Diseases of the Stomach. 69 
patient was three or four years old. He had for several 
months been subject to occasional vomiting, but this had 
“of late become more frequent. He(Mr. Ainslie) attributed 
it to the treatment of the animal when ynder distemper 
The disease had assumed its severest form, and large doses 
of calomel had been administered. From that time he had 
had fits of vomiting, sometimes without any evident cause, 
and generally after a hearty meal, and always if he took 
exercise after a meal. There was also, to the great annoy- 
ance of the owner, a continual discharge of viscid saliva 
from the corners of the mouth, and more or less blood 
accompanied every act of vomiting. The owner did not 
-seem to suspect the real origin of this nuisance. 
“On the first of the month he appeared to be as well as 
usual. In the evening he cleanly picked a bone for his 
supper, and after that came a fit of vomiting. He lay 
‘quiet during the night, and in the morning began to vomit 
mucus mixed with blood. This continued during the day; 
the dog rapidly lost strength, and died in the evening. The 
blood retained its fluid state, mixed with mucus and saliva. 
When, on the following morning, he opened the dog, and 
‘began to feel for the stomach, no viscus of that kind was to 
be found in the abdomen. He then opened the thorax, 
and there he perceived a considerable enlargement of the 
esophagus. At first sight it seemed to be a tumour 
attached to the parietes of that tube, but on closer exami- 
nation the cesophagus was evidently dilated by some large 
soft body within it. He cut into it, and drew from it the 
stomach, inverted, and its mucous coat in the highest 
possible state of inflammation. The whole of the villous 
tunic was charged with congested blood. The dilatation of 
the cesophagus commenced even from the pharynx, and had 
probably existed for a considerable time. The food, or 
some portion of it, probably remained in this dilated por- 
tion of the cesophagus, and slowly passed into the stomach, 
and that might account for the frequent vomitings an hour
