they are provided : From these, young Lice come forth perfect in all their Members, and
undergo no other Change but an Increase of Size.
Mr. LEEUWENHOEK discovered, that the Males are armed with Stings in their Tails,
which the Females have not ; and as he felt little or no Pain from seven or eight Lice
that were seeding on his Hand at once, he imagines the smarting Pain they sometimes
give must arise from their Stinging, when made uneasy by Pressure or otherwise ; for if
roughly treated, they may be seen to thrust out their Stings.
MOUFET makes a Difference between the Lice of the Body and those of the Head :
The latter (he tells us) are larger, longer, flatter, and more nimble ; the former fatter,
rounder belly'd, slower, and of a whiter Colour, with some blackish Lines or Streaks.
He also informs us, that if Lice are rubbed gently between the Thumb and Finger, they
feel as if they were square, and somewhat harder than Fleas; from which, by so doing,
they may be distinguished even in the dark.
Having now described and explained all the Plates Dr. HOOKE has left
of Objects examined by the Microscope, with such Brevity and Plain-
ness, as may, 'tis hoped, be useful and agreeable ; and added thereto
many Observations on the Subjects he has laid before us, in order to
make this Work more valuable : We shall take leave of the Reader,
with this single, but necessary Reflection : That whenever we behold,
in any of the Operations of Nature, whether great or small, a Con-
trivance, a Regularity, a Beauty, that both delights and surprizes,
we should not pass it over without Consideration as a Matter of mere
Amusement, but take Occasion from thence, to raise our Thoughts
from the Creature to the Creator, and therein contemplate and adore
the Almighty Power, the Incomprehensible Wisdom, and the Insinite
Perfections of the Deity.
