THE CORSELET. 33 



a foot stalk, and wide at top, like certain mushrooms, 

 such as those which Reaumur found in the abdomen 

 of the treehopper, and termed cartilaginous plates. 

 Like the former, they either serve for the attachment 

 of muscles (*), or assist in the mechanism of the wing 

 joints ( 2 ). 



It is farther to be remarked, that if the corselet, as 

 well as the head and abdomen, be cut exactly in half, 

 lengthwise, each of the pieces and organs on each 

 side will correspond as exactly as our own two hands, 

 or our two nostrils ; a very remarkable fact.
