works of a Creator, who has made nothing in vain, and 

 therefore nothing beneath our notice, and who has Himself 

 pronounced his creatures to be good. The loss of this philoso- 

 pher will long be felt. It requires ages to produce a Homer 

 or a Shakspeare ; and ages elapse between the lives of an 

 Aristotle and a Cuvier. We feel that we should be rendering 

 an acceptable service to our readers, by giving some account 

 of the life of this great man :. our limits preclude it. His coun- 

 trymen, with that fine taste for which they are so remarkable, 

 have planned a monument to his memory, the expense of which 

 is to be defrayed by the sale of works on any branch of natural 

 history, which their respective authors are invited to transmit 

 to agents appointed to receive them ; first, however, writing 

 their own names in each, and some short observation, demon- 

 strative of their respect for the deceased. We call on our 

 countrymen to assist in such an undertaking ; let not Britain be 

 behind other nations in demonstrating esteem for sterling 

 merit. M. Bailliere, 219, Regent street, is appointed one of 

 the agents to receive and transmit such works. — Ed. 



19. Capture of Polypogon derivalis. — Sir, I perceive it is 

 your intention to devote a page or two of your magazine, to 

 record the capture, &c, of rare insects: I therefore transmit 

 to you the following account of the capture of that scarce 

 Lepidopterous insect — Polypogon derivalis. On the 9th of 

 last August, I took one specimen in Collyer's Wood, Green 

 Hithe, Kent; I believe it is only the second specimen that has 

 been taken for nearly thirty years : the other was taken at 

 Birch Wood, about three years since, and is now in the cabi- 

 net of Mr. Bentley. J. Chant. 



20. Cause of Sound emitted by Cychrus rostratus. — Sir, 

 Among the comparatively small number of insects which have 

 the power of emitting voluntary sounds, Cychrus rostratus has 

 long been known ; but I am not aware that the manner in which 

 it produces its sound, has ever been correctly described. 

 Neither Curtis nor Stephens allude to it at all. Mr. Kirby 

 says, " Two other Coleopterous genera, Cychrus and Clytus, 

 make their cry of noli me langere, by rubbing their thorax 

 against the base of the elytra ; " and the form of these parts, in 

 Cychrus, seems such as might justify the opinion. An addition
