Moreover, I placed before 4 diftin& Microfcopes a 
great Mite, which I judged to be the Female, and ftuck 
upon the Point of a fmall Pin, to the end that I might 
the better view thofe Pam which are taken for Hairs: 
and I obferved little* Joints in each of thofe hairy Par- 
ticles j and when I turn’d the Mite a little on one fide, 
I cou’d not fee thole fmall Parts any more. From whence 
I concluded, that thofe hairy Parts were provided with, 
two very fmall Hairs, all along oppofite to each other : 
So that when one fide was turn’d to the fight, the o- 
ther cou’d not be feen 5 but the Painter difcover’d ’em 
better than I could. * 1 
I dbferv’d that one of thefe Mites, after (he was ftuck 
upon the point of a Pin, laid two Eggs > one of which 
appear’d to the Eye like a great grey Pea, and the other 
I judged to be like a Sparrows Egg. Another Mite had 
laid 4 Eggs , and another, which I had newly placed 
before a Microfcope, laid two. The Mite that had laid 
4 Eggs, was only faftned by the two hinder Legs of the 
Left fide of her Body 5 fo that fhe cou’d move the fore- 
part, and even difplace it : And I obferv’d, that after 
the faid Mite had ftuck upon the point of a (harp Pin 
for the fpace of 10 Days, fhe had eaten two of her 
Eggs*

and took two Eggs out of one of them 5 and one time 
i took three Eggs out of the Body of another, which 
were come to their full growth 5 but in the mod of 
them I cou’d difeover no Eggs : But fome of them I 
Imagin’d to be Males. And tho’ the Liquid Matter of 
the Eggs, which I took out of their Bodies, was exha- 
led in very Ihort time 5 yet thofe Eggs, which the Mites 
had laid, preferv’d their perfeft bignels and roundnefs. 
The reafon of which was, as I imagin’d, that the Shells 
of thofe Eggs which I had taken out of their Body, 
had n©t yec acquir’d their full hardnefs, <tnd confe-
