The world's senior plant bacteriologist, Thomas Jonathan 

 Burrill, reading the second volume of Smith's Bacteria in Relation 

 to Plant Disease, addressed two letters to Smith within the month 

 of February 1912. "I cannot express in words my appreciation 

 of the way you have done this work — let me say the admiration 

 I have for the notable accomplishment," he said on February 17. 

 " I know nothing anywhere like it in botanical literature that can 

 be called its equal. We will wait now with great expectations 

 for what is further to appear." And on February 9 he had written, 

 "' Permit me to say that I am very greatly interested in your revela- 

 tions concerning the similarity of crown gall and cancer in the 

 animal body." 



Dr. William Osier found the second volume of Bacteria in 

 Relation to Plant Diseases of " the greatest interest," so much so 

 that he passed it on to a very close and " great friend " in the 

 Agricultural Department of Oxford. "What an extraordinary 

 amount of work it represents," he uttered with characteristic spon- 

 taneity, "" and in such a new and encouraging field. If you ever 

 come over here, let us see you." 



Dr. Adami of McGill University on May 22, 1912, sent Smith, 

 " Heartiest congratulations over your continued good work with 

 the Crown-gall organism." Reading Smith's The Structure and 

 Development of Croivn Gall, he rejoined, " It is a triumph to be 

 able to demonstrate it within the cells." 



Dr. Edwin O. Jordan, professor of bacteriology at the University 

 of Chicago, in 1912 rated the whole work in crown gall as " one 

 of the most important and fundamental contributions of recent 

 years, and," he told Smith, " I heartily congratulate you on your 

 really splendid success and on the far-reaching results that I 

 think will flow from these discoveries." 



" Please accept my most sincere thanks for this valuable con- 

 tribution to the etiology of malignant tumors — Bulletin No. 255 — 

 which I have just received," wrote A. F. Coca of the department 

 of experimental pathology, Loomis Laboratory, of Cornell Uni- 

 versity Medical College on July 8, 1912. " The plates are wonder- 

 ful. It is a handsome piece of work. I heartily congratulate you." 

 Coca had obtained his degree of doctor of medicine from the Uni- 

 versity of Pennsylvania, had studied at the University of Heidel- 

 berg, Germany, spending two of the years 1905-1909 at the Cancer
