ON INTERMITTENT HOOVE IN THE OX.

On the 15th it was distended to a very great degree. The owner 
now punctured the animal himself. It was the fourth time that 
the operation had been performed. He again fixed the canula, 
which fell out during the night of the 24th, probably in the 
struggles of the animal, who was found dead on the following day. 
Post-mortem examination . — There was adhesion of the rumen 
to the diaphragm, and to the left flank ; also to the liver and spleen. 
Beside this there was no morbid appearance in the abdomen ; but 
between the two lobes of the lungs and the folds of the mediasti- 
num, where the oesophagus passes in order to arrive at the dia- 
phragm, I found an encysted tumour of a pyramidal form, nine 
inches in length, and weighing five pounds. It was adherent by 
its base to the circumference of the diaphragmatic opening. Its 
surface somewhat resembled the cerebellum of an animal, and its 
interior presented some clay-coloured concretions. The edges of 
the pulmonary lobes were adherent to the diaphragm. 
Case II. — On the 1st of September 1837, Mr. Combes bought 
a pair of oxen, one of which became hoven on the following day. 
It was thought that he had been gorged with food, in order to give 
him a plump appearance at the fair, since, being put on somewhat 
short commons, the enlargement disappeared, and the animal ap- 
pearing to be in a state of health, he was put on the usual regi- 
men, and sent to work. 
A new meteorization, which took place on the sixth of October, 
disappeared after rumination ; but it returned, and to a greater 
extent, on the 7th, when I was summoned. The enlargement of 
the paunch took place both during work and after feeding. The 
beast also had a hoarse cough. The proprietor sold him to a butcher, 
and he was killed on the 28th of October. 
Examination after death brought into view an encysted tumour, 
in the same situation as in the first case, with this difference, that 
it was less oblong, of almost the size of a man’s head, and weigh- 
ing nine pounds. Its envelope was thick, and composed of three 
laminae; and on being punctured, it was found to contain five 
pounds of purulent matter, of an infectious odour, and of the consist- 
ence and colour of the yolk of an egg. The lungs were flabby. 
There was no other morbid lesion. 
Case III. — On the 15th of October 1831, I attended on an ox 
that had an incessant cough. The tongue protruded from the 
mouth — there was a considerable discharge of saliva — the eyes 
were haggard — the inflation of the rumen was very great, and 
every thing seemed to indicate the approach of death. 
I was at first disposed to attribute the enlargement of the paunch 
to over-feeding, and I punctured the side. The enlargement sub-
