5 i; ether, 3 i; water, § ii. Half of that quantity was given 
and the animal began to have very violent spasms of the neck, 
ejecting, through mouth and nostrils, finely masticated feed 
and saliva. Those cramps lasted several minutes, when the 
colt suddenly appeared to be very easy, resting the head on 
the manger in a sleeping manner. Noticing that, 1 approached 
to examine the tumor, but, to my surprise, it had entirely 
disappeared. Those injections were repeated during the day 
three times at the interval of three hours and no more tumor 
reformed, nor did any more spasms reappear. The jabot still 
exists, but without its contents. The colt eats hay, drinks 
water and swallows without difficulty. I gave before leaving 
order to turn the colt out again on the grass, to give no grain 
nor corn, nor put him to work for three months. On Novem¬ 
ber 12th I revisited the patient and found still the existence of a 
small, soft tumor, that can be easily reduced and pressed with¬ 
out pain. I had him taken to the barn, fed on corn and hay in 
my presence. He swallowed large balls of masticated food 
regularly without trouble. I saw these food-balls pass down 
the oesophagus in the jabot, come out distinctly under the 
muscles, leave the jabot and continue their passage to the 
stomach without causing the least spasmodic pain. The pro¬ 
prietor remarked to me that a few days after my first visit the 
colt had several spasms again and that the lump reappeared 
again large and full; but that by injecting the above mixture, 
he relieved the animal immediately of all distressing symp¬ 
toms. 
Remarks .—Of the three cases now on record, the direct 
cause of the complaint can be traced in one to dry food 
straw) that was not sufficiently salivated ; in the second one,) 
to green alfalfa, that was probably too voraciously swallowed ; 
in the third case, reported by Dr. R. R. Morrison, to a sup¬ 
posed carrot (although masticated food was found in the 
jabot). From the similarity of the symptoms in these three 
cases, 1 can reasonablv conclude to the existence of the same 
nature of disease, so that in all certainty, there was no total 
obstruction in any of them. In all three cases an intense ir¬ 
ritation of the ganglionar and pneumo-gastric nerves was 
manifestly expressed by the lightest pressure on skin or mus-
