Thirdly, between these two clusters, there was a scaly prominent _front_ B,
which was arm'd and adorn'd with large tapering sharp black brisles, which
growing out in rows on either side, were so bent toward each other neer the
top, as to make a kind of arched arbour of Brisles, which almost cover'd
the former _front_.
Fourthly, at the end of this Arch, about the middle of the face, on a
prominent part C, grew two small oblong bodies, DD, which through a
_Microscope_ look'd not unlike the Pendants in Lillies, these seem'd to be
jointed on to two small parts at C, each of which seem'd again jointed into
the front.
Fifthly, out of the upper part and outsides of these horns (as I may call
them, from the Figure they are of, in the 24. _Scheme_, where they are
marked with FF) there grows a single feather, or brushy Brisle, EE,
somewhat of the same kind with the tufts of a Gnat, which I have before
described.
What the use of these kind of horned and tufted bodies should be, I cannot
well imagine, unless they serve for smelling or hearing, though how they
are adapted for either, it seems very difficult to describe: they are in
almost every several kind of Flies of so various a shape; though certainly
they are some very essential part of the head, and have some very notable
office assign'd them by Nature, since in all Insects they are to be found
in one or other form.
