234 GENERAL ANATOMY. 



The cheeks, the environs of the mouth and chin are occu- 

 pied by the beard, barba,julus, mystax, pappus. 



The groin is furnished with them, glandebalae, as well as 

 the yubis, pubes, the scrotum labia pudendi, and around the 

 anus. 



The rest of the body, both trunk and limbs, are more or less 

 possessed of them. On the trunk they are more numerous on 

 the anterior than the dorsal face, which is precisely the re- 

 verse of what generally takes place in animals; in the limbs 

 there are fewer on the internal side than the external one. 

 The hairs of the greater part of the body and limbs are thinly 

 scattered, very fine, short, and scarcely visible; they have no 

 particular names, and are in great numbers and highly de- 

 veloped in particular hairy individuals, homines pilosi. 



343. The rudiments of the hairs are perceptible on the 

 foetus about the middle period of pregnancy. They make 

 their appearance in the mucous body in form of globules simi- 

 lar to those of the pigment. On these globules arise little hol- 

 low cones, the sheaths of the hairs. They remain for some time 

 under the epidermis, and finally traverse it obliquely, through 

 pores, it has been said, but none are to be found. 



At an early period, on the skin of the foetus, is found a fine 

 down, lanugOj at first colourless, that covers the whole of the 

 body, and which assumes in the different regions determinate 

 directions. These silky.hairs, are, for the most part, detached 

 about the eighth month of gestation, and are found in the water 

 of the amnios, and in the meconium. It is in the last month 

 that the eye-brows, eye-lashes, and the hair begin to appear. 

 After birth the remainder of the down falls. At the age of 

 puberty begin to appear the beard, the hairs of the nose and 

 ear, those of the axillas, the pubis, the organs of copulation, 

 the anus, and those of the rest of the body. After the adult 

 period of life, and in old age, the hairs generally become white 

 and fall. 



The hairs of the head are generally longest, and most numer- 

 ous in females; they have, generally, no beard, nor hairs round 

 the anus, and those of the remainder of the body are finer and 

 more thinly scattered. After the age of fecundity the beard
