15. Crines novi. New hairs. The black points en the faces 

 of fome people confift of mucus, which is become vneief, and 

 which adheres in the excretory ducts of the glands of the fkin i 

 as defcribed in Clafs I. 2. 2. 9. and which may be preffed out 

 by the fingers, and refembles little worms. Similar to this 

 would feem the fabrication of filk and of cobweb, by the fiii 

 worm and fpider ; which is a fecreted matter preiTed through 

 holes, which are the excretory ducts of glands. And in is prob- 

 able, that the production of hair on many parts of the body, and 

 at different periods cf life, may be effected by a fimilar proce/s; 

 and more efpecially as every hair may be confidered as a Sender 

 flexible horn, and is an appendage of the ikm. See Sect. 

 XXXIX. 3. 2. Now as there is a feniltive fympathy between 

 the glands, which fecrete the femen, and the throat, as appears 

 in the mumps j fee Hydrophobia, Clafs IV. 1. 2. 7. and Paroti- 

 tis, Clafs IV. 1. 2. 19. the growth of the beard at puberty feem? 

 to be caufed by the greater action of the cutaneous glands about 

 the chin and pubes in confeouence of their fympathy with thole 

 of the teftes. But this does not occur to the female lex at their 

 time of puberty, becaufe the fenfitive fympathy in them teems, to 

 exift between the fubmaxillary glands, and the pectoral ones -, 

 which fecrete the milk, and afford pleafure both by that fecre- 

 tion, and by the erection of the mammillae, or nipples j and 

 by delivering the milk into the mouth of the child ; this fen- 

 fitive fympathy of the pectoral and fubmaxiiiary glands in 

 women is alfo obfervable in the Parotitis, or mumps, as above 

 referred to. 



When hairs grow on the face or arms fo as to be difagreea- 

 ble, they may be thus readily removed without pain or any ill 

 confequence. Warm the ends of a pair of nippers or forcepc, 

 and flick on them a little refm, or burgundy pitch ; by 

 thefe means each fingle hair may be taken fait hold of ; and 

 if it be then plucked off ilow.ly, it gives pain ; but if plucked 

 off fuddenly, it gives no pain at all ; becaufe the vis inertia 

 of the part of the fkin, to which it adheres, is not overcome ; 

 and it is not in confequence feparated from the cellular mem- 

 brane under it. Some of the hairs may return, which are 

 thus plucked off, or others may be induced to grow near them ; 

 but in a little time they may be thus fafely deftroyed ; which 

 is much to be preferred to the methods faid to be ufed in Turkey
