and function of the various cell-plastids, of the nucleus, 

 and of the cytoplasm. As nuclear and cell division are 

 studied, the theories of heredity are discussed. Some 

 time is given to the practical study of enzymes. The 

 last three or four weeks of the semester are occupied 

 with the study of the development of the mature plant 

 from the embryo, the development of members, general 

 anatomy and the functions of tissues. 

 Throughout the course, the student makes his own prepa- 

 rations, learning thereby the modern technique of em- 

 bedding, cutting with the microtome, staining and 

 mounting. 



II. Experimental Physiology. Special Problems. Two or mom 



hours. Professor NEWCOMBE. 



The work of this course requires some degree of inde- 

 pendence on the part of the student. It is to be pre- 

 ceded by Course 10, Special problems are assigned for 

 research, these being intended to exercise and develop 

 the ability of the student for severer original investiga- 

 tion. 



13. Habits and Distribution of Plants. A review of recent 

 literature on the biological relations of plants, accom- 

 panied by field studies. Two or more hours. Professor 

 SPALDING. 



In this course the habits and adaptations of plants in their 

 native habitats will be studied in the field. At present 

 the societies of aquatic and amphibious plants are receiv- 

 ing special attention, and forms that are adapting them- 

 selves to changes of water level and other varying fac- 

 tors are under investigation. In general outline the 

 course corresponds to the ground covered by Schimper, 

 Pflanzengeographie auf Physiologischer Grundlage. Re- 

 views will be given of such ecological literature as Mac- 

 Millan, Distribution o'f Plants at Lake of the Woods; 

 Pound and Clements, Phytogeography of Nebraska; and 

 recent papers of Cowles, Kearney, Bray, and others. 



15. Experimental Morphology. Evolution of form and habit 

 in adaptation to environment. Two or more hours. Dr. 

 BURNS.
