PREFACE. r I ^HIS work was originally written to be delivered as a lecture ; but as its pages continued to multiply, it was suggested to the author by numerous friends that it ought to be published in book-form ; this, at last, the author concluded to do. This work, therefore, does not claim to be an exhaustive discussion of the various departments of which it treats ; but rather it has been the aim of -the author to present the more interesting observations in each department in as concise a form as possible. The author has endeavored to give credit in every instance where he has taken advantage of the labors of others. This work is not intended for that class of people who are so absolutely certain of the truth of their religion and of the immor- tality that it teaches, that they have become unqualified to enter- tain or even perceive of any scientific objection ; for such people may be likened unto those who, " Seeing, they see, but will not perceive ; and hearing, they hear, but will not understand." This work is written for the man of culture who is seeking for truth believing, as does the author, that all truth is God's truth, and therefore it becomes the duty of every scientific man to accept it ; knowing, however, that it will surely modify the popular creeds and methods of interpretation, its final result can only be to the glory of God and to the establishment of a more exalted and purer religion. All facts are truths ; it con- sequently follows that all scientific facts are truths there is no half-way house a statement is either a truth or it is not a vi PREFACE. truth, according to the law of non-contradiction. If, therefore, we find tabulated amongst scientific facts (or truths) a statement which is not a fact, it is not science ; but all statements which are facts it naturally follows are truths, and as such must be accepted, no matter how repulsive they may at first seem to some of our poetical imaginings and pet theories. We cannot help but sympathize with the feelings which prompted President Barnard to write the following lines, still we will see he was too hasty : " Much as I love truth in the abstract," he says, "I love my hope of immortality more/' * * * He maintained that it is better to close one's eyes to the evidences than to be convinced of the truth of certain doctrines which Tie regards as subversive of the fundamentals of Christian faith. " If this (is all) is the best that science can give me, then I pray no more science. Let me live on in my simple ignorance, as my fathers lived before me ; and when I shall at length be summoned to my final repose, let me still be able to fold the drapery of my couch about me, and lie down to pleasant, even though they be deceitful, dreams." * The limitations to the acceptance of truth that President Barnard makes is wrong ; for, as Professor Winchell has said, " we think it is a higher aspiration to wish to know ( the truth and the whole truth/ At the same time, we have not the slightest apprehension that the whole truth can ever dissipate our faith in a future life." f Let us " Prove all things and hold fast unto that which is good," recognizing the fact that " the truth-seeker is the only God- seeker."

WHAT SCIENCE CAN ANSWER. object of science is not to find out what we like or what we dislike the object of science is Truth." In the discussion of the subject, " Was Man Created ? " our object will be not to study the many ways God might have created him, but the way he actually did create him, for all ways would be alike easy to an Omnipotent Being. Let us look at man and ask the question : What is there about him which would need an independent act of creation any more than about the " mountain of granite or the atom of sand"? The answer comes back : Besides life, man has many mental attributes. Let us direct our attention at first to the grand phenomena ojf life, and then to man's attributes. To discover the nature of life, to find out what life really is, it would be folly to commence by comparing man, the perfection of living beings, with an inorganic or inanimate substance like a brick, to discover the hidden secret ; for, as Professor Orton says :* " That only is essential to life which is common to all forms of life. Our brains, stomach, livers, hands and feet are luxuries. They are necessary to make us human, but not living beings." Instead of man, then, it will be necessary for us to take the * Comparative Zoology, p. 43. 1876. 16 PROTOPLASM. simplest being which possesses such a phenomena ; and such are the little homogeneous specks of protoplasm, constituting the Group Monera, which are entirely destitute of structure, and to which the name " Cytode " has been given. In the fresh waters in the neighborhood of Jena minute lumps of protoplasm were discovered by Haeckel, which, on being examined under the most powerful lens of a microscope, were seen to have no constant form, their outlines being in a state of perpetual change, caused by the protrusion from various parts of their surface of broad lobes and thick finger-like projections, which, after remaining visible for a time, would be withdrawn, to make their appearance again on some other part of the surface. To this little mass of protoplasm Haeckel has given the name Protanceba primitiva. These little lumps multiply by spontaneous division into two pieces, which, on becoming dependent, increase in size and acquire all the characteristics of the parent. From this illustration, it will be seen that "reproduction is a form of nutrition and a growth of the individual to a size beyond that belonging to it as an individual, so that a part is thus elevated into a (new) whole." It is to this simple state of the monera the fertilized egg of any animal is transformed the germ vesicle ; the original egg kernel disappears, and the parent kernel (cytococcus) forms itself anew ; and it is in this condition, a non-nucleated ball of proto- plasm, a true cytod, a homogeneous, structureless body, without different constituent parts, that the human child, as well as all other living beings, take their first steps in development. No matter how wonderful this may seem, the fact stares us in the face that the entire human child, as well as every animal with all their great future possibilities, are in their first stage a small ball of this complex homogeneous substance. Whether we consider " a mere infinitesimal ovoid particle which finds space and dura- tion enough to multiply into countless millions in the body of a WAS MAN CHEAT ED? 37 living fly, and then of the wealth of foliage, the luxuriance of flower and fruit which lies between this bald sketch of a plant and the gigantic pine of California, towering to the dimensions of a cathedral spire, or the Indian fig which covers acres with its profound shadow, and endures while nations and empires come and go around its vast circumference," or we look " at the other half of the world of life, picturing to ourselves the great finner whale, hugest of beasts that live or have lived, disporting his eighty or ninety feet of bone, muscle, and blubber, with easy roll, among the waves in which the stoutest ship that ever left dock-yard would founder hopelessly, and contrast him with the invisible animalcule, mere gelatinous specks, multitudes of which could in fact dance upon the point of a needle with the same ease as the angels of the schoolman could in imagination ; with these images before our minds, it would be strange if we did not ask what community of form or structure is there be- tween the fungus and the fig-tree, the animalcule and the whale ? and, a fortiori, between all four ? Notwithstanding these ap- parent difficulties, a threefold unity namely, a unity of power or faculty, a unity of form, and a unity of substantial composi- tion does pervade the whole living world." * And this unit is Protoplasm. So we see it is necessary for us to retreat to our protoplasm as a naked formless plasma, if we would find freed from all non-essential complications the agent to which has been assigned the duty of building up structure and of transforming the energy of lifeless matter into the living. Even Goethe (in 1807) almost stated this when he said : " Plants and animals, regarded in their most imperfect condition, are hardly distin- guishable. This much, however, we may say, that from a con- dition in which plant is hardly to be distinguished from animal, creatures have appeared, gradually perfecting themselves in two * Huxley.

Let us examine for a moment this substance Protoplasm, and see in what way it differs from inorganic matter, or in' what way the animate differs from the inanimate the living from the dead. Felix Dujardin, a French zoologist (1835) pointed out that the only living substance in the body of rhizopods and other in- ferior primitive animals, is identical with protoplasm. He called it sarcode. Hugo von Mohl (1846) first applied the name proto- plasm to the peculiar serus and mobile substance in the interior of vegetable cells ; and he perceived its high importance, but was very far from understanding its significance in relation to all organisms. Not, however, until Ferdinand Cohn (1850) and more fully Franz linger (1855) had established the identity of the animate and contractile protoplasm in vegetable cells and the sarcode of the lower animals, could Max Shultz in 1856-61 elab- orate the protoplasm theory of the sarcode so as to proclaim protoplasm to be the most essential and important constituent of all organic cells, and to show that the bag or husk of the cell, the cellular membrane and intercellular substance, are but second- ary parts of the cell, and are frequently wanting. In a similar manner Lionel Beale (1862) gave to protoplasm, including the cellular germ, the name of " germinal matter," and to all the other substance entering into the composition of tissue, being secondary, and produced the name of " formed matter." " Wherever there is life there is protoplasm ; wherever there is protoplasm, there, too, is life." The physical consistence of protoplasm varies with the amount of water with which it is combined, from the solid form in which we find it in the dormant state to the thin watery state in which it occurs in the leaves of valisneria. WAS MAN CREATED? 19 As to its composition, chemistry can as yet give but scanty information ; it can tell that it is composed of carbon, hydrogen, oxygen, nitrogen, sulphur, and phosphorus, and it can also tell the percentage of each element, but it cannot give more than a formula that will express it as a whole, giving no information as to the nature of the numerous albuminoid substances which com- pose it. Edward Cope, in his article on Comparative Anatomy,* gives the formula for protoplasm (as a whole), C 24 H I7 N 3 8 4- S and P, in small quantities under some circumstances. It is therefore, he says, a nitryl of cellulose : C 2 4H 20 2 -f 3NH 3 . According to Mulder the composition of albumen, one of the class of protein substances to which protoplasm belongs, is 10(C 40 H 3I N 5 0, 2 )H-S 2 P. Protoplasm is identical in both the animal and vegetable kingdom ; it behaves the same from what- ever source it may be derived towards several re-agents, as also electricity. Is it possible, then, that the protoplasm which pro- duces the mould is exactly the same composition as that which produces the human child ? The answer is YES, so far as the elements are concerned, but the proportions of carbon, hydrogen, etc., must enter into an infinite number of diverse stratifications and combination in the production of the various forms of life. Professor Frankland, speaking of protein, for instance, says it is capable of existing under probably at least a thousand isomeric forms. Protoplasm may be distinguished under the microscope from other members of the class to which it belongs, on account of the faculty it possesses of combining with certain coloring matters, as carmine and aniline ; it is colored dark-red or yellow- ish-brown by iodine and nitric acid, and it is coagulated by alco- hol and mineral acids as well as by heat. It possesses the quality of absorbing water in various quantities, which renders it some- times extremely soft and nearly liquid, and sometimes hard and * Johnson, Ency. 20 CELLS. firm like leather. Its prominent physical properties are excit- ability and contractility, which Kiihne and others have especially investigated. The motion of protoplasm in plants was first made known by Bonaventure Corti a century ago in the Charoe plants ; but this important fact was forgotten, and it had to be discovered by Treviranus in 1807. The regular motion of the protoplasm, forming a perfect current, may be seen in the hairs of the nettle, and weighty evidence exists that similar currents occur in all young vegetable cells. " If such be the case," says Huxley, " the wonderful noonday silence of a tropical forest is, after all, due only to the dullness of our hearing, and could our ears catch the murmur of these tiny maelstroms, as they whirl in innumerable myriads of living cells, which constitute each tree, we should be stunned as with a roar of a great city/' One step higher in the scale of life than the monera is the vegetable or animal cell, which arose out of the monera by the important process of segregation in their homogeneous viscid bodies, the differentiation of an inner kernel from the surrounding plasma. By this means the great progress from a simple cytod (without kernel) into a real cell (with kernel) was accomplished. Some of these cells at an early stage encased themselves by se- cr^jting a hardened membrane ; they formed the first vegetable cells, while others remaining naked developed into the first ag- gregate of animal cells. The vegetable cell has usually two con- centric coverings cell- wall and primordial utricle. In animal cells the former is wanting, the membrane representing the utricle. As a general fact, also, animal cells are smaller than vegetable cells. Their size* varies greatly, but are generally in- visible to the naked eye, ranging from -^ to -j^^nr f an ^ ncn in diameter. About four thousand of the smallest would be required to cover the dot put over the letter i in writing. The * Comparative Anatomy Orton, p. 32. WAS MAN CREATED? 21 shape of cells varies greatly ; the normal form, though, is spheroidal as in the cells of fat, but they often become* many-sided some- times flattened as in the cuticle, and sometimes elongated into a simple filament as in fibrous tissue or muscular fibre. The cell, therefore, is extremely interesting, since all animal and vegetable structure is but the multiplication of the cell as a unit, and the whole life of the plant or animal is that of the cells which compose them, and in them or by them all its vital pro- cesses are carried on. It may sound paradoxical to speak of an animal or plant being composed of millions of cells ; but beyond the momentary shock of the paradox no harm is done. The cell, then, can be regarded as the basis of our physiologi- cal idea of the elementary organism ; but in the animal as well as in the plant, neither cell- wall nor nucleus is an essential con- stituent of the cell, inasmuch as bodies which are unquestionably the equivalents of cells true morphological units may be mere masses of protoplasm, devoid alike of cell-wall or nucleus. For the whole living world, then, the primary and a mental form of life is merely an individual mass of protoplasm in which no further structure is discernible. Well, then, has protoplasm been called the " universal concomitant of every phenomena of life." Life is inseparable from this substance, but is dormant unless excited by some external stimulant, such as heat, light, electricity, food, water, and oxygen. Although we have seen that the life of the plant as well as of the animal is protoplasm, and that the protoplasm of the plant and that of the animal bear the closest resemblance, yet plants can manufacture protoplasm out of mineral compounds, whereas animals are obliged to procure it ready made, and hence in the end depend on plants. " Without plants," says Professor Orton, " animals would perish ; without animals, plants had no * Analytical Anatomy and Phys. Cutter, p. 16. 22 LIFE need to be." The food of a plant is a matter whose energy is all expended is a fallen weight. But the plant organism receives it, exposes it to the sun's rays, and in a way mysterious to us con- verts the actual energy of the sunlight into potential energy within it. It is for this reason that life has been termed " bot- tled-sunshine." The principal food of the plant consists of carbon united with / oxygen to form carbonic acid, hydrogen united with oxygen 1,0 form water, and nitrogen united with hydrogen to form ammo- nia. These elements thus united, which in themselves are per- fectly lifeless, the plant is able to convert into living protoplasm. "Plants are," says Huxley, "the accumulators of the power which animals distribute and disperse." Boussengault found long since that peas sown in pure sand, moistened with distilled water and fed by the air, obtained all the carbon necessary for their development, flowering, and fructification. Here we see a plant which not only maintains its vigor on these few substances, but grows until it has increased a millionfold or a million-mil- lionfold the quantity of protoplasm it originally possessed, and this protoplasm exhibits the phenomena of life. This and other proof led M. Dumas to say : " From the loftiest point of view, and in connection with the physics of the globe, it would be im- perative on us to say that in so far as their truly organic elements are concerned, plants and animals are the offspring of the air." Schleiden,* speaking of the haymakers of Switzerland and the Tyrol, says : " He mows his definite amount of grass every year on the Alps, inaccessible to cattle, and gives not back the smallest quantity of organic substance to the soil. Whence comes the hay, if not from the atmosphere." It has been seen, then, that plants can manufacture pro- toplasm, a faculty which animals are not possessed of ; they at * Biography of a Plant. WAS MAN CREATED? 23 best can only convert dead protoplasm into living protoplasm. Thus when vegetable or meat is cooked their protoplasm dies, but is not rendered incompetent of resuming its old functions as a matter of life. " If I," says Huxley, " should eat a piece of cooked mutton, which was once the living protoplasm of a sheep, the protoplasm, rendered dead by cooking, will be changed into living protoplasm, and thus I would transubstantiate sheep into man ; and were I to return to my own place by sea and undergo shipwreck, the crustacean might and probably would return the compliment, and demonstrate our common nature by turning my protoplasm into living lobster." As has been said before, where there are life manifestations there is protoplasm. Life is regarded by one class of thinkers as the principle or cause of organization ; and according to the other, life is the product or effect of organ- ization. We must, however, agree with Professor Orton, who says : " Life is the effect of organization, not the result of it. Animals do not live because they are organized, but are organized because they are alive." In whatever way it is looked at, life is but a forced condition. " The more advanced thinkers, then, in science to-day," says Barker, " therefore look upon the life of the living form as inseparable from its substance, and believe that the former is purely phenomenal and only a manifestation of the latter. During the existence of a special force as such, they re- tain the term only to express the sum of the phenomena of living beings. The word life must be regarded, then, as only a general- ized expression signifying the sum-total of the properties of mat- ter possessing such organization." In what manner, then, does this matter, possessing the phe- nomena of life, differ from inorganic matter, or in what manner does living matter differ from matter not living ? The forces which are at work on the one side are at work on the other. The phenomena of life are all dependent upon the working of the 24 VITAL FORCE. same physical and chemical forces as those which are active in the rest of the world. It may be convenient to use the terms "vitality" and "vital force" to denote the cause of certain groups of natural operations, as we employ the names of " elec- tricity " and " electrical force " to denote others ; but it ceases to do so, if such a name implies the absurd assumption that either " electricity " or " vitality " is an entity, playing the part of a sufficient cause of electrical or vital phenomena. A mass of living protoplasm is simply a machine of great complexity, the total result of the work of which, or its vital phenomena, depend on the one hand upon its construction, and on the other upon the energy supplied to it ; and to speak of " vitality " as anything but the names of a series of operations is as if one should talk of the "horologity" of a clock.* When hydrogen and oxygen are united by an electrical spark water is produced ; certainly there is no parity between the liquid produced and the two gases. At 32 F., oxygen and hydrogen are elastic gaseous bodies, whose particles tend to fly away from one another ; water at the same temperature is a strong though brittle solid. Such changes are called the properties of water. It is not assumed that a certain something called " acquosity " has entered into and taken possession of the oxide of hydrogen as soon as formed, and then guarded the particles in the facets of the crystal or amongst the leaflets of the hoar-frost. On the con- trary, it is hoped molecular physics will in time explain the phe- nomena. " What better philosophical status," says Huxley, f u has vitality than acquosity. If the properties of water may be properly said to result from the nature and disposition of its molecules, I can find no intelligible ground for refusing to say that the properties of protoplasm result from the nature and dis- position of its molecules." * See Huxley Invertebrate Animals, Anatomy of. f Phys.

" Seeds of wheat produced antecedent to the Pharaohs," says Bastain,* "remaining in .Egyptian catacombs through century after century display of course no vital manifestations, but never- theless retain the potentiality of growing into perfect plants whenever they may be brought into contact with suitable ex- ternal conditions. We must presume that either (1) during this long lapse of centuries the ' vital principle' of the plant has been imprisoned in the most dreary and impenetrable of dun- geons, whither no sister effluence from the general c soul of na- ture ' could affect it ; or else (2) that the germ of the future living plant is there only in the form of an inherited structure, whose molecular complexities are of such a kind that, after moisture has restored mobility to its atoms, its potential life may pass into actual life. Some of the lowest forms of animals and plants have such a tenacity to life that their vital manifestation may be kept in abeyance for five, ten, fifteen, or even twenty years. Though not living any more than the wheat, they also retain the potentiality of manifestation of life ; and for each alike, in order that this potentiality may pass into actuality, the first requisition is water with which to restore them to that possibility of molecu- lar rearrangement under the influence of incident forces, of which * Beginnings of Life, p. 104, Vol. I.

Professor Owen* says : " There are organisms (vibrieo, rotifer, macrobiotus, etc.) which we can devitalize and revitalize devive and revive many times. As the dried animalcule manifest no phenomena suggesting any idea contributing to form the com- plex one of ' life ' in my mind, I regard it to be as completely lifeless as is the drowned man, whose breath and heat have gone, and whose blood has ceased to circulate. * * * The change of work consequent on drying or drowning forthwith begins to alter relations or compositions, and in time to a degree adverse to resumption of the vital form of force, a longer period being needed for this effect in the rotifer, a shorter one in the man, still shorter it may be in the amoeba." " There is," says Dumas,f " an eternal round in which death is quickened and life appears, but in which matter merely changes its place and form." Let us now compare the inorganic world with the organic the inanimate with the animate and see if there does exist an inseparable boundary between them. The fundamental proper- ties of every natural body are matter, form, and force. One im- portant point to be noticed is, that the elements which compose all animate bodies are the very elements that help to build up the inanimate bodies. No new elements appear in the vegetable or animal world which are not to be found in the inorganic world. The difference between animate and inanimate bodies, therefore, is certainly not in the elements which form them, but in the molec- ular combination of them ; and it is to be hoped that molecular physics will, at some not far distant time, enlighten us as to the peculiar state of aggregation in which the molecules exist in living * Monthly Micros. Jour., May 1, '69, p. 294. f Chem. and Phys. Balance of Organic Nature, 1848, p. 48 (trans.). 28 UNITY OF ORGANIC AND INORGANIC NATURE. matter. As to the form, it is impossible to find any essential difference in the external form and inner structure between in- organic and organic bodies for the simple monad, which is as much a living organism as the most complex being, is nothing but a homogeneous, structureless mass of protoplasm. But just as the inorganic substance, according to well-defined laws, elab- orates its structure into a crystal of great beauty, so does the protoplasm elaborate itself into the most beautiful of all struc- tures the cell unit. Just as gold and copper crystallizes in a geometrical form, a cube bismuth and antimony in a hexagonal, iodine and sulphur in a rhombic form so we find among radio- laria, and among other protista and lower forms, that they " may be traced to a mathematical, fundamental form, and whose form in its whole, as well as in its parts, is bounded by definite geo- metrically determinable planes and angles." Now, as to the forces of the two different groups of bodies. Surely the construc- tive force of a crystal is due to the chemical composition, and to its material constitution. As the shape of the crystal and its size are influenced by surrounding circumstances, there is, there- fore, an external constructive force at work. The only difference between the growth of an organism and that of a crystal is, that in the former case, in consequence of its semi-fluid state of ag- gregation, the newly added particles penetrate into the interior of the organism (inter-susception), whereas inorganic substances receive homogeneous matter from without, only by opposition or an addition of new particles to the surface. " If we, then, desig- nate the growth and the formation of organisms as a process of life, we may with equal reason apply the same term with the developing crystal." It is for these and other reasons, demon- strating as they do the " unity of organic and inorganic nature," the essential agreement of inorganic and organic bodies in matter, form, and force, which led Tyndall* to say : " Abandon- * Inaugural Address, Aug. 19, 1874. WAS MAN CREATED? 29 ing all disguise, the confession that I feel bound to make before you is, that I prolong the vision backward across the boundary of experimental evidence, and discern in that matter which we in our ignorance, and notwithstanding our professed reverence for its Creator, have hitherto covered with opprobrium, the promise and potency of every form and quality of life." Returning now to our protoplasm, let us ask the question : Where did it come from ? or, How did it come into existence ? Though chemical synthesis has built up a number of organic substances which have been deemed the product of vitality, yet, up to the present day, the fact stands out before us that no one has ever built up one particle of living matter, however minute, from lifeless elements. The protoplasm of to-day is simply a continuation of the protoplasm of other ages, handed down to us through periods of undefinable and indeterminable time. The question of where protoplasm came from how it arose chemistry is unable to answer ; but the question is answered, probably, by spontaneous generation. Only the merest particle of living protoplasm was necessary to be formed from lifeless matter in the beginning ; for, in the eyes of any consistent evo- lutionist, any further independent formation would be sheer waste, as the hypothesis of evolution postulates the unlimited, though perhaps not, indefinite modifiability of such matter. As we have seen that there exists no absolute barrier between organic and inorganic bodies, it is not so difficult to conceive that the first particle of protoplasm may have originated, under suitable conditions, out of inorganic or lifeless matter. But the causes which have led to the origination of this particle, it may be said, we know absolutely nothing as in the formation of the crystal and the cell the ultimate causes remain in both cases concealed from us. i 30 SPONTANEOUS GENERATION. At the time in the earth's history when water, in a liquid state, made its appearance on the cooled crust of the earth, the carhon probahly existed as carbonic acid dispersed in the atmos- phere ; and from the very best of grounds, it is reasonable to as- sume that the density and electric condition of the atmosphere were quite different, as also the chemical and physical nature of the primeval ocean was quite different. In any case, therefore, even* if we do not know anything more about it, there remains the supposition, which can at least not be disputed, that at that time, under conditions quite different from those of to-day, a spontaneous generation, which is now perhaps no longer possible, may have taken place. This point is now conceded by most all of the advanced scientists of the day, arid is absolutely necessary for the completion of the hypothesis of evolution. The answer may come to this Well, suppose the first proto- plasm did originate by spontaneous generation, where did the elements or force come from which compose it ? Science has nothing to do with the coming into existence of matter or force, for she proves both to be indestructible ; when they disappear, they do so only to reappear in some other form. The coming into existence of matter and force, as also the ulti- mate cause of all phenomena, is beyond the domain of scientific inquiry. Science has only to do with the coming in of the form of matter, not the coming in of its existence. * Haeckel Ilist. of Creation. Fig. I. Pio. I.

The start, then, must be made with a homogeneous mass of protoplasm, such as the existing Protamceba primitiva of the present day, which is a structureless organism without organs, and which came into existence during the Laurentian period. It is to this simplified condition, as I have previously stated, all fertilized eggs return before they commence to develop. The first process of adaptation effected by the monera must have been the condensation of an external crust, which, as a protecting covering, shut in the softer interior from the hostile influences of the outer world. As soon as, by condensation of the homogeneous moneron, a cell-kernel arose in the interior, and a membrane arose on the surface, all the fundamental parts of the unit were then furnished. Such a unit was an organism, 34: THE COMING INTO EXISTENCE OF MAN. similar to the white corpuscle of the blood, and called amoebce. Here we have two different stages of evolution ; the protoplasma (better plasson) of the cytod undergoes differentiation, and is split up into two kinds of albuminous substances the inner cell-kernel (nucleus) and the outer cell-substance (protoplasma). Edward von Benden, in his work upon Gregarince, first clearly pointed out this fact, that we must distinguish thoroughly be- tween the plasson of cytods and the protoplasm of cells. An irrefutable proof that such single-celled primaeval animals like the amoeba really existed as the direct ancestors of man, is furnished, according to the fundamental law of biogeny, by the fact that the human egg is nothing more than a simple cell. The next step taken in advance is the division of the cell in two ; there arise from the single germinal spot two new kernel specks, and then, in like manner, out of the germinal vesicle two new cell-kernels. The same process of cell-division now repeats itself several times in succession, and the products of the division form a perfect union. This organism may be called a commu- nity of amoebce (synamoebae). From the community of amoeba morula, now arose ciliated larvae. The cells lying on the surface extended hair-like pro- cesses or fringes of hair, which, by striking against the water, kept the whole body rotating the lanceolate animals or amphi- oxus were thus first produced. Here we find from the synamcebae which crept about slowly at the bottom of the Laurentian pri- meval ocean by means of movements like those of an amoeba, that the newly-formed planaaa by the vibrating movements of the cilia, the entire multicellular body acquired a more rapid and stronger motion, and passed over from the creeping to the swimming mode of locomotion. The planaea consisted, then, of two kinds of cells inner ones like the amoebae, and external "ciliated cells." The ancestors of man, which possessed the Fig. I. Fig. II. FIG. I.

Out of the planula, then, develops an exceedingly important animal form the gastrula (that is, larva with a stomach or in- testine), which resemhles the planula, but differs essentially in the fact that it encloses a cavity which opens to the outside by a mouth. The wall of the progaster (primary stomach) consists of two layers of cells : an outer layer of smaller ciliated cells (outer skin or ectoderm), and of an inner layer of large non-cili- ated cells (inner skin or entoderm). This exceedingly important larval form, the " gastrula," makes its appearance in the onto- genesis of all tribes of animals. These gastrgeada must have existed during the older primordial period, and they must have also included the ancestors of man. A certain proof of this is furnished by the amphioxus, which, in spite of its blood relation- ship to man, still passes through the stage of the gastrula with a simple intestine and a double intestinal wall.* By motion of the cilia or fringes of the skin-layer, the gastraea swam freely about in the Laurentian ocean. The development of the gastrsea now deviated in two direc- tions one branch of gastrgeads gave up free locomotion, adhered to the bottom of the sea, and thus, by adopting an adhesive mode of life, gave rise to the proascus, the common primary form of the animal plants (zoophyta). The other branch was originated by the formation of a middle germ-layer or muscular layer, and also by the further differentiation of the internal parts into vari- ous organs ; more especially, the first formation of a nervous system, the simplest organs of sense, the simplest organs for se- cretion (kidneys), and generation (sexual organs) this branch is the prothelmis, the common primary worms (vermes). Like the turbellaria of the present day, the whole surface of their body * See Haeckel Evol. of Man. 40 THE COMING INTO EXISTENCE OF MAN. was covered with cilia, and they possessed a simple body of an oval shape, entirely without appendages. These acoelomatous worms did not as yet possess a true body cavity (cceloni) nor blood. No member of the next higher animals are in existence, neither are there any fossil remains, owing to the soft nature of their body. They are therefore called soft worms, or scoleceda. They developed out of the turbellaria of the sixth stage by form- ing a true body cavity (a coelom) and blood in their interior. The nearest still living ccelomati is probably the acorn worms (balanoglossus). The form value of this stage must, moreover, have been represented by several different intermediate stages. Out of the four different groups of the worm tribe, the four higher tribes of the animal kingdom were developed the star- fishes (echinoderma) and insects (arthropoda) on the one hand, and the molluscs (mollusca) and vertebrated animals (vertebrata) on the other. Out of certain coalomati, the most ancient skull- less vertebrata were directly developed. Among the ccelomati of the present day, the ascidians are the nearest relatives of this ex- ceedingly remarkable worm, which connect the widely differing classes of invertebrate and vertebrate animals. To these animals have been given the name of sack-worms (himatega). They originated out qf the worms of the seventh stage by the forma- tion of a dorsal nerve marrow (medulla tube), and by the forma- tion of the spinal rod (chorda dorsalis) which lies below it. It is just the position of this central spinal rod or axial skeleton, between the dorsal marrow on the dorsal side and the intestinal canal on the ventral side, which is most characteristic of all ver- tebrate animals, including man, but also of the larvse of the ascidia. We now come to the second half of the series of human an- cestors. The skull-less animal lancelet, which is still living, affords a faint idea of the members of this group (acrania). Fig. I.
