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

Other individuals in which the sciatic nerve had been 

 cut had descendants which exhibited at first a diseased
