Appearance of epilepsy in animals born of parents having
been rendered epileptic by an injury to the spinal cord.
"'2nd. Appearance of epilepsy also in animals born of parents
having been rendered epileptic by the section of the sciatic nerve.
"'3rd. 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.
"'4th. Partial closure of the eyelids in animals born of parents in
which that state of the eyelids had been caused either by the
section of the cervical sympathetic nerve or the removal of the
superior cervical ganglion.
"'5th. 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 I have
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.
"'6th. 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.
"'7th. 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.
