THE SKIN AND KIDNEYS 



TO/ 



At the roots of the hair are the openings of small glands, 

 which make an oily substance. This oils the hair and 

 skin, and makes it soft and glossy. Each hair has a little 

 muscle, which can pull upon the hair so as to make it 

 stand straighter. 

 Cold air makes 

 the little muscles 

 act, and pulls 

 the hairs of the 

 body straight 

 up, so that their 

 roots form little 

 points above the 

 flesh. We call 

 these points 

 goose flesh.

 brushed so as to keep it clean and to spread the oil over 

 it, it will look well without using hair oil or powder. On 

 the other hand, most hair oils and restoratives contain 

 substances which are harmful. Hair dyes are still more 

 poisonous. They never make the hair look natural, 

 and the lead which they often contain may poison the
