in view. He was first in the work of establishing the Marion County Medical Society, in 1847, and he was prominent in helping to organize the State Society of Indiana in 1849. In both societies he was an active and prominent member. In 1868 he was elected president of the Indiana State Medical Society. His inaug ural address was upon "The Necessity of a State Medical Journal and a Medical College." His paper on lithotomy of the gall-bladder, from which my report of the operation is taken, was published in the same volume of the transactions with his

presidential address. The latter part of Dr. Bobb's life was devoted mainly to surgery. He was well read in the literature of his specialty, and as an operator he was bold and original. Like most of his contemporaries, he was not a frequent contributor to medical literature. Dr. Jameson, in the paper which I have quoted, mentions an operation in which he assisted, in which Dr. Bobbs removed the superior maxillary bone together with the eye of the affected side for extensive carcinoma. The operation lasted several hours, but the patient made a good recovery. The hemorrhage was so well controlled that little blood was lost and the patient recovered from the operation and was much more comfortable afterward. He also mentions a successful operation for extra-uterine pregnancy and an unsuccessful operation for umbilical hernia. Dr. Bobbs was a brigade surgeon during the Civil War, and in the latter office he was medical director for the district of Indiana. During the Civil War he was with the staff of General Morris, of Indianapolis, and showed his courage by bringing off the field under fire a soldier who was fatally wounded.

Besides his professional services, Dr. Bobbs was a public-spirited man who took active part in the affairs of his city and state. For one term he served as state senator. He was one of the original commissioners who organized the Indiana Hospital for the Insane, and he gave liberally to general charitable purposes. In person he was slender, of medium height with striking features. His forehead was high, his eyes dark grey, his nose large and aquinline, his chin prominent. He generally wore a suit of black broadcloth

and a silk hat, and had the manners of the old-style gentleman.

He may be truly considered one of the founders of scientific medicine and surgery in the middle West. As the greatest general surgeon and teacher of his day in that section of the country, as a publicspirited man and soldier, his name will long be remembered in the region in which he practiced.

Several others besides Bobbs did valuable pioneer work in gall-bladder surgery, but there is no evidence that I have been able to find that any one, at an earlier date, ever opened the gall-bladder after celiotomy.

ANATOMY FOR THE PRACTITIONER.*

BY CLARENCE M. JACKSON, M. S., M. D., Assistant Professor of Anatomy and Histology, University of Missouri, Columbia, Mo.

The post-graduate study of gross anatomy, normal and pathologic, is for the practitioner a subject of great importance. There is a strong necessity for a continued review of these fundamental subjects, in order that clinical procedure may rest on a scientific basis. A mere book review, however, on which the great majority of practitioners are obliged to depend, is very inadequate. How then shall the practitioner review his knowledge of practical anatomy? The ideal method is, doubtless, for the practitioner to attend from time to time the post-graduate courses in normal and pathologic anatomy offered in the leading medical schools. Here he will find an abundance of material, well-equipped labortories and valuable assistance from the instructors. Only a small percentage of the practitioners, however, are fortunate enough to be able to take advantage of these facilities. For numerous reasons such courses are inaccessible

to the great majority. It is the purpose of the present paper, however, to call attention to numerous opportunities for the home study of practical anatomy which are open to every practitioner who is willing to devote a little time to the subject.

states except South Dakota and South Carolina. From these replies it appears that in regard to their anatomic laws, the states and territories may be divided into three classes, nearly equal in size: 1. Those in which there is no statute whatever relating to the subject. This class includes Alabama, Arkansas, Arizona, Delaware, Florida, Idaho, Indian Territory, Montana, Mississippi, North Carolina, New Mexico, Oklahoma, Rhode Is

land, Texas, Utah, Washington, and Wyoming. 2. Those in which dissection. is legalized but only medical schools are entitled to cadavers. This class includes Connecticut, Colorado, District of Columbia, Georgia, Indiana, Kansas, Kentucky, Louisiana, Minnesota, Michigan, New York, Ohio, Pennsylvania, West Virginia. 3. Those in which, under certain conditions, practitioners as well as medical schools are entitled to cadavers for dissection. This class includes California, Iowa, Illinois, Maine, Maryland, Missouri, Massachusetts, Nebraska, New Jersey, New Hampshire, North Dakota, Oregon, Tennessee, Vermont, Virginia, Wisconsin. The restrictions under which practitioners may obtain cadavers vary somewhat in the different states. A bond is usually required to guarantee the use of cadavers for scientific purposes only. Most states specify that the needs of the medical colleges shall be met before cadavers are available for practitioners. No one, I presume would question the justice of this rule, since dissection is absolutely necessary in the medical schools. point to be emphasized is this: The medical profession in every state should demand a law appropriating for anatomic uses all bodies to be buried at public expense. This law, properly enforced, would secure an abundance of material for practitioners as well as for medical schools. The difficulty usually lies in the vigilance necessary to secure an enforcement of the law. It should be the duty of the physicians in each locality to see that the law is enforced, in order that sufficient material for all who desire it may be provided. An excellent provision in the New Jersey law requires physicians who wish to dissect to organize themselves into an anatomic and pathologic association (of three or more) for the advance

ment of medical and surgical science. The Wisconsin law provides that such work may be done under the auspices of the county medical societies, an idea which I shall discuss later.

USES OF FETUSES.

But are there no opportunities for practitioners who for any reason are unable to procure cadavers? There are many. First, let me call your attention to the neglected opportunities in the way of fetal specimens. Advanced fetuses are fairly abundant, easily preserved, and valuable for anatomic study. A full term fetus in many respects makes an excellent substitute for an adult cadaver. A careful

study of such material is also of great peculiarities incident to infancy and childhood, a subject of especial interest to those concerned with diseases of children.

value in demonstration of the anatomic

In passing, let me say that fetal specimens, especially the earlier stages, would be very thankfully received at almost any anatomic laboratory, in case the physician did not wish to keep them. Methods of preservation are given below.

Another source from which valuable material may be derived for the study of normal and pathologic anatomy, especially of individual organs, is from specimens obtained at operations and postmortems. A little zeal combined with tact can accomplish a great deal in this line. Think of the amount of material which might be used for anatomic study, but which is thrown away and absolutely wasted. This state of affairs, I believe, is due largely to the fact that few practitioners know how to preserve properly and to make use of such material.

The remainder of this paper will, therefore, be devoted to the explanation of a few simple methods, which may, perhaps, be of some practical value. Of these, three will be given: 1. To preserve a cadaver for ordinary dissection. 2. To cut a body into sections for topographic study. 3. To preserve individual organs with their natural colors (Kaiserling's method).

PRESERVATION OF CADAVERS.

To prepare a cadaver for ordinary dissection, it should be embalmed by the arterial injection of some fluid which will preserve the body indefinitely, and yet re

tain as nearly as possible the natural consistency and color of the various organs. Many fluids are in use for this purpose, the best of which, in my experience, is the alcohol-carbolic acid-glycerine mixture. It is made by mixing together equal parts of strong alcohol (95 per cent.), melted carbolic acid crystals and glycerin. The method of embalming is very simple. Cut down to an artery (common femoral preferred), and inject the fluid with any available injection apparatus. I have seen an ordinary rubber-bulb hand syringe used with perfect success. The main point is to keep up a strong pressure until the fluid has penetrated through the arteries to all parts of the body. It will require about an hour of time, and six to eight quarts of the fluid. After twenty-four hours, when the arterial pressure has gone down, a colored mass may be similarly injected. Equal parts of plaster of paris and starch, ground up with red lead, sifted carefully, and mixed with water to a

which case it is advisable to freeze the body (with salt and ice mixture) before cutting into sections. The figures presented are from specimens prepared in this way. The immense practical value to be derived from a study of the body sectioned in this manner needs no emphasis.

PRESERVATION OF INDIVIDUAL ORGANS IN

COLORS.

The third method applies chiefly to individual organs or parts. The cheapest liquid in which to preserve specimens is 5 per cent, formalin (2 per cent. formaldehyd), which costs only ten or fifteen cents per gallon. The following (Kaiserling's) method is more expensive and more tedious, but has the great advantage of preserving the natural colors of the various organs, both in normal and pathologic conditions.

Two separate fluids are required:

A.-FIXING AND HARDENING FLUID.
Formalin, (40 per cent. formaldehyd),

Watch the cadaver closely for several days after embalming. part shows signs of decay (due to imperfect injection), give it local hypodermic injections of formalin (25 per cent.). After having been embalmed perfectly the cadaver will keep indefinitely. Drying is to be prevented by wrapping in waterproof cloths, or placing in an air-tight box or can. The great advantage of an embalmed subject is that you can dissect at your leisure, a point of no small importance to the practitioner.

MAKING SECTIONS.

The second method, that of sectioning a body for topographic study, was given by me in a paper before this association last year. The details of the method were published in THE JOURNAL September 21, 1901, and need not be repeated here. Briefly, the method consists in the arterial injection of 50 per cent, formalin, which hardens the body so thoroughly that it can readily be cut, with a long knife and saw, into sections for study. By decalcifying in 5 per cent, hydrochloric acid for several weeks after hardening, even the saw may be dispensed with. The accompanying specimens show what can be accomplished by this method. Like the first method it can be applied to advanced fetuses, in

The above amounts are sufficient for an organ of the size of the human liver.

The procedure is as follows: After removing the fresh organs, place them in a vessel on cotton, cover well with solution A and place in the dark for four to eight days, according to the size of the specimen. Liquid should be changed once after twenWhen thoroughly fixed ty-four hours. and hardened, the specimen, after draining a few minutes, should be placed in 95 per cent. alcohol for a few hours (not over six hours), which restores the natural color. The specimen is then placed in a glass vessel containing solution B, which preserves it indefinitely. indefinitely. Specimens when not in use should be kept in a dark place, otherwise the colors are liable to fade out in time. Specimens preserved by this method may be dissected later, if desired.

MUSEUMS FOR SOCIETIES.

In conclusion, let me emphasize a point previously referred to. Why could not each local or county medical society es

logic anatomy of all parts of the body? Some energetic and enthusiastic member could always be found who would be willing to act as curator. The society could take advantage of the law allowing scientific organizations to import glassware, regents, etc., duty free, thus reducing the cost to a minimum. Would not a series of demonstrations from such a museum add materially to the interest and value of the meetings? The collection, even though small at first, would gradually in

Discussion.
