Applied botany.— KRAEMER‘ has accomplished a very laborious task for 
the benefit of students in technical schools, pharmaceutical and medical 
colleges, food analysists, etc. Although emphasizing the technical side of 
with the scientific aspect. The seven chapters include the following subjects: 
Principal groups of plants, under which is given an outline of the plant king- 
m; Cell contents and forms of cells; Outer and inner morphology of the 
higher plants; Botanical nomenclature, which is also a glossary of technical 
terms; Classification of angiosperms yielding economic products; Classification 
of Fp oe plants; and Microscopic technique of reagents. 
e book is a thesaurus of information, and as a book of reference should 
be Z great service to botanists in general.—J.M.C.

Toxic effects.—The observation that small traces of salicylic acid (o-oxy-

zoic acid have a deleterious effect on the growth of Penicillium, while both 
p-oxybenzoic and m-oxybenzoic acids serve as food, has led BOESEKEN and
