Dear Dr, Schmitt: 
Your letter of December 2 was most welcome and I am pleased to be 
incliided in the Smith sonian-Bre din Caribbean Expedition for 1959* 
As you had suspected, I have been in touch with Carl Shuster for 
advice. I am taking the liberty of proceeding with arrangements to 
procure a passport. Are there any special instructions I need in 
this regard? 
I would like to concentrate on collecting Culicidae, particularly 
species which breed in Bromeliaceae, and similar habitats, I shall be 
arcdous to obtain reared associations, therefore will need a good quantity 
of distilled water for this rearing. Will you have a supply along with 
the alcohol and formalin? Would it be possible to obtain it locally? 
It occurred to me that it would be interesting to operate a New 
Jersey insect light trap aboard ship each night during the trip. We 
have plenty of these instruments on hand but they are all adapted for 
110 volt, AC current. Would you give me the details on the electrical 
system aboard the craft which will be used? Since these traps have an 
electric fan mounted, inside, it probably will be necessary to purchase 
a different kind. 
Would it be possible for me to arrange to visit the Rockefeller 
Medical Laboratory in Trinidad? I believe Dr. Downs is the Director. 
I am interested in their work on insect-borne diseases, especially 
yellow fever. 
This disease brings to mind immunization for the trip. What diseases 
should we be immunized against? I definitely will want a yellow fever 
booster since I might be sampling mosquitoes which are its vectors. How 
about typhus fever?
