PREFACE. 



Although the Katmai Expeditions have been initiated and", 

 financed exclusively by the National Geographic Society, the 

 personnel of the expeditions has been made up, from the first, 

 largely of Ohio State men, and the Scientific Results have to a 

 large extent been worked up in the laboratories of the University. 

 It seems appropriate, therefore, that these results should be 

 issued among the contributions from the Ohio State University. 



These papers were first published in the Ohio Journal of 

 Science. They are here reprinted without change other than 

 the correction of a few typographical errors which were serious 

 enough to be misleading. It is expected to continue the 

 publication by issuing further papers as they are prepared. 

 When the series is complete it is planned to revise them and to- 

 bring them together in book form as a single publication by 

 the National Geographic Society.
