Dear Dr. Schmitt; 
Dr. Smith and I have no traps on hand 
at this time and are busily writing up our 
results of the past two years experiments, 
however, P.^r. Lee Pinnigan of the Detroit 
Aquarium, Detroit , Michigan has been fab- 
ricating the traps for the past two years. 
I am sura that he would make as many as 
you require. 
It is worth while pointing out that the 
trap catches only those organisms which 
respond v;ith a positive phototaxis to long 
wavelengths of light and with a positive 
geotaxis to short wavelengths of light. 
Therefore there are many organism which it 
falls to catch. We tried it last summer in 
Florida for inshore plankters and it was 
conspicuously unsuccessful except for crab 
larvae . 
Wishing you every success on your 
proposed expedition I remain.
