"7Q stopping her chyluria. I am now hunting for a dog with filaria- 

 sis. We intend to saturate him with quinine and then expose 

 him to x-rays. I got the idea from Musgrave and it seems as 

 though we might have some success by such procedure. But, 

 of course, we must test it upon some lower animal first. Then 

 I have been working nights trying for a photo of the filaria. 

 A good picture has never been published. After many attempts 

 the government photographer, Mr Martin, succeeded in get- 

 ting one for me of about 390 diameters. This has taken much 

 time, as it is over two miles to the hospital. Just now our work 

 is greatly interfered with, for we have moved into the new 

 building which is in a very unfinished condition and it is 

 impossible to do anything with carpenters, plumbers, etc 

 working about. 



An earlier letter to me (August 6, 1904) was devoted 

 entirely to W E Musgrave's discoveries. In May he had sent a 

 similar epistle to Hektoen and in July (as we have seen) to 

 Miss Nast. Here he was again dinning into a receptive ear the 

 importance of another fellow's accomplishment: 



I have had something on my mind that has been worrying me. 

 The most important work that has been done out here has been 

 carried on by Dr Musgrave who has succeeded in cultivating 

 a single species of amoeba in pure culture with one species of 

 bacterium. A number of pathogenic and nonpathogenic bac- 

 teria serve as food supply for the amoebae, and with such "pure 

 mixed cultures" Musgrave has established the etiological role 

 played by these protozoa in amoebic dysentery. His work will 

 be published before long. Now it seems to me that Musgrave's 

 work opens up the way to important investigations in physi- 

 ology. A sufficient and constant supply of such unicellular 

 organisms has never before been available and now all you have 

 to do is to cultivate them as you would so many bacteria. . . . 

 I thought of working on the factors influencing their stream- 

 ing or their movement but I simply cannot find the time. . . . 

 With Musgrave's consent I am sending you three cultures on 

 agar slants. . . . The agar medium is made as follows . . .
