X FOREWORD 



Dr. William T. James, are reported by him in the present 

 monograph. Dr. 0. D. Anderson, who studied the role of the 

 endocrines in the production of behavioral types, contributes 

 the last chapter. 



During the last two years of his life, Doctor Stockard spent 

 much of his time organizing and digesting the large mass 

 of data which had been slowly accumulating. In the winter 

 of 1938 he began the redaction of the present monograph on 

 which he worked continuously during the summer of that 

 same year at his home in Woods Hole. At the time of his 

 death in the following spring, the manuscript was taken 

 over by a committee formed of Drs. Alan Gregg, Herbert S. 

 Gasser, Joseph C. Hinsey, A. LeRoy Johnson, Oscar D. 

 Anderson, William T. James, Jose F. Nonidez, and William 

 S. Ladd, Chairman. 



A reading of the manuscript by the committee disclosed 

 the fact that it was in a form finished enough for publication. 

 Undoubtedly, Doctor Stockard would have made changes in 

 the manuscript after a few more readings. The policy of the 

 committee, however, has been to do a minimum of editing, 

 and the style and phraseology have been left untouched. It 

 is a matter of regret that the chapter on the histology of 

 the endocrines was left unfinished ; only introductory remarks 

 on the cross of the St. Bernard and great Dane were found. 

 It is still more regrettable that Doctor Stockard was unable 

 to offer a discussion of the relation of the endocrines to type, 

 probably the most important chapter of the whole monograph. 



For the preparation of the manuscript and illustrations 

 the committee is much indebted to Mrs. Ellen P. Schoenborn, 

 who also undertook the tedious task of reading the proofs.

For the Committee 



By action of the Trustees of Cornell University, the Stockard collection of 

 material on genetics at Cornell University Medical College has been presented 

 to The Wistar Institute of Anatomy and Biology at Philadelphia. After the 

 material has been assembled and placed on exhibition it will be made available 

 at The Wistar Institute for continued study by anyone interested in the subject.
