course in Palaeontology is no longer open to undergraduates, 

 except in cases where they have received a complete preparation 

 for it. The course itself now extends over two years, — the first 

 year including systematic Palaeontology ; the second. Historical 

 Geology. A post-graduate course in advanced field-work has 

 also been added to the scheme of studies ; the object being 

 to train students in the methods of making geological surveys. 

 The summer school will also be divided into a two-years term ; 

 tlie first year for beginners, the second year for persons of some 

 training. The first or elementary course will be taught during 

 the next summer in Cambridge, and in the Catskill region of 

 New York ; the second-year or advanced course will be taught, 

 in connection with the work of the Kentucky Geological Survey, 

 in Eastern Kentucky and the neighboring States. Mr. Davis 

 will have immediate charge of the first-named course ; the other 

 will be under my own supervision. 



A considerable part of the time of the instructors in these 

 departments has been given to the maintenance of the efficiency 

 of the Harvard Natural History Society, which is now a valuable 

 aid to the schemes of instruction given at this Museum. This 

 society has provided fortnightly meetings devoted to subjects 

 connected with general Natural History, and also a section with 

 meetings once a week, devoted to Geology and Palaeontology. 

 The societ}^ also maintains a system of prizes, to be given to 

 students in high-schools and academies, for work done on 

 designated scientific subjects. It furthermore supplies a course 

 of popular lectures on scientific subjects, open to the public of 

 this vicinity. Eight lectures were given in this course during 

 the past year, with an average attendance of one thousand 

 persons.
