In his first volume on "The Tannins" Prof. 

 Trimble confined himself to a discussion of the 

 tannins as a class and the tannins of nut-galls 

 which may be said to stand by itself. In the 

 present volume the auther considers the physio- 

 logical tannins: Oak bark. Mangrove, Canaigte 

 and Cliestnut. In the study of this class of plant 

 constituents the author has considered them 

 from the standpoint of the analytical chemist 

 preparing the way for the pliysiological botanist. 

 It is very apparent that we must first know how 

 to obtain a tannin from its source, not neces- 

 sarily quantitatively', then we must learn to 

 know its physical and chemical properties, and 

 finally its composition and constitution. Having 

 accomplished this much we are in a position to 

 devise a method of quantitative estimation. After 

 this its physiological relations may be under- 

 stood. After some attempts in each of the above 

 mentioned departments, the author has decided 

 that the only logical method of pursuing this 

 study is to take up the individual tannins in the 

 following order ; 



1. The source from which each may be ob- 

 tained. 



2 . Collect what has been accomplished by 

 others ; that is, study the history. 



3. Devise a method of preparation adapted to 

 the peculiar tannin under consideration. 



4. Determine as far as possible its purity, 

 then its physical and chemical properties, com- 

 position and constitution. 



5. Construct an accurate and rapid method of 

 estimation. 



The botanical illustrations of the leaves and 

 acorns of the oaks are especially well done. It 

 is highly probable that no work has appeared 

 since the time of Michaux in which the plates 

 are so accurately done and so true to nature.
