Plate Xll. Jig. 10, A B C exhibit this worm or maggots as glued 

 to the pin, and appears to the view as if it lay on its back. A is 

 the head, on which are two prominent parts, like horns, out of 

 which proceed two other Iharp weapons, fo fmall that the limner 

 did not perceive them until they were pointed out to him : between 

 thefe horns appear two fliorter prominent parts, which are not 

 placed on the head, but at the lower part of it, where the mouth

After this M'^orm had been thirty hours before the microfcope 

 and was ftill very lively, I thought I faw its body not fo com-

 evaporated. I frequently afterwards infpe6led it, and at the end 

 of fixty-four hours, I faw it fiill in motion, but its body diminifhed 

 in fize : this day the fun llione very hot. 



At the expiration of four days and nights this worm was Hill in 

 motion. I did not examine it again till fixteen hours afterwards, 

 and its body was then much contradled : the following morning the 

 moifture of it was fo evaporated, that it could not be known to be 

 a worm.
