one or two bendings through the corpuscle, and end by a tapering (A) or by a dilated 

 extremity (B) near the opposite pole (often projecting beyond the general body of 

 the organ, as in B); or it may be much convoluted and ramified in its passage,

so as to render it a matter of difficulty to trace its course and mode of termination 

 (fig. 398 C). The arrangement of the cells in these corpuscles seems to vary con- 

 siderably. Sometimes they are chiefly collected at the exterior, leaving the part

traversed by the axis-cylinder free from cells and of an obscurely fibrous appearance, 

 concentrically striated in transverse section (G. Retzius); but in others there is an 

 agglomeration of cells in the centre, as in the spheroidal end-bulbs of the human 

 conjunctiva ; this is, however, denied by Retzius.
