BIOGRAPHICAL SKETCH 57 



were not admitted, "because there were no places for them 

 in the professions, and it never seemed to occur to the director 

 that they might wish to study for the study's sake." 



Professor Walter Hempel, who had married an American 

 wife and spoke English, received her "with the greatest 

 kindness," and made an appointment with her to visit the 

 laboratories, where he afterwards showed her many inter- 

 esting pieces of apparatus which he had invented, particu- 

 larly for his specialty of gas investigation. She says: - 



"The atmosphere for study was most promising, and I 

 was very much delighted with all I saw. Hempel impressed 

 me as a very able man, and one whose methods of gas-analysis 

 were both simple and good. . . . Hempel went over each 

 room describing to me the methods and uses of his apparatus. 

 Nothing could be more charming than his manner, and he 

 is one of the exceptionally pleasant chemists I have yet met. 

 It seems to be a sad fact that the farther removed the man 

 is from the study of life, just so far is his nature blunt. The 

 botanists have been by far the most agreeable and willing to 

 aid me. My visit to this laboratory is one of the bright days 

 of this journey." 



Dr. Hempel gave her an introduction to his colleague, Drude, 

 and she was most enthusiastic over his kindness to her. She 

 thus describes it : 



"What can I begin to say of my visit to Drude! For he 

 treated me like a prince. When I called at his home, I found 

 the number, an old two-story long building, up one flight of 

 stairs. I was shown into a very pleasant room. The servant 

 made the mistake of taking my cards to Mrs. Drude. She 

 is a bright-faced woman and, though she kept me waiting 

 to change her dress, she welcomed me heartily. I explained 

 my reason for calling, and then she went for her husband 

 who soon came. He is associated with Prantl and Engler 

 in bringing out the botanical encyclopedia. He is still quite 

 young and enthusiastic over his work. He has made a special 

 study of palms . . . and has given also much attention to 

 the geographical distribution of plants, and showed me a map 

 of the world which was divided into floras of a few districts,
