bis later accomplishments at the Harvard Medical College and at the 

 Rockefeller Institution branch at Princeton have placed his name very 

 high in the annals of medical research. 



I have had the pleasure of knowing W. G. MacCallum who in 1889 

 published a paper in which the true function of the flagella in a cer- 

 tain stage of certain malarial organisms was first shown. 



Years later I became well acquainted with Walter Reed, James 

 Carroll, and Jesse W. Lazear. They came to the entomological offices 

 in the Department of Agriculture to study mosquitoes before they 

 went to Cuba where their immortal discoveries were made. During 

 the progress of the Cuban work Walter Reed wrote me frequently 

 for information about mosquito questions. Henry R. Carter, whose 

 investigations had a strong bearing on the results reached by the 

 Army Commission later became a friend and a frequent visitor to 

 the Bureau of Entomology. Dr. J. H. White, of the United States 

 Public Health Service, who had charge of the work in New Orleans 

 during the epidemic of 1905 and who succeeded in stifling the epi- 

 demic in a most dramatic and spectacular manner by his intensive 

 work against the yellow fever mosquito, was then well known to me. 

 I visited New Orleans toward the close of his work, and since that 

 time we have often talked over this and similar matters. The well 

 known parasitologists. Dr. C. W. Stiles and Dr. PI. B. Ward, are old 

 and warm friends. Prof. R. W. Doane of Stanford University, who 

 wrote the earliest American book on insects and disease, is also an old 

 and valued friend. D. L. Van Dine, who began the first anti-mosquito 

 work in Honolulu and who has since carried on some extremely 

 fine malaria investigations for the Bureau of Entomology in Louisi- 

 ana, has been a friend and associate for many years. The late Gen- 

 eral Gorgas and his right-hand sanitary engineer J. A. LePrince 

 came to the Bureau of Entomology before they left for Panama, and 

 corresponded with us for many years. One of the last letters that Gen- 

 eral Gorgas wrote before his lamented death in London was addressed 

 to me in answer to one I had written to him inquiring as to the truth 

 of the statement that he endorsed Doctor Campbell's ideas concerning 

 bat roosts and malaria. His reply was to the effect that he did not 

 endorse them. In his successful clean-up of Habana and his later 

 work in Panama the remedial measures against mosquitoes published 

 by the United States Bureau of Entomology in 1898 were used as a 

 basis with later elaborations and details suggested by the fertile brain 

 of Mr. LePrince. This assistance is acknowledged by Mr. LePrince 

 in the book that he published later, in collaboration with Dr. A. J. 

 Orenstein, entitled "Mosquito Control in Panama" (New York,
