Inheritance of Acquired Characters 251 



2. Appearance of epilepsy also in animals born of parents 

 which had been rendered epileptic by section of the sciatic 

 nerve. 



3. A change in the shape of the ear in animals born of 

 parents in which such a change was the effect of a division 

 of the cervical sympathetic nerve. 



4. Partial closure of the eyelids in animals born of parents 

 in which that state of the eyelids had been caused either by 

 section of the cervical sympathetic nerve, or the removal of 

 the superior cervical ganglion. 



5. Exophthalmia in animals born of parents in which an 

 injury to the restiform body had produced that protrusion of 

 the eyeball. This interesting fact I have witnessed a good 

 many times, and seen the transmission of the morbid state of 

 the eye continue through four generations. In these animals 

 modified by heredity, the two eyes generally protruded, 

 although in the parents usually only one showed exophthalmia, 

 the lesion having been made in most cases only on one of 

 the corpora restiformia. 



6. Haematoma and dry gangrene of the ears in animals 

 born of parents in which these ear alterations had been caused 

 by an injury to the restiform body near the nib of the calamus. 



7. Absence of two toes out of the three of the hind-leg, and 

 sometimes of the three, in animals whose parents had eaten 

 up their hind-leg toes, which had become anaesthetic from a 

 section of the sciatic nerve alone, or of that nerve and also of 

 the crural. Sometimes, instead of complete absence of 

 the toes, only a part of one or two or three was missing in the 

 young, although in the parent not only the toes, but the 

 whole foot was absent (partly eaten off, partly destroyed by 

 inflammation, ulceration, or gangrene). 



8. Appearance of various morbid states of the skin and 

 hair of the neck and face in animals born of parents having 

 had similar alterations in the same parts as effects of an 

 injury to the sciatic nerve."
