 Pou human de la fife, De Geer ; Le pou ordinaire,

 Leach According to Murray the colored races 



have lice with corresponding colors. Those of the 

 negroes of West Africa and Australia are nearly 

 black, those of the Hindoos dark, those of the 

 Hottentots orange, those of the Chinese and Japanese 

 yellowish-brown, those of the Indians of the Andes 

 dark-brown, those of the California Indian olive, 

 those of the northern Indians, Esquimaux etc., pale. 

 The lice from a negro turn light-colored when placed 

 on the head of a white person. Any simple grease 

 will destroy these parasites, a fact which perhaps ex- 

 plains the universal use of ointments and pomades by 

 all savages and people of dirty habits. — Pediculus
