net. tl m cave was very hot, humid sad ill- smelling because of the large accumula- 
tion >f guano. the puio was inhabited by thousands of tenebrionid beet; lee. 1 col- 
lected no greet number of these beetled because Sr. J* Gates Clark had taken theta the 
ye&r previous. Z had prepared 12 quart jars, filled them half full of ureter, placed 
ia 1 level teaspoon of detergent (Breft) and about 15 drops of 25% lindane emulsion. 
The 12 bate were captured and placed ia the jars and capped. Dr. Schmitt caught 5 
and 1 caught 7. The lindane soon killed the hats. Hie scientific name of the bat 
is Brachvnhvlla cavernoma . By the time the collecting wm finished, ve veto soaked 
to the skin with perspiration. Bewan helped get the bats in the jars, which was 
darns essentially m on© would take insects out of the bottom of & net. I had on 
heavy rubber gloves to pr event bites. We were back in English harbor by 1200, and 
1 spent the afternoon estreating the parasites. Desmond was not satisfied with the 
pictures taken ia the Earning, Be had developed the negative right away. So he 
end Dr. Schmitt vent beck to try again and was successful the second try. Desmond 
also retrieved seme of the guano to use as fertiliser ia his garden.

The technique for extracting the parasites from the bats is as follows. The jar 
ia which the bat was placed with the insecticide detergent mixture, was shaken IDS 
times to dislodge the parasites. The animal was removed and placed in an enamelled 
pan and washed in a slow stream of water to remove remaining parasites still 
clinging to fur. Car© w m taken to save all the wash water which was than poured 
through a 60-seah sieve. Then the lindane-detergent mixture we® poured through the 
same sieve. The debris and parasites ware washed to one end of sieve, then reversed 
and washed lata enamel pan. The arthropods were pipetted into vials, each pan of 
washings examined carefully under a stereoscopic microscope for smaller specimens,
