REVIEW. 
us, since lectures on chemistry usually embrace these subjects, a 
treatise on that science, be it ever so brief, cannot well omit en- 
tering in full upon them, or at least considering them in their con- 
nection with chemical phenomena. In Germany, we presume that 
students are left to obtain the necessary information while prose- 
cuting the study of physics, for which, in the larger universities, 
a distinct professorship exists. Matters pertaining to operative 
chemistry, such as solution, evaporation, fusion, etc., are then 
briefly explained ; after which follows a list of the chemical equiva- 
lents, and a valuable comparative table of the various medicinal 
weights in use in the various German states, and in foreign coun- 
tries. The gases, and such of the other non-metallic elements as 
are important in a pharmacological point of view, are then con- 
sidered. Here the arrangement of the author is comprehensive 
and peculiar, and, indeed, not without advantage, since his classi- 
fication allows him to bring in, arranged in proper groups, accord- 
ing to their ultimate constituents, not only the inorganic com- 
pounds, but also the azotized and non-azotized organic bodies. 
Students are thus enabled more easily to comprehend and recollect 
the relationship which may exist between one group and another. 
The rest of this division is taken up with outlines of the metals ; 
since the major portion are officinal, they are mostly referred to 
the second part. 
The second part considers only chemical remedies. The acids, 
ethers, alkaloids, alkaline and metallic salts, together with such 
of the distilled waters as may involve chemical principles and 
changes in their preparation, are treated alphabetically and in a 
methodical manner. The synonyms, outlines of preparation, pro- 
perties, various means of recognition, tests for impurities, and 
therapeutic application, are severally discussed under distinct 
heads ; to which is added, if the substance under consideration be 
a poison, its antidotes and other points of toxicological import- 
ance. The Latin nomenclature adopted by our Germanic breth- 
ren differs slightly from our own. For instance, Aqua calcariae 
Chinium sulfuricum ; natrium-stibato-sulfuratum, or sulpho-stibias- 
natricus, if there be a choice. Among the synonyms of tartarus 
boraxatus is given tartras-borico-natrico-kalicus ; these compound 
terms, however, belong to a bygone period. The German itself 
is not unfrequently quite as formidable. Take as a specimen :
