employed for the destruction of vermin infesting either animals, 

 or the habitations of man. 



A paper, containing some further remarks on the curious 

 construction of the nest of Cteniza nedulans, by Mr. Sells, 

 was read. 



A paper by the Rev. W. F. Hope, was read, in reference to a 

 passage in Kirby's Bridgewater Treatise, wherein the insect 

 that infested the Egyptians in the plague of flies, is supposed 

 to be the cock-roach. The author expressed his deference to 

 Mr. Kirby ; but on this point contested his opinion as unneces- 

 sary and unsupported. He cited many authorities for the 

 prevalence of several descriptions of fly in Egypt in the present 

 times, and concluded that there was no reason for supposing 

 that the insect designated by the Hebrew words in Exodus, was 

 a Blatta, or otherwise than a proper fly. In the discussion 

 on this paper, several members stated, that the cock-roach 

 attacked man in tropical countries, by night, at the extremities. 

 The Chairman announced that he had in preparation a paper, 

 which he hoped to have ready by the next meeting, on the 

 insects found alive in the human subject, and should be much 

 obliged by any facts or assistance thereon.
