On inquiring into the history of the case, the owner said, that 
about four weeks previously he had squeezed a “ warble” (the larva 
of the oestrus bovisj from the back of the animal through the 
opening alluded to, and since he had done so, there had been a 
gradual swelling of the adjacent parts, which had, by the time 
she was placed under treatment, attained such a size, and had in- 
terfered so much with the general health of the beast, that appre- 
hension was entertained for her safety. During the time that the 
swelling had been forming no remedial means had been em- 
ployed to counteract Its progress, so that the skin, in addition to 
being rigidly stretched over the tumour, had become dry and hard. 
Emollient applications and poultices were applied for a day or 
two, but these did not produce any other effect than that of 
merely softening the skin, and as there were no signs of fluctua- 
tion, and as the tumour continued to increase in size, and mate- 
rially affected the health of the cow, it was deemed advisable to 
make several free incisions through the skin and lumbar faschia, in 
order to relieve the deeper seated parts from the pressure under 
which they were suffering. Nothing but blood, and that not in 
large quantity, came from the openings made, and the poultices 
were again employed. When this course of treatment had been 
adopted for little more than a week, there was an appearance of 
sloughing round the original wound or opening ; the tumour had 
become much less tense and painful, and although its apparent 
size had not perceptibly diminished, yet the cow w'as much livelier, 
and fed tolerably well. In a few days more a piece of skin, about 
four inches in diameter, had so far become detached as to be easily 
removed, when a large effusion of lymph was seen lying between 
the skin and lumbar faschia. The lymph was taken away with the 
hand, when several imperfectly suppurating points were seen on 
the surface of the faschia, which was tightly spread over the swell- 
ing underneath. Several long and deep incisions were made 
through the faschia in various directions into the swelling, but a 
very inconsiderable quantity of matter escaped, and that which 
was evacuated did not present the appearance of healthy pus. 
The wound or sore thus formed was now dressed with nitric acid 
lotion and digestive liniment. For a while the discharge was of 
a foetid character, and the healing process tardy ; but by this time 
(May 15th) all the parts have assumed a healthy character, the 
swelling has very considerably diminished, and the size of the 
sore has materially decreased, so that, according to present appear- 
ances, in another fortnight or so, the healing process will probably 
be completed. The health of the cow is quite restored, and she 
yields as much milk as before the disease made its appearance. 
The case of bysteriUs occurred in a white short-horned cow, the
