occur in the corium of the skin. Similar, though more highly developed, 

 end bulbs form the so-called genital corpuscles which are found in con- 

 siderable numbers in the connective tissue of the glans penis, prepuce, 

 and clitoris. In some of the smaller (cylindrical) end bulbs found in 

 the tendons, the mucous membranes, and in certain portions of the skin,

 (After Dogiel.) 



The nerve fiber shows lateral proc- 

 esses, many of which are knobbed.

the nerve fiber fails to divide but ends near the distal extremity of the 

 bulb in a small fusiform end knob. 



4. Lamellar Corpuscles (Pacinian Corpuscles, Vater's Corpuscles, 

 Vater-Pacinian Corpuscles). These are among the largest of the nerve 

 end organs. In the mesentery of the cat they are of macroscopic size, 

 varying in length from two to three millimeters. They assume the form 

 of a large ovoid thickening, placed upon the end of a nerve fiber. The
