II. — Striped Muscular Tissue attached to Hair 

 Follicles. 



While making an examination into the structure of the 

 tactile hair follicles, I found that they are moved by muscles 

 composed of striped muscle tissue^ and that they differ in this 

 from the ordinary hair follicle. 



These striped muscle fibres are very long and slender ; they 

 vary in number ; in some parts there are only two or three, in 

 others seven or eight. They have no special fibrous tissue 

 surrounding them, but run side by side in the connective tissue 

 round the follicle. 



They are inserted into the follicle near the base, on either 

 side. Their insertion appears to extend for some little distance 

 round the base, and in the central portion of the insertion the 

 most fibres are found. They run to the surface close by the 

 side of the follicle at its wide part, but where it narrows 

 they suddenly diverge, and, proceeding obliquely, terminate in 

 the fibrous tissue. 



In many cases they can be traced to the fibrous tissue 

 lying under the superficial epithelium.
