ZOOLOGY. 
1. The Natural History of Vertebrate Animals, with 
special reference to behavior and evolution. ‘The fishes, 
amphibians, reptiles, birds and mammals of the region 
will be collected and identified and as far as possible their 
habits will be studied in the field and laboratory. Stu- 
dents will thus learn to recognize the native vertebrates 
at sight. In the field special attention will be given to 
methods of work. The exact methods of the laboratory, 
not hitherto commonly used in the field, will be applied 
to the observation of animal habits and to the making of 
field records, both written and pictorial. Photography 
will be used whenever possible both for terrestrial and 
aquatic forms. The records made in the field will form 
the basis of written reports, reading will be required and 
conferences will be held for the discussion of the rela- 
tion of the observations to the general problems of ani- 
mal 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 modern 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 Anmals.— 
The protozoans, sponges, coelenterates, rotifers, bryo- 
zoans, worms, crustaceans, spiders, myriapods, insects and 
molluscs of the region wll be studied. Both aquatic and — 
terrestrial invertebrate animals will be collected and iden- 
tified, so that students will gain a general familiarity 
with them and learn to recognize the common species at 
sight. Especial 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, turbidimiter and centrifuge. The field work will 
be supplemented by a more detailed examination of ant-
