And by examining the _Cornea_ or outward skin, after I had stript it off
from the several substances that lay within it, and by looking both upon
the inside and against the light.
_Next_, that of those multitudes of _Hemispheres_, there were observable
two degrees of bigness, the half of them that were lowermost, and look'd
toward the ground or their own leggs, namely, CDE, CDE being a pretty deal
smaller then the other, namely, ABCE, ABCE, that look'd upward, and
side-ways, or foreright, and backward, which variety I have not found in
any other small Fly.
_Thirdly_, that every one of these _Hemispheres_, as they seem'd to be
pretty neer the true shape of a _Hemisphere_, so was the surface exceeding
smooth and regular, reflecting as exact, regular, and perfect an Image of
any Object from the surface of them, as a small Ball of Quick-silver of
that bigness would do, but nothing neer so vivid, the reflection from these
being very languid, much like the reflection from the outside of Water,
Glass, Crystal, &c. In so much that in each of these _Hemispheres_, I have
been able to discover a Land-scape of those things which lay before my
window, one thing of which was a large Tree, whose trunk and top I could
plainly discover, as I could also the parts of my window, and my hand and
fingers, if I held it between the Window and the Object; a small draught of
nineteen of which, as they appear'd in the bigger Magnifying-glass to
reflect the Image of the two windows of my Chamber, are delineated in the
third _Figure_ of the 23.
