After section of the sympathetic trunk in the neck 
there was produced a particular change in the form of 
the ear or a partial closing of the eyelids, and the same 
modification of the ear, and the same closure of the 
eyelid were reported in their respective descendants. 
A lesion of the medulla oblongata produced exophthal- 
mos in certain guinea pigs and the same exophthalmos 
showed itself in the young. 
Ecchymoses accompanied by dry gangrene and other 
alterations of the nutrition of the ear have been reported 
in the descendants of individuals in which this series of 
phenomena had been produced by a lesion of the restiform 
body. 
Certain other guinea pigs in which section of the 
sciatic nerve had rendered the hind foot insensible to 
pain gradually destroyed their toes by gnawing them; 
it is reported that in their descendants parts of the toes 
or even whole toes were missing from one of the hind
