Institute tiicrc, and in I') ID hcLOinc an instructor in pathoK)^y and 

 bactcriolos^y at Cornell. June 30, 1911, Dr. Coca had congratu- 

 lated Smith on three other publications and exclaimeil, " Who 

 would have looked for studies on Sarcoma and Bacillus Coli from 

 the Department of Agriculture. Please accept my very warm 

 thanks for these interesting and important works." Moreover, 

 R. Weil of the department of experimental medicine and of the 

 same laboratory and medical college planned, he wrote Smith, to 

 " undertake the inoculation of your plant tumor cultures into 

 various species of animals," and asked Smith for culture material 

 if Smith wished this-done. Other medical laboratories similarly 

 sent for culture materials. Also a number of prominent medical 

 doctors. 



Not only medical colleges and doctors of eminence sent 

 interesting letters, but also public health laboratories, biological 

 laboratories of private companies, and scientific research institutes 

 public and private the world over from Norway and Canada on 

 the north, Brazil and Argentina on the south in the western hemi- 

 sphere and the Union of South Africa and Mysore, India, in the 

 eastern hemisphere. M. A. Barber of the Bureau of Science of 

 the Philippine Islands reviewed the work before its Science Club, 

 and the university medical school. On September 28, 1912, the 

 British Aiedkal Journal "' recognized the work, not in complete 

 agreement with Smith's claims, but with full acknowledgment of 

 its value as " thoroughly good " research stimulating to other 

 workers to " enter upon this field of investigation." During 1912 

 William B. Brierley, lecturer on economic botany at the University 

 of Manchester, whose principal work and interest was the study 

 of plant diseases, wrote he considered it a privilege and pleasure 

 to come in contact, " however remote, with one to wdiom the 

 Science of Plant Pathology is so deeply indebted and for whose 

 Scientific work I and all botanists have the greatest respect and 

 admiration." " Those [papers and bulletins] dealing w^ith Crown 

 Gall and Human Cancer," Brierley wrote in his second letter of 

 1912, 



I found of such extreme interest, that I presented them before a meeting 

 of Botanical Teaching Staff and Researchers today. Dr. C. Powell White
