 Oekologische Pflanzengeographie ; Pound and Clements, 

 Phytogeography of Nebraska; Engler and Prantl, Nat- 

 iirliche Pflanzenfamilien ; and ecological papers in recent 

 periodicals. 



16. Teachers' Conference and Field Club. One hour. In this 



course the time will be occupied during the first half of 

 the semester with conferences and reports on lists of 

 books, apparatus, and material for high school labora- 

 tories, and practical methods; during the second half of 

 the semester, excursions will be made under the guidance 

 of different members of the corps of instructors, for the 

 purpose of learning methods of collecting and preserving 

 material and conducting field observations. Professor

17. Investigations in Physiology. Professor NEWCOMBE. Occa- 



sionally an undergraduate in his senior year is allowed to 

 elect work in course under this heading. Such may elect 

 3 hours, 5 hours, 8 hours or 10 hours. 



The laboratory labors under the disadvantage of not occu- 

 pying a building constructed for the purpose, but is, nev- 

 ertheless, well equipped for work in general physiology 

 and especially well equipped for certain lines of physiolog- 

 ical work. There are incubators and sterilizers and glass- 

 ware sufficient for work in plant diseases ; there are bal- 

 ances, chemicals, glassware, etc., suitable for work in 

 chemical biology ; there are large aquaria and other facil- 

 ities for the study of the biology of water plants, and 

 nearby ponds, lakes and rivers for out-door work; there 

 is electrical apparatus for studying the relations of plants 

 to electricity ; there are turning machines klinostats and 

 centrifuges for studying the relation of organisms to 

 gravitation and light. Electric and water motors supply 

 power for turning trains of these machines, the present 

 capacity being ten machines revolving in horizontal, ver-
