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 life.
