observation overrode Ms inclination to put 

 his knowledge into printed form. His pub- 

 lications bear no proper relation to bis work 

 and knowledge. 



H. L. Bruner, one of tbe assistants in my 

 time, grave and serious as a young man, 

 was assiduous and painstaking in bis work, 

 and immune to sea-sickness. J. Henry 

 Blake, who succeeded Emerton as artist, 

 and was in tbe laboratory for tbree or four 

 years, is anotber who bas built himself a 

 pleasant habitation in my memory. 



Among the young men who worked in 

 tbe laboratory on Little Harbor in 1882 

 and 1883 were also B. P. Koons, W. B. Saf- 

 ford, Peter Parker and Ralph S. Tarr. 

 Tarr was so much impressed with the accu- 

 racy of Vinal N. Edwards as a weather 

 forecaster that he declared that if Vinal 

 Edwards said it was not going to raiu in 

 the afternoon he would still believe him 

 even if his own senses told him that there 

 was a genuine downpour. 



A year or two later, Professor "W. Libbey 

 for at least a summer, and Professor W. B. 

 Scott, as an occasional visitor, brought new 

 ideas and methods, and Dr. McCloskie, too, 

 brought a breeze of enthusiasm with him 

 that was most refreshing. 



Among the numerous visitors to the lab- 

 oratory who tarried long enough to impress 

 their strong personality on us younger men 

 I recall most vividly and pleasantly Pro- 

 fessor Cope and Doctors Osier and S. Weir 

 Mitchell. 



It is not my purpose to extend these rem- 

 iniscences much beyond the days when Pro- 

 fessor Baird's presence was the most potent 

 influence in this community. I shall, how- 

 ever, insert a few observations on the sea- 

 son of 1889. 



Eeturning after a year's interval, I found 

 a complete change in the personnel, and but 

 little change in the spirit which pervaded 

 the laboratory. The laboratory was under 



the efficient directorship of Dr. H. V. Wil- 

 son. The laboratory workers still had their 

 mess ia the residence building, where I 

 greatly missed the benign presence of Pro- 

 fessor Baird. 



There was here, however, that summer, a 

 man of quiet and unobtrusive manner, who, 

 as it seems to me, had elements of real 

 greatness in his nature in higher degree 

 than any one whom it has been my fortune 

 to know. That was Professor W. K. Brooks. 



It was an interesting lot of young men 

 that I found in the laboratory of the U. S. 

 Pish Commission in 1889. There was E. A. 

 Andrews, then and still of Johns Hopkins 

 University; H. V. Wilson; P. H. Herrick; 

 E. R. Boyer, C. B. Davenport, and W. M. 

 Woodworth, post-graduate students of Har- 

 vard ; M. C. Greenman, a post-graduate stu- 

 dent of the University of Pennsylvania; 

 R. P. Bigelow, C. P. Hodge, T. H. Mor- 

 gan, and Sbo Wata^e, post-graduates of 

 Johns Hopkins. Of this group, Hodge, who 

 has recently molted the effete east, has 

 written of dynamic biology. I think it can 

 be said with truth that he and the others of 

 this little group, after the quarter of a cen- 

 tury that intervenes, are to be reckoned as 

 among the potent dynamic agencies in the 

 biological science of this generation. 



The Marine Biological Laboratory had 

 been opened the previous summer. Dr. 

 Whitman bad already inaugurated the cus- 

 tom of having evening lectures. They were 

 held in the one laboratory building ia the 

 room, I think, in which the invertebrate 

 course is now conducted. 



In 1889 cross-breezes were rufSing the 

 calm of the biological atmosphere. There 

 were some in the laboratory who stoutly de- 

 nied that the surroundings did or could 

 have any manner of influence on the germ 

 cells. There was no god in animated na- 

 ture but heredity and Weismann was his 

 prophet. In those days also the neo-La-
