I. PREFATORY NOTE TO THE SHALER :\IEMORIAL 



SERIES.

 Professor of Geology at Harvard University, during his long career 

 as naturalist and teacher, both by his writings and his teaching, 

 displayed a very wide interest in the various aspects of the earth's 

 sciences. When in commemoration of his long services to the Uni- 

 versity a group of over seven hundred of its alumni raised an endow- 

 ment of more than $30,000. for the purpose of maintaining and 

 publishing the results of investigations suitable to his memory, the 

 Division of Geology, to which this gift was entrusted, found itself 

 provided with a fund for the advancement of knowledge in the entire 

 field of its scope. 



The following are the terms governing the use of the Shaler Me- 

 morial Fund (see the letter of gift in the Annual Report of the Curator 

 of the Museum of Comparative Zoology for 1906-07, Cambridge, 

 1908, p. 19-20). 



"The researches here contemplated are to be undertaken by persons nomi-

 Corporation, whether officers or students of Harvard University or not.
