O ^ Q new Institute of hygiene here. It is a wonderful place and you 

 must visit it. I doubt if the USA has its equal in beauty of 

 design and few places only can excel it in equipment. Through 

 the help of Dr Bermudez we have met the chief jefes who 

 promise all sorts of things. P W Monroe, a leading American 

 physician and surgeon here, has been most kind; and H Mooser, 

 the Swiss pathologist & bacteriologist at the American hospital. 

 He has assigned to us our first two cases — cultured by himself. 

 He is very clever and has done a lot on rat-bite fever; has many 

 things going all the time. He's a regular Mexican, or Swiss, 

 "Rosenow." 



Time is going fast and unless we get more cases soon, the 

 expedition will be a fizzle. We have been unable to insist upon 

 the fulfillment of promises made to us heretofore because we 

 did not have our materials ; but in a few days we will be able 

 to push the inspectors to report all febrile cases for culture. 

 I brought along a tube of vaccine to immunize Foshay but used 

 it up in treating Mooser's cases. One was a relapse, the other 

 a German girl of 24 yrs in the second week. After 6 daily doses 

 their temperatures came to normal. Hope this means some- 

 thing. Mooser says that if cases appear as in previous years he 

 may be able to give us 5 0. 



If I had had a little foresight I might have run down to-day 

 to see you and returned Sunday, but I was so anxious to get 

 the lab established and media ready that I left the hotel early 

 this morning without thinking of the possibility. On the way 

 home I got lost and did not get back to the hotel until late. 

 It is I who will have to push things or we may not get enough 

 cases to warrant the expenditures. 



Before returning from Mexico for his work in Cincinnati, 

 he wrote his daughter who with Marie had preceded him to U S 

 (September 11, 1927): 



I sent off a scrappy note to mother this morning — in a hurry, 

 as I got up late. Please thank her for the check for fifty dollars. 

 I am about out of my own money for my accounts didn't come 

 out square last week and I had to put twenty pesos in the fund! 

 Le Blanc & Thomas have not yet returned from Cuernavaca. 

 I expect them this evening. 



I despise the thought of not seeing you before you leave for
