Upon viewing thefe Eggs as they were placed before 
the Microfcope with the light of a Candle, we obferv’d 
an unconceivable number of exceeding fmall Lights or 
Tranfparencies in the Egg-fhell, which I imagin’d might 
be occafion’d by the unequal thicknefs of the Parts of 
the faid Egg-fhells ; and that the Tranfparency therein 
was caufed by little Holes that were thinner than the 
reft, as we fee in the Shell of a Hens Egg. 
I obferv’d fckewife that a Mite, which had been ftuck 
thro’ his Back with a point of a Pin, had upon the 
fmalleft part of one of his Legs an Egg cleaving to it ; 
and tho’ he mov’d his Foot very much, yet the Egg 
ftuck faft to it all that Day that I obferv’d it. From 
whence I concluded, that the Eggs of Mites are of the

they are furrounded ; and this was^the reafon that the 
Egg of the Mite ftuck fo faft to its Foot. But the next 
Day f obferv’d that the Mite had work’d the Egg off 
his Leg," and by the help of his Claws held it in one 
of his Feet : and tho’ he made a great ftir with his Legs, 
and particularly with that which held the Egg, yet he 
did not let it go, but took it from one Foot into the 
other ^ which was a very pleafant fight $ but the next 
Day I could not find the Egg. 
Being not content with the aforefaid Obfervations, I 
obferv’d two other Mites, which I judg’d to be Females, * 
before two Microfcopes : One of thefe Mites had laid 
two Eggs, and the other three 5 and as far as 1 con’d 
judge, they were about three Days old.* 
I carried thofe Microfcopes, together with the Mites, 
in the Day time about me : And after the fpace of Ten 
Days, I obferv'd that two of the Eggs, which lay’clofe by 
each other, had been hatch’d, and that the young Mites 
were come out of them, and the Shells lay open; but I
