from one of which I could see a very bright reflection of the window, which
made me ghess, that the _Cornea_ of it was smooth, like those of bigger
Insects. Its motion was pretty quick and strong, it being able very easily
to tumble a stone or clod four times as big as its whole body.

At the same time and place, and divers times since, I have observed with my
_Microscope_, another little Insect, which, though I have not annexed the
picture of, may be worth noting, for its exceeding nimbleness as well as
smalness; it was as small as a Mite, with a body deep and ridged, almost
like a Flea; it had eight blood-red legs, not very long, but slender; and
two horns or feelers before. Its motion was so exceeding quick, that I have
often lost sight of one I have observed with my naked eye; and though, when
it was not frighted, I was able to follow the motions of some with my
_Microscope_; yet if it were never so little startled, it posted away with
such speed, and turn'd and winded it self so quick, that I should presently
lose sight of it.

When I first observ'd the former of these Insects, or Mites, I began to
conjecture, that certainly I had found out the vagabond Parents of those
Mites we find in Cheeses, Meal, Corn, Seeds, musty Barrels, musty Leather,
&c. these little Creatures, wandring to and fro every whither, might
perhaps, as they were invited hither and thither by the musty steams of
several putrifying bodies, make their invasions upon those new and pleasing
territories, and there spending the remainder of their life, which might be
perhaps a day, or thereabouts, in very plentiful and riotous living, might
leave their off-spring behind them, which by the change of the soil and
Country they now inhabite, might be quite alter'd from the hew of their
_primogenitors_, and, like _Mores_ translated into Northern _European_
Climates, after a little time, change both their skin and shape. And this
seems yet more probable in these Insects, because that the soil or body
they inhabit, seems to be almost half their parent, for it not only hatches
and brings those little eggs, or seminal principles, to perfection, but
seems to augment and nourish them also before they are hatch'd or shaped;
for it is obvious enough to be observ'd, that the eggs of many other
Insects, and particularly of Mites, are increas'd in bulk after they are
laid out of the bodies of the Insects, and plump'd sometimes into many
times their former bi
