PHILADELPHIA, April 11, 1870. 
 
 On retiring from the business which I established in 1853, and h?,ve been 
 conducting at No. 924 Chestnut Street since that year, it gives me pleasure 
 to recbmmend to my friends and former patrons, my successors, and solicit 
 for them a continuance of the favors so freely bestowed upon myself. 
 
 The present firm propose dividing their business into three departments, 
 each partner giving one of those departments his special care and attention. 
 
 SAMUEL L. Fox, my former partner, will devote himself to the Mathe- 
 matical Department, which will comprise Drawing Instruments, of every 
 description, Surveying Compasses, Engineer's Transits and Levels, Surveying 
 Chains, Tape Measures, Drawing Papers, and materials of all kinds used by 
 engineers and draughtsmen. 
 
 JESSE S. CHEYNEY, formerly Principal of Friends' Select School, in this 
 city, will take the Department of Philosophy, which will comprise Magic 
 Lanterns, Oxy-Calcium and Oxy-Hydrogen Stereoscopticons, with Pictures 
 and Illustrations from all countries and upon all scientific subjects; Ther- 
 mometers, Barometers, Globes, Air Pumps, Electric Machines, Magnetic 
 Apparatus, &c., &c. 
 
 WILLIAM H. WALMSLEY, well known throughout the country as a 
 Microscopist, and also a preparer of Microscopic Specimens, will take the 
 Department of Optics, which will comprise Spectacles, Microscopes, Micro- 
 scopic Objects and Accessories, Opera Glasses, Spy Glasses, Telescopes, 
 Ophthalmoscopes, &c., &c. 
 
 The new firm will continue to issue Priced and Illustrated Catalogues as 
 follows: Part 1st. MATHEMATICS; Part 2d. OPTICS; Part 3d. MAGIC 
 LANTERNS AND STEREOPTICONS ; Part 4th. PHILOSOPHICAL INSTRUMENTS. 
 
 Care will be taken in each department of the business that the instru- 
 ments manufactured by the firm shall be well made, and accurate for the 
 purposes intended; and that all new instruments and improvements, of both 
 European and American manufacture, shall be introduced with as little delay 
 as possible.

 ACHROMATIC! OBJECT-GLASSES for SPY-GLASSES ajid TELESCOPES. 
 
 Achromatic lenses are formed by a combination of a double convex lens 
 of crown glass and a plano-concave or a concavo-convex 
 lens of flint glass. The advantages of a lens formed in this 
 manner are freedom from spherical aberration or distortion, 
 and the rays of light are not decomposed into the primary 
 1225. colors ; in other words, the light passes through the lens 
 
 and suffers no change thereby.

 SPECTACLES AND EYE-GLASSES. 
 
 HINTS AS TO THEIR SELECTION. 
 
 To select Spectacles for improving the Sight when Age is the Cause of Failure. 
 
 At the age of forty, most ladies begin to experience some difficulty in threading a 
 fine needle and reading very fine print, but gentlemen do not notice this change until 
 about the age of fifty. These ages do not hold good in all cases, but as an average 
 they can be relied upon. 
 
 Among the indications that the eyes are beginning to be impaired by age, and 
 that spectacles are required, are, the necessity of putting a book farther from the 
 eyes than a natural distance in order to read fine print distinctly ; a greater care to 
 Lave a strong light upon the reading or sewing; as, for instance, going close under 
 the window or holding the light between the eyes and the reading; on looking at a 
 near object, in a short time it becomes confused and appears to have a kind of a mist 
 before it, and the letters of a book run one into another or appear double, and after a 
 little use the eyes have an over-taxed wearied look. 
 
 In selecting Spectacles to remedy these defects of vision, it is desirable to consult an 
 experienced Optician, and with his advice and assistance to procure those best suited 
 to the condition of the eye. But in case an Optician is not readily accessible, persons 
 wanting Spectacles, instead of picking up and using any kind which may happen to be 
 at hand, regardless of the power or quality of the glasses, would do well to send to 
 us for a pair ; and if the following data is carefully given us, we will have no difficulty 
 in sending Spectacles to suit the sight: The age of the person; and state, if lady or 
 gentleman, whether spectacles have been worn; if not, give the number of inches 
 Tery small printing must be held from the eyes in order to read it distinctly in a good 
 light and send a sample of the printing: but if spectacles have been worn, send a 
 glass or piece of a glas"s from the Spectacles last worn ; state the age and sex of the 
 person; how long the last pair of Spectacles had been used, and at what number of 
 inches from the eyes with these Spectacles on very small printing must be held in 
 order to see it distinctly, and send sample of the printing. 
 
 Persons, after having used Spectacles for ten or twelve years to assist them in read- 
 ing, begin to notice a change in their sight with regard to distant objects, a little 
 want of clearness. When Spectacles are wanted to remedy this defect, if a glass from 
 a pair of Spectacles which suits for reading small printing is sent us, we can send a 
 pair of Spectacles that will correct the defect, and give clear vision for distant seeing. 
 
 To select Spectacles for Near- or Short - Sighted Persons. 
 
 Near-sighted persons, or those who do not wear glasses to assist them in reading, 
 yet are unable to see distant objects clearly, in order to have the proper 1 glasses sent 
 them, should give us the number of inches they are obliged to hold very small print- 
 ing from their eyes, and send sample of the printing. 
 
 Colored glasses blue, green, and smoke may be worn to protect the eyes from 
 intensely bright light, such as sunshine, or blazing fire; but it is not advisable to use 
 them for reading or working. The habitual using of them, where there is only a 
 moderate light, is found to have an injurious effect in rendering the eyes too sensitive. 
 
 Spectacles can be transmitted through the mail with safety to and from us. The 
 postage on a single pair is nine cents. 
 
 All orders for Spectacles will receive our prompt and careful attention. And if 
 those sent are not found to be quite right, they will be exchanged for others without 
 additional cost. In ordering Spectacles, it will only be necessary to give the catalogue 
 number of the kind wanted and the information about the sight before alluded to.

 TO DEALERS. 
 
 The prices given on pages 5 to 14, for Spectacles, Eye-Glasses, &c., are our lowest 
 retail prices. Dealers who buy Spectacles to retail again, will find our prices by the 
 dozen very low indeed, and they can always have the dozens made up of any Sights 
 they may happen to be in want of; the advantage of which is that they will never get 
 too many of any one number, while they have none of some very important numbers. 
 We have Steel Spectacles, from $1 50 per dozen to $25 per dozen. Eye-glasses, from 
 $3 50 to $20 per dozen.

 GKAPHOSCOPES, 
 
 1487. 
 
 These new, beautiful, and extremely useful instruments are growing steadily in 
 public favor, so that of late it has been almost impossible to meet the demand for 
 them. We have, however, made arrangements with two eminent foreign manufac- 
 turers, by which, in addition to our own make, we shall be enabled to keep all sizes 
 in stock, and thus fill orders promptly. Combining a perfect stereoscope with a large 
 lens for viewing single photographs, and engravings of almost any size, so constructed 
 as to give a stereoscopic appearance to them, the graphoscope realizes a want often 
 felt but never before attained, whilst its beautiful proportions and elegant finish 
 make it a handsome addition to the furniture of the library or drawing-room.

 THE MICROSCOPE. 
 
 Within the last few years, the microscope has become so firmly rooted among us, 
 that little need be said in its praise. The time has long passed away when it was 
 Tield in no higher estimation than an ingenious toy ; but it is now acknowledged that 
 no one can attain even a moderate knowledge of any physical science without a con- 
 siderable acquaintance with the microscope and the marvellous phenomena which it 
 reveals. The geologist, the chemist, the mineralogist, the anatomist, or the botanist, 
 all find the microscope a useful companion and indispensable aid in their interesting 
 and all-absorbing researches, and, with every improvement in its construction, have 
 discovered a corresponding enlargement and enlightenment of the field displayed by 
 the particular science which they cultivate. 
 
 But even to those who aspire to no scientific eminence, the microscope is more than 
 an amusing companion, revealing many of the hidden secrets of nature, and unveiling 
 endless beauties which were heretofore enveloped in the impenetrable obscurity of 
 their own minuteness. 
 
 No one who possesses even a pocket-microscope of the most limited powers can 
 fail to find amusement and instruction even though he was in the midst of the Sahara 
 itself. There is this great advantage in the microscope, that no one need feel in want 
 of objects as long as he possesses his instrument and a sufficiency of light. 
 
 Many persons who are gifted with a thorough appreciation of nature in all her 
 vivid forms are debarred by the peculiarity of their position from following out the 
 impulses of their beings, and are equally unable to range the sea-shore in search of 
 marine creatures or to traverse the fields and woods in the course of their investigations 
 into the manifold forms of life and beauty which teem in every nook and corner of the 
 .country. Some are confined to their chambers by bodily ailments, some are forced to 
 reside within the very heart of some great city, without opportunities of breathing 
 the fresh country air more than a few times in the course of the year ; and yet there 
 is not one who may not find an endless series of Common Objects for his microscope 
 within the limits of the tiniest city chamber. So richly does nature teem with beauty 
 and living marvels, that even within the closest dungeton-walls a never failing treasury 
 of science may be found by any one who knows how and where to seek for it. 
 
 There is little doubt but that if any one with an observant mind were to set him- 
 self to work determinedly merely at the study of the commonest weed or the most 
 familiar insect, he would, in the course of some years' patient labor, produce a work 
 that would be most valuable to science and enrol the name of the investigator among 
 the most honored sons of knowledge. There is not a mote that dances in the sunbeam, 
 not a particle of dust that we tread heedlessly under our feet, that does not contain 
 within its form mines of knowledge as yet unworked. For if we could only read 
 them rightly, all the records of the animated past are written in the rocks and dust of 
 the 'present. 
 
 Microscopes may be divided into two classes, simple and compound. The former 
 class may contain several lenses or glasses, but generally consists of a single lens ; 
 but the Compound Microscope must consist of at least two glasses, the one near the 
 object to be examined, and commonly called the objective, the other near the eye, and 
 called the eye piece. This class is subdivided into Monocular and Binocular instru- 
 ments, in which the object is viewed with one or both eyes, as their names imply. 
 The instruments enumerated in the following Catalogue are arranged under these 
 several heads, beginning in each with the simple and inexpensive forms, and leading 
 up to the most perfect yet devised by skill and science. We have of each kind always 
 in stock so that we can fill orders without any vexatious delays, and our customers 
 may depend upon having all mail orders attended to with as much care as though 
 they made a personal selection for themselves. 
 
34 JAMES W. QUEEN & CO., PHILADELPHIA AND NEW YORK. 
 
 A few hints as to the selection of a Microscope may not be amiss in this connection.. 
 Those who fortunately have unlimited means at their command, will find no difficulty 
 in deciding this important question, since it was long ago settled that the highest 
 grade of Binoculars are very near perfection, and leave little or nothing to be desired. 
 But to the far larger class of intending purchasers, the question of cost is an impor- 
 tant one; and for the benefit of these we beg to oft'er the following suggestions. 
 
 A common mistake with novices is to appreciate the excellence of a microscope 
 by the amount of its magnifying power. Now, in truth, no object should be viewed 
 with a power greater than sufficient to clearly show its structure, and if this can be 
 done with twenty diameters, it is folly to apply a hundred. And this is especially 
 the case with low-priced instruments, where the actual and angular apertures of the 
 objectives are small, and the corrections not so exact as in those of higher grade, ren- 
 dering them more liable to give false impressions of the object under examination. 
 And it is impossible to view an opaque object by reflected light, satisfactorily, with any 
 of the cheap forms of Compound Microscopes ; the lenses approach the object too nearly, 
 and are far too small to admit of a proper illumination of the object. For a child, 
 just learning the use of a microscope, and who will naturally desire to examine the 
 surface of any object he may pick up. or for those of riper years, who may possess or 
 contemplate purchasing a compound instrument, but who will be obliged to dissect 
 flowers, insects, &c., for minute examination, a Simple Microscope is the best form, 
 and we know of no more satisfactory ones than 1649 or 1650 of this Catalogue. 
 These are simple and compact in form and construction, easily managed by even the 
 least experienced, give clear and distinct images of the object under examination, and 
 are cheap enough to be within the reach of all. 
 
 After becoming familiar with the use of the simple microscope, and of the objects 
 suited to its powers, the young student may properly supply himself with a Compound 
 instrument wherewith to penetrate more deeply the structures of which he has until 
 now viewed merely the surface ; and in order to meet this want with a really good and 
 reliable instrument, at a low price, we some years ago designed and brought out our 
 Universal Household Microscope, No. 1660, which we believe to be the best low-priced 
 microscope ever made, and which, by reason of its intrinsic merits, has grown so 
 greatly in popular favor, that it is almost impossible for us to supply the great and 
 growing demand for it. It is so fully described elsewhere in this Catalogue, that a 
 further description here is unnecessary ; but to those whose means will not allow an 
 outlay of at least Twenty dollars for a Microscope, we would earnestly say, The 
 Household is the best you can get for less than that sum, and when provided with an 
 achromatic object-glass, No. 1660 is a better instrument than any one in the world 
 possessed fifty years ago. 
 
 If the means at the disposal of the intending purchaser are sufficient to enable him 
 to procure The Educational Microscope, No. 1669, we would single it out from among 
 the cheap instruments as the one most worthy of his attention. It is compact and 
 well built, of a graceful form, with plenty of room on the stage for any kind of an 
 object, very delicate fine adjustment for focus, a considerable range of powers, and is 
 admirably adapted to the examination of opaque objects as well as transparent ones. 
 The beautiful phenomona of Polarized Light can be obtained with it at a trifling ad- 
 ditional expense, whilst for the Young Medical Student, its compact form, moderate 
 cost, and excellent performance on all classes of Anatomical and Pathological prep- 
 arations, are cogent recommendations. 
 
 In the higher grades of moderate-priced instruments our Student's Microscope 166& 
 takes a front rank. The illustration gives a very accurate idea of the general appear- 
 ance of the stand, which is all we claim it to be. Beck's Popular Monoculars and 
 Binoculars, B 222 and B 220, are admirable instruments at very moderate cost, whilst 
 for those who are not obliged to count this very closely, the larger and most com- 
 plete stands of Beck or our own Mr. Zentmayer leave nothing to be desired. By many, 
 the small, inexpensive stands of Hartnack and Nachett are preferred to all others, and 
 they are certainly very compact and convenient. In the choice of object-glasses for 
 the better stands, we shall not attempt, to guide our readers in this place. All the 
 leading makers have their votaries, and all make admirable lenses. We have them 
 all in stock, and our customers have the advantage of comparison. It may not be 
 amiss to remark in this connection, that one member of our firm has had a long ex- 
 perience, and some little reputation as a microscopist, and that no objective is ever 
 accepted or offered for sale by us, which has not been inspected and approved by 
 him. His services are always cheerfully at the command of any customer in the 
 choice of an object-glass or stand.

 Having thus briefly given some hints as to the selection of a Microscope, it may 
 not be amiss to add a few on the preparation of objects for permanent observation. 
 We cannot of course in the limited space at our disposal do more than give a few gen- 
 eral directions; for further details the student is referred to almost any of the elab- 
 orate works on the subject, named in this Catalogue at page 80. The indispensable 
 requisites are neither numerous nor costly. Forceps, 1788 ; Scissors, 1797 and 1809; 
 Knives, 1801-1804; Needles, 1805, 1806; Turn-Table, 1814; Brass Table and Lamp, 
 1815; Glass Slips, 1821; Thin Circles, 1839; Ebonite Cells, 1833; Dropping Tubes, 
 1842; Bell Glass, 1845; Canada Balsam, 1847, 1848; the latter, contained in Capped 
 Bottles, 1863; Glycerine, 1850; Ditto Jelly, 1851; Preservative Fluid, 1852; Asphalt, 
 1854; Gold Size, 1855; White Zinc Cement, 1859; Dropping Bottles, 1869; Labels, 
 1950: with a few Camel hair pencils, a soft linen cloth, chamois-skin, and three or 
 four ounces of Liquor Potassa, will constitute a very respectable outfit, and be quite 
 sufficient for mounting all the ordinary specimens which the beginner or more 
 advanced student may desire to preserve. 
 
 All objects must be mounted in one of three ways : dry in Air, ditto in Balsam or 
 other resinous material, or moist in some preservative fluid or gelatinous medium. 
 For the first method, if the object be thin, make a circle with the Turn-table and 
 Zinc cement on the centre of a glass slip, the inner diameter of which shall be slightly 
 smaller, and the outer diameter as much larger, than the covering glass you wish 
 to use. When thoroughly hard, which will take a few hours, run a second thin coat- 
 ing of the cement on top of the first, place the object (previously thoroughly dried) 
 in the centre of the circle, put on the covering glass which will adhere to the fresh 
 cement, and finish with one or two thin coats of the same. If the object be thick, 
 proceed as above, using Asphalt instead of Zinc cement, and an Ebonite ring of 
 proper depth, in place of the covering glass at the second operation. This will give 
 you a convenient cell in which the object must be placed and secured to the glass 
 slip; a minute portion of Gold Size is the best cement for this purpose in most cases. 
 The whole should be placed under a bell glass until thoroughly dry, when a fresh 
 coating of Asphalt must be applied to the upper surface of the ring, a thin cover 
 applied and pressed down, finishing with successive thin coats of Asphalt. Do not 
 use paper cells in dry mountings; they always admit moisture, and the object is soon 
 spoiled. Always apply your cement in thin layers. Have your glass slips and covers 
 thoroughly clean. 
 
 For mounting in Balsam, the specimen must be entirely free from moisture, either 
 by drying or by being passed through Absolute Alcohol and turpentine ; in the latter 
 case it is to be transferred directly from the turpentine to the slide. If pure Balsam 
 1847 is used, a drop must be pressed from the collapsible tube upon the centre of a glass 
 slide, and the latter placed on the hot table 1815 until the Balsam spreads out, taking 
 care not to overheat it. The object must now be placed on the Balsam, a fresh drop 
 of the latter pressed on top of it, and a slightly warm cover laid upon it, in such a. 
 manner that the excess of Balsam will be forced out beyond the opposite edge of the 
 cover from that which first comes in contact with the slide. The whole must then be 
 laid in a warm place to harden, which may take some days or even weeks. Do not 
 be annoyed by the presence of air-bubbles, they will all disappear before the Balsam 
 becomes hard. If the prepared Balsam 1848 is used, place the object on the slide and 
 arrange it properly, then drop a small quantity of the Balsam upon it, and apply the 
 cover as before. A little practice will enable the young beginner to use the exact 
 quantity of Balsam necessary to make a neat mounting. If any excess exudes from the 
 edges of the covering-glass, it may be cleaned off when hard, and the slide finished with 
 a layer of Prepared Balsam 1848, applied with a Camel-Hair pencil. Never use colored 
 cements on Balsam mountings. They are certain to run in and spoil the slide. 
 
 For fluid mountings, almost the same operations as in dry mountings are neces- 
 sary. After the second coating of cement is applied, however, the cell must be filled 
 with the preservative fluid, the object (previously soaked in the same) laid in it and 
 the cover applied at one edge, so as to drive out the excess of fluid as it comes down; 
 this excess must then be soaked dry with blotting-paper or a soft towel, and a thin 
 coating of cement at once applied, to be followed by others until the slide is quite fin- 
 ished. For mounting in Glycerine Jelly the same rules will apply, the jelly being 
 first liquefied by gentle heat. 
 
 Do not be discouraged by failures at first; a little practice will make perfect. Be 
 cleanly in all your operations. Dust and moisture are the microscopist's worst foes. 
 Persevere, and success will speedily crown your efforts.

 THE CHILD'S MIOKOSCOPE, 
 
 No. 
 
 1649. The Child's Microscope, $3 50 
 
 This simple, compact and 
 perfect little instrument 
 .meets a want long felt, 
 namely, that of a really 
 good and efficient Micro- 
 scope, at an extremely low 
 price, and adapted by its 
 simplicity to the under- 
 standing of a child. The 
 magnifiers or lenses are 
 three in number, and can 
 be used separately or com- 
 bined. With the lowest 
 power, or largest single 
 lens, a large insect, such 
 as a bee or fiy, can be 
 examined without any fur- 
 ther preparation than plac- 
 ing it in the insect box 
 whh accompanies the 
 instrument. With the 
 three lenses combined, a 
 power of 700 times can be 
 obtained, which is quite 
 sufficient to show many of 
 the larger animalculae in 
 pond ox ditch water, the 
 scales from a butterfly's 
 wing, pollen grains of 
 plants, and thousands of 
 other interesting and easily 
 obtained objects requiring 
 considerable magnifying 
 power. 
 
 The illustration gives a very good general idea of the instrument, which consists 
 of a neat, flat mahogany box, as a base, into which the Microscope packs when not 
 in use ; an upright brass stem which screws into the lid of the box, and which carries 
 the stage on a sliding tube ; and at its top firmly fixed, the arm which holds the lenses. 
 The focus is adjusted by sliding the stage up or down, so that the eye is not obliged 
 to move its position as is the case with all instruments in which the focussing is 
 effected by moving the lens. The mirror for reflecting the light through transparent 
 objects is mounted on a universal joint, so as to be readily turned in any direction 
 toward the source of light. A brass box with glass bottom and top, for confining 
 insects whilst under examination, and a small pair of brass forceps for placing them 
 within it, are furnished with the Microscope, which is thus a compact and complete 
 instrument adapted equally to the comprehension of the youngest child, and to the 
 wants of the more advanced scholar or botanist; interesting the one in the minute 
 wonders of nature, and leading its infantile mind to examine into the mysteries it 
 unfolds, and aiding the other in his various studies of botany, mineralogy or ento- 
 mology. 
 
 It is much more readily managed by a novice than a Compound Microscope, and 
 has, with the three lenses combined, almost as much magnifying power as the cheap- 
 est of the latter ; whilst unlike it, " The Child's Microscope" is equally well adapted 
 to the examination of large opaque objects, such as beetles, flies or flowers. It can- 
 not be put out of order, excepting by considerable violence sufficient to break it, and 
 any ordinary child can be trusted with its use. 
 
 Rev. Mr. Wood's excellent little work, " The Common Objects of the Microscope," 
 No. 1980 of this Catalogue, is an excellent companion to the " Child's Microscope," 
 giving full direction as to its use, and the collection and preparation of objects for 
 examination.

 1650. The School Microscope, . $6 00 
 
 This instrument consists of a tubular stem about five inches high, the lower end of 
 which screws firmly into the lid of the box wherein the instrument is packed when 
 not in use. To the upper end of this stem the stage is firmly fixed ; while the lower 
 end carries a concave mirror. Within the tubular stem is a round pillar having a 
 rack cut into it, against which a pinion works that is turned by a milled head : and 
 the upper part of this pillar carries a horizontal arm which bears the lenses, so that 
 by turning the milled head, the arm may be raised or lowered, and the requisite focal 
 adjustment obtained. Three magnifiers are supplied, and by using them either sep- 
 arately or in combination, a considerable range of powers from about five to forty 
 diameters is obtained. A condensing lens for opaque objects, a pair of brass forceps, 
 and pliers, and an aquatic box for the examination of objects in water, are also sup- 
 plied. This instrument is peculiarly adapted for educational purposes, being fitted 
 in every particular for the examination of botanical specimens, small insects or parts 
 of insects, water-fleas, the larger animalcules, and other such objects as young 
 people may readily collect and examine for themselves : and those who have trained 
 themselves in the application of it to the study of nature are well prepared for the 
 advantageous use of the Compound Microscope. But it also affords to the scientific 
 inquirer all that is essential to the pursuit of such investigations as are best followed 
 out by the concurrent employment of a Simple and a Compound Microscope, the for- 
 mer being most fitted for the preparation, and the latter for the examination of many 
 kinds of objects ; and it may be easily adapted to the purposes of dissection by placing 
 it between arm rests or blocks of wood, or books piled one on another so as to give 
 a support for the hand on either side, at or near the level of the stage.

 Set of three hard rubber Slides, with openings of different kinds, to

 1651-52. (Open.) 
 
 The construction and method of using this Microscope is very simple, and will be 
 readily understood from an inspection of the engravings. It consists primarily of a 
 small wooden case, the exact size of that shown in the engravings. To one end of the 
 lid of this case is attached one of the ends of the box ; and when the lid is reversed and 
 turned upside down, it may be slid into the groove of the case, and then forms a stand 
 for the lenses and glass stage, as shown in Fig. 1651-52. (Open.) The lenses and stage 
 are supported by a steel rod, the lower end of which is hinged to the lid, so that it may , 
 be turned down and lie in a groove provided for it. When raised into the position 
 shown in the figure, it is held very securely in place by means of 'a button ; and this 
 button also serves to retain it in the groove when it is turned down. The glass stage,, 
 which is fitted into a frame of hard rubber, slides easily on the stem, so as to be 
 readily adjustable for focus, while at the same time it may be firmly fixed, by means 
 of a set-screw, at any desired height, and will then serve as a stage for dissecting 
 purposes. The frame which holds the lenses fits on to the top of the stem. A mirror 
 is fitted into the case, and is readily adjustable by means of the button shown on the 
 outside, so that light may be reflected up through the stage when the objects to be 
 examined are transparent ; and when they are to be viewed by reflected light, there 
 is a dark ground of hard rubber, which is nlso carried by the stem, and may be 
 turned under the stage, so as to cut off all transmitted light. Dissecting needles, 
 with neat handles, fit into appropriate grooves. 
 
JAMES W. QUEEN & CO., PHILADELPHIA AND NEW YORK. 41 
 
 1651-52. (Closed.) 
 
 As a dissecting microscope for botanical, entomological, and physiological work, 
 this instrument is very efficient and convenient. The glass plate is fitted into the 
 stage so as to form a cell capable of holding water, so that dissections may be carried 
 on under that liquid, or aquatic animals may be kept alive and examined at leisure. 
 The stage may also be turned, so that the flat side will be up when so desired. When 
 the lenses and stage are removed, they are readily packed in the case, as shown in Fig. 
 1651-52 (Closed) ; the stem is then turned down and held in its groove by the button; 
 the lid is drawn out of the groove, turned over, and replaced so that the vertical piece, 
 to which the button is attached, closes the open end of the box, and the whole thing 
 is packed, into a compass which readily admits of its being carried in the vest pocket. 
 
 After reading this description, probably the first question that will rise to the lips 
 of the reader is What will such a microscope do? 
 
 The lenses being well made, and provided with a proper diaphragm, which secures 
 distinctness of definition, may be used either singly or together. Some of the instru- 
 ments are provided with three lenses, and some with but two. These lenses give a 
 range of power of from five to thirty diameters, (twenty-five to nine hundred times 
 the surface,) the first being admirably adapted to the examination of minerals, textile 
 fibres and fabrics, the larger parts of flowers and insects, etc., while the latter is 
 sufficiently powerful to enable the student to dissect flowers, and examine their more 
 minute structure with great efficiency. Under good management, it will show the 
 individual corpuscles in the blood of the frog. 
 
 Its applications are as follows: In the arts it may be applied to the examination of 
 materials, to the measurement of minute spaces, and to an examination of the quality 
 of the finer kinds of work. It is the more readily applicable to these purposes from 
 the fact that the frame holding the lenses may be separated from the rest of the 
 microscope, and used by itself. By the addition of a thin piece of hard rubber, which 
 slides on the stem and is pierced with an opening of proper size, this microscope may- 
 be used as a most efficient linen prover. As a microscope for detecting counterfeit 
 money, it cannot be surpassed. 
 
 On the farm it will enable the agriculturist to examine the various noxious insects 
 and forms of fungi and blight, and thus aid him in identifying them and applying the 
 proper remedy. In the examination of minute seeds, such as timothy, clover, etc., it 
 will also prove a very valuable assistant to the farmer, enabling him to detect any 
 inferiority in the quality or any impurity or adulteration. Frequently the seeds 
 offered in market contain minute seeds of offensive weeds, many of which are so small 
 that they are not easily discovered by the naked eye.

 THE COLLEGE MICROSCOPE. 
 
 1653. 
 
 No. PRICK. 
 
 1653. College Microscope, complete with all the apparatus described below, 
 
 in fine mahogany case, ......... $40 00 
 
 The College Microscope has been designed for the use of students, likewise as a 
 seaside, travelling, or working microscope. It is both compound and simple, and has 
 a joint for inclining the instrument, and rack adjustment for focusing. It is fitted 
 in a polished mahogany case, six inches cube, and so arranged that on opening the 
 case the instrument stands on the table ready for use, and the appliances, though 
 numerous, exposed to view and readily accessible. 
 
 The objectives of the compound microscope arc achromatic, and useable separate 
 or combined, giving powers of 200, 100, and 50 diameters. The body elongates to 
 give extra power. For use as a simple microscope three simple objectives are sent, 
 useable separately or combined, giving powers with No. 1, 5 ; No. 2, 7 ; No. 3, 11 ; No. 
 1, 2, and 13; No. 1 and 3, 16; No. 1, 2, and 3, 20 diameters. 
 
 The case contains a complete set of apparatus and materials required in mounting 
 objects, including turn-table, hot-plate with spirit lamp, dissecting trough, a complete 
 set of materials and implements ordinarily required, with a stock of glass sides, cover 
 glasses, cells, and labels. The portability and compactness of this apparatus allows 
 of its being conveniently taken into the country or sea-side for use on the spot, thus 
 affording the valuable advantage of not only being able to examine but also readily 
 to mount, whilst in fresh and perfect condition, objects that are liable to become use- 
 less or seriously injured in microscopic value if the mounting has to be deferred until 
 returning home. 
 
 The Dissecting Trough is placed in the recess of the stage in place of the stage plate, 
 for the purpose of examining or dissecting an object under water, pinned down upon 
 the loaded cork or not, as required. 
 
 The Turn-table is carried upon a long spindle passed through a hole in the stage, 
 giving a very steady and free motion, and the right hand is steadily supported by the 
 microscope arm close over the turn-table whilst making varnish rings. The top of 
 the turn-table is made only the size of a glass slide and the slide is held in ita 
 place by slipping it under an india rubber band, which holds it so firmly as to prevent 
 any risk of shifting. 
 
 The Hot-plate is placed in the recess of the stage, the microscope arm being then 
 reversed in position to be clear of the stage, and the stand placed in the opposite 
 position to the one in w r hich it is used as a microscope, the spirit lamp being placed 
 in the position of the mirror. The heated slide, with ring of marine glue upon it, is 
 readily and quickly shifted from the hot-plate into the rceess in the bottom board, 
 and centred there at once by pushing it home in the recess, for centering the cell whilst 
 Btill hot enough to keep the marine glue melted.

 In Preparing Crystals of salts as polarizing objects, the microscope arm is used as 
 a retort stand for holding the watch glass for evaporating over the spirit lamp : the 
 stage plate being left in its place for warming the slide and coverglass at same time. 
 The microscope arm serves also as a stand for filtering the liquids used in mounting 
 by placing a small folded funnel of blotting paper in the ring of the arm, and setting 
 the bottle to be filled below the stage. 
 
 The following Materials for Mounting are contained in the set of bottles. The rack 
 containing them can be taken out of the case when in use, or any single bottle is ac- 
 cessible whilst remaining in the case. 
 
 Asphalte Varnish, for finishing off slides, and making varnish cells. 
 
 Gold Size, for fixing cover-glasses, &c. 
 
 Liquid Marine Glue, for making cells and cementing cells on slides. 
 
 [These are in bottles having a small camel hair brush fixed through the cork, and 
 always immersed in the liquid and ready for use without risk of the fingers getting 
 touched with the varnish. The asphalte and goldsize are kept diluted by occasional 
 addition of benzole, so as to drop freely from the brush.] 
 
 Turpentine, for cleaning off waste, slides, &c., in similar bottle, with brush fixed in 
 the cork. 
 
 [These four bottles are fitted tightly into the rack, so that the brush and cork is 
 readily taken out by one hand whilst the other hand is occupied.] 
 
 Canada Balsam diluted with benzole sufficiently for dropping freely from the 
 lipped bottle ; the cork is readily removed after being carefully loosened, and the di- 
 luted balsam is used cold, the cover-glass of an object being kept down by a spring 
 clip ; the slide being then left in a slightly warm situation, as upon a chimney piece, 
 all the air bubbles become removed in a few hours beyond the edge of the cover-glass, 
 in the course of the evaporation of the benzole, and the superfluous balsam can be 
 scraped off after a few days. 
 
 Alcohol, in lipped bottle, for cleaning off cells fixed by marine glue, and cleaning 
 objects for mounting, &c. In cleaning off marine glue, after removing it with the 
 scraper to nearly the edge of the cell, working under the microscope with light from 
 below, the cleaning is carefully finished at the edge with alcohol and the scraper. 
 
 Chloroform, for cleaning cover-glasses and slides, diluting varnish, &c., and for 
 killing and cleaning insects, &c. 
 
 Liquor Potassse, for softening and bleaching the hard coverings and antennae, &c. of 
 insects. 
 
 Goadby's Fluid, for mounting animal objects. 
 
 Glycerin and Carbolic Acid Water, for mounting vegetable objects consisting of 
 glycerin mixed with thirty times the quantity of distilled water in which carbolic 
 acid has been soaked, the whole being filtered. 
 
 Distilled Water, in larger bottle, for washing objects for mounting The contents 
 of these bottles are filtered with advantage after remaining in use for some time, to 
 remove particles of dust, &c. 
 
 Needles, Forceps, large and small, dissecting knife, scraper, stage forceps, and spring 
 clips, are contained in one drawer. 
 
 Dipping Tubes and Brushes in the opposite drawer ; kept separate to prevent any 
 risk of rusting the needles, &c. 
 
 Cover -glasses, Cells, and Labels in the smaller drawer ; and two dozen glass slides in 
 the bottom of case, with watch glasses and a small wiper for finishing the cleaning 
 of cover-glasses and slides, to be kept quite clean and free from dust and grease. 
 
 The double ring handle at top of case prevents any risk of the case opening when 
 carried by the handle if not locked.

 1660. The Universal Household Microscope, $6 00 
 
 This is the most convenient, complete and powerful Microscope ever offered for the 
 low price of $6 00. It has the important parts of a first-class instrument, is readily 
 adjusted, and well calculated not only to amuse but instruct young persons, and 
 thereby foster a taste for the study of Natural History. It has a firm tripod base of 
 cast iron, and the facility for inclining to any angle for convenience of observation ; 
 a concave mirror for concentrating the rays of light upon the object ; an adjustable 
 eye-piece or draw-tube, and two object-glasses of different powers; all packed in a 
 neat wooden box with hinges and hooks. No microscope of equal power and neatness 
 of finish has ever been offered for the same low price ; and no more instructive or 
 entertaining gift can be made to young persons. It has a magnifying power of from 
 20 to 100 diameters, or 400 to 10 5 000 times the area. 
 
 MAGNIFYING POWERS. 
 
 Objective No. 1 is the lowest power, and, with the tube closed, gives a power of 20 
 diameters or 400 times the area ; with the extension tube drawn out to three inches, 
 the power is 40 diameters or 1600 times the area. 
 
 Objective No. 2, with the tube closed, gJves a power of 50 diameters or 2500 times 
 the area ; with the extension tube drawn out to three inches, the power is 100 dia- 
 meters or 10,000 times the area. 
 
 The magnifying power , as understood by microscopists, is in diameters. A popular way 
 is to give the area or super/ices ; and, as th* object is magnified equally in all directions, this 
 power is obtained by squaring the diameter. 
 
 We have a great variety of objects, neatly prepared and mounted on glass papered 
 slides, with name on each, well calculated for the Household Microscope. We sell 
 them at the low prices of $2 00 per dozen, or 20 cents for any single slide. 
 
 A suitable and interesting Book on the Microscope, with directions for collecting 
 and preparing the objects, can be had with it. Price 50 cents, with 400 colored 
 illustrations.

 QUEEN'S POPULAR MICROSCOPE, 
 
 1664 J. Queen's Popular Microscope. This Stand, as its name imports, has 
 been designed and constructed by us expressly for popular use, and 
 places within the reach of all a full-sized instrument of first-class 
 workmanship, capable of carrying objectives of any make, and all 
 the accessories of Queen's Student's Microscope, so that in addition 
 to the ordinary objects usually viewed in the microscope, all the 
 beautiful phenomena of Polarized Light, Dark Field Illumination, 
 &c., &c., are exhibited by it in the most satisfactory manner. 
 
 The Stand is 14 inches high, the base being of iron, handsomely 
 japanned in a light bronze color, and very firm and steady. Body, 
 stage, and movements all of highly finished brass. The coarse 
 adjustment of focus is made by a friction pinion and milled heads, 
 
 , the fine adjustment by a lever working so delicately that the 
 
 highest powers may be used with the greatest accuracy. There is 
 sufficient length of motion in the body to admit of using a 2-inch 
 objective. The stage is very large and roomy, with a thin super- 
 stage or object-carrier, having a very delicate movement in every 
 direction of more than one inch. The Mirror is mounted in the 
 most approved manner, admitting the greatest obliquity of illumi- 
 nation, and the body is fitted with the Society Screw, allowing 
 objectives of any make to be used. Beneath the stage is a revolving 
 diaphragm of various sized openings, carried in a tube, which also 
 holds the Polarizing Prism or other accessories when in use. 
 
 The price of this really excellent microscope has been fixed 
 very low, which must insure a large sale. With One Eye-Piece, 
 and No. 8 French Object Glass, giving powers from about 60 to 
 300 diameters; Condensing Lens on separate stand for opaque 
 objects; Needles and Forceps; and packed in a neat oiled walnut 
 case, with good brass handle and lock, the cost is only

 1669. THE EDUCATIONAL MICROSCOPE, . . $37 60 
 
 This is believed to be the best low priced Microscope ever offered to the public, and 
 it may safely be relied upon as capable of performing all the work required by the 
 young student in any department of Microscopical science. It is not of course ex- 
 pected that it will bear comparison with Microscopes of many times its cost, but it is 
 infinitely superior to the best Microscope ever constructed on the old (non-achroma- 
 tic) plan. The simplicity of its construction, and the facility with which all those 
 adjustments may be made that are required for the purposes it is intended to fulfill, 
 constitute with its low price, a great recommendation to those who value a Microscope 
 rather as a means of interesting recreation for themselves, or of cultivating a taste for 
 the study of nature, and a habit of correct observation in the young, than as an in- 
 strument of scientific research. 
 
 The stand is entirely of brass, of handsome proportions, and well finished ; th? 
 compound body is mounted upon a double axis joint, allowing the instrument to be 
 inclined at any angle convenient to the observer, with quick rack adjustment and fine 
 screw adjustment for focus, sliding object-holder, plane and concave mirrors, wheel 
 of diaphragms, and the following accessories :

 CKOUCH'S BINOCULAB MICKOSCOPE, 
 
 1710. 
 
 This is one of the best instruments of its class in use, and we strongly recommend 
 it to such as desire to possess a Binocular at once cheap, good, and portable. Its 
 general arrangement is shown in the illustration above, the double body being sup- 
 ported on a "limb" on the Lister model. The adjustment of the eye-pieces for the 
 distance of the eyes is made by a transverse bar which is attached to one of them, 
 and which works through a slot-piece fixed to the other; so that if, by the applica- 
 tion of the finger and thumb to the projecting pin, the bar with the attached eye- 
 piece be raised or lowered, the other eye-piece also is moved accordingly. The 
 stage is circular in form, and consists of a plate of polished black glass, over which 
 the object-holder slides in every direction with the greatest facility, and is so ar- 
 ranged as to afford entire concentric rotation in the optic axis ; an indispensable 
 feature in a good Binocular instrument. 
 
JAMES W. QUEEN A CO., PHILADELPHIA AND NEW YORK. 55 
 
 This Microscope in its "Binocular" form, the first introduced to the scientific 
 public at a reasonable cost, has steadily increased in reputation, and has now 
 attained the highest position of any microscope of its class. Its thorough excel- 
 lence of performance, stability in any position (in this respect being unrivalled), 
 simplicity of construction, and consequent non-liability to derangement, render it 
 by far the most perfect working microscope extant. It has now for many years 
 been favored with the approval of Dr. Carpenter, as his own working microscope, 
 and was the instrument selected for use by him on the important expedition of 
 H. M. S. "Porcupine."

 on the following page. These are not the ordinary commercial lenses usually sold 
 at low prices, and most of which are mere toys, but are good, well-corrected glasses, 
 made especially for us by one of the most eminent Opticians of Paris, and we guar- 
 antee their performance to be satisfactory. If cheaper lenses are wanted, we have 
 those usually sold, in stock, at prices about 25 per cent, less than the following list.

 1867. Fiddian's Microscope Illuminator, nickel plated, 
 
 This very convenient and useful Lamp has been designed to combine the qualities 
 of other Microscope Lamps, together with greater portability, the whole fitting into 
 a brass tubular box, the exterior of which is covered with morocco leather, the lid 
 forming the stand of the Lamp. The metallic chimney being telescopic, occupies a 
 very small compass ; the condenser fits into the cell in front. The reservoir is of 
 brass, and will contain sufficient petroleum for six hours' consumption. The entire 
 Lamp fitting into the case from the top, escape of the oil is prevented. 
 
 In trimming the Lamp care should be taken that the wick is perfectly dry, and 
 the petroleum of good quality: also that none of the oil gets upon the metallic chim- 
 ney or reservoir, or a bad smell will be given off until the oil is burnt away. 
 
 In using the Lamp it will be found convenient to slightly incline it, so as to bring 
 the broad surface of the flame more parallel with the surface of the mirror of the 
 microscope. 
 
 When it is necessary to re-line the chimney, screw off the sliding portion, wash 
 out the old lining, and re-coat it with superfine Plaster of Paris. When dry it will 
 be found ready for use a few minutes will be found sufficient to do this.

 Microscopists will find this new form of COLLECTING BOTTLE an indispensable com- 
 panion in their Pond-hunting Excursions, for collecting and retaining the various 
 minute objects that may be obtained in water by the dipping bottle. It consists of a 
 bottle with a movable brass cap, in which is fastened two small tubes with screw 
 tops. One of these (A) projects a little higher than the other ; in which is fixed the 
 funnel (C) when in use. The other tube (B) has a trumpet-shaped form, across the 
 mouth of which a piece of fine muslin is stretched; the loose funnel shown is placed 
 in the outer tube, and the water containing the various organisms which it is wished 
 
JAMES W. QUEEN & CO., PHILADELPHIA AND NEW YORK. 
 
 to retain is poured into it. As soon as the bottle is full the water rises through the 
 porous material placed across the lower end of this inner tube, and flows over re- 
 taining behind and in the bottle the various diatoms, volvox, desmids, entomostraca, <^c., 
 which may have been floating therein. Any quantity of water may be deprived of 
 the minute objects floating in it, without the troublesome, imperfect and destructive 
 process of first filtering through a piece of muslin or flannel, and then reversing the 
 filtering material in the mouth of the bottle, to detach the deposit. 
 For collecting larger objects, the cap of the bottle can be removed.

 HOLMAN'S LIFE AND CURRENT SLIDES. 
 
 These very useful and ingenious accessories to the Microscope are attracting great 
 attention among scientific men everywhere, and have received the strongest commen- 
 dations from Medical and other Scientific Journals at home and abroad. By an 
 arrangement with the inventor we are enabled to supply them to our customers of the 
 most perfect quality, each one having passed through Mr. Holman's hands before 
 being delivered, to us.

 HOLMAN'S LIFE SLIDE, with Cover, in a neat Box, . . . . $1 50 
 THE LIFE SLIDE consists of a plate of thick glass 3x1 inch, with a deep oval cavity 
 ground in its centre, to contain the mass of material under observation. Around the 
 margin of this oval cavity is a polished bevel, and from the bevel extends a small cut, 
 the object of which is to afford an abundance of fresh air to the living things within. 
 It is found upon enclosing the animalculae, etc., that they will invariably seek the 
 edge of the pool in which they are confined, and the bevelled edge permits the observer 
 to take advantage of this disposition ; for when beneath it, the objects are within the 
 range of the highest powers. 
 
 The Life Slide is constructed to retain the greatest quantity of material under the 
 smallest cover glass, and is designed to be used with the highest powers of the Mi- 
 croscope for studying the Bacteria, Vibriones, and other low forms of life. For 
 studying the circulation of the blood in the tail of the Tadpole, it is the most perfect 
 contrivance imaginable. The deep oval cavity will contain the body of a small Tad- 
 pole, whilst the tail lies extended in the bevelled portion, and may be examined with 
 the highest powers. Another very important feature in the device is the fact that a, 
 preparation may be kept with it for days or weeks together without losing vitality, 
 owing to the simple arrangement for supplying fresh, air.

 $1 50 
 
 The Current Slide consists of slip of plate glass 3x1 inch, in which two oval concave 
 cells are ground, there being a space of ^ in. left between the cells. These cells, 
 which are about in.- in diameter and as deep as the glass will permit say -fa in. 
 deep are united by a very shallow channel somewhat below the centre of the two 
 cells, so that with cells placed -fa in. apart, the channel is about -fa in. long. Both 
 the cells and channel are polished. If a few drops of blood be placed in these cells, 
 and a cover of thin glass be pressed down, some of the blood, finding its way between 
 the surfaces in contact, will dry, and act as a cement to hold the fluid blood in the 
 cells in place. The quantity of blood being insufficient to fill the cells, a considerable 
 amount of air becomes imprisoned with the blood, and the expansion of the air in 
 either cell will drive the blood through the channel into the adjacent cell, and in the 
 shallow channel it is presented under the most favorable condition for examination. 
 By holding the top of the finger near one or the other cell, the heat is enough to cause 
 
JAMES W. QUEEN & CO., PHILADELPHIA AND NEW YORK. 6T 
 
 the expansion and a consequent more or less rapid flow of the fluid through the chan- 
 nel. This flow may be arrested, or continued and reversed at will, by change of 
 position of the finger, so that any particles floating in the liquid can pass in succession 
 across the field, but can be arrested and examined with ease at will. 
 
 So sensitive is the apparatus, that even with the highest powers, a corpuscle, 
 granule, or cell in the field of view, may be leisurely turned over and over in any 
 desired position, thus affording an unequalled means of observation and study to the 
 microscopist ; and while the eye is examining at leisure the behavior of the objects 
 beneath it, the mind is charmed with the simplicity of the means by which their 
 motions are controlled. 
 
 Blood or other fluid inclosed in the cetls remains in good condition for examination 
 for several days, and changes undergoing in the fluid can be examined.

 1884. HOLMAN'S SYPHON SLIDE, complete, with Flexible Tubes and Glass 
 
 Cover, but without Bottles, . . . . . . $4 50 
 
 This is a modification of the "LIFE" and "CURRENT" slides, whereby living objects 
 of suitable size and habits can be retained under observation uninterruptedly for 
 days or even weeks. A current of water, or other fluid, is made to flow continuously 
 through the chamber containing the object, so that the processes of respiration, cir- 
 culation, digestion and nutrition, the phenomena of inflammation, and the effects of 
 some classes of poisons, may be studied at leisure and under perfectly natural or 
 entirely controllable conditions. The habits of life of small aquatic animals are 
 similarly brought within reach of our observations. For use with the Magic Lantern, 
 in projecting the images of living objects upon the screen, this apparatus is absolutely 
 perfect the flow of fresh water through the chamber being so constant that its 
 inmates are entirely free from inconvenience during the most protracted exhibition. 
 
 The following description of the SYPHON SLIDE will render its construction and use 
 quite clear. In a slip of thick plate glass, a chamber is excavated similar to that in 
 the LIFE SLIDE. In each end of this chamber are fine perforations, too small to 
 permit the escape of the animal under view, but sufficient to maintain a flow of water. 
 These openings merge into tubular mouths, to each of which is attached a tightly- 
 fitting elastic tube : one of these communicates with the reservoir of water, whilst 
 the other acts as an escape conduit. The position of the slide, when in use, must be 
 slightly above the level of the reservoir, while the escape-tube must rest below the 
 same, thus insuring a veritable syphon action in the apparatus ; a constant flow of 
 water being secured in connection with the required atmospheric pressure for the 
 retention of the cover on the slide. It is not necessary to have bottles specially fitted 
 for use with this apparatus ; any vessel capable of holding water will answer, it being 
 only necessary to insert the end of one tube in the reservoir, and by gently sucking 
 at the end of the other establish a flow of the water, which will continue so long as 
 the reservoir contains any.

 Directions for Use. To fill the lamp, take out the holder A, invert it and pour in 
 the oil till it reaches the valve ; then pull up the valve by means of the wire B ; in- 
 vert it, holding it above the holder X, so that any oil which may escape drops into this 
 holder ; replace it in the holder X. 
 
 This lamp gives a very superior and steady light, and with ordinary care will emit 
 neither smell nor smoke. One-twelfth or one-eighth of a heavier oil, Sperm, Lard 
 or Olive, mixed with Kerosene, makes the best and safest oil. 
 
 Testimonials have been given by highest authority, as to its safety against explo- 
 sions. 
 
 The wick should be trimmed regularly. If a crust has formed, do not disturb it, 
 but only remove any little point or unevenness that may occur ; do not use the scis- 
 sors unless the wick, through uneven draft, should have coaled or charred unevenly. 
 By this method you will have an even flame, and the wick will last much longer than 
 when cut frequently. If your lamp should make a humming noise, which is caused 
 by the shank of the chimney being of the wrong length, raise the chimney slightly, 
 or change it for one with a longer shank. 
 
 Use kerosene or spirits in place of water for cleaning chimneys. The brass part 
 of the lamp may be cleaned with Vienna lime and kerosene, and polished with rouge.

 INTRODUCTORY REMARKS AND EXPLANATIONS, 
 
 Although this Catalogue is intended as a guide in the selection and purchase of 
 objects, yet it is obvious that no such list can be strictly correct for any considerable 
 time, since new objects are being added continually, and the vacancies that occur 
 cannot always be filled instantly. It must therefore be understood that these object* 
 can be supplied on demand with probability rather than certainty ; hence, it is advis- 
 able when ordering to name a few more than the number actually required. In this- 
 Catalogue about 2,000 objects are comprised ; of these it may be calculated that more 
 than one-half will be found in stock. Any object not specially named will be pro- 
 cured, if possible, when ordered, and orders are solicited for any object desired, even 
 if not named in the Catalogue, as it is our aim to keep and supply the fullest assort- 
 ment of Microscopic Objects to be found in this country. The alphabetical arrange- 
 ment has been preserved throughout, as the easiest guide to any particular specimen. 
 
 The prices marked on the top of each page have a general signification only to the 
 objects on that page, and refer to the majority that follow. Some of the exceptions 
 are marked ; but the prices of many are liable to fluctuation from scarcity or abund- 
 ance, although it is the intention to adhere as closely as possible to the general list of 
 prices herein named. 
 
 In the selection of these specimens, the aim has not been so much to reduce the pries 
 as it has to improve the quality, by supplying every object as clean and perfect as its 
 nature will admit. The predominant wish has not been to introduce as many objects 
 as possible in each department, but rather to rest satisfied with such as are the most 
 beautiful as natural objects, or of their kind the best illustration of special structure 
 or function, and hence, of the highest interest both to the student in science and the 
 popular observer also. 
 
JAMES W. QUEEN & CO., PHILADELPHIA AND NEW YORK. 
 
 Any person confidentially known, or giving reference to those who are, if he desires 
 to purchase a reasonable number of objects, can have an assortment sent for exami- 
 nation and approval, the express charge both ways being at his expense, the objects 
 to be returned within one tveek, and the risk of damage or loss in transit borne by the 
 purchaser. Such specimens are sent securely packed in rack boxes, affording facili- 
 ties for inspection, as well as for packing and returning those not chosen. 
 
 In this Catalogue will be found many objects admirably suited to educational and 
 instructional use for the elucidation of general principles, as well as of special appli- 
 cation and adaptation. In Entomology, the various parts of Insects; in Botany, the 
 Elementary Tissues of Plants ; in Anatomy and Physiology, the organic structure in 
 Man and the lower animals ; the Microscope thereby affords the parent and tutor a 
 pleasing aid to the communication of useful and truthful knowledge. It would be a 
 laborious task to specify those objects that have especial interest either from their 
 novelty, beauty or scarcity ; but there are many that may repay careful notice among 
 the Whole Insects, the Transparent Injections and Polariscope Objects, and the Mis- 
 cellaneous Vegetable Preparations. 
 
 Special attention is called to our cheap aeries of Educational Objects Nos. 1955 
 and 1956, which fill a long existing want, by supplying well prepared and properly 
 named objects to students and others at a low price. Their excellence is apparent 
 on inspection.

 MOLLEE'S DIATOMAOEEN TYPEN PLATTE, 
 
 1951. Moller's Diatomaceen Typen Platte, No. 1, is a slide of the usual size three 
 inches by one inch comprising about 500 Diatoms (correctly 392 distinct species 
 and varieties), being acknowledged types of Seventeen Genera of the Order Diato- 
 maccce. The shells are arranged in four quadrangles, each formed of six lines, and 
 each line containing about sixteen species, presenting a figure of the following form:

 The Diatoms are prepared in the best manner, mounted in Balsam, absolutely pure 
 and clean, while the integrity of each and the symmetry of the whole may be said to 
 be as perfect as possible. 
 
 Easy reference to each member is afforded by an accompanying Printed Catalogue, 
 by which the name of any individual Diatom on the slide may be learned; or any 
 name in the Catalogue as easily identified with its corresponding shell on the slide. 
 
 The classification is that of Herrn A. Grunow, of Berndorf, near Wien. 
 
 To the name of each Diatom is appended its nature, whether fossil or recent. Its 
 origin, whether marine or from brackish or fresh water. Its geographical locality, 
 with the name of the naturalist who assigned its nomenclature. 
 
 On the whole it is a marvellous production of human skill and unceasing persever- 
 ance, a wondrous example of accurate manipulation and delicacy of touch, exciting 
 the admiration of all who see it. To the Naturalist and Student it forms a Cyclopae- 
 dia of reference, which may be long and repeatedly studied, with untiring interest 
 and returning freshness. It is worthy of a place in the cabinet of every advanced 
 Microscopist. 
 
 The price, in morocco case, with bound Catalogue, is .... $40 00 
 
 1952. Moller's Diatomaceen Typen Platte, No. 2, is a smaller collection of 
 
 One Hundred Diatoms by the same artist, arranged on the same 
 plan in one quadrangle, accompanied by a printed Catalogue, and 
 quite equal in quality to the larger collection. The price of this is 16 00 
 
 1953. Moller's Diatomaceen Probe Platte is a collection of 20 Diatoms, by 
 
 the same artist, arranged in a single line, on a slide of the usual size 
 3x1 inch and graduated, according to their value as test objects.

 NOBERT'S BANDS OF TEST LINES, 
 
 We receive direct from M. Nobert, of Pomerania, his exquisitely fine Bands of 
 Lines, ruled on glass, as described in a communication to the American Naturalist, 
 April, 1868, reprinted in the Quarterly Journal of Microscopical Science, October, 1868, 
 p. 131, and referred to in Dr. Carpenter's Microscope and its Revelations, fourth edi- 
 tion, London, 1868, p. 180.* 
 
 The latest and finest of M. Nobert's productions consist of a series of Bands of 
 Lines from No. 1 to 19, the distance of the divisions in the first being about the 
 11,000th part of an English inch, and those of the latter the 112,000th part of the 
 same. They are mounted in two ways. In the first, price $60, the lines are ruled 
 on a slip of plate glass, protected by a cover of thin microscopic glass. The more 
 expensive form, price $90, has its lines ruled on a plate of microscopic glass, thick- 
 ness -003, and covered by one of corresponding size and thickness. These are 
 mounted on a slip of brass 3 inches by 1 inch, so that the lines, being reversible, 
 may be examined on either side under an achromatic objective of one-fiftieth of an 
 inch focus. This form has the advantage of admitting the close approach of any 
 achromatic condenser to the Lines, and at the same time facilitates their illumina- 
 tion by the most oblique pencils of rays. The Lines themselves are essentially the 
 same at $60 and $90.

 CHEAP EDUCATIONAL OBJECTS. 
 
 The uses and pleasure of a Microscope are greatly increased by having at hand a 
 collection of well-mounted specimens, since, however desirable it may be to prepare 
 one's own objects, or to study the same without any special preparation, it follows 
 that there are thousands of highly interesting and instructive objects which cannot 
 be obtained in the raw state (if we may so express it) by every one, or at a moment's 
 notice, when needed. The unavoidably high price of the finest preparations has 
 long been a serious hindrance to many who would gladly possess a comprehensive 
 collection, but find the cost a serious tax upon their pockets, whilst the so-called 
 cheap objects imported from Europe are of such an utterly worthless character as to 
 deter them from purchasing, even at the low prices asked for the same. 
 
 In order to meet this want, we some years since introduced our "Cheap Educa- 
 tional" series of objects, which at once met with universal favor, and the demand 
 for which has steadily grown until it taxes all our ability to meet the same. These 
 objects are prepared and mounted under the immediate supervision of our Mr. 
 Walmsley, are all clean and excellent specimens of their various classes, embrace an 
 endless variety of animal, vegetable, and insect subjects, diatoms, minerals, metals, 
 etc., and are guaranteed to be correctly named, a matter of great importance for 
 educational purposes. The Microscope having become an indispensable adjunct to 
 every well-regulated school, it follows that the specimens shown the scholar should 
 be good and reliable ones. 
 
 We divide these objects into two series or classes. The first, or School Series, are 
 mounted on slides measuring 2f by f inches, and are best suited to the smaller and 
 cheaper kinds of Microscopes, which have not sufficient stage room to allow of the 
 larger slides being conveniently used. The second, or Student's Series, are mounted 
 on slides measuring 3x1 inches, the same size as the most expensive objects. This 
 series is more extended in variety than the former, containing many large insect, 
 vegetable, polariscope, and opaque specimens which cannot be mounted on the 
 smaller slides. Both series are covered with handsome gilt labels, specimens of 
 which may be found on page 70 of this Catalogue, over Nos. 1948 and 1949. The 
 quality of the specimens is the same in both series, which are catalogued as follows :

 rack boxes, containing one dozen specimens, . . . . $2 00 
 
 Single slide, 20 
 
 * "The mathematical certainty with which the distance of these lines may be ascertained, and the reg- 
 ular gradation of the series they present, gives to M. Nobert's Test Plate a very high value for the deter- 
 mination of the relative merits of achromatic objectives, of that class at least in which angular aperture 
 and definition are of the first importance." Carpenter on i?te Microscope, fourth edition.

 We take pleasure in announcing that we have recently completed arrangements 
 with Dr. J. W. S. Arnold, of New York, by which we shall be continually supplied 
 with his beautiful preparations of Human Anatomy, including opaque and transpar- 
 ent injections, preparations of the eye, brain and spinal cord, and an infinite variety 
 of Pathological preparations. Our Mr. Walmsley will also continue to furnish his 
 illustrations of Animal, Vegetable, and Insect Anatomy. His preparations were 
 awarded the highest premium (Medal and Diploma), at the recent Fair of the American 
 Institute, New York, and are at least equal to any imported. 
 
 Mr. Arthur C. Cole, of Liverpool, England, will also supply us with his exquisite 
 slides of arranged diatomaceae, polycistina, and foraminifera, which are quite unique 
 in their general arrangement and finish.

NOTICE. 
 
 Having completed arrangements with Messrs. R. & J. BECK, whereby Tre 
 are constituted special agents for the sale of all articles of their manufacture in 
 the United States, it affords us pleasure to announce to our friends and the 
 public generally, that we have now in stock, and shall hereafter keep on hand 
 a full line of their goods, the prices of which are the same as those in London, 
 United States duties and freight charges only being added. These goods are 
 specially selected for our sales, and are guarantied to be only the first qualities 
 of their respective grades. 
 
 Having them always in stock, we are prepared to fill orders promptly, thus 
 avoiding the vexatious delays our microscopists have so long been obliged to 
 submit to in obtaining instruments and accessories. If it is desired, however, 
 to import any article specially, we can do so at the shortest notice ; in tljis case 
 a pre-payment of one-half the amount of the order will be required. 
 
 Under the New Tariff Act, Institutions of Learning, are entitled to import 
 scientific instruments free of duty. We are prepared to receive and execute 
 such orders very promptly. 
 
 It is unnecessary for us to say aught in praise of the instruments manufac- 
 tured by this eminent firm, whose fame is world wide. We would, however, 
 call especial attention to their New -^ Immersion Object-Glass, which, in every 
 particular, is believed to be superior to any of similar power heretofore produced, 
 whilst its price is but little more than half those of other makers.

FIRST-CLASS MICROSCOPES. 
 
 A STAND, of similar construction to those in this class, was shown by R. & J. B. at 
 the Great Exhibition of 1851, and is thus mentioned by the Jury : 
 
 "The Stand is excellent in principle; the body, stage, and appliances beneath are 
 all carried on one stout bar, on the recommendation of Mr. G. Jackson, by means of 
 which the centring of the achromatic illumination is rendered easy and certain ; and 
 on any tremor being communicated to the instrument, it is equally distributed over 
 the whole of the working parts."

 GENERAL REMARKS. 
 
 The difference in the price of " First-class Microscopes" as numbered in this Cata- 
 logue, is dependent upon the number of Object- Glasses and the amount of Apparatus 
 supplied, the quality being the same throughout. 
 
 The Eye-pieces should be frequently wiped with a clean cambric handkerchief, or a 
 piece of soft wash leather. The Object- Glasses should never be touched, except by 
 the makers. 
 
 Full instructions, as to the best mode of using all the foregoing instruments, are 
 given in Richard Beck's Treatise on the Construction, Proper Use and Capabilities of 
 R. & J. Beck's Achromatic Microscopes. Royal 8vo, with 27 plates. Price, $8. 75.
