fibres pass into the corpuscle, break up into two or three 

 divisions, and terminate in convoluted or knotted coils.

A. Three corpuscles of Krause from the conjunctiva of man, treated with acetic acid (magni- 

 fied 300 diameters ) ; after a drawing by Ludden. 1, spherical corpuscle, with two nerve- 

 fibres which form a knot in its interior. Portions of two pale nerve-fibres are also seen. 2, 

 a rounded corpuscle presenting a nerve-fibre and fatty granulations in the internal bulb; 3, 

 an elongated corpuscle with a distinct terminal fibre. In these three corpuscles, the covering, 

 nucleated in 1 and 2, is distinguished. 



B. Terminal bulbs from the conjunctiva of the calf, treated with acetic acid (magnified 300 di- 

 ameters) : after a drawing by Ludden. 1. extremity of a nerve-fibre with its bulb : '2, double 

 bifurcation of a nerve-fibre, with two terminal bulbs : a. covering of the terminal bulbs : 6, 

 internal bulb ; c, pale nerve-fibre. (KOLUKEE, Handbuch der Gewebelehre, Leipzig, 1867, 

 S. 103.) 



The nerve-fibres are medullated for a certain distance, but 

 their terminations are generally pale. The above is one
