terminals (presumably nerve endings), arranged symmetrically on oppo¬ 
site sides of the head within the amphids (trm) y lead to the belief that 
the backward processes connected with them pass to the nerve ring, 
although they have not been traced thither. It would be an interesting 
piece of work to trace them backward by means of serial sections of the 
adult nema. 
The cells of the intestine throughout its length, and some of the cells 
of the body wall, are well stocked, in the young larva, with fat globules. 
These darken in osmic acid, those in the body wall apparently more 
vigorously than those in the cells of the intestine, a difference that may 
be connected with the relative position of the two groups of globules.
