438 First European Journey 



nected with pathological growth in plant life which might throw some 

 light on the many pathological conditions which we find in animal life. 

 While with Dr. [Walter Bradford Cannon, professor of physiology of 

 Harvard Medical School] I mentioned this subject to him and he imme- 

 diately referred me to you. I shall read the reprints with great pleasure 

 and hope that I may find something in them which I can apply to my work. 



If at any time I can be of service to you in supplying you with path- 

 ological material, I shall be only too glad to send you what I can. Our 

 material is very extensive and more than we can really handle, and we will 

 be very glad to turn anything over to you which might be of service. ■ 



If I should find any connection between the new growths in plant life 

 and animal life I shall immediately communicate with you. 



On March 30, a little more than a month after Dr. MacCarty 

 had written, Dr. Gaylord, now director of the Cancer Laboratory 

 of the New York State Department of Health, sent Smith some 

 references to literature on tumor transplantation, accelerated growth 

 in mouse tumors, and other topics. A second paragraph of his 

 letter extended a cordial and significant invitation: 



I find that I shall be in Boston for the meeting. We will meet on April 

 8th and if you can find it possible to be present at the meeting and present 

 your material it would give us the very greatest pleasure. As secretary of 

 the society, I extend to you an invitation to present your material at that 

 meeting. I expect to be in Washington on Wednesday or Thursday and 

 will try to find time to discuss the matter further with you. 



During 1909-1910 Dr. Gaylord served as president of the 

 American Association for Cancer Research. Such interest was 

 aroused at the Boston meeting by Smith's lantern-slide illustrated 

 address that he was invited the next year to appear before the 

 Association at its spring meeting in Washington. At this time 

 Smith exhibited specimens of crown gall. Still again, and for the 

 third time, he addressed the Association at its Buffalo meeting, 

 April 13, 1911, on " Crown-Gall and Sarcoma," ^'^ in which he 

 stressed likenesses, developmentdly, between crown gall, a plant 

 cancer, and certain malignant neoplasms in man. He called atten- 

 tion to " the method of action of the parasite on the cells of the

 before the American Association for Cancer Research, an abstract of which was
