microscopist and a photomicrographcr of note, he had distin- 

 guished himscll as a preparer of microscopic specimens, "the 

 best," Dr. BiUint;s had said, " in this country." ^' Smith surely had 

 used the splendid hbrary of the Museum and perhaps before this 

 time had visited the microscopical room located next to the 

 Museum on the third iloor of the building completed on February 

 1?, 1888. Pathologists occasionally gathered at meetings of, or 

 held in, the Museum. On at least one occasion Dr. W. H. Welch 

 of Johns Hopkins had attended. Men of the Bureau of Animal 

 Industry were interested in at least one of his investigations. A 

 preliminary account of his studies on hog cholera was published 

 in the first Johns Hopkins Bulletin of December 1889."* 



In 1889 Smith may have visited, among other laboratories, those 

 of Dr. Prudden and Dr. Hermann Biggs in New York. Dr. Biggs 

 was a friend of Theobald Smith, and from him Smith may have 

 obtained his list of laboratories which included the Hoagland 

 Laboratory in Brooklyn where Dr. B. Meade Bolton was in charge 

 and where Dr. Sternberg in 1888 had given a lecture on the 

 " Bacteria." ^^ In his "Record Book," Smith wrote at some time: 

 "The first filtering of meat infusion, agar, etc., may be through 

 cotton. The results are very satisfactory. This methed saves much 

 time and is in constant use in Dr. Prudden's laboratory." He, 

 furthermore, in April 1891, wrote Galloway of a " very readable 

 article on bacteria " by Prudden in Harpers Monthly Alagazine.^^ 



Dr. Bolton in 1887 had been among those seventeen physicians 

 who had taken work as students or special investigators in 

 Welch's laboratory at Johns Hopkins. Councilman was then 

 Welch's associate and, among others enrolled, were such doctors 

 of future distinction as Franklin P. Mall, fellow, Alexander C. 

 Abbott, W. D. Booker, W. S. Halsted, C. A. Herter, and Stern- 

 berg."' That year Bolton assisted Welch in the bacteriological 

 instruction which included " methods of isolatmg and of culti- 

 vating micro-organisms and the morphological and the biological
