246 Of Hairs. 
Moufe’s Belly are leaft opake, and fitted; for 
the Microfcope. 
The Hairs of Men, Horfes, Sheep, Hogs* 
&c. are compofed of fin all, long, tubular 
Fibres or fmaller Hairs, encompafied with a 
Rind or Bark? from which Structure a fplit 
Flair appears like a Stick fhivered with beat¬ 
ing. They have Roots of different Shapes 
in different Animals, become lengthened by 
Propulfion, and are thicker towards the 
Middle than at either End. 
Hairs of hidtan Deer are perforated from 
Side to Side : our Englijh ones feem covered 
with a Kind of fcaly Bark. The Whifkers of 
a Cat, cut tranfverfely, have fomewhat in 
the Middle like the Pith of Elder. * The 
1 
Quills of Porcupines or Hedge-hogs have 
alio a whitifh Pith in a Star-like Form : and 
a human Flair cut in the fame Manner fliews 
a Variety of Veffels in very regular Figures. 
Hairs taken from the Head, the Eye¬ 
brows, the Nofcrils, the Beard, the Hand, 
and other Parts of the Body, appear unlike, 
as well in the Roots as in the Hairs them- 
felves, and vary as Plants do of the fame 
Genus , but of different Species.
