drawings and water color paintings of algae," Bornet's library, 

 Thuret's herbarium, and " photos or engravings of many promin- 

 ent algologists, including Dr. Farlow." He visited the laboratory 

 of Madame Lemoine, " an expert on calcareous algae." ®^ He 

 spent another day at the Pasteur Institute with Dr. Besredka and 

 Dr. Weinberg.^^ When calling on Dr. Itchikawa in Dr. Roussy's 

 laboratory again, he became acquainted with Dr. A. Kotzareff who 

 had discovered " an interesting test for cancer." " His mare 

 complete estimate of this was later told to Dr. Sofia A. Nordhoff- 

 Jung of Washington:

Dr. Kotzareff has found that if a few millicuries of radium emanations 

 are added to auto serum and injected intravenously into cancer-bearing 

 animals, they are not injured by it and the emanations are absorbed by the 

 tumors which are killed. Undiscovered internal tumors may also be diag- 

 nosed in this way by exposing a photographic dry plate over the suspected 

 spot. The only other tissues of the animal body capable of absorbing the 

 radium are embryonic tissues. The method has been tried in a few cases 

 of human cancer with apparently favorable results, but much remains to 

 be done. . . . His method of attack on cancer seems to me at least very 

 hopeful and every method of approach offering any least likelihood of 

 success ought to be tried out thoroughly. It is at least very suggestive that 

 Dr. Blair Bell's treatment in Liverpool, now attracting so much attention, 

 acts in the same selective way, the lead salts killing the tumor cells more 

 readily than they do the normal cells. It is interesting also that Dr. Blair 

 Bell was induced to try lead salts in cancer by observing that in abortion 

 in rabbits, induced by means of lead, it is the actively-growing chorionic 

 cells that are killed. ^^ 



On the way from Paris to Berlin, Dr. and Mrs. Smith stopped 

 for a few days at Strasbourg where Dr. Amedee Borrel was in 

 charge of the Pasteur Museum and the Institute for Bacteriology 

 and Hygiene, one of the best in France. Before leaving America, 

 he had written Borrel who told Smith to " Come over at once," 

 and so they went immediately to the Musee Pasteur where they 

 were shown through " the magnificent laboratory building " and 

 the museum. Research work was going on in tuberculosis, cancer, 

 syphilis, vaccine virus, and " all sorts of human and animal
