COMPARATIVE ZOOLOGY. [Jan. 



special aims are to train students in methods of presenting 

 their researches, and to secure their attention to all the note- 

 worthy contributions on natural science. To accomplish this 

 latter purpose, arrangements have been made with the special 

 students of various subjects to bring the contributions in their 

 several departments before the society for criticism and 

 discussion. 



The next session of the summer School of Geology will 

 begin at the Museum in the first week of July, 1877. After 

 about three weeks' work on the collections and in the neigh- 

 boring geological fields, the work will be continued in the 

 form of an excursion through the Connecticut Valley, the 

 Berkshire Hills, and the Scoharie Valley in New York. At 

 the close of the regular term of the school, the work will be 

 extended along the line of the railway to Louisville, Ken- 

 tucky, and will close with a few weeks' study in the cavern 

 district of Kentucky.
