4. That the root of the Hairs were pretty smooth, tapering inwards, almost
like a Parsneb; nor could I find that it had any filaments, or any other
vessels, such as the _fibres_ of Plants.
5. That the top when split (which is common in long Hair) appear'd like the
end of a stick, beaten till it be all flitter'd, there being not onely two
splinters, but sometimes half a score and more.
6. That they were all, as farr as I was able to find, solid _Cylindrical_
bodies, not pervious, like a Cane or Bulrush; nor could I find that they
had any Pith, or distinction of Rind, or the like, such as I had observ'd
in Horse-hairs, the Bristles of a Cat, the _Indian_ Deer's Hair, &c.
_Observations on several other sorts of _Hair_._
For the Brisles of a Hogg, I found them to be first a hard transparent
horny substance, without the least appearance of pores or holes in it; and
this I try'd with the greatest care I was able, cutting many of them with a
very sharp Razor, so that they appear'd, even in the Glass, to have a
pretty smooth surface, but somewhat waved by the sawing to and fro of the
Razor, as is visible in the end of the _Prismatical_ body A of the same
Figure; and then making trials with causing the light to be cast on them
all the various ways I could think of, that was likely to make the pores
appear, if there had been any, I was not able to discover any.
