Fig. $. I. K. L. reprefents one of thofe Attwalcula , 
and I. L. the two little Shields that cover the Wings 
when it does net fly. K. is the Tail or hinder Part of 
the Body * on each fide of which are the Wings, which 
were partly folded : For that Ammalculum cannot fheath 
its Wings in the Shields, without partly folding the 
Ends of them. 
Now fince we fee that the Worms, whofe Skin is re- 
prefented at Fig. 3. are turn’d into flying Creatures, 
which lay their Young or Eggs in all Parts of a Houfe, 
and fince it is natural to all Creatures to flow their Eggs 
where they can be bed prefer v’d and hatch’d, it will 
not appear flrange, that thefe Creatures are moflly found 
upon Furs that are Fat 5 awl fo the Furriers themfelves 
have inform’d me. 
I took a little Fat of an Ox, and laid it by thefe 
Animalcule , but I could not perceive that they fed 
upon it. 
About the end of the Month of May, I fought for 
fotne Mites upon a piece of fome dry’d Flefh of a Whale, 
which hung upon a little String faflned to a Nail in 
jny Clofet ; and I perceived that feveral of the faid 
blackilh Animalcule fell off from the piece of Whales 
Flefli 5 and this happen’d four times one after another 
upon feveral Days : Whereupon I put mofl of the flying 
Creatures into a Glafs Tube, which I flopt in fuch a 
manner as not to exclude the Air $ and I put into the 
faid Tube a little bit of Whales Flefh, upon which I 
obferv’d that they fed greedily, and that a great deal 
of their Excrements lay upon the Glafs. 
Upon the 31ft of May , I faw three Eggs lying upon 
the Glafs, and they were white * but having none of 
that Vifcous Matter about them, wherewith the Eggs of 
mod of the Animalcule are endow’d, thefe Eggs did 
not flick to the Glafs, but fell among the Excrements 5 
fo that I could not diftinguifh them.
