218 HAIE CYSTS. 



white. The black hair presented the appearance as though it 

 had been compressed closely together, and afterwards thrust 

 into the Cyst, while the white hair appeared as though it 

 had been carefully twisted into small circles and deposited 

 within. Both the black and the white hair was completely 

 free from any direct attachment to the Cyst. Many of the 

 hairs measure six inches in length. It had evidently grown 

 from the surface of the Cyst, and been regularly cast. Upon 

 removing the white hair from the sac, it took on a beautiful 

 spiral curl. The black hair was thickly covered with small 

 particles of a grease like substance. The white hair was 

 perfectly free from any such outward deposit. 



From the inner surface of the Cyst, white and black hair 

 was growing in abundance ; this inner surface was of a delicate 

 pinkish- white colour, and appeared to be free from all traces 

 of a cuticle. 



The other cases I have met with were precisely similar in 

 character to the above. In every instance the Cyst was carefully 

 removed, and the structures injured by the operation were 

 treated as a common wound.
