from one tumour will nc-utralize the viruses from other types of tumour; 

 which indicates a common antigenic clement. 



Chemical, physical, or parasitic causes have usually been 

 described bv Dr. Gve as " remote or adjuvant. " But these " lead 

 to cancer and the intracellular continuing cause. This continuing 

 cause is related to the pathological nature of cancer and is, in the 

 sense in which we say that the tubercle bacillus is the cause of 

 tuberculosis, the cause of cancer." 



In September 1926 Dr. Smith attended the International Sym- 

 posium on Cancer held at Lake Mohonk, New York, Mountain 

 House under t4ie auspices of the American Society for the Control 

 of Cancer. He was not a member of this organization and not on 

 tlie program of speakers. But, on the morning of September 23, 

 his extemporaneous remarks "' on the question of parasitism in 

 cancer " stirred up " a lively discussion." '•"' With him he had his 

 crown gall photographs, and, in his room, he showed them to 

 many important men of the conference: Dr. Henri Hartmann and 

 Dr. Gustav Roussy of France, the first of whom he had met while 

 in Paris; Dr. Raffaele Bastianelli, associate professor of surgery at 

 the University of Rome and vice president of the Italian League 

 for the Control of Cancer; Sir John Bland-Sutton, president of the 

 Royal College of Surgeons of England; and many other European 

 and American scientists. At the conference Dr. Blumenthal told 

 him of the Kaufmann work at Koch's Institute. On Pelargonium 

 and sunflowers five large tumors had been produced with bacteria 

 (resembling Bacterium tumejaciens) from mouse cancer (Ehrlich 

 strain) . He told Smith also of other workers who claimed to have 

 obtained one plant tumor on a Pelargonium with " a yellow 

 schizomycete growing only at 30°." ^"' Dr. Blumenthal was later 

 Smith's guest in Washington and spent a morning in his labora- 

 tory.^^*^ As the concluding event of the symposium, the foreign 

 guests were honored with an elaborate dinner at the Hotel Astor 

 in New York City. Dr. Smith attended this occasion, and also a 

 cancer research program held at Johns Hopkins Hospital on 

 September 27. He returned the next day to his laboratory and set 

 out his crown gall material for any guests who might visit his
