Under this treatment most of the abnormal symptoms 
gradually left her: she was taken to work again about the 
1st of May, and has continued to do well ever since. 
I saw her on the 13th of May, when she had very much 
improved in condition, but there was still a visible trace of 
stiffness or dragging of the off limbs, more particularly the 
hind one, and when first taken out of the stable a slight 
quivering or twitching was to be seen about the rectus 
muscle. To be brief—for I am afraid I am trespassing too 
much on the pages of your journal—in explaining the symp¬ 
toms observed in this case, I think it will appear tenable, 
according to physiological research, that the immediate cause 
of epilepsy in this case was congestion, causing irritation of 
the sensible structure of the encephalon; that the parts more 
immediately involved were the corpora quadrigemina, crura 
cerebri, pons varolii, and medulla oblongata ; the third, fourth, 
and sixth pairs of nerves being all principally motor, and 
taking their origin from those parts; and the fact of those 
muscles under their immediate influence being convulsed, and 
also as to the second pair arising from the thalami nervorum 
opticorum, and winding round the crura cerebri, which were 
temporarily paralysed, is strong suggestive evidence on this 
point. As to the exciting cause, 1 must decline to offer an 
opinion, but shall leave your readers to form their own from 
the history, symptoms, and treatment of the case.

The following case came accidentally under my notice 
while visiting a patient at the same place where the horse in 
question was located. 
History .—The subject was an aged gray gelding, of the 
light cart-horse breed, the property of a small farmer near
