618 Third European Journey 



other persons to be with him to examine my photographs but 

 more than fifty persons came, and I explained each one of the 128 

 photos to the crowd, as best I could, in their own tongue." Pro- 

 fessors and students from the university as well as the institute 

 were there, and several branches of research were represented, 

 biology, botany, internal medicine, and others. Hideo Komuro, a 

 Jap, became Smith's guide one day, Professor Charles Killian, 

 botanist, another day, when either Dr. Borrel or Dr. Masson could 

 not be with him. Smith was especially pleased to find a bio- 

 physicist [Professor Vies?] "doing a great deal of work on 

 normal and diseased tissues, using the potentiometer." ''' He 

 wished that he might accept more of the invitations offered him. 

 A tea " with half a dozen other research men " present, and 

 another tea " with three research women present " were enjoyable. 

 The great hospital of 2,500 beds in connection with the medical 

 school and the institute, where annually a thousand operations 

 were performed, provided Professor Masson, he knew, with " a 

 wealth of pathological material." At the university botanical 

 laboratories he saw " many interesting cultures and drawings of 

 Ascomycetes, hepaticae, etc.," and he was given a flask culture of 

 one hepatic which he hoped to cultivate, when again at his labora- 

 tory, to " try to obtain crown galls on it." Other work on an 

 ascomycete and cultures of '" the fungous element of lichens free 

 from algae " ^*^ interested him. But the time had arrived for Dr. 

 and Mrs. Smith to leave the city, interesting for many reasons, but 

 especially so because of the points of association with such lives 

 as DeBary's, Solms Laubach's, Pasteur's and Goethe's. From there 

 they went to Frankfurt, and then to Berlin. 



On the morning of February 25, Dr. Smith became acquainted 

 with Director Blumenthal, Dr. Auler, Miss Meyer, Dr. Kraus, head 

 of the hospital, Dr. Lewin, Dr. Hirschfeld, and Professor Brugsch. 

 To his delight he found that Dr. Auler and Miss Meyer had been 

 students of tumors, including crown gall and other plant tumors, 

 for several years. Dr. Auler had been " definitely working on 

 animal inoculations and transplants of the bacterially induced 

 sarcomas and carcinomas since September, 1923." Miss Meyer, 

 who often had been in England and spoke English, had worked
