REVIEW.

no small portion of all our materia medicas must necessarily be 
devoted to observations on chemical remedies. Leaving, for a 
moment, all other works out of the question, every apothecary has 
a complete digest of such information, and also much that is 
strictly pharmaceutic in its character, in what was long since the 
sine qua non of an American pharmaceutical establishment, the 
United States Dispensatory. There is no doubt, however, that a 
work which would in a certain degree comprehend both branches 
of the subject, and yet be sufficiently general and elementary in its 
details to form a text-book adapted alike to students of pharmacy 
and medicine, could not but be well received. 
Of such a class is the volume before us. Germany, indeed, ap- 
pears to be favored in this respect. Works on pharmaceutical 
chemistry and on chemical pharmacology abound. Dr. Duflos, our 
author, has published a number of books, all more or less connected 
with the subject. The work under consideration consists of im- 
proved editions of two previous publications, bound in one, yet re- 
taining their distinct characteristics, being paged separately, and 
having different registers of contents. As now published it con- 
sists of four parts. The first part, originally issued under the title 
" Pharmacological Chemistry," was designed, as we are informed 
by its title page, " as a text book, and for the use of practical and 
judicial physicians and surgeons."* It contains one hundred and 
seventy for the most part closely printed pages, and resembles our 
own text books of general chemistry ; the brief notices of prepara- 
tions, however, and the attention to points of interest and import- 
ance to pharmaceutists and physicians, wherever such reference 
may be indicated, give it a technical appearance. 
The first fifty pages are devoted to the fundamental principles of 
the science. The difference between organized and inorganized 
bodies is explained ; then heteromorphism, isomorphism, absolute 
and specific weight, the combining proportions, chemical symbols, 
and so on, are duly considered. But little is said of light and 
heat, beyond noticing the light and heat capacity, and the influ- 
ence of the latter on cohesion, and on the forms and properties of 
bodies. Electricity and magnetism are entirely omitted. With 
* Practical physicians are those who have received the degree, and who 
have also passed through the ordinary hospital course. The judicial phy- 
sician is a post somewhat similar to that of our coroner.
