"Now, which of our five senses, I would ask — even if 

 developed into extraordinary acuteness in the insect — 

 would account for such an exhibition of clairvoyance as 

 this? 



May not, then, this undiscovered sense, whatever 

 may be its nature, reside in the antennas 1 for it is a 

 remarkable fact, that the very moths, such as the 

 Eggers, the Emperor, the Kentish Glory, &c., which 

 lisplay the above-mentioned phenomenon most signally, 

 nave the antennce in the males amplified with numerous 

 spreading branches, so as to present an unusually large 

 sensitive surface. This seems to point to some con- 

 nexion between those organs and the faculty of dis- 

 covering the presence, and even the condition, of one 

 of their own race, with more, perhaps, than a mile of 

 distance, and the sides of a wooden box, intervening 

 between themselves and their object. 



Whilst writing this, the current number of the 

 "Entomologist's Weekly Intelligencer " has arrived, 

 and I there read that Dr. Clem mens, an American 

 naturalist, has been lately experimenting on the an- 

 tennas of some large American moths, for the purpose 

 of gaining some information as to their function. The 

 article, though very interesting, is too long for quotation 

 here ; but it appears that with the moths in question, 

 * deprivation of the whole, or even part of the antenna?, 

 interferes with, or entirely annihilates the power
