586 ANNUAL REPORT SMITHSONIAN INSTITUTION, 1921. 



in the earlier volumes, these beginning with an admirable address 

 in volume 1 by my old friend, Dr. J. M. Toner, now dead for many 

 years. On reading this address I find many suggestive statements, 

 suggestive in the light of later discoveries. But perhaps the most 

 interesting article in the volumes, from the historical point of view, 

 is the revolutionary paper read by Walter Reed in October, 1900, 

 modestly entitled "A Note on the Etiology of Yellow Fever." Lazear 

 had just died (September 25), and Reed, when calling upon me in 

 passing through Washington on his way to the meeting^ told me that 

 he was making his first announcement before this association on ac- 

 count of its great activity in matters relative to the dread disease. 



The list of investigators who have died for the public good in the 

 course of the investigations we have been considering is already 

 large. I have mentioned Lazear, Ricketts, McClintock, and McCray, 

 and have shown that the deaths of Reed and Carroll occurred most 

 prematurely shortly after their monumental discovery was an- 

 nounced As a fairly complete list of these martyrs of science is 

 given in another chapter of this volume*, they need not be repeated 

 here.
