Dear Carleton; 
Welcome to the Alpha Helix ! I hope your trip will be as satisfying, 
personally and professionally, as ours was. This was by far the most successful 
of all our expeditions! in terms of numbers of subjects, (in)accessibility of 
locales, and particularly the quality of laboratory preparations and analyses. 
The creature comforts have spoiled us for all future field work! 
There are two main points: 1) X-ray equipment. This is all explained by 
our radiologist, Dave Gundy, and will be conveyed to you by Dave Helland, the 
resident technician, who is a tower of strength and competence. After you have 
finished with it, please label carefully for return to us. It*s a bit creaky . 
and cranky after 6 years and 3 expeditions, but we (i.e.. Gundy) picked up lots 
of pneumonia, tbc, chronic lung disease of other kinds, etc. 
2) There are two tubes of cultured swabs and scrapings from trachoma 
patients. They are labelled MOELLERING; we have put them in your deep freeze 
and hope you will keep them at -70°C, with your own samples, bring them back to 
NIH, and then notify me or Dr, Robert C. Moellering, Massachusetts General 
Hospital, when they arrive, We*d like to have them typed at the Harvard School 
of Public Health, where there’s a laboratory that specializes in trachoma 
typing. 
Your itinerary makes us green with envy. We did our usual exhaustive (and 
exhausting) work-up on two populations, but you've picked some real exotica! 
Best of luck. 
A1 Damon
