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 antennae ? for it is a 

 remarkable fact, that the very moths, such as the 

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

 iisplay the above-mentioned phenomenon most signally, 

 nave the antennae in the males amplified with numerous 

 spreading branches, so as to present an unusually large

 nexion between those organs and the faculty of dis- 

 "cvering the presence, and even the condition, of one 

 ci 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. Clemmens, an American

 of gaining some information as to their function. The 

 article, though very interesting, is too long for quotation
