Announcement of the 



COURSES FOR UNDERGRADUATES AND GRADUATES 



It is not the purpose of the Station to duplicate the work offered 

 at the University, but to provide facilities for field work of a sort 

 that cannot be so well carried on under urban conditions or with 

 the restrictions imposed by a university schedule. Instruction is 

 limited to the courses announced, but qualified students may arrange 

 to follow other lines by electing the special courses. A student may- 

 give his entire time to either botany or zoology or may divide it 

 between these subjects, but no student, is permitted to take work 

 for more than eight hours University credit. Each of the four-hour 

 courses is planned to occupy one-half the students time, the two- 

 hour courses, one-quarter ; the special courses may take the whole 

 or any part of the time, in all courses at least half the time is spent 

 in the field. The work of research students will be arranged in 

 accordance with the nature of the problem selected. 



Each course occupies the entire working day assigned to it, and 

 consists of field or laboratory work, supplemented in every case by- 

 lectures, recitations, or conferences, and by assigned reading and 

 preparation of reports. 



Graduate students, when regularly matriculated in the Univer- 

 sity and properly registered with the Dean of the Graduate School,. 

 may carry on work at. the Station which will count toward an ad- 

 vanced degree. 



For full information concerning the requirements for advanced 

 degrees, address the Dean of the Graduate School, Ann Arbor, Mich- 

 igan. 



Zoology 



ioi. The Natural History of Vertebrate Animals. — The course 

 deals chiefly with fishes, amphibians, and reptiles, not with birds 

 (see Course 107), and only incidentally with mammals. As far as 

 possible representatives of all forms of fishes, amphibians and rep- 

 tiles occurring in the region are collected, identified and studied in 

 both field and laboratory. Particular attention is given to the ecology 

 of the several species and correlated studies of the food, habitats, 

 enemies and interrelations of the various species are made. The 

 general problems of evolution, distribution and taxonomy are con- 

 sidered as opportunity offers. Although most of the work is given in 

 the field, attention to precise methods of observation and to the cor- 

 rect use of data is required. 



Thursday. Tzvo hours credit. Assistant Professor En is. 



Prerequisite : Elementary collegiate zoology. 



This course gives one hour credit to graduate students. Such 

 students, wishing full credit, must perform extra work, and will reg- 

 ister for Course iota.
