THE HAIRS. 93 



although they are for the most part of little importance, 

 we think we ought to give them rapidly, because they 

 will aiiord us an opportunity of passing in review the 

 different forms of hairs. I will arrange them under 

 these general classes, viz. 



1st. Glandular Hairs. 



2d. Lymphatic or Non-Glandular Hairs. 



3d. CoROLLiNE Hairs.

 fluid contained in a gland is evacuated. 



Under the name of Glanduliferous Hairs, we may 

 join those which have been called — 1st, Cupulate Hairs, 

 (pili cwpulati ; poils a cupules — PI. o. A) ; these are

 PI. 3, B) ; these are simple filaments terminated by a
