Experimental Physiology. 9 



This course, which forms a natural sequence to Course 13, 

 offers opportunity for more extended study of special 

 cases of morphological adaptation under artificial as well 

 as natural conditions. Changes of form and structure in 

 Proserpinaca, Polygonum and other plants are under 

 investigation together with certain aspects of zygomorphy 

 and other problems of experimental morphology. Among 

 the works most in use are Goebel, Organography of 

 Plants; Haberlandt, Physiologische Pflanzenanatomie ; 

 Davenport, Experimental Morphology; and Goebel, 

 Pflanzenbiologische Schilderungen. 



SECOND SEMESTER. 



8. Plant Pathology. Lectures and laboratory work. Three 

 hours. Dr. POLLOCK. 



In this course the aim will be to secure familiarity with 

 the structure, habits, and life history of leading groups 

 of fungi, special attention being given to those determin- 

 ing pathological conditions of cultivated plants. Suffi- 

 cient time will also be given to bacteria and other patho- 

 logical agents to secure a foundation for independent 

 work in this direction. Among the works most used 

 are v. Tubeuf, Diseases of Plants induced by Crypto- 

 gamic Parasites; De Bary, Fungi, Mycetozoa, and Bac- 

 teria; Schroeter, Die Pilze (in Engler and Prantl's Na- 

 turliche Pflanzenfamilien) ; and publications of the Di- 

 vision of Vegetable Pathology of the U. S. Department 

 of Agriculture. 



10. Experimental Physiology. Five hours. Professor NEW- 

 COMBE. 



This course includes for each week two lectures, consider- 

 able reading of general and special treatises on plant 

 physiology, and from 8 to 10 hours of laboratory work. 

 During the laboratory work the students are under the 

 constant supervision of the instructor. They are assisted 

 and advised in making preparations and in setting up 

 apparatus. Typewritten laboratory guides are furnished 

 each student, the experiments in which are, some of 

 them, original, while others are selected from the prac-
