thefe cryfales were very prettily Ihaped, for in tliciii I could plainly 

 fee their eyes, curioufly formed of various optical organs, having the 

 refemblance of bunches of grapes ; and I alfo thought that each eye 

 confifted of more than two hundred fuch optical organs, befides 

 which there were plainly to be feen the like joints, rings, or creafes 

 as in the maggots, allb the horns on the head, the feet, and the 

 Ihells or cafes for coverings to the wings ; and, in a word, there 

 appeared fo many and fo great perfections in this infigniticant ani- 

 mal, that I could not view them without allonillmient. 



In about three weeks from this time, my occafions having called 

 me out of town for a few days, I obferved at my return that all the 

 animals which I had put into a box were changed into flying crea- 

 tures, excepting two or three who were dead and their bodies dried 

 up, and thefe [ fuppofcd I had injured in taking them out of the 

 wood. I alfo faw eight flying animals, which had ifliied from the 

 fmall piece of wood I had put into a glals tube, fitting upon the 

 wood, and feveral round holes pierced in the w^ood, through which 

 I concluded they had efcaped 



Thefe flying animals were, in my judgment, fix or eight times 

 larger than that which is produced from the maggot which feeds 

 on the oily fubllance of Wace, of which I have treated at large in 

 another place. The fliells or calcs alfo, -which cover the wings, 

 are nearly of the fame fliape in both fpecies. 



From hence we fee that fuch young flioots of oak, as I have be- 

 fore mentioned, are more liable to be con fumed by maggots than the 

 larger pieces growing in this country, and much more flill than 

 thofe which grow in warmer regions : and for this there can be no 

 other reafon afligned, than that thofe fmaller pieces of wood, which 

 afc the flioots which fpring from the roots of old timber trees, and 

 grow up into faggot wood, are in this country very flow in growth, 

 and confequently very porous ; whereas the pieces or flioots of oak 

 which are of quick growth are firm and folid, and thefe maggots
