have one common feature; three lectures or readings are given 
each week to the discussion of the history of zoology and paleon- 
tology, with special reference to modern opinions concerning the 
relations of animals. An effort is made to acquaint the students 
with the character of the greater works in the science, by giving 
them constant opportunities for consulting them in their studies 
and by showing them the methods of the masters in the several 
departments. Besides this each student is required to pursue some 
special line of work. In the choice of subject the largest liberty 
is allowed, but the student is, however, recommended during 4 
half year to study advanced microscopy; in this work the aid of 
an instructor is given for four hours a week. In this four months 
he should acquire a sufficient knowledge of the practical manage 
ment of the instrument in all ordinary investigations. The labo- 
ratory is well supplied with instruments of instruction in this 
branch of work. j 
Besides the course in the history of the science, the student 
who takes the elective in palæontology is required to traverse the 
ground covered in that part of “ Dana’s Manual” which is entitled 
historical geology, acquainting himself in a practical way with the 
most important characteristic fossils of the several periods. 
The greatest value in this work is set upon the keeping of fall 
and accurate note books in both the last described courses. Te 
rank of the student turns upon the condition of his note books, 
as much as upon the quarterly examinations which he is required 
to pass. 
Those students who desire to contend for honors at the gr adua- 
tion in zoology or in paleontology, are required to have taken e 
sides their junior election in natural history, one election in phys : 
eal science, and at least three natural history elections in the jas 
year, in all of which they must have attained excellence. = 
are, moreover, required to write an acceptable thesis which ”
