to its meetings. Many of his papers, since published, were read 
for the first time in its sessions. In addition to these more 
formal contributions not less important though less pretentious 
were the many brief notes which he contributed under the head 
of personal observations. Never did a meeting pass at which 
he was present without his reporting some new and interesting 
discoveries he had made during the month. These short obser¬ 
vations reveal a trait in his character which is becoming all too 
rare in the younger biologists, namely, his love of nature and 
his passion for study and collection in the field. In all of his 
forty years of collecting and close study of nature, he never lost 
in the slightest degree the enthusiasm of the youth making his 
first discoveries in science. From first to last he maintained 
unabated his great interest in the commonest things. At all 
times he enjoyed with the greatest intensity every observation 
made by his students, even if it was well known to him. Because 
of this he was one of the most stimulating persons any young 
man could have had to work under. Those who knew him in 
the field can never forget the keen, enjoyment of field trips with 
him nor the profit derived from them. 
As members of the Biological Club, many of us only begin¬ 
ning our scientific careers, we would recognize the inestimable 
value of such an impelling interest in our work and set it up as a 
mark for our own ideals, knowing full well that though few of us 
can hope to attain such intensity of enthusiasm as he reached, 
yet our success in large measure depends on our ability to main¬ 
tain as Dr. Kellerman did, the enthusiasm of youth through 
the years of mature fife.
