22 PLANT PHYSIOLOGY. 



Verworn's ''General Physiology,' though most of it is not 

 botanical. Goodale's "Physiology," though much behind the 

 present state of knowledge, is a useful synopsis of some topics, 

 and Sorauer's "Popular Treatise " has considerable value for 

 the economic aspects of the subject. Schimper's " Pflan- 

 zengeographie ' is indispensable for the ecological phases of 

 physiology. A recent and readable summary of the subject is 

 Green's " Introduction to Vegetable Physiology. ' Again, it is 

 very profitable in connection with experimentation to read 

 another work upon the experimental phases of the subject, and 

 for this nothing is better than Detmer's " Practicum, ' trans- 

 lated into English by Moor under the title "Practical Plant 

 Physiology. ' The student should read this book as regularly 

 as Pfeffer's, in both cases after the laboratory work on the par- 

 ticular topics. It is well also to consult Darwin and Acton's 

 "Practical Physiology' and MacDougal's "Experimental 

 Plant Physiology.' MacDougal's "Nature and Work of 

 Plants ' has many suggestions for elementary physiological 

 study.
