A Biographical Stretch xxiii 



coming each day to assist her husband, first in the organization 

 and classification o£ his Hbrary, notes, and collections, and later, 

 having perfected herself in microtechnique, in the researches 

 which he had in progress. During the next fifteen years, Mr. 

 and Mrs. Setchell undertook together a series of extended scien- 

 tific expeditions, principally in the Pacific area. They both en- 

 joyed travel, and in this as in every other aspect of their life 

 together, they found nothing but experiences of mutual interest. 

 Mrs. Setchell's unselfishness and serenity of spirit were never 

 more apparent than during the more than two years of disabil- 

 ity which preceded her final illness, and her obvious desire that 

 her condition should as little as possible interfere with the prog- 

 ress of her husband's work was realized. 



In this brief biographical statement no effort has been made 

 to recite the total of Professor Setchell's scientific concerns or 

 achievements. Nevertheless, by illustration and comment the 

 breadth of his biological horizon and the importance of his 

 research contributions have, hopefully, been exhibited. An obvi- 

 ous effort has been made throughout to indicate the character 

 of the associations and influences which have operated in init- 

 iating and directing his scientific pursuits. Given those qualities 

 of mind which he possesses, certain, at least, of the diverse influ- 

 ences which are sure to approach the biologist may be produc- 

 tive of the broader, more significant, and more useful type of 

 scientific career and should, therefore, not be thrust aside with- 

 out due consideration. If a somewhat personal tone appears as 

 characteristic of some parts of this effort to present a sketch of 

 a distinguished man, it must be referred to the writer's intimate 

 acquaintance with him for more than a quarter-century.

 of which Professor Setchell is at present a member, the National
