spoonful of the castor oil mixture (castor oil, and syrups of buck- 
thorn and white poppy, in the proportions of three, two, and 
one), and rub the ammoniacal liniment on the loins. 
8 th . — The bowels are fairly opened, but the palsy continues. 
Continue the mixture and the embrocation daily. 
12 th. — The palsy extending, and the animal refusing to eat. 
Continue mixture, and add two drachms of spirit of turpentine to 
every ounce of liniment. 
14 th. — The animal died this morning. There had evidently 
been inflammation of the mucous membrane of the intestines ; 
there were still red streaks and spots, but the inflammation had 
been subdued. There had also been inflammation of the mucous 
membrane of the bladder. That viscus was filled, but not dis- 
tended with bloody fluid, and was now, and including all the 
coats, almost in a state of sphacelus. Did the palsy proceed from 
that sympathy of the lumbar and sacral nerves, and all those of 
the hind extremities, with the mucous membrane of the intestines 
which we see in so many quadrupeds? Nephritis, and afterwards 
cystisis, are likewise associated with palsy, or simulate palsy. 
Is this from the unwillingness of the animal to move, on account 
of the intense inflammation which is propagated from the urinary 
organs to the neighbouring muscles? or is it a metastasis or ex- 
tension of inflammation? — In whatever way it is to be accounted 
for, there is evident affection of the urinary organs in most cases 
of paralysis of the hinder extremities. It is a connexion well 
worth tracing, as elucidating the cause and treatment of nephritis 
and lumbo-spinal diseases. • 
1833. ’ October 26th. — Wild Boar. — Lately sent to the gar- 
dens, and not quite well when he came. He suddenly purges 
mucus and blood, and can scarcely drag his legs after him. Give 
an ounce of castor oil, and afterwards the castor oil mixture 
morning and night. 
27th. — Still purges mucus and blood — the palsy of the hinder 
extremities complete. Give the castor oil mixture. 
28th. — Dead. The disease was chiefly confined to the colon, 
the mucous membrane of which was highly inflamed. The cel- 
lular substance — the bands — forming and binding down the cells 
of the colon, was thickened and injected : it might almost be 
said to be congested. This had evidently been a disease of con- 
siderable standing, but had lately taken on an acute character. 
This connexion between inflammation of the bowels and palsy of 
the hinder extremities is common enough in the carnivora, and 
I have seen it before in the ommvora.
