would be too much to say that the reason of this strange procedure has been satisfactorily ascertained, yet the examination of the structure of the bird to which it has led, has certainly thrown a good deal of light upon the subject. It appears that owing to the peculiar conformation of the Cuckoo, its eggs are not only small for a bird of its size, but that they are developed singly, and at intervals of six or eight days each ; so that if the bird were itself to hatch the eggs it lays, it would be involved in the predicament, supposing such a thing possible, of having the threefold business of oviposition, incuba- tion, and feeding one or more already hatched young, all on its hands at once. The situation of a poor bird so circumstanced would certainly not be an agreeable one, and that no such 200 HABITS OF THE CUCKOO. catastrophe may occur, the Cuckoo, wisely taught, relieves her- self of all the trouble and anxiety of nest-building and nursing, and depositing her eggs, each as it is ready, in the nest of some small bird, and never more than one in the nest of the same bird, has her family brought up for her after a fashion not more con- ducive to her own ease and comfort than to the comfort aud safety of her offspring. And the same wise instinct which thus leads the Cuckoo to distribute her family in the nests of other birds, leads her un- erringly to select as their foster parents such birds only as subsist on the insect food adapted for her young. The Hedge-sparrow is the one usually selected, but the Eeed-sparrow, the Titlark, the Water-wagtail, the Yellowhammer, and the Linnet, are all of them occasionally pressed into the service, and a case is men- tioned in which the burden was laid upon a poor diminutive Wren. Thus much as to the parent Cuckoo ; but the procedure of the young bird is no less remarkable. It is no sooner hatched than it begins to shoulder out of the nest all the eggs or young birds which may happen to be there, and it is qualified for the ungrateful business in a very peculiar manner. Its back, it appears, is very differently shaped from that of other newly hatched birds, being unusually broad from the shoulders down- wards, with a considerable depression in the middle, which seems specially designed for giving a secure lodgment to an egg or a young bird. No wonder that, being thus specially adapted for the work, the young Cuckoo easily contrives to get the eggs or young birds in the nest on its back, and then raising itself with a sort of jerk, tosses them over. It is a very noteworthy circum- stance, moreover, that the depression in the back, intended as it would seem for the express purpose of aiding the young bird in getting rid of its companions, fills up and disappears in about ten or twelve days, by which time of course the Cuckoo has got the nest to itself. Pliny has an entire chapter devoted to the Cuckoo, and as a matter of course he has a good many curious things to say about it, which read none the worse for the quaint dressing of our friend Philemon. The best part of the story is that which relates to the young bird and its hapless foster parent, which it appears pays a terrible penalty for its attention to the young ingrate. But here is the story : " And this young Cuckow being greedy AN OVER-FOND MOTHER. 201 by kind, beguiling the other young birds, and intercepting the meat from them, groweth thereby fat and faire-liking ; whereby it conies into speciall grace and favour with the dam of the rest, and nource to it. She joieth to see so goodly a bird toward ; and wonders at her selfe that she hath hatched and raised so trim a chick. The rest which are her owne indeed, she sets no store by, as if they were changelings ; but in regard of that one, counteth them all bastards and misbegotten ; yea, and suffereth them to be eaten and deuoured of the other euen before her face : and this she doth so long, untill the young Cuckow, being once fledge and readie to flie abroad, is so bold as to seize on the old Titling, and to eat her up that hatched her. And by that time there is not another bird again for goodnesse and sweetnesse of meat comparable to the young Cuckow." The food of the Cuckoo consists almost exclusively of insects o various kinds, but principally caterpillars, though it appears occasionally to vary its diet by partaking of berries and garden- fruits. It is commonly believed by country people that the Cuckoo occasionally indulges also in the eggs of small birds. Hence the allusion in the well-known rhyme : " The Cuckoo's a fine bird, She sings as she flies ; She brings us good tidings, She tells us no lies. She sucks little birds' eggs To make her voice clear ; And when she sings ' Cuckoo ' The summer is near." There is some reason to believe that this charge is really true. Mr. Jesse mentions the case of one which was kept in a cage, and fed regularly on fresh meat cut small and mixed with soaked bread and raw egg, and which at length killed itself by attempting to swallow a Yellowhammer's egg, at which it eagerly caught. Moreover Audubon says distinctly that the yellow-billed Cuckoo of America (Cuculns Americanus), which, by the way, is an occasional visitor to our own shores, constantly robs the nests of smaller birds of their eggs, which it sucks with great avidity. One of the most brilliant of British birds is the Kingfisher (Alcedo ispida), the Haley on of the ancients, which according to Aldrovandi is " the most celebrated and besung " of all feathered fowl, real or imaginary. 202 THE KINGFISHER. No words can do justice to the Kingfisher ; and if you would know what he really is, you must make your way cautiously to some quiet stream overhung with bushes, where, on a projecting bough, you may chance to see him as he sits motionless, shining in the sun like a sapphire gem watching for his prey. Be still, and in half a minute you will have proof of his skill as a fisherman. See ! he darts from his station a line of bright green light, at the end of it a splash in the water, and he is gone. But only for a moment, for now he emerges from the stream, and in his bill is a little fish, whose scales glisten in the sun for an instant, when it is beaten to death against a stone and swallowed whole. In far less time than it has taken to describe, the fish is caught and swallowed, and the bird is back to its station again, where it sits and waits as before, till another plunge marks the capture of another fish, for the Kingfisher rarely misses its prey, and so on, till perhaps half a dozen are captured in little more than as many minutes. It is somewhat strange, considering the high-flown descrip- tion which the ancients have given of the Kingfisher's nest, that it is still an undetermined question with naturalists whether the bird really builds any nest at all. Its general habits are very well known, but there is still a doubt as to its procedure in this one particular. The question at issue, however, is a very narrow one. It is well known that the birds rear their young in the banks of the streams they haunt, either digging a hole them- selves, or taking possession of that of a water-rat, which they afterwards enlarge to suit their convenience. The direction of the hole is always diagonally upwards, and it generally pene- trates from two to three feet into the bank, the end being scooped into a sort of hollow, at the bottom of which there is always a quantity of small fish-bones mixed with earth, on which the bird lays its beautiful transparent pinkish-white eggs. The point in dispute is, whether these bones are to be con- sidered in the light of a ~bona fide "nest," or merely as a casual accumulation cast up by the parent birds irrespective of any view to nidification. Mr. Gould, who in his " Birds of Europe " advocates the latter view, has recently communicated to the Zoological Society the particulars of a discovery he has made, which leads him to udopt the opposite opinion, namely, that the parent birds pur- A DISPUTED POINT. 203 posely deposit the fish-bones " as a nest," to defend their eggs from the damp earth. The discovery which has led to this change, was that of a nesting-place of the Kingfisher in the banks of the Thames, from which a nest and eggs were twice dug out A fortnight after the first nest was taken, the female bird was seen to leave the hole again, as though she had returned to her old breeding quarters : a week later the hole was examined, and the old bird was ascertained to be inside. " I then took," says Mr. Gould, " a large mass of wool from my collecting-box, aiid stuffed it to the extremity of the hole, in order to prevent the eggs and nest from damage during my again laying it open from above. On removing the sod, and digging down as before, I came upon the cotton wool, and beneath it a well-formed nest of fish-bones, the size of a small saucer, the walls of which were fully half an inch thick, together with eight beautiful eggs and the old female herself. This nest and eggs I removed with the greatest care : and I now have the pleasure of exhibiting it to the Society, before its transmission to the British Museum, the proper resting-place of so interesting a bird's nest." By the kind permission of Mr. Gray of the British Museum, we have been allowed to inspect this interesting specimen, and we must say, that if it really be a nest in the proper sense of the word, the difference between a bird's nest and a mere mass of fish-bones and loose earth is much less than we had anticipated to find it. But Mr. Gould is not merely an authority ; he is-the ttighest authority on all matters ornithological, and if he is satis- fied that what he has discovered is a nest, nobody else is entitled to say nay. The Kingfisher is by no means an uncommon bird, and is very generally diffused over the country. We have met with it in Devonshire and also in Hampshire ; in the latter county, especially in the various creeks and arms of Southampton Water, it is even abundant, although it is never once mentioned, so far as we remember, in White's " Selborne." In the North of England it is also common ; and at Bolton in Lancashire we met with a factory operative, a thorough enthusiast in ornithology, and the owner of a very respectable collection of birds of his own mounting, who assured us that he regularly captured a dozen or more of them every season. His plan is to go early in the morning before day- light to some stream known to be frequented by the bird, and 204 CURIOUS SUPERSTITIONS. to suspend across it, in a suitable spot, the open mouth of a bag net made of fine silk ; then going along the stream, he beats the bushes to start the bird, which shooting along in the dim light, rushes into the net, and is securely bagged. A curious superstition has long obtained that if the stuffed skin of the Kingfisher be suspended by a thread to the ceiling of a room, however closely shut up, it will yet turn its bill weathercock wise to the quarter whence the wind blows. Hence honest Kent, in " King Lear," in his rage against the insolent steward, declares that " Such smiling rogues as these * * * * * Renege, affirm, and turn their halcyon beaks With every gale, and vary of their masters ;'' and again Barabas, in Marlowe's " Jew of Malta," says : " But now, how stands the wind ? Into what corner peers my halcyon's bill ?" It appears that this superstition still keeps its ground in some parts. Charlotte Smith tells us that she has once or twice seen the Kingfisher hanging thus as a weathercock from the beam of a cottage ceiling. It has lately been seen suspended for the same purpose at Botley near Southampton ; where some of the country people also believe that if a dead Kingfisher be sus- pended by its bill, it will regularly turn its breast to show the ebb and flow of the tide. The Corvidce, or Crow family, are far better known than liked, although, as we shall find, that much may be said in their favour. Very few people, it may be presumed, need the help of good Mrs. Ford " to know Turtles from Jays" of the non-figurative kind, though it is not at all unreasonable to suppose that there are many who would fail to recognize in the gaily-coloured Jay of the ornithologist (Corvus glandarius), a confrere of the sable fraternity above mentioned. One of the Crows, however, the Jay undoubtedly is, and a near ally of the Jackdaw (C'orvus monedula), which, as Cowper reminds us, is " A great frequenter of the church, Where, bishop-like, he finds a perch, And dormitory t^o ;" HABITS OP THE MAGPIE. 205 but between this zealous church-goer and the wood-haunting Jay, stands that Ishmael of the feathered tribes, the Magpie ( Cor v us pica), which, harassed and persecuted by almost every- body, repays his ill-usage by wholesale depredations and a sort of instinctive love of mischief. It is rather a suggestive circum- stance, however, that in Norway and Sweden, where this bird is extremely common, and is taken great care of by the people, it bears an opposite character. In Norway especially, where it is a great favourite, it has little of the sly cunning and suspicion which it exhibits with us, and lives on the most familiar terms with the inhabitants, picking up its food at their doors and frequently entering inside their houses. With us the Magpie has certainly a most unamiable reputa- tion. It seems to be equally fond of animal and vegetable food, now helping itself to the newly-sown grain or the gardener's fruits, and now sharing with the Rooks their grubs and worms. But no sort of animal food comes amiss ; and most ruthlessly does it go to work to gratify its appetite. It storms the nests of small birds, and robs them of their eggs and young ; it carries off the young broods from the poultry yard and the game pre- serves; it attacks young hares and rabbits; and at times will even attempt the destruction of lambs and weakly sheep, first plucking out their eyes. But with all this truculence and rapacity, the Magpie has still a tender place in its heart. Game- keepers know well that when once they are in possession of its young the old birds may easily be lured to their own destruction. The nest of the Magpie is a very bulky affair, constructed of small branches and twigs interlaced together, generally placed high up on some tree-top where few people having a regard for their necks care to venture, how light soever they may make of the wise saw which avers that no good ever comes to man or boy who takes a Magpie's nest. It does sometimes happen, however, that where high trees are few and far between, the Magpie will build in low bushes ; and Bishop Stanley tells an interesting story of a pair of these birds, which, in a remote and barren part of Scotland, had for several years built their nest and brought up their young in a gooseberry bush. But perfectly conscious of the dangers to which they were there exposed, they barricaded not only the nest, but the bush itself, all round with briers and thorns firmly entwined together, and nearly a yard in thickness ; 206 JACK AT CHURCH. and every spring they carefully repaired their fortress, using for the purpose rough, strong, prickly sticks, which sometimes re- quired the assistance of both the birds together before they could be adjusted in their proper places. In this way the nest was surrounded with such a formidable chevaux-de-frise as to be secure not only against the attacks of foxes, cats, hawks, and other predatory creatures, but even of more important foes, for without a hedge-knife, bill-hook, or something of the sort, even a man would have had great trouble to get at the young. We must not conclude our account of the Magpie without some notice of its imitative and loquacious powers, and of the ridiculous use to which it sometimes turns them. A book might be written on the subject ; but one story must suffice for us here. It is pleasantly told by the writer of a series of most agreeable papers on birds in " Eraser's Magazine " for 1857, and pertinently illustrates the truth of Sydney Smith's observation, that what- ever powers of oratory a parson may possess he loses all com- mand over his audience the moment a bird makes its appearance in the church. It was certainly the case when Jack, a Magpie well known in the village of , in the county of Kent, for his mischievous propensities, entered the village church in the afternoon of Sun- day, July 25th, 1852, during the time of divine service. The rogue hopped quietly in at the open door, and for a time sur- veyed the congregation, recognizing many a friend who was wont to greet him with words of kindness and familiarity ; but upon this occasion Jack was surprised at finding that no notice was taken of him. At last he seemed determined that he would not be thus overlooked, and down the middle aisle he marched, knock- ing at the door of each pew, and announcing his presence with a clear, loud " Here am I !" This move had the desired effect, for in a very few moments every eye was turned upon our hero. The worthy parson finding himself in a decided minority, and perceiving broad grins coming over the before solemn faces of his flock, at once stopped the service, and desired the clerk to eject the intruder. But the order was more easily given than executed. Jack was determined not to leave, and so, finding himself pursued, took refuge in a forest of legs belonging to his young friends the school children, who did not appear at all un- willing to give him shelter. The clerk rushed on, intent upon BIRDS OF SONG. 207 catching the enemy, and putting an end to this unorthodox pro- ceeding, and over first a bench and then a child he stumbled in his attempts to pounce upon the fugitive, who easily evaded his grasp, and always appeared just where the clerk was not, in- forming him ever and anon of his whereabouts by the old cry " Here am I !" At last, with the help of two or three of the con- gregation who had joined in the pursuit, a capture was effected, and Jack was ignominously turned out and the door closed upon him. After the lapse of a few minutes, order and solemnity were restored in the church, and the prayers were re-commenced and ended without further disturbance. The parson in diie time ascended to the pulpit, gave out hia text, and commenced his discourse. But he had not proceeded far when he was interrupted by a loud noise accompanied by rapping at the little window at the back of the pulpit. Turning round to ascertain the cause, he saw friend Jack pecking away at the window, flapping his wings against it, and screaming at the top of his voice " Here am I!" " Here am 1 1" a fact which no one could gainsay or resist laughing at. The worthy parson, finding his own gravity and that of his congregation so entirely upset by what had occurred, brought his sermon to a speedy con- clusion and dismissed the congregation. Poor Jack had sentence of death recorded against him, but upon the petition of a number of the parishioners, his punish- ment was commuted to banishment for life from the scene of his crime. The family of Finches introduces us at once to the song-birds ; and with them comes that much debated question, what is the special motive that prompts our little feathered friends to the ex- hilirating strains with which they greet us when spring comes round with its blue sky and bright tinted flowers? It has very commonly been argued that these bursts of song are due almost entirely to the exercise of the imitative faculty in birds ; but we are inclined to think that this is a veiy insuffi- cient explanation of the matter. No doubt the natural and, as we should say, instinctive notes of birds may be greatly modified, or even altogether changed, by education, especially when man himself directs the process and entirely alters the conditions under which the young birds attain to maturity. The Hon. Paines Ban-in gt on tried several experiments with the view of 203 EXPERIMENTS IN SONG. ascertaining how far this change of song might he effected, and the results at which he arrived certainly show that the influence of education is very great. Thus he tells us that he educated nestling Linnets under the three best singing Larks, the Skylark, Woodlark, and Titlark, and in each case the young birds adhered entirely not to the song of the Linnet but to that of their instructors. Jn the case of the Linnet that had learned the Titlark's song, he tried if the note could be again changed, for this purpose leaving the bird in a room with two common Linnets which were in full song, for four months ; but not a passage was borrowed from the new in- structors, the Titlark-Linnet continuing steadfastly to the song that it first learned. Other cases are mentioned that of a Linnet which learned the song of an African Vengolina so per- fectly that it was impossible to distinguish the song of the teacher from that of the taught of a Goldfinch that learnt of a Wren of a SparroV that acquired the joint song of the Linnet and the Goldfinch and of a Redcap that studied under a Nightingale. In this last case, however, the learner was not so apt as some of the others ; for after at first breaking down he ultimately sang three parts in four of the song of the Nightingale, and the rest what the bird-catchers call rubbish, or no particular note what- ever. Mr. Barrington states that to be certain that a nestling will not have even the call of its species, it should be taken from the nest when only a day or two old, because, though the young birds can- not see till the seventh day, they can hear from the moment they are hatched, and that as the call-note of the parents announces the arrival of food, that would be the first sound the young birds would learn. He also admits " that a great deal depends upon circumstances, and perhaps caprice in the scholar," and that no general rule or inference can be laid down as to the result of such experiments. The most remarkable cases of variation as the result of training are those in which the young bird acquires, not the song of another bird, but fragmentary snatches of human speech. A case of this sort is mentioned by Mr. Barrington, in which a Linuet which had been taken from the nest when only two or three days old, learned almost to articulate the words pretty loy, w'thout acquiring either the note or the call of any bird whatever* A TALKING CANARY. 209 A far more interesting case of this kind, however, has recently been recorded by Mr. Leigh Sotheby. In this instance the bird was a Canary, the only one hatched out of a nest of four eggs, and which, for some cause or other, was immediately deserted by its parents, who commenced a new nest upon it. On being re- moved from the cage, where it was found half dead, it was care- fully pkced in flannel near the fire ; and after much attention it was fully restored to health and strength, and brought up by hand. It was entirely removed from all other birds, and seldom heard any sounds but those of the endearing epithets that were addressed to it by its fair protector. To the surprise and delight of the household, the first utterances of the little pet were those very expressions of endearment. When only three months old it repeated " Kissie, Kissie," and imitated the sound of kissing ; and after a while it would repeat for hours to- gether, " Dear, sweet Titchie, kiss Minnie ; kiss me then, dear Minnie ; sweet, pretty, little Titchie, Kissie, Kissie, Kissie, dear Tit- chie, Titchie, wee, gee, gee, gee, Titchie, Titchie," frequently string- ing together these particular expressions, and repeated them over and over again in rapid succession. Occasionally it imitated the sound of a dog- whistle used about the house ; and like a loyal subject it learned to whistle the first bar of " God save the Queen.'' The little creature was remarkably tame ; and frequently would hop down from its cage to its owner's finger, shouting and talking the while in the most excited manner. Whatever force there may seem to be in facts like those we have given, as tending to show that birds have no innate ideas of the notes which are supposed to be peculiar to each species, their value in the argument is greatly diminished by a consideration of the circumstance, that it is only in exceptional cases, and under what we may call unnatural conditions, that they occur at all. Moreover, it seems difficult on the theory of imitation to under- stand how birds should have any distinctive notes at all, and why it is that the individuals of each species exhibit such a constant general uniformity in their song. But the theory is contradicted by the fact of every-day experience. Nothing is more common than for young Thrushes, Blackbirds, and Larks, not to mention other birds, to be taken from the nest within a few days of their being hatched, and to be brought up by hand in towns far away from the green fields and the songs of their fellows, and P 210 LOVE AND RIVALRY. yet these birds eventually burst out into song, each in the peculiar notes of its race, so as not to be distinguished from those in a wild state. But granting it to be the most reasonable supposition that song in birds is thus instinctive and untaught, it still becomes a question what may be the particular motive which incites to the performance ; and on that point considerable diversity of opinion prevails. The general opinion seems to be that love, and the rivalry to which it prompts, are the two great stimulants to which we owe the concert of sweet sounds with which the air is rilled in spring and early summer. " I lay it down as a maxim in ornithology," says White of Selborne, " that as long as there is incubation going on there is music." Pennant advocates the same view of the subject, and mentions, that as the principal cares of life fall to the lot of the female bird, the male is endowed with the faculty of song that he may alleviate her fatigues, and cheer her with his inspiriting lays the while she is discharging her parental duties. Montagu is another naturalist of eminence who supports the same opinion, and he particularly instances the Nightingale, which in the first place vies with its com- panions, both in song and fight, to win a partner, and then ever after attends her with the greatest assiduity, and constantly regales her with his song. That rivalry amongst the males of singing birds has much to do with their outbursts of song, there can be no reasonable doubt ; but whether mere joyousness and gaiety of heart be not a more probable motive than the special one of love may at least, we think, admit of a doubt. It should be borne in mind that the female bird is by no means destitute of song, although her partner always greatly excels her in that accomplishment. Neither is it true that song birds generally sing only during the seasons of pairing and rearing the young. With the hard-billed, seed- eating birds this is no doubt true, but with the soft-billed birds it is far otherwise. Most of these birds leave us in the autumn for the sunnier skies of the south ; although when they nre detained with us in cages or aviaries, they continue in song all the year. Moreover, those which remain with us the year through, the Hobin and the Wren, for example, sing throughout the winter, not even excepting times of severe frost, as we can vouch from our own observation. COCK ROBIN AND JENNY WREN. 211 On the whole, therefore, we incline to the opinion that " The sound of music sweet From birds among the bowers," which greets us in the young prime of the year is called forth, not so much by love, as by a general and all-pervading gladness and gaiety of heart. But the Robin and the Wren, those old traditional friends of our childhood, are not to be passed by with the bare mention of their names, familiar though they are, and pretty well known bj everybody. Naturalists may say what they please, but Cock Robin and Jenny Wren are man and wife all the world over, married and made one ages ago, and with a bond so sacred and indissoluble that Sir Cresswell Cresswell, would find that it quite overtopped his capacity to cut it asunder. Hath it not oft been said or sung that " The Robin and the Wren Are God's Cock and Hen ;" and in awe of the terrible malediction that guards their domicile from violence, does not the truant schoolboy keep his hands off from the nests of both the one and the other ? Izaak Walton says that " honest Robin loves mankind, both alive and dead," and if the veracious history of the Babes in the Wood will suffice to verify the latter part of the assertion, we shall be at no loss to find proof of the former. But strangely enough White of Selborne who almost invariably writes in a genial and kindly tone, seems to have a positive antipathy to the Robin, and speaks of it most disparagingly. He notices it but once, and then very curtly ; and concludes what he has to say with the ungracious remark that, " notwithstanding the prejudices in their favour, they do much mischief in gardens to the summer fruits." " Pert and spruce Master Robin," as Graham calls him, was evidently no favourite with the recluse of Selborne ; and it must be confessed that he exhibits at times some very unamiable qualities. His pugnacious and quarrelsome disposition is well known, and we have sometimes seen one of the little fellows i'earlessly attack a crowd of Sparrows that have come to share his daily allowance of crumbs, and fairly drive them off. It is not always, however, that he succeeds in these onslaughts, for occa- 212 THE WATER OUSEL. sionally some of the Sparrows show fight in return, and oblige their assailant either to share the provender with them or to retire from the scene altogether and leave them in full possession. True to the life is Thomson's picture of the Robin when he first ventures inside the cottage door to pick up his allowance of crumbs : " Then hopping o'er the floor, Eyes all the smiling family askance, And pecks, and starts, and wonders where he is." These familiar habits of the Eobin, combined with its sprightly airs, have made it a general favourite wherever it is known, and have thus procured for it in almost every coimtry of Europe some familiar and endearing epithet. The Eobin is in truth the first and most friendly of all our feathered friends. One of the most curious of our song-birds is the Dipper, or Water Ouzel (Cinclus aquaticus), which, although closely related to the Thrush and Blackbird, is almost as much an aquatic bird as any of those properly so called. It is always found in the immediate neighbourhood of water, and delights especially in the clear and rapid streams of mountainous districts, where it is commonly to be seen perched upon some block of stone rising from the centre of the current, perpetually dipping its head and jerking its tail much after the fashion of the little Wren. "I do not know," says Mr. St. John, " among our common birds so amusing and interesting a little fellow as the Water-ouzel, whether seen during the time of incubation or during the winter months, when he generally betakes himself to some burn near the sea, less likely to be frozen over than those more inland. In the burn near this place there are certain stones, each of which is always occupied by one particular Water-ousel : there he sits all day with his snow-white breast turned towards you, jerking his apology for a tail, and occasionally darting off for a hundred yards or so, with a quick, rapid, but straightforward flight ; then down he plumps into the water, remains under for perhaps a minute or two ; and then flies back to his usual station." There has long been a dispute as to the precise behaviour of the Dipper during the time which it thus passes under water. On the one side it is maintained that the bird nms about at the bottom of the stream, much as it might do on dry ground ; while on the other side it is contended that such a procedure is AN IMPOSSIBLE PERFORMANCE. 213 absolutely impossible, and that the bird merely dives and swims xinder water like other aquatic birds. In a question of this sort, the point at issue is to be decided not so much by the results of casual observation, in which from the very nature of the case all are liable to error, as by an appeal to the invariable laws of nature. Still, what ought to be, and even what must be, has to give way when con- fronted with a clear and indisputable case of what is; and on this question it must be admitted there is what looks like very reliable evidence of the impossible performance. Here, for example, is Mr. St. John, who affirms in the most positive manner that he has himself seen the Dipper walk deliberately off from his stone down into the water, and walk and run about on the gravel at the bottom, scratching with his feet among the small stones, and pecking aay a t all the small insects and ani- malculse which it could dislodge. " On two or three occasions," he continues, "I have witnessed this act of the Water-ousel, and have most distinctly seen the bird walking and feeding in this manner under the pellucid waters of a Highland burn." Against this testimony of Mr. St. John's there is that of Mr. Macgillivray, an equally careful observer, who also speaks from personal observation. He says distinctly that in one or two instances where he has been able to perceive the bird under water, it appeared to tumble about in a very extraordinary manner, with its head downward, as if pecking something, and at the same time making great exertion with both legs and wings. The general direction of the body was obliquely downwards, and the exertions the bird was making were evidently to counteract its natural buoyancy and to keep itself at the bottom. Mr. Mac- gillivray says, indeed, that the movements of the bird under water are precisely similar to those of the Divers, Cormorants, and Mer- gansers, which are effected by the joint action of both wings and legs, and are rather to be described as flying than as bond fide swimming ; and he further states that the bird does not proceed to any great distance under water, but, alighting on some spot, sinks, and soon reappears in the immediate neighbourhood, when it either dives again, or rises on the wing to drop somewhere else in the water, or to take up its favourite position on some in- sulated stone in the middle of the brook. In so far as observation is concerned, therefore, there are 214 THE HOUSE SPARROW. authorities both for and against the subaqueous pedestrianism of the Dipper. But it is not to be forgotten, that in order to per- form the alleged feat, it is necessary that the Dipper should have the power to overcome the effects of gravitation, which the moment the bird ceased its active exertions to keep below, would force it to the surface of the water ; and as no such power is known to us, it is only reasonable to infer that Mr. St. John, and those who agree with him, are mistaken as to what they saw, and that the Dipper performs no such inexplicable feat as that which they have ascribed to it. The Incessores or Perching Birds, with which we are now deal- ing, are also known as the Passerine or Sparrow-like Birds, the common House-sparrow (Fringilla domestica") being thus the model or type of the entire order. A word or two, therefore, for the House-sparrow. " A village without Sparrows," says Mr. Magillivray, " has as desolate an aspect as a house without children," though unfortunately for the world the one is much less rare than the other. The boldness and impudence of the Sparrow is familiar to everybody ; and Douglas Jerrold somewhere notices the arch and inquisitive way they have of looking down from the house-tops at people who find their way home to the street-door in tho small hours of summer mornings, when they are themselves just beginning to wake up for the day. There is quite an air of banter about them at such times ; and the hoarse chirp with which they greet you sounds very much as though they said, " Oh, oh ! Mr. Jones ; and where have you been ? and what will Mrs. Jones say ?" One can almost see their elevated eyebrows as they poke their fun at you ; and the fluffy shuffle with which they accompany it shows that they enjoy the joke immensely themselves. In affection for its young there are few birds which surpass the Sparrow, and many interesting cases are recorded of its devoted attentions. In one instance a pair of Sparrows continued to bring food to the nest some months after (he young brood had left it ; a ladder was placed against the wall to ascertain the cause of this unusual proceeding, when a full-grown bird was found in the nest, where it was kept prisoner by some thread in which it had got one of its legs entangled. And Mr. Jesse mentions a case in which a farm-servant having placed a nest of young Sparrows iu A lX)MEStIC TRAGEDY. 215 a trap cage, caught no less than forty old birds, all coming with food in their mouths to feed the helpless nestlings. But the Sparrow will even go beyond its own species in rendering its kind offices ; and there is a well-known story of one which picked up an acquaintance with a Canary that was hung up in its cage amongst some trees in a garden at Chelsea. The ac- quaintance began one morning with the Sparrow dropping a worm into the cage for the Canary, and after a while it became so intimate that the Canary would take the dainty bits directly from the bill of his generous friend. The fame of this bene- volent Sparrow soon spread abroad, and other Canaries were hung in adjoining gardens to share in his attentions ; nor were they put there in vain ; for he visited them all, though his first and longest visit was always paid to his old acquaintance. But that incident of the young bird tied to the nest by its leg reminds us of another and much more serious mishap which once befel a Sparrow, the story of which is quoted by Mr. Yarrell from the " Illustrated London News." Those who know the Rotunda in Sackville Street, Dublin, will remember the richly carved frieze, representing the heads of oxen and festoons of flowers, which runs around the centre building and forms its principal external ornament. In the hollow of the eye of one of the heads a Sparrow built his nest, and amongst the materials composing it there chanced unhappily to be a woollen thread with a noose at one end of it. By some means the poor bird got his head inserted in the noose ; and in his eiforts to extricate himself, he fell from his nest and hung himself by the neck. lie was observed for a while making desperate efforts to escape, but in vain ; the mishap put a period to his career, and for some time his remains were to be seen gibbeted at his own door, and flut- tering in the wind, while the straws of the nest projected from the eye-hole above his head. No bird is more familiar than the House-sparrow, though v. e fear there are few persons who would be much disposed to give it a place amongst their feathered friends. But there is reason to hope that better days are coming, not merely for Sparrows, but for the feathered tribes generally. It is beginning to be understood that the entire race of birds have a work to do which is of vast importance even to man himself, and that his interests are best promoted, not by their wholesale destruction, but by their 210 BIRD BENEFITS. being allowed, with as little interference as possible, to discharge the various offices for which they are specially designed and qualified. The petition presented some time since to the French Corps Ldgislatif, requesting that steps might be taken to preserve the birds which subsist on insects injurious to agriculture, has excited great attention, not only in France, but throughout Europe, and there can be no doubt that the many striking facts which it contains will open the eyes of our agriculturists to the fact that in slaughtering the insectivorous birds they have really been destroying their best friends. In this instance, as in many others, it will be found that an enlightened self-interest is in per- fect keeping with the most humane and careful regard for what, if we only knew them better, we should universally regard as our Feathered Friends. 217 CHAPTER X. "LIVE LIONS," PAST, PBESEKT, AKD FUTUBE. " \Vee have also pai-kes ami enclosures for all sorts of boasts and birds which wee vse, not only for view or rarenesse, but likewise for dissections ; that thereby wee may take light what may bee wrought upon the body of man." THE good time coming foreshadowed by Lord Bacon in that re- markable fragment the "Xew Atlantis" is gradually drawing nigh. Our various scientific and philosophical societies give us an almost exact realization of the ideal " Soloman's House," with its different means and appliances for ascertaining the " causes and secret motions of things, and the enlarging of the bounds of Humane Empire, to the effecting of all things possible ;" while the united gatherings of their members at the meetings of the British Association, correspond precisely with those " circuits or visits of diuerse Principall Citties of the Kingdorne" when new inventions and discoveries were made public. In respect to actual achievements we have of course still to discover the " Water of Paradise," " souereigne for health and prolongation Oi life ;" and with all our skill in horticulture we still fall short of making "diuerse plants rise by mixtures of earthes without seeds," and of making one " tree or plant turne into another." But with the exception of conceits like these, which the progress of knowledge has exploded, we have already in a thousand ways far outstripped the boldest imaginings of the great philosopher. In respect to the study of Natural History the " preparations and instruments of Soloman's House are pretty much the same as we have ourselves. The " particular pooles, where wee make trialls upon fishes," are fairly represented, no doubt, by the Aquarium, with a little advantage perhaps on our side. And so with respect to " parkes and enclosures for all sorts of beasts and birds," excepting that in this case the end we propose stops short of the lofty purpose suggested by Lord Bacon, and relates mainly 218 DEATH OF A FAVOURITE. to the gratification of curiosity and the enkrgement of our know, ledge of the animal creation. It so happens, however, that although none of the animals exhibited in our Zoological Gardens are obtained with a special view to " dissection," there are very few of them, after all, that escape the knife at last. No sooner do they cease to be of service for " view," than there are a dozen or more Fellows and Professors eager to have a hand in them, and sometimes the disclosures which are thus made are not a little curious. For example, there was Tom, the favourite Seal in the Regent's Park Gardens : nobody could conjecture at first what it was that had shortened his days, and deprived the Gardens of cue of their greatest attractions. But when the poor fellow came to be dissected, it was found that the coats of his stomach were bristling with fish-hooks ! The reader may be sure that not only Tom's successor in the Seal pond, but all the icnthyophagi of the establishment h|ive benefited by the discovery, and that no fish arc now served out which have not first been carefully freed from cold steel. The Regent's Park Gardens have long been a favourite resort of ours, and there are few places where the student of Natural History can gratify himself with the sight of so many of the living curiosities of animal life. Holiday place as it is, therefore, we may well pay it a visit, and look for a while at some of its more curious and interesting occupants; not confining ourselves to those of the present time merely, but remembering our high distinction of "looking before and after," recalling for a time some of the " lions " of days gone by, and anticipating the pro- bable " lions " of the future. The Fish House, which contains more wonders than all the rest of the Gardens together, we may dismiss very summarily. Not a sentence need be spent on the Anemones, Serpulie, Hermit Crabs, and their allies, though the cases containing them are at all times besieged by an eager crowd of visitors anxious to make acquaintance with these little dwellers in the deep. In the fresh-water tanks no fish attracts more attention than that ruthless fellow the Pike, which rests so quietly that it looks like a painted fish in a painted Aquarium, although pining apparently for the still shady coverts in which it delights to nestle by the pool or riverside. Not that ths fellow very readily succumbs to the effects of confinement ; for one of them has lived THE PHYSICIAN OF FISHES. 219 here in the Fish House for upwards of five years. The Jack are at all times a truculent race, and the specimens here in the tanks fully sustain the character blear-eyed, and sinister-looking as any that ever seized thirsty calf by the nose, ravaged a fish-pond, or made off with an angler's tackle. Neither in spirit nor in appetite do they seem to be much affected by their captivity. It is necessary to cover the tank containing them with a net to keep them from jumping over the sides at night ; and when feeding-time comes round, they are always ready, be the meal fish, or frogs, or birds, or, as is sometimes the case, a hall-grown rat. "We have seen it stated somewhere that a young Pike here, in the Fish House, having been maltreated by an elder of its own species, was completely cured of its ailments by the attentions of a couple of Tench. There can be little doubt, however, that it was a made-up story. The Tench has long had the reputation of being " the physician of fishes," as good old Isaak "\Valtuu expresses it, especially of the Pike, although there is no evidence whatever to countenance the wide-spread belief in its healing virtues. Mr. Couch, who is a great authority on all matters ich- thyological, is inclined to the opinion that it has originated from a passage in the " Chronicle " of Hollinshead, who, speaking of the Pike, says that, " when the fishmonger hath opened his side, and laid out his rivet unto the buier, for the better utterance of his ware, and cannot make him away at that present, he laieth the same againe into the proper place, and sowing up the wound, he restoreth him to the pond where Tenches are, "who never cease to sucke and licke his greeved place, till they have restored him in healthe, and made him readie to come again to the stall when his turne shall come about." And so, argues Mr. Couch, this nibbling of the fat of a wound that would have healed as well without it, has in all probability given rise to an opinion which naturalists, content to copy from each other, have perpetuated to the present time. Not long ago the Fish House just missed an addition to its live stock which would have proved a wonder of the first mag- nitude. It. was a fine specimen, three foot long, of the famous Fishing Frog or Angler (Lophius jntcatorius), which was captured near Weymouth, and at once sent off to the Gardens ; but unfortunately the journey was too much for it, and it made its appearance in the Fish House, dead. But such a "lion," 220 ANGLING EXTRAORDINARY. even though a dead one, was not to be thought lightly of; and so long as the olfactory nerves of the visitors were able to endure it, the monster was made to display his strange proporiions. The Angler well deserves the name of Wide Gab, by which it is known to the fishermen north of the Tweed, for surely never was another such a mouth seen either in bird or beast or fish. This re- markable fish has much the appearance of a huge Tadpole ; its head being of enormous size, measuring across the widest part more than the entire length of the animal, while its body tapers away to a tail of the most modest dimensions. The most remarkable character of the creature, and the one which has suggested the name of " Angler," is the presence of two long, slender, and flexible appendages which spring from the top of the nose, and are dilated at the extremity into a glittering silvery expansion, that acts as the bait with which the monster attracts his unsuspecting prey. It goes to work in a very wary and sagacious fashion, crouching close to the ground, and then by the action of its pectoral fins stirring up the sand or mud. Hidden by the obscurity which it has produced, it elevates its fishing-rods, moves them in various directions, and twiddles about the shining baits at the extremity ; the small fish in the neighbourhood, attracted by the moving objects, come close to examine or seize them, when the monster springs iipwards with his cavernous mouth wide distended, and in a moment they are gone. There is no mistake about it, that if an ogre of this sort could be neatly caged in the Fish House, and induced to go through his performance in presence of the visitors, it would be the most successful "hit" the Zoological Society had ever made. And yet not the most successful perhaps after all, for here is another, and withal a more practicable one. What would you say now to a Singing Fish ? It is true we have lately had a " Talking Fish ;" but that was a mere hoax, the so-called " fish " being a seal, and the " talking " a mere unintelligible and only occasional bark or grunt. What we propose is a real bond fide vocalist belonging to the finny tribes. It would take immensely. Singing Mice and Talking Canaries have had their day ; but a Singing Fish ! Mr. Edward Newman has an interesting paper on the subject ofthese Mxisical fishes of the East in the " Zoologist " for last year ; MUSICAL FISHES. 221 and lie brings together a variety of evidence in proof of the opinion that such piscine vocalists do really exist. Sir Emerson Tennant, Dr. Buist, and other persons who have actually heard the performance are brought forward as witnesses ; and from the accounts they give it would appear that in all probability there are several species of fish that are gifted with these vocal powers. One of them is described as producing a sound like the gentle thrills of a musical chord, or the faint vibrations of a wine- glass when its rim is rubbed with a wet finger, not one sustained note, but a multitude of tiny sounds, each clear and distinct in itself, the sweetest treble mingling with the lowest bass. An- other is said to make long, distinct sounds like the protracted booming of a distant bell, the dying cadence of an .^Colian harp, the note of a pitch-pipe or pitch-fork, or any long drawn-out musical note. A third species produces a loud, monotonous, singing sound, which rises and falls and sometimes dies away, or assumes a low, drumming character. There is obviously no lack of variety in the vocal accom- plishments of these oriental fish ; and if the Zoological Society would only set to in earnest to procure a good chorus of them, it would not only put an end to the scepticism with which some old-fashioned people still persist in regarding the story, but afford to the world a new musical entertainment of a character that no one had ever dreamt of before. On the banks of one of the ponds devoted to the Water-fowl we come across a fine specimen of that little aquatic beauty, the Mandarin Duck (Aix galericulata), which, decked out in his bridal attire, is sitting placidly amongst the grass while Mr. Wolf or one of his brother-artists takes his portrait. It is well worth taking, for this bird is the very prince of ducks, and is celebrated for the elegance and conspicuous beauty of its plu- mage. It is the male alone, however, which is thus adorned, and in this respect it affords a capital illustration of that almost uni- versal law of nature, that when in the matter of adornment there is any difference at all between the sexes, the gaiety and show is all on the part of the males. In respect to the Man- darin Duck this difference is very obvious, for while the lady is plain and unadorned to a fault, the gentleman comes out in flam- ing colours, and is the observed of all observers. But let there be no mistake about it ; this resplendent livery fs put on after 222 A DEVOTED COUPLE. all solely with an 63-6 to the lady ; and the love season over, the gentleman at ones begins to doff his gay attire, and soon appears in the same unassuming russets and grays as his bride. The manners of this beautiful bird are remarkably gentle and loving. Once mated, they are mated for life ; even in confine- ment they constantly move about together ; and the death of one gives rise to the most obvious and unmistakable signs of grief in the other. Dr. Bennett in his " Wanderings " tells a story of a loving couple, in which this mutual attachment was very strik- ingly exhibited. The beautiful drake was stolen one night, while his less attractive partner was left behind. The following morn- ing the poor duck was seen in a retired part of the aviary brood- ing and disconsolate, evidently sorrowing over her loss. Whilst in this condition a gay and prim drake whose partner had been accidentally killed net long before, made up to the disconsolate duck, and made a thousand endearing overtures. But it was all to no purpose ; the duck refused all his offers, and moped and brooded still ; she neglected her food ; her plumage became ragged and dirty ; and she Avas evidently fast falling a sacrifice to conjugal fidelity and affection. But after about three weeks had passed the stolen drake was recovered and brought back. He no sooner recognized the aviary in which he had previously lived, than he quacked vehemently and clapped his wings with delight. His partner received him with the greatest joy : they quacked in concert, crossed necks, bathed together, and were perfectly happy. But mark the sequel. The happy pair had not long been reunited before the recovered drake furiously attacked the too attentive widower, pecked out both his eyes, and left him so maimed that he died within a few days afterwards ! In China the Mandarin Duck is regarded as the symbol of conjugal fidelity, and as such is usually carried in their marriage processions; but whether the newly married couple invariably learn the lesson which is thus emblematically set before them may be open to question. But certain it is that the Chinese attach the highest value to the bird, and it is with the utmost difficulty that specimens can be obtained by foreigners. Not Jong since, indeed, a gentleman, writing to China for a pair of the birds, got as his reply, that in the present disturbed state of the country it would be much easier to procure a pair of Man- darins than a pair of Mandarin Ducks ! THE ANCIENT PHCENICOPTERUS. 223 Not far off from the green and bowery pond in which these happiest of ducks pass their days is the Old Aviary, in which aro several birds well worth the attention of the visitor to the Gardens, and deserving of at least a passing notice here. In the first place here are the beautiful Curassows from Central aiad South America, which are one day to grace oxir poultry yards and sup- ply us with an additional and most delectable dish for the dinner- table. Here again stalks about, with his quills behind his ears, that singular compound of wader and bird of prey, the Secretary Bird, the Snake-eater of Southern Africa. But more attractive than all besides, here also is a group of those extraordinary birds, the Flamingoes, which form an unmistakable " link" be- tween the waders on the one hand and the true web-footed birds on the other. To the ancients the Flamingo was the Phceuicop- terus, the bird with " wings of flame," the name alluding to the gorgeous meteor-like appearance presented by the birds when winging their way through the air. But the acquaintance which the ancients had with the Fla- mingo was by no means con6ned to this far-off knowledge : they were familiar with it on the table, and though the flesh of the bird seems only occasionally to have been eaten, the brains and the tongue were ranked amongst the greatest luxuries. The tongue especially was held in great esteem ; and Pliny preserves the memory of one Apicius, whom he characterizes as " the most riotous glutton and belly -god of his time," as the individual who first taught the world that "the tongue of Phcenicopterns was a most sweet and delicate piece of meat." The Keptile House has a peculiar interest from what we know of the frightful powers of destruction possessed by many of its apparently insignificant occupants ; and, inside its doors, one is apt to look with some degree of concern at the glass fronts of the different cases. These slim-looking fellows, at rest upon the sand, or bathing in the troughs of water, are all very well at a safe dis- tance, but we decidedly prefer not to have them at close quarters. One thinks of the terrible occurrence which took place here a few years since, when one of the keepers, a man in the prime of life and full health, perished within an hour from the bite of a Cobra not larger than a common eel. But besides these smaller species of the Serpent tribe which kill their prey by means of poison-fangs, there are hero also the 224 AN INCUBATING PYTHON*. huge Pythons or Boas, which overcome their prey by mere mechanical pressure, first seizing the victim with wide-spread jaws, and then, witli the rapidity of thought, throwing the folds of their vast bodies round and round it, crushing rib and limb within their terrible embrace, and relaxing the coil only when life is extinct. One of these monsters is just now while we write attracting great attention from the novel spectacle it affords of an enormous serpent engaged in the interesting business of incubation. The animal in question is a splendid Eock Snake of India (Python molurus), twenty-two feet in length, and weighing nearly a hundred and thirty pounds. On the night of Sunday, the 12th January, she produced a string of leathery eggs, about the size of those of a goose, numbering in all upwards of a hundred. The Pythons are distinguished from all other reptiles by gathering their eggs into a group and covering them with their bodies, which is precisely what the lady Pythoness here in the Reptile House has done. She has wound herself up in a magnificent coil over her eggs, and there she has lain almost motionless and without food from the night of their extrusion. It is to be hoped that her maternal solicitude will in due time be rewarded by the appearance of a brood of young Pythons ; though as some of her eggs are known to be already putrid, it is much to be feared that her trouble will be all in vain, and her hopes of a family disap- pointed. The back of the Reptile House is generally occupied in part by some of the rarer and more valuable animals for which appro- priate accommodation is not to be had elsewhere. Here, for ex- ample, lived the baby Chimpanzees, and the famous Ant -Eater ; and here, at the present time, are specimens of the Lepidosiren, already alluded to, of those huge Bats, the Flying Foxes, and the Sicboldia, the Gigantic Newt of Japan (Sieboldia maxima), which properly should now be playing the part of first " lion," only that it has an unmistakable repugnance to the profession, and persistently hides itself away in a corner of its case. With all its faults, however, as a professional character, the Sieboldia is a most interesting fellow, and deserves far more at- tention from the public than he is likely to get. It is the largest of all existing Batrachians, and measures upwards of three feet in length. A native of the mountain-lakes of Japa-n, this is the GIGANTIC SALAMANDER. 225 first specimen that has ever reached Europe alive. It is. a most ungainly looking beast, with a broad flattened head, a vertical fin-like tail, and a warty scrofulous skin mottled over with black and brown. The uninitiated public seem to be a little perplexed at finding it in water ; and from hearing it spoken of as a Sala- mander, seem to have a confused notion that the proper place for it would be a good roasting fire. One lady, who was evidently mystified in this fashion, remarked to a companion, as we stood by, that she thought it was " extremely doubtful about its going through the fire," but as she was by no means clear on the point, and would not commit herself, she wisely kept to what she could see, and finished up with the safe position, " It is in water now, at any rate." The tmth is, the Sieboldia is first cousin to our own little Water-Newt, being, like it, an aquatic Salamander, and having nothing to do, therefore, with the re- nowned little fire-eater whose marvellous history has already been given. To the geologist the animal is one of unusual interest. It is the nearest existing representative of the famous Homo D-iluvii Testis of Scheuchzer, who, having a kind of monomania on the subject of an universal deluge, was unwearied in collecting organic remains in support of his opinions. The discovery of this fossil Salamander was a perfect godsend to the poor enthusiast. He had no doubt whatever that it was a veritable anthropolite, the petrified remains of one of the accursed race that was swept away by the flood. It seems unaccountable now that such an opinion should have gained any currency amongst men of science, but Scheuchzer's own perfect confidence begat a like faith in others, and for many years this fossil skeleton of a Salamander was an European celebrity, and the great pillar of the popular faith in an universal deluge. It was left to Cuvier to determine the true nature of the animal whose remains had attracted so much atten- tion. The rounded head and the large size of the orbits of the eyes satisfied him that the animal was a Batrachian ; and when, in 1811, he obtained permission to work upon the stone contain- ing the far-famed remains, for the purpose of uncovering any bones which might be still hidden, he placed before the operators the figure of the skeleton of a Salamander ; and he relates with what pleasure they saw the bones corresponding to those in the figure make their appearance as the chisel chipped away piece after Q 226 1 CASE OF SUSPENDED ANIMATION. piece of the stone which had previously concealed them from view. Poor Scheuchzer's own bones had by that time well-nigh crumbled away, or one can almost fancy they would have rattled in their grave at this terrible exposure of his cherished Homo Diluvii Testis. But let us turn from the Gigantic Salamander and his pre- Adamite ally to that most extraordinary case of suspended animation, the Two-toed Sloth (Cholcepus didactylus), which quietly munches a piece of biscuit as he hangs back downwards in the cage close by. The Sloth is the only animal in existence which passes its entire time suspended in this manner from the branches of trees. " The Monkey and the Squirrel," says Mr. Waterton, to whom we are indebted for most of our knowledge of these animals in a state of nature, " seize a branch with their fore-feet, and pull themselves up, and rest or run upon it ; but the Sloth after seizing it still remains suspended, and suspended moves along under the branch till he can lay hold of another." It moves suspended from the branches, it rests suspended from the branches, and it sleeps suspended from the branches, and in fact it is upside down its whole life long. But it is only in that position that it can make itself at all comfortable, for while it is all but helpless on the ground, and is then properly a " sloth," up amongst the branches it is quite at home, and executes its various movements with great rapidity. Never, indeed, was misnomer more complete than in the case of the Sloth, having regard, that is, to its proper place and to its natural habits. Here is a picture of the animal in and out of his element, drawn from the life by Mr. Waterton : " One day as we were crossing the river Essequibo, I saw a large Two-toed Sloth on the ground upon the bank. How he got there nobody could tell ; the Indian said he had never surprised a Sloth in such a position before : he could hardly have come there to drink, for above and below the place the branches of the trees touched the water, and afforded him an easy and a safe access to it. Be this as it may, though the trees were not twenty yards from him, he could not make his way through the sand time enough to escape before we landed. As soon as we got up to him he threw himself upon his back, and defended himself in gallant style with his fore legs. ' Come, poor fellow,' said I to him, ' if thoti hast got into a AT HOME IN THE WOODS. 227 hobble to-day, tliou sbalt not suffer for it. I'll take no advantage of thee in misfortune. The forest is large enough both for me and thee to rove in. Go thy way up above^ and enjoy thyself in these endless wilds ; it is more than probable thou wilt never have, another interview with man. So fare thee well.' On saying this I took a long stick which was lying there, held it for him to hook on, and then conveyed him to a high and stately mora-tree. He ascended with wonderful rapidity, and in about a minute was almost at the top of the trees. He now went off in a side direction, and caught hold of the branches of another tree, .proceeding in this manner towards the heart of the forest. I stood looking on, lost in amazement at this singular mode of progress. I followed him with my eyes till the intervening branches closed in between us, and then lost sight for ever of the Two-toed Sloth." The Indians, it seems, have a saying, that when the wind blows the Sloth begins to travel ; the interlacing of the branches at such times no doubt making it much easier and safer to proceed from one tree to another. Extraordinary as are the structure and habits of the Sloth, it has never been made much of here in -the Gardens, and by the majority of the visitors is passed by as a thing of ordinary every- day experience. Not so was it, however, with his kinsman and near neighbour the Great Anteater, which was exhibited in the same building a few years since, anel which, as a bygone celebrity of the Gardens, merits a passing notice here. Being the first animal of the kind which had ever been brought to Europe alive, the Great Anteater naturally attracted much attention, and for a considerable time the anxiety to see it was something bordering on the ludicrous. It was not the easiest thing in the world, however, to get a sight of him, even when you had gone to the Gardens for the purpose. Like all strictly nocturnal animals, it spent the greater part of the day in sleep, a circumstance which the young lady visitors especially pronounced a " shame." It certainly was very provoking, and it is to bo hoped that in the event of another Anteater paying us a visit ho will be taught to comport himself in a more befitting manner. As it was you were pretty sure to find the animal asleep, coiled up upon its bed of straw in a corner of the cage, with a room full of excited visitors waiting its awaking. Everybody put r>.

GRANT, M.A. 65~ This volume aims at being representative of our best Sacred Poetry from the earliest consolidation of the language to the present time; and at giving, in concise notices, particulars of the Lives and Poetical Characteristics of the Authors. The latter purpose stamps it, amongst sacred selections, as well-nigh unique. Whilst in the speci- mens it will offer it will be as fresh and responsible as if it had no predecessor; it will gratefully take advantage ot the labours of former collectors. Excellence is its first con- sideration ; but where poetical claims are equal, it will give a decision in favour of the less known. It relies for distinctiveness and individuality upon the ground of offering, of things equally good and beautiful, not those which are most easy, but those which are most difficult of access of giving specimens of poetical piety from sources which have been unsuspected or overlooked. 12. THE FLOWER OF CHRISTIAN CHIVALRY. BY MRS. W. R. LLOYD, Author of " Pictures of Heroes," &c. &c. ff~ This Volume will portray the Character and trace the Lives and Labours of various Pioneers in the field of philanthropy of those whose earnest and well-directed efforts are now at maturity, and bearing rich fruit in the world of to-day. At home the story of the English energy and thoroughness of such a man as Granville Sharp will serve to throw the reader back to the stirring scenes and the gallant band who led " the forlorn hope " in many a social struggle and Christian enterprise now adding lustre to the grace and glory of the records of Christian chivalry. Abroad, the humane and self-sacrificing labours of such men as Abbe de 1'lCpee, Pinel, and Bernard of Menthon, will serve to exhibit phases of life which ennoble our common nature, and cast into the shade all differences of creed. These and other representatives of those who strove to develop some of tlie most beneficent ameliorations which mark the present day, will form the subjects of this work. The few here mentioned will suffice to indicate its scope and spirit. ** The Publishers are encouraged to present these carefully-edited Volumes to the Public by the great success which has attended their efforts In the publication of works of a somewhat similar nature at the same price. During the last three years upwards of- Two HUNDRED AND FIFTT THOUSAND COPIES of their miscellaneous 3s. 6d. Juvenile Books have been sold, and the majority of them remain in continuous demand. Guided by the suggestions of this experience, the endeavour will be, in the present Series of BOOKS WITH A MEANING, to unite in a high degree all the excellences, Literary, Artistic, and Mechanical, which can render it at once agreeable and valuable pleasing to the young, and a help to the old.

THE ENGLISH GENTLEWOMAN; OR, A PRACTICAL MANUAL FOR YOUXG- LADIES ON THEIR ENTRANCE INTO SOCIETY. Third Edition. Eevised and Enlarged by the Author. Fcap. 8vo, cloth, floral gilt edges, 4s. . " This work is intended chiefly for young ladies of the upper classes of English societ y. The object of the writer is, by tha experience of a life passed in those circles which con- stitute what is called ' the world,' to supply those who are entering into a new and busy sphere with some of the practical benefits of observation and reflection, to propound the elements of that species of knowledge which, contrary to other sciences, is usually ac- [uired by blunders and errors, the lessons of which are often received with mortification, ud remembered often with regret. This little book, which pretends to no deeper leurn- iig than that which the heart and the memory can impart, is therefore offered to the ounc; who are destined, not for the happy duties of an humble and narrow sphere, but or the arduous introduction into a career usually deemed mure perilous. It is for those \ho must live, more or less, in communion with the gay and the opulent, but who wish ' t<> live unspotted in the world." It is meant to resemble the warning voice of the nurse who sees the children of her care sporting on the bank of a sedgy pool, all green wi.h aquatic plants, and calls them to beware." Extract from the Preface. THE ENGLISH MATRON; OR, A PRACTICAL MANUAL FOR YOUNG WIVES. By the Author of " The English Gentlewoman." Third Edition. Eevised and Enlarged by the Author. Fcap. 8vo., cloth, floral gilt edges, 4s. "To recall the serious purpose of nn English Matron's life; to warn, advise, inform her; to stimulate her best aims ; to place even In solemn terms the miseries of failure, was the ol.jrrt <>! this work.

It is offered with earnest prayers for the well-being of tha young matron ; in all faithfulness, in all sincerity, to her is proffered such counsels as a mother would give to a beloved daughter entering on the all-important career of married life," Extract front ike rrrfuM to the Tkir
