Among fome of thofe little Hairs I bad ftiav*d 
off my Chin, I difcover'd feveral whofe Roots 
were intire, but cou’d not. perceive that they had 
been touch’d by the Razors this feemed to me 
at firft very ftrarge, becaufe I had always ima- 
gin’d, that the Hair of the Head and Face did 
not change or faH off^ like that of other Parts 
of the. Body. Bi;it I confider’d how^ much 
the Skin is foftned by warm Water and hard rub- 
bing,, and that the Notches in - the Razor, which 
by reafon of their fmallnefs efcaped the naked 
Eye, when they meet with fuch Hairs, are not 
capable of Cutting off the Hair, but rather tear it 
out by the Root 5 which aUb may be the Gaufe of 
the Pain or Smart that one feels, when one is (hav-~ 
ed with an indifferent Razor. I view’d fome of 
thofe little Hairs that had the Roots on, and ob- 
ferved the fides of them to be ‘ a little Tore or 
Mangled j which I fuppofe might be occafion’d by 
the Notch of the Razor, that had kid hold of the 
Hair in that Part, and fo pull’d it out. 
I have moreover bufy’d my fdf in cbferving the 
Mufcles of the Cod-fifhi and obferved that none of 
the fraali Particles, that compofe the faid Mufcles, 
were thicker than the fingle Hair of a. Man’s Chin 5 
but they were of feveral (izes, fome of them be- 
ing- not half fo big as others. When the Parts of 
the Fifh were dry, I cut fome of thefe Mufcles a- 
crofs with a Razor, which I fet and prepared af. 
ter the manner mention’d in my former Letter 5. and 
I obferved in fome of thofe Mufcles- fo cut, as ma- 
xiy fmall Streaks as- there were Notches rinvifible 
andeed, to the naked Eye) in the aforefaid Razor, 
in(brauch that we who obferv’d it were , amazed at 
it
