laboratory work, living an exceedingly simple life with almost no 
exercise beyond that had in his daily trips to and from his office. His 
friends often marveled at his being able to maintain himself in work- 
ing condition under this routine, particularly when it was known that 
he was keeping persistently at his task of editing and writing, not only 
during office hours but evenings and Sundays, taking little or no recrea- 
tion and pursuing this course year after year. Even then the extraor- 
dinary amount of his scientific output was made possible only by his 
ability to prepare his manuscript practically ready for publication in 
the first draft, the years of training in writing reviews and doing other 
editorial work undoubtedly having developed this most enviable 
facility. 
For many years Doctor Allen’s career served as a great stimulus to 
young naturalists throughout the country. His clearness of insight and 
mental powers were backed with a strong will, which quickly impressed 
all who came in close contact with him. Among American scientific 
men few have been held in such general esteem and have been able to 
so influence their contemporaries and the development of the sciences 
in which they worked. His loss will long be felt not only among those 
who had the privilege of knowing him personally but by many workers 
who paid him the tribute of admiration and respect as a great scien- 
tific leader.
