all vegetable drugs, the name of the plants from which they are 

 derived and the countries from which they come, a description of 

 each drug, its constituents, allied plants from which a similar 

 drug may be obtained, and the articles, if any. with which it is 

 adulterated. These are arranged under such heads as seeds, 

 roots, barks, etc., with keys for their identification. Since a 

 large number of drugs come to market in powdered form, and 

 therefore not easily recognizable, the author has, in the section 

 devoted to powdered drugs, given keys and descriptions by which 

 these may also be identified. It would doubtless be difficult for 

 a careful student of this work to go wrong on the botanical re- 

 quirements of pharmacy, and the general reader who is in- 

 terested in the constituents of plants will find it a veritable mine 

 of information. In the interests of the latter, we cannot but 

 wish that the medicinal properties of each drug had been includ- 

 ed, although aware that this belongs to materia medica rather than 

 to pharmacy. The book admirably fills the place for which it 

 was designed and should supplant the ordinary botanical text 

 books in schools of pharmacy. 



"Among Green Trees"t is, as one might surmise from the 

 title, more of a book about trees than a manual for their identi- 

 fication, although this part of the subject has also received 

 attention. The first division of the book deals with "the nature 

 study side'' as indicated by such subjects as the flight of seeds, 

 the battle among the twigs, thorns and prickles, winter buds, etc. 

 Following this is "the physiological side," where will be found 

 information about how trees breathe, feed, and sleep, why they 

 die, etc. In "the practical side" are given directions for planting 

 and pruning trees and many other matters relating to forestry, 

 insect pests, etc. In "the systematic side" about 125 different 

 species of forest trees are described. The book is very well il- 

 lustrated, there being twenty-five full page photographs of speci- 

 men trees and numerous illustrations in the text. The author 

 has a clear and pleasing style, though there are occasional mis- 

 statements in the text regarding various processes of plant 

 life.
