ftiould have been very glad to have given fome account 
of thisLight from Experiments that might have bin made 
thereon but not having the opportunity of doing it whiift 
the Flyes lived which was not above a day after they 
were taken, and wanting my Microfcope in the Country 
to examin it more nicely while fliining, I muit be con- 
tented with offering a Draught of the Infed fuchasi 
could then make, and a larger reprefentation of it as the 
Microfcope fliewed it being laid on its back, when it

Between thefe Eyes and the Thorax lyes the Mouth : on 
the Thorax are 6 Legs almoft all 01 a length. The Tail
