and sizes (Fig. 10). In others the varicosities are scanty, and the 

 appearance of the terminations is totally different (Fig. 11). In 

 others again, according to Crevatin and Dogiel, one or more 

 delicate non-medullated fibres also enter the corpuscle, where they 

 ramify and form a slender plexus at the periphery of the core, and 

 also penetrate inside and mingle with the ramifications of the 

 myelinated fibres (Fig. 12). 



In the subcutaneous fatty tissue there are two other charac- 

 teristic forms of corpuscles besides the Golgi - Mazzoni bodies:
