ph±o technician, and to the best of my knovvledge, there is only 
one really good man of this kind active today — D. P. Wilson in 
England. The influence of Disney and professional incompetence 
of tradesmen like Vishniac have set serious biophotography at a 
low level in this country. Perhaps out of our trip we can get 
not only some attractive and startling photographs, but pictures 
of true significance to the biolgist. 
To come back to the flash apparatus for the under- 
w'ater housing; I will need to knovj the size flash bulb it takes. 
We will want 4 dozen bulbs, probably with a medium base, although 
I believe smaller bayonet types will work if w'e get an adapter. 
The former would be best, but I would want to check on the socket 
of the flash.

One other thing; I believe it would be best if you 
could bring along that Eolleiflex' that the Smithsonian bought 
for the und®rv;ater housing. I will take mine anyway, but I would 
like to use one of these two cameras for large-negative black and 
white work, and leave the other in the housing. 
Any new® about the shipboard current (cyclers)? I 
hope it is ACI If it isn’t, do you suppose the Smithsonian could 
supply a rectifier that would provide me with current of the 
usual household characteristics? I have to have 100 v. and it 
cannot be DC. 
This is all for now', although new questions will 
pop up soon, I am sure. 
Sincerely, 
P.S. Do you want to send the film to me? If so, 
it in v/atertight, de-humidified containers in the 
ship ahead. Again, I would have to have it about 
I can pack 
cases I’LL
