ZOOLOGY. 
1. Ihe Natural History of Vertebrate Animals, with 
special reference to behawor and evolution. ‘The course 
will deal chiefly with fishes, amphibians, and mammals, 
but not with birds (see Course 3), and only incidentally 
with reptiles. As far as possible the forms occurring in 
the region will be collected and identified and their habits 
studied in the field and laboratory. Students will thus 
learn to recognize many of the native vertebrates at sight. 
In the field special attention will be given to methods of 
work. The exact methods of the laboratory, not hither- 
to commonly used in the field, will be applied to the ob- 
servation of animal habits and to the making of field rec- 
ords, both written and pictorial. The records made in 
the field will form the basis of written reports, reading will 
be required, and conferences will be held for the discus- 
sion of the relation of the observations to the general 
problems of animal behavior and evolution. 
The attempt will be made to give to teachers and 
others a certain measure of that intimacy with living 
animals out of doors that forms the charm of Thoreau 
and Burroughs. At the same time precise methods of 
observation, record, and interpretation will be utilized 
for scientific ends. ‘Two half days of field or laboratory 
work and one conference weekly. Two hours credit.

2. The Natural History of Invertebrate Ammals.— 
The protozoans, sponges, coelenterates, rotifers, bryo- 
zoans, worms, crustaceans, and molluscs of the region 
will be studied. Both aquatic and terrestial inverte- 
brate animals will be collected and identified, so that 
students will gain a general familiarity with them and 
learn to recognize the common species at sight. Es- 
pecial attention will be given to exact methods of field 
observations and to the making of field records. The 
principles of fresh water biology will be studied, 
and practice will be given in the use of such apparatus 
as plankton pumps and nets, the thermophone, thermo- 
meter and turbidimeter. The field work will be supple- 
mented by a more detailed examination of animals in the
