Dear Wetnore: 
Having an enclosure to send you, I take occasion to say that 
Mr. Kent asks you to examine the helloas of your camera carefully to 
see whether there is not a small leak in it. He finds slightevidence 
that all of your exposures are light struck, although not to such an 
extent as to seriously damage them. 
Very taruly yours. 
Assistant Biologist.
