128 THE AMERICAN BOTANIST 



describing the diseases that infest our cultivated plants. Since 

 plant diseases do not vary with the author, the merits of a 

 book depend upon the way the subject is treated. Duggar's 

 book discussed each disease under the organism that causes 

 it, the present volume treats of the diseases as they are found 

 affecting the various species of plants. No attempt is made to 

 describe the organisms that cause the disease the whole atten- 

 tion being given to the characteristic features of the disease 

 itself and the methods of treatment. In these matters the 

 book is both full and satisfactory. The diseases are treated 

 under such heads as those infecting trees and timber, those af- 

 fecting ornamental plants, forage crops, tropical plants and 

 the like. The attempt of the authors to make a common 

 name for each disease by adding ose to the name of the casual 

 fungus is, in the opinion of the reviewer, scarcely successful. 

 To call dry rot of the potato lasiodiplodiose, for instance does 

 not seem to help matters. The book contains many good il- 

 lustrations and nearly five hundred pages of text. It is pub- 

 lished by the MacMillan Company at $2.00 net. 



Three years have elapsed since the appearance of Stevens 

 "Plant Anatomy" and now we have a second edition revised 

 and enlarged by the addition of a chapter on evolution and 

 a number of illustrations. Although the book is well known 

 to students it may not be amiss to call attention to the fact 

 that it takes up botany from the standpoint of the develop- 

 ment and function of the tissues and beginning with the cell 

 shows how it has been modified to form the various tissues 

 found in the plant body. Especially to be noted with approval 

 are the numerous explanatory diagrams of plant parts and the 

 suggestions for additional studies. Though larger than the 

 first edition the price remains the same, $2.00 net. It is pub- 

 lished by Blakiston, Philadelphia.
