Handbook of Systematic Urinary Analysis, 
Chemical and Microscopical.— By Frank M. 
Deems, M. D. — The Industrial Publication Company, 
New York, 1880. 
As a laboratory instructor in the medical department 
of the University of the city of New York, Dr. Deems 
must have acquired just the right sort of knowledge to 
fit him to write such a work. 
The aim of the author appears to have been to offer a 
concise manual on urinary analysis, and to accomplish 
this end he has tabulated and arranged a large amount 
of matter, so that within a few pages and almost at one 
view the essential details of the subject are presented in 
a form for very rapid reference. 
Several small handbooks have been recently published 
on this subject, which bear a remarkable likeness to ODe 
another, and we are glad to see that Dr. Deems has struck 
out in an original course, and produced a useful book 
which does not pretend to take the place of the larg- 
er works, but will be found of special value to medical 
students and physicians who require a synopsis of all the 
facts which it is important to remember in actual prac- 
tice. 
SOCIETY OF AMERICAN TAXIDERMISTS. 
The first annual exhibition of the “Society of Ameri- 
can Taxidermists,” was held at Rochester, N. Y., com- 
mencing Dec. 14th and continued eight days. This So- 
ciety, which is national in its character, was organized in 
Rochester, March 24th of the current year, with F. S. 
Webster as President and W. F. Hornaday, Secretary. 
It now numbers over forty active members besides 
several honorary members. Its scope is to advance the 
interest and raise to a higher standard of excellence the 
work in the line of science which its name indicates. 
The exhibit consisted of about one hundred cases of 
birds in groups and perhaps twice that number of indi- 
vidual specimens ranging from a humming bird to an 
American Bison. 
Perhaps the neatest thing, as “ a thing of beauty,” was 
a white heron mounted as a medallion on black velvet in 
an appropriate frame — the work of Mr. Webster. 
The next meeting will be held at either New York or 
Boston, and as the initiatory one at Rochester was very 
successful in a pecuniary way, it can hardly fail of suc- 
cess in a large city. 
The American Chemical Society will hold its first 
meeting of 1881 on Monday evening, January 3, at Room 
No. 1, University Building, Washington Square,
