CHEMICAL REMEDIES AND POISONS; THEIR PROPERTIES, RE- 
COGNITION, TESTS, AND THERAPEUTIC APPLICATION. By Dr. 
Adolf Duflos, Adjunct Professor of Chemistry in the University of 
Breslau, etc. Second Edition. With special reference to the latest Phar- 
macopoeias. Breslau. 704 pp. octavo. 
The rapid progress of modern chemistry may be in a great mea- 
sure attributed to the arduous research, and the many discoveries 
of startling brilliancy which characterized the declining years of 
the last, and the earlier portion of the present century. More re- 
cently, rapidity of development has been quite as remarkable ; and, 
as the science becomes more complete, it naturally becomes more 
diffused, and more universal in application. Consequently, we 
now make distinctions which in former years would have been im- 
practicable. Thus, we have chemical works with various titles, 
indicative of what special branch they may expound ; on theo- 
retical and practical chemistry, for instance, on animal, and agri- 
cultural chemistry, and also on chemistry applied to most of the 
arts and manufactures. Although pharmaceutical chemistry has 
by no means lagged behind other branches, its literature, so far as 
the English language is concerned, is meagre, and has not flour- 
ished in a ratio corresponding with its increasing elevation and 
practical importance. This is particularly observable in the 
paucity, or rather absolute want of proper text books on the 
subject. 
In regard to pharmacological chemistry, or that branch which 
considers the properties and uses of chemical remedies, if indeed, 
in its usual acceptation, the term does not also include the practi- 
cal or pharmaceutical department, the same cannot be said, since
