^ Q three weeks to make up my media. Though I am using methods 

 of which Martin would highly disapprove, I find it interesting 

 to make comparison of the different strains of organisms iso- 

 lated from plague and cholera. I am about to carry out some 

 work on toxine production by the cholera spirillum. 

 April 7, 1903, he wrote to his mother: 



. . . Thank you for the extract from the Civil & Military 

 Gazette on "oysters." It particularly interests me for I had 

 some work to do on oysters a few weeks ago for the board of 

 health. These Philippine oysters are all more or less dangerous 

 and the Board of Health forbade their sale; strange to say, 

 since then, there has been none of the cholera-like infections 

 which were quite frequent. Yes, we are very comfortably 

 located and have good food. Still, we find $45.00 a month 

 rather steep and if we get a chance, Woolley & I will keep 

 house. A couple of friends of ours do so and quite reasonably, 

 too. — I don't go out anywhere in the evenings excepting that 

 Woolley & I drive to the Luneta & hear the music two or three 

 times a week, and then we go to Medical Soc'y once a month. 

 Our work requires pretty steady reading & we usually spend 

 our evenings that way. We bought some interesting photo- 

 graphs the other day from the Government photographer. 

 They represent various peoples in the Island of Luzon, their 

 dress, homes, etc. We cannot send them away though, or the 

 photographer would get into trouble. One of our chemists 

 here, a Mr Stangle, is quite an anthropologist & philologist, 

 knowing many languages well. He is studying the origin of 

 the Philippine tribes and has much evidence to show that the 

 aborigines here — Igorrotes — are quite like the aborigines of 

 India — the Bhils, etc. He is anxious to get a vocabulary of 

 Indian words to compare with the Philippine, and asked me 

 if I could in any way get hold of such a vocabulary. I told 

 him that I would see if Papa could do anything. So I enclose 

 a list of words. 



His laboratory chum out of the Chicago days, Joseph C 

 Ohlmacher, cheered him from the Independence state hos- 

 pital in Iowa (April 8, 1903) : 



Even your routine, at first anyway, must be exceptionally 

 interesting, and I envy you your opportunity of doing autop-
