"Micrographia Some Physiological Descriptions of Minute Bodies Made by Magnifying Glasses with Observations and Inquiries Thereupon"


Observing one of these in my _Microscope_, I found, in the first place,
that all the Body, Legs, Horns and the Stalks of the Wings, were covered
over with various kinds of curious white Feathers, which did, with handling
or touching, easily rubb off and fly about, in so much that looking on my
Fingers, with which I had handled this Moth, and perceiving on them little
white specks, I found by my _Microscope_, that they were several of the
small Feathers of this little creature, that stuck up and down in the
_rugosities_ of my Skin.
Next, I found that underneath these Feathers, the pretty Insect was covered
all over with a crusted Shell, like other of those Animals, but with one
much thinner and tenderer.
Thirdly, I found, as in Birds also is notable, it had differing and
appropriate kinds of Feathers, that covered several parts of its body.
Fourthly, surveying the parts of its body, with a more accurate and better
Magnifying _Microscope_, I found that the tufts or haires of its Wings were
nothing else but a congeries, or thick set cluster of small _vimina_ or
twiggs, resembling a small twigg of Birch, stript or whitned, with which
Brushes are usually made, to beat out or brush off the dust from Cloth and
Hangings. Every one of the twiggs or branches that composed the Brush of
the Feathers, appeared in this bigger Magnifying Glass (of which EF which
represents 1/24 part of an Inch, is the scale, as G is of the lesser, which
is only 1/3) like the figure D.
