I. PREFATORY NOTE TO THE SHALER MEMORIAL 
SERIES. 
THE late Dean Shaler, at first Professor of Palaeontology and later 
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 Zodlogy for 1906-07, Cambridge, 
1908, p. 19-20). 
‘“‘The researches here contemplated are to be undertaken by persons nomi- 
nated by the Committee of the Division of Geology and appointed by the 
Corporation, whether officers or students of Harvard University or not. 
The subject and the locality or field of research are to be approved by the
