photographs of some of the external 
 
 Letter to the Surgeon General of the Army accompanying seven 
 appearances of the Mosquito. 
 
 Army Medical Museum, 
 
 January 5, 1872. 
 
 BRIGADIER GENERAL J. Iv. BARNES, 
 
 Surgeon General. U. S. Army. 
 
 General: During the recent Christmas holidays I employed a few mornings in making photographs 
 of the microscopical appearances of certain insect preparations. It was my desire to comply with the wish 
 you had not long before expressed that I would put into your hands a few representations of familiar 
 objects which might serve to illustrate, to intelligent persons unacquainted with the technical details of 
 histological research, the powers of the microscope and the possibility of fair photographical illustrations 
 of microscopical subjects. 
 
 The series of negatives produced represent: 1. The external appearance of the Mosquito. 2. Certain 
 Parasites. 3. The Proboscides of various Flies. 4 Some miscellaneous views of insects and parts of insects. 
 
 In submitting these pictures for your favorable consideration, 1 beg you to understand that I do not 
 offer them as scientific studies of the objects represented The microscopical work conducted under my 
 supervision at the Museum is necessarily confined to the investigation of disease, and so much of uorrnal 
 histology as is indispensable to the right comprehension of morbid processes. The present effort is there- 
 fore quite out of my usual line of work and the result must be judged with a full understanding of that 
 fact. To make a sincere scientific investigation of the anatomy of the Mosquito alone, to prepare the 
 necessary specimens and to reproduce them photographically, would be at least an undisturbed year’s hard 
 work for the most zealous microseopist. Such an investigator, had he fortunately the time and means at 
 his disposal, w-ould so modify his specimens by the use of proper bleaching and other reagents, as to render 
 it possible to photograph the least detail in the most satisfactory manner; whereas I, compelled from the 
 circumstances of the case to make use of such ready made specimens as I could procure in the market at 
 a nominal cost, could only hope in the brief time at my disposal to indicate what might have been done in 
 the same direction under more favorable circumstances. 
 
 With these preliminary remarks I proceed to a brief description of the series representing the external 
 appearances of the Mosquito. 
 
 These photographs represent views of different portions of a male Mosquito prepared by Mr. W. II. 
 Walmsley of Philadelphia. Pa. 
 
 The Mosquito of the United States is closely allied to the Gnat of Europe which has been so often 
 the subject of microscopical writers 
 
 The first photograph (Negative No. 493, new series) gives a view of the whole insect magnified eleven 
 diameters by Beck’s 4 inch objective. Even with this low power the plumose antennae, the complex 
 stinging and sucking apparatus, the six legs, the abdominal segments, and the terminal hooks of the tail 
 are plainly indicated. The plumose antennre and the hooks of the tail arc peculiar to the male insect, the 
 same parts being quite different in the female. 
 
 The second photograph (Negative No. 495, uew series) represents the head of the Mosquito magnified 
 90 diameters by Beck’s 2-3rds. 1 A portion of the hexagonal facets of the compound eyes are indicated, and 
 portions of the branching auteunse and other appendages of the head with their hairs and scales are shown.

Litter to the Suryeon General of the Army \ accompany ivy ten photoyraphs of certain parasites. 
 
 Army Medical Museum, 
 
 January 10, 1872. 
 
 BRIG ADIEU GENERAL J. K. BARNES, 
 
 Surgeon General, I'. S. Army. 
 
 General: In my letter accompanying certain photographs of the Mosquito, I explained the circum- 
 stances under which these representations of subjects so foreign to my ordinary line of work, were produced. 
 Ou the present occasion, therefore, I confine myself to a brief description of the photographs herewith 
 transmitted. 
 
 No. 1. Bed-bug ( Cimv.e lect alarms') magnified 30 diameters. Negative No. 455, new series. This 
 is a hemipterous insect, in which, however, the wings are wanting. The photograph exhibits the numerous 
 bristles or hairs with which all portions of the creature arc beset; the six legs with their terminal hooks; 
 the small, somewhat quadrate head, deeply sunk in the prothorax ; on eaeh side of the head the four- 
 jointed antcume or feelers, (the last joint of the left antenna is broken off); and finally between the 
 antennae the jointed beak with which the bug makes its attack upon our flesh. 
 
 No. 2. Head-louse ( Pctlinilus capitis ) magnified 50 diameters. Negative No. 452, new' series. The 
 louse, like the bed-bug, is a wingless hemipterous insect. The specimen photographed is a male. The 
 picture shows the integument of the insect to be every where beset with short delicate bristles. Each of the 
 six legs terminates in a conspicuous claw, admirably formed for grasping the hairs among which it lives. 
 Hie head bears two five-jointed antennae between which the mouth-parts terminate in a beak-like sucker. 
 1 his latter, however, is fleshy and retractile and in the specimen represented, being drawn within the 
 head, is not seen On the margins of the abdominal segments are the circular orifices of the tracheae or 
 Ineathing tubes, which in insects convey air to all portions of the body and act instead of luugs. Some 
 parts of the abdomen are so transparent that the larger of these tracheae are shown in the photograph. 
 
 No. o. (. iab-lpuse ( Phthimus pubis ) magnified 80 diameters. Negative No. 510, new scries. In 
 this insect which is very similar in structure and habits to the head-louse, the sucking beak is also retractile. 
 Ihc specimen, which represents a female insect, is, however, so transparent that the outlines of the sucking- 
 apparatus can be seen in the photograph. Short anteunae project on each side of the head. The anterior 
 legs on each side are comparatively slender, the four others terminate in the great crab-like claws from 
 which the insect derives its name. Round openings into the tracheae such as are shown in the photograph 
 of the head-louse can be seen near the margin of the thoracic, as well as of the abdominal segments, and in 
 several places the trachea) themselves come into view through the transparent skin. The bristles which 
 occur on the abdomen and legs, are more sparsely scattered than on the liead-lousc. 
 
 No. 4. Louse of the dog (Hxmatopinus piliferous) magnified 80 diameters. Negative No. 515, 
 new series. 1 he general resemblance of this parasite to the human head-louse will at once arrest 
 attention. Aside, however, from technical distinctions, the swollen abdomen of the dog-louse aud the 
 great number of stout bristles with which it is beset will serve to distinguish it. It may here be mentioned 
 as a mattei ot interest that the popular idea that each animal has its own peculiar parasite, which occurs 
 on no other creature is not strictly correct. A number of instances are mentioned by Benny* of the 
 occurrence ol the same parasite ou several different animals. This would especially appear to be the case 
 ■'An essay on the British species of parasitic insects. By Henry Denny, London, 1842.— Preface. 
 
among birds, the same louse often infesting n number of allied species, but among quadrupeds such a com 
 munity of parasites is less frequent, The nuuibcr of different species is so large that as long a o 0 as 1H4_ 
 Denny figured over two hundred belonging to mammalia and birds, without doing much mote than makin 0 
 a preliminary survey of the subject. 
 
 Still more limited is our present knowledge with regard to the parasites of insects; as to which, 
 however, it is well known that many genera and species of the gamasiduc, a family ot the acarina or mites, 
 live parasitically upon the bodies of other animals, and especially upon the bodies ol insects. Two examples 
 are here offered selected from those species of the genus gamasus which occur parasitically upon beetles. 
 
 No. 5. Gauiasus of the soldier-beetle magnified 45 diameters. Negative No. 505, new series. 
 The prominent features of this mite, as shown in the photograph, are the oval body with eight hairy logs, 
 each terminating in a small double hook; and the remarkable appendages of the head, viz the two long 
 stout mandibles, terminating each in strong scissor-like extremities; externally to these are the curved 
 five-jointed hairy palpi or feelers. 
 
 No. fi. Appendages of the head of the same mite magnified 135 diameters. Negative No. 
 506, new series. The photograph displays in detail the external configuration of the mandibles and palpi. 
 One of the claws of the left hand mandible is broken. 
 
 No. 7. Gamasus parasite on the burying-beetle ( Necroptiorus ) magnified 50 diameters. Negative 
 No. 508, new series. This acarus is less hairy as well as smaller than that just described, its mandibles 
 are shorter and their scissors-like extremities more crooked, but a great similarity exists between the two. 
 
 No. 8. Anterior portion of the same gamasus magnified 135 diameters. Negative No. 509, new series. 
 In this picture the appendages of the head can be more minutely studied. 
 
 Not merely do the acarina furnish parasites for insects; many species exist upon the higher annuals. 
 Some, like the Deiuodex follieulorum, which lives upon the human face, are quite innoxious; others, like 
 the Sarcoptcs scabiei or itch insect of man, are the recognized causes of distressing skin diseases. 
 
 No. 9. Acarus found by Bourgogne, of Paris, on the bat, magnified 80 diameters. Negative No. o02, 
 new scries. The skin of this singular creature is beset with long hairs and each of the eight legs 
 
 terminate in double hooks. 
 
 No. 10. Parasite found by Bourgogne, of Paris, on a species of fly ( Volucella ) magnified SO diameters. 
 Negative No. 522, new series. This parasite, which would appear to be, probably, some immature insect. 
 I have been unable to identify. 
 
 The foregoing examples of insect parasites might be multiplied indefinitely did time and leisure permit, 
 and much more sihisfactory photographs could be produced if the specimens wore submitted to some pre- 
 liininary bleaching process. 
 
 I have the honor to be, General, 
 
 Very respectfully, 
 
 Your obedient servant,

L'Urr to the burgeon (intend oj the Army accompany ing seven photographs of the proboscides of 
 certain Jiies. 
 
 BRIGADIER GENERAL J. Iv. BARNES, 
 
 Army Medical Museum, 
 
 January 15, 1872. 
 
 Surgeon General, I’. S. Army. 
 
 General: The series of negatives of microscopic views of parts of insects, made by me during the 
 last Christmas hulidays, under the circumstances related in iny letter accompanying the photographs of the 
 Mosquito, embraces several views of the proboscides of certain flies, copies of which I transmit herewith, 
 with the following explanatory remarks. 
 
 The head of the common house fly, and of many other flies, bears, anteriorly, connected with its under 
 surface a flexible, fleshy, trunk-like, proboscis or sucking apparatus, by means of which the insect absorbs its 
 liquid food. Accounts of the structure of this organ are to be found in many entomological treatises, but 
 perhaps the most satisfactory is that given by Mr. B. T. Lownes in his monograph of ‘-The Anatomy and 
 Physiology of the Blow-fly,” (London, 1S70.) 
 
 Mr. Lownes justly declares the proboscis of this fly to be -‘one of the most remarkable and complex 
 structures found in the insect world.” He describes it as consisting of three joints, its hard parts being 
 the homologues of those usually found in the mouths of insects, but here greatly modified to fit them for 
 their special functions. The basal joint is moved at the pleasure of the insect by five pairs of muscles. 
 The walls of this joint are double and capable of being dilated into a cavity by the action of a pair of 
 strong muscles. By its alternate dilatation and collapse this organ acts as a pump to draw up the liquids on 
 which the insect feeds. The cavity is continuous behind with the oesophagus, and anteriorly with a hollow 
 tube in the second segment, which leads to the oral orifice. 
 
 I he terminal joint or segment of the proboscis consists of two large fleshy lobes, which, when at rest, 
 are folded together, but when the insect is feeding are opened so as to form an oval sucker divided 
 into two parts by a fissure which terminates posteriorly in a triangular orifice or mouth leading directly to 
 the sucking tube. These fleshy lobes arc channelled by numerous canals called false tracheae, which arc 
 kept open by incomplete rings, and which lead to the sucking tube just above the oral orifice. “These” 
 says Mr. Lownes, “form a fine strainer through which the insect is enabled to filter the fluid from the solid 
 portion of the substances on which it feeds.” 
 
 hor further particulars Mr Lowness monograph may be consulted. The above sketch will serve to 
 give some idea of these curious organs, which are but imperfectly shown in dried specimens such as were 
 used for the preparation of the photographs, of which the following is a brief description. 
 
 No. 1. Gives a general view of the Wine-cellar Fly ( Drosophila cellaris ) magnified 1G diameters. 
 Negative No. 532, new series. The photograph represents one of these flies carefully flattened out, so that 
 the proboscis protrudes from the extremity of the head. It gives an idea of the size of the proboscis as 
 compared with the bulk of the insect. 
 
 No. 2. Represents the same proboscis magnified 80 diameters. Negative No. 533, new series. 
 
 No. 3. Represents the same magnified 1&5 diameters. Negative No. 535, new series. Both No. 2 
 and No. 3 distinctly show the numerous transversely marked, false tracheae of the sucking lobes, the tube 
 of the second joint, and the thick massive first joint, which also has attached to it on each side two curious 
 
club shaped organs well beset with bristly hairs ; these are the palpi or feelers which some naturalists 
 indeed believe to be more than mere feelers, organs perhaps of smell, taste, or even of both. 
 
 No. 4. Represents the proboscis of the Blow-fly {3fusca votnitoria) magnified 42 diameters. Negative 
 No. 536, new series. Considerable difference will be observed in the size and form of the sucking lobes, 
 the number and shape of the false tracheae, the shape of the palpi, &c., but the general structure is quite 
 similar to that of the proboscis of the Wine-cellar Fly. 
 
 No. 5. Exhibits the fleshy lobes of the same proboscis magnified 80 diameters. Negative No. 540, 
 new series. In this picture the false trachea? and their circular rings, the central cleft between the two 
 lobes and the triangular oral orifice, are well seen. The sucking tube of the second joint being dark-yellow 
 in the preparation appears as a black streak in the picture. The size and arrangement of the bristles 
 which beset the second joint and fringe the sucking lobes are worthy of notice. 
 
 No. 6. Represents the proboscis of the common House-fly ( Musca dome&tica) magnified 85 diameters. 
 Negative No. 541, new series. The parts are essentially the same as those of the Blow-fly though smaller 
 and somewhat modified in form. In the preparation copied, the second joint of the proboscis has been 
 broken and a part of its outer membrane turned to the left. 
 
 No. 7. Represents the proboscis of the Zone-fly ( YoluceUa zonarid ) magnified 40 diameters. Nega- 
 tive No. 450, new series. This fly, in size and general appearances, resembles the llumblu-bee. Availing 
 herself of this circumstance the female fly enters the nests of the bees and lays her eggs, to hatch out 
 voracious larva? which prey upon the larva? of the bee. The photograph is added chiefly because it exhibits 
 the fleshy lobes of the proboscis, which is similar to those already described, in a partially collapsed con- 
 dition. In the lower part of the picture, on the right hand side, may be seen a combination of lancets, 
 produced by special developments of the maxilla?, mandibles, and tongue, (Lownes, loc. cit. p. 45.) which 
 do not correspond to anything shown in the other pictures, and which therefore need no special comments 
 in this place.

 BRIGADIER GENERAL .J. Iv. BARNES, 
 
 Surgeon General. I'. S. Army. 
 
 General: I transmit herewith prints of eleven miscellaneous photographs, of insects and parts of 
 insects, made during the late Christmas holidays under the circumstances explained in my letter accompa- 
 nying certain photographs of the Mosquito. 
 
 The following is a brief description of the present series. 
 
 No. 1. Clawed Water-bug (larva of Xaucoris cancroid es) magnified 19 diameters. Negative No. 
 503, new series. This is the aquatic larva of an hemipterous insect. The posterior four legs are used in 
 swimming. Anteriorly are two powerful grasping claws. 
 
 No. 2. Sailor beetle (a species of Jlydroporus ) magnified 19 diameters. Negative No. 504, new 
 series This is a small carniverous aquatic beetle. The preparation was so yellow that many details are 
 lost, but the head with its forceps-like mandibles or jaws and its many jointed antenme, the anterior dense 
 wing cases or elytra;, the posterior more delicate wings, and the six legs are tolerably well indicated. 
 
 No. 3. Head of beetle magnified 15 diameters. Negative No. 513, new series. In this view of the 
 head and anterior portion of the body of an unidentified beetle (probably a species of Tenebrio ) the toothed 
 forceps-like mandibles, and the jointed antennae are more plainly shown. The mandibles or jaws of these 
 insects work sideways, and not as in vertebrates up and down. They- are flanked by the jointed palpi or 
 maxillary feelers, while externally the many jointed antenna) come into view. 
 
 No. 4. Part of the Eye of a beetle, magnified 400 diameters. Negative No. 517, new series. Few 
 objects connected with entomology are more wonderful than the compound eyes of insects. The optic 
 nerves instead of leading to vast numbers of rods and cones united into a siugle layer as in the eyes 
 of the higher animals, terminate in a rather smaller number of cones and rods, each of which corres- 
 ponds to a separate lens covered by a separate hexagonal segment of cornea. Considerably over a hundred 
 of these segments are shown in the photograph, which represents a very small portion of one of the 
 compound eyes. The precise number has been differently estimated by entomologists but in many species 
 amounts to several thousands. 
 
 No. 5. Foot of Cockchafer (. Melolontha vulgaris ) magnified 80 diameters. Negative No. 514, new 
 series. This beetle, so famous in the child-literature of Europe, is interesting in many particulars. The 
 specimen from which the present photograph was taken serves to exhibit the anchor-like terminal hooks of 
 one of the legs. 
 
 No. 0. Belted Wasp-fly ( Syrphus balteatus') magnified 12 diameters. Negative No. 511, new series. 
 This small but graceful fly exhibits at a glance many of the characters of dipterous insects. The head 
 bears two long jointed antennae between which projects a needle like lancet or sting. The sucking tube 
 to which this lancet belongs has been displaced in making the preparation and is seen externally to the 
 left antennas. 
 
 No. 7. Buccal organs of llmiey-bee (Apis mellijica) magnified 38 diameters. Negative No. 51G. 
 4 he photograph exhibits the following parts. Centrally is seen the long flexible tongue or 
 
 new series. 
 
proboscis (Ifala) with which the sweet juices of plants are taken up. ' This is marked by a great number 
 of transverse lines and beset with numerous hairs. On each side are the jointed labial palpi or feelers, 
 while still more externally come the trowel-like maxilla?, which being concave inwards are used sometimes 
 to ensheath the more delicate proboscis to enable it to penetrate into the depths of flowers, at other times 
 perhaps to aid in smoothing and finishing the wax cells of the honey comb. 
 
 No. 8. Buccal organs of Dragon-fly ( Calopteryx ) magnified 40 diameters. Negative No. 520. new 
 series. This photograph exhibits the formidable toothed mandibles of this carniverous" insect. 
 
 No 9. Ovipositor of Saw-fly ( Cimbex Americana) magnified 80 diameters. Negative No. 512, new 
 series. The Saw flies, with their curious saw-like ovipositors, make slits in the leaves of shrubs and trees 
 and there deposit their eggs. In several genera of these flies the deposition of the egg is followed by the 
 development of a gall-like excrescence on the leaf in which the larva is hatched out. 
 
 No 10. \oung Spider (not identified) magnified 38 diameters. Negative No. 520, new series. This 
 picture simply gives a general view of the conformation of a minute spider, showing the palpi, eiirht le^s 
 and body, all well covered with bristle-like hairs. 
 
 No. 11. Portion of the Buccal organs of a Spider magnified 19 diameters. Negative No. 51 0. new 
 senes. Below are seen the two powerful mandibles, each consisting of two joints, the lower being a 
 crooked claw through which the secretion of a poison glaud passes into any thing transfixed; above are 
 the curved hairy maxillary palpi or feelers. On the right is seen one of the palpi of a second head 
 mounted in the same preparation.

 Dear Mr. Wood t 
 
 I thank you very much for our pleasant telephone 
 conversation last evening regarding the enclosed copy 
 of Photo-Micrographs of the Mosquito & C. (ca. 1872) 
 by Dr. Joseph Janvier Woodward. The book is in much 
 better condition than I originally thought and contains 
 all 34 mounted micro-photographs of various insects 
 and insect anatomies. 
 
 The volume does not lack a title page or frontis- 
 piece and my own limited research — as well as haphazard 
 experience — reveals that very few government publications 
 contained either of these. With the exception of the 
 partially missing text on page two, the copy is 
 complete . 
 
 The provenance of this particular volume is as 
 follows: The book was purchased September 15 , 1973, 
 
 from the Estate of Anabel D. Shif f erstine , 21 Hunter 
 Street, Tamaqua , Schuylkill County, Pennsylvania. 
 Photo-Micrograohs was included in the public auction 
 which incorporated the collections, libraries, and 
 holdings of Dr. C.B. Dreher, Dr. Edgar E. Shif f erstine , 
 and Anabel Dreher Shif f erstine . 
 
 Following inquiries to several book dealers and 
 rare book room librarians (who, unf ortunately , do not 
 specialize in this type of book and who, frankly, are 
 not familiar with the work of Dr. Woodward), I tend to 
 believe this volume is as scarce as it is unusual. 
 
 I hope you enjoy examining this interesting 
 volume; if it should merit your consideration regarding 
 an offer to purchase, please feel free to call me at 
 my home after five o'clock. 
 
 Again, my thanks for your cordial telephone 
 
 call. 
 
It
