The University of Chicago Science Series, 
established by the Trustees of the University, 
owes its origin to a feeling that there should be 
a medium of publication occupying a position 
between the technical journals with their short 
articles and the elaborate treatises which 
attempt to cover several or all aspects of a wide 
field. The volumes of the series will differ 
from the discussions generally appearing in 
technical journals in that they will present the 
complete results of an experiment or series of 
investigations which previously have appeared 
only in scattered articles, if published at all. 
On the other hand, they will differ from detailed 
treatises by confining themselves to specific 
problems of current interest, and in presenting 
the subject in as summary a manner and with 
as little technical detail as is consistent with 
sound method.
