OP THE HUMAN SKIN. 85

 etable parasites. We have seen that it does not 

 especially affect the hairs, is principally confined to 

 the scarf-skin, and is nothing more or less than a 

 weed among the epithelial cells. 



The proper treatment is so simple and so effica-

 no more service than dosing a river to kill the 

 weeds in the meadows watered by it. We have 

 only to macerate off the epidermis, and by the 

 application of a parasiticide prevent the germina- 

 tion of the spores until they are finally entirely 

 gotten rid of. Soaking in hot water, and rubbing 

 with strong soft soap, will remove the scarf-skin af-
