558 Crown Gall-Animal Cancer Analogy 



H. Stevens. After two more days of study, he went on to Ann 

 Arbor and there found more cancer slide materials. Dr. Warthin, 

 he found on June 22, "' has thousands of cancer slides and it 

 would pay me to come here for two months to study them." Dr.. 

 Warthin disagreed with him that " cancer grows by apposition." 

 But when at Chicago he became acquainted with Dr. H. Gideon 

 Wells, formerly dean of medical work at the University of Chicago 

 and then director of medical research at the Otho A. Sprague 

 Memorial Institute, he found a medical scientist in partial agree- 

 ment with him, at least. " Wells," he wrote in his diary, " says 

 he thinks cancer of the liver grows by apposition from his own 

 observation on primary liver tumors. He gave me very helpful 

 references to half a dozen papers. He says all the pathologists 

 who have worked on pr[imary] liver tumors are agreed on this." 

 At Chicago, Smith first called on Professor E. O. Jordan. Wells, 

 he said, " who is a delightful man to meet, studied under [Ludvig} 

 Hektoen, and Jordan at Mass[achusetts} Tech. under Sedgwick 

 about whom we talked. He studied under Duclaux and is pleased 

 with the Pasteur book. He says D[uclaux] was a very genial man." 



Smith spent the next several days reading in the John Crerar 

 Library on primary carcinoma of the liver. On June 29 he happily 

 wrote in his diary: "" I have found very interesting confirmation 

 of my views, and have read about a dozen papers in English and 

 German and abstracted them. I have now the best part of the 

 recent literature and am ready to see Dr. MacCallum's slides." 

 At this library he renewed his acquaintance with J. Christian Bay, 

 who was then manager of the medical part and who during many 

 recent years has since been librarian there. In 1948 Dr. Bay, in 

 an article in Science ^^ on " Some vital books in science: 1848- 

 1947," characterized Dr. Smith's three volume work. Bacteria in 

 Relation to Plant Diseases, as "a peer in its field." 



While in Chicago, Smith called also on Miss Maude Slye, whose 

 researches in cancer (especially on heredity) he alluded to appre- 

 ciatively in addresses several times and whose work on breeding 

 races of mice formed part of not only his diary account of his 

 visit to her laboratory but also of the discussion of his address 

 that year on " Twentieth Century Advances in Cancer Research." 



Cleveland was the final destination of Dr. and Mrs. Smith's
