 — annularnerve fibers; x. — peri-pulvinar space; P. — pulvinus; n.b. — nerve bun- 

 dle; c.h. — inner sheath; r.s. — outer sheath; H. — hilum; o.s. — corium sheath.

 to annular band (combined from two consecutive slides).

Fig. I. Surface view of sheath of vibrissa with longitudinal and annular 

 nerve fibers. Only a few of the sheath cells are sketched in. The arrow shows 

 the direction of the long axis of the hair. (Rabbit.)
