The committee is grateful for the privilege of rendering this public service, for, as in Carlyle's time, “ the true university is a collection of books,” expertly selected and properly used.

“ prospect” would become interested in the chemical subjects discussed; and consideration of this view and the results of its own inquiry convinced the committee that, to accomplish the purposes desired, the reading courses should have a very definite publicity plan behind them.

In carrying out its work, the committee has prepared the manuscripts for a series of circulars which, it is thought, will make men want to read chemical literature. In order to accomplish that result, the committee has written lively and appealing essays, of about 1,500 words each, on elementary chemistry, household chemistry, general and physical chemistry, inorganic and analytical chemistry, organic and biological chemistry, industrial inorganic chemistry, industrial organic chemistry, and techno-chemical analysis, all of which have been divided into appropriate paragraphs, worded so as to bring out the importance of the subject and so as to impress the reader with the national essentiality of the chemical profession. Carefully selected books are mentioned casually in the texts of the courses, usually to conclude the paragraphs.

These courses should now be made available for the use of librarians who wish to reach ambitious persons who have the intelligence to follow a course of chemical study. They should, to serve the intended purpose, be published in attractive booklet form for distribution at libraries to persons who are engaged in chemical work or interested in the specific subjects of the various courses, and to persons who are as yet only casually engaged or interested, but who may think of becoming wellinformed on chemical subjects.

It is therefore recommended that the committee be authorized to furnish Mr. Joseph L. Wheeler with copies of the manuscripts, in order that he may endeavor to arrange for their publication in toto, and that the present committee be designated to cooperate.with Mr. Wheeler in that undertaking and in stimulating interest in chemistry through the media of libraries. It is also recommended that the courses be published by the society in The Journal of Industrial and Engineering Chemistry.

SPECIAL ARTICLES
AN UNEXCELLED MEDIUM FOR THE

PRESERVATION OF CADAVERS One can not contemplate the history of human dissection without a profound sense of gratitude for the discovery of three chemicals, the use of which in embalming has completely transformed the laboratory of gross anatomy. Could they have been introduced earlier, human dissection long since would have lost its forbidding aspect. Although Scheele discovered glycerin in 1779, it was not used for the preservation of anatomical material until 1868, almost a century later. This was not until a year after formaldehyde had been discovered by Hoffman and, although the antiseptic properties of the latter were not revealed till twenty years later. this event soon was followed by its introduction into histologic and gross anatomic technique in 1890 by Blum, junior and senior respectively, The earlier discovery of phenol by Runge in 1834, with the subsequent relation of its antiseptic properties by the revolutionary usage of it in surgery by Lister in 1867, and its application in the preservation of anatomic material by Laskowski in the same year, or even in 1864, completes the trinity of substances so largely responsible for freeing dissection of the human body from the noisome burden previously imposed by post mortem decay. An occasionally delayed necropsy still can suggest to present-day medical students just what this freedom meant to anatomists and students of anatomy of the past. Surely nothing has been a greater boon to human anatomy and anatomists than the miracle wrought by these and other chemicals, the proper use of which bids fair to make our anatomical laboratories practically odorless.

For unless the bodies can not be obtained soon demands not only a considerable initial exenough after death to make proper preserva- pense, but also imposes a relatively high cost tion possible, the human anatomist or medical of maintenance.
