the plucking out a Iiair tliat h firmly fixed ; aiiJ I iiavc farther 

 obfcrved, that thofe hairs wliich are pulled out by force, have large 

 thick roots, whereas, the roots of thofe wlVich are near falling oH", 

 are very fmall and pointed. 



Fig. 9, A13CDEFG, and HLMNPO, are tv.o very fmall hu- 

 man hairs with their roots ; in tliefe will be fecn, that the points or 

 Imall ends of them, at G and O, are fomewhat bent, which I attri- 

 bute to this, that the points, when tiiin and tender at their firll ex- 

 puifion from the Ikin, had met with iome obftacle in their growth, 

 which not being able to penetrate, they were bent obliquely : It is 

 not iifual to fee hairs bent at the fmall end, in the m.anner Ihewn at G, 

 but tliey moil commonly appear as at Q. 



AB, and H L, are tlie roots of thefe hairs, which do not appear 

 ib large, if tiie hair falls off of itfelf, but, when a hair is pulled out by 

 force, the root appears much larger tlian the hair itfelf, as is Ihewu 

 in this figure. 



The bending of the hairs I have noted above, may very eafily be 

 occahoned by their meeting with fome obftru6lion in their growth, 

 and having obferved a hair on my arm, wliich was very much bent, 

 i pulled it out, and placed it before a microfcope, in order to (hew 

 its figure in a drawins". 



Fig. lo, ABCDEFGHI, exhibits this hair, in which, ABC is tlie 

 root, and at AC may be leen a fmall portion of the cuticle or outer 

 Ikin, which adhered to tlie hair. DEF, indicate a confideruble bend- 

 ing in the hair, and at GEH is Ihewn a much greater bending, or 

 rather, an entire circular curve. 



I have faid, that hairs are covered with a coat or bark, in like 

 manner as trees, and that, however fmall, tliey are compoled on the 

 infide of oblong parts or iibres, and I ajn perfuaded, that there is no 

 difference between iheep's wool, whicii is the fmalleil: kind of hair, 

 and the hairs of men and animals, except, that (beep's wool confilts
