GANGRENOUS CORYZA IN THE OX.

been imprudent enough to work them, or leave them at pasture 
during the hottest part of the day, brought in at night with the 
first s}unptoms of the disease. 
All treatment is, as I have before said, useless. Astonished in 
the beginning of my practice at the fatal march of nasal catarrh in 
the ox, and never having heard of it during my veterinary studies, 
I thought it prudent punctually to follow the course usually pointed 
out in similar cases, which consisted in making one or mote holes 
in the base of the horn, and so procuring a slight bleeding, or 
amputating the horn about four inches up, which produced a copi- 
ous bleeding. In either of these cases bleeding was not so much 
the object, as the getting rid of some humour or bad blood. Irri- 
tating fumigation, composed either of withered stalks of garlic, or 
juniper berries, or pieces of old leather, are also made use of. It 
is supposed that a humour is gathered in the head, and that it is 
necessary, by every possible means, to try to get rid of it. Thus, 
when the holes in the horns, or the wound of the amputated horn, 
gives passage to a usually very inconsiderable quantity of pus, and 
the secretion of nasal mucus is augmented, it is believed that the 
humour, having found an issue, will soon be entirely evacuated. 
The animal, however, does not get well, and they console them- 
selves by throwing their want of success on the disease, which they 
pronounce incurable. 
If it happens that the matter that escapes from the wounds in 
the horns is very abundant, it cannot always be said that the se- 
cretion of it existed before the operation ; on the contrary, it may 
be the result of the operation. I have seen, when the horns were 
grown in a wrong direction, so much so as to make it difficult to 
put the animals under the yoke, and the horn which turned in was 
obliged to be amputated ; — I have seen, I say, a very great quan- 
tity of matter formed by the amputated wound in one day, although 
the animal was in perfect health before the operation. 
Not having been successful in the three or four animals sub- 
mitted to the ordinar} r mode of treatment, I thought it best to 
change it for one diametrically opposite ; therefore I began by 
taking away eight pounds of blood from the jugular vein twice 
every day. This I did for two or three successive days, according 
to the intensity of the disease and the age and strength of the ani- 
mal. I did not cease until I was convinced that the bad symptoms 
were abated. Immediately after the first bleeding I passed two 
setons through the lateral and superior part of the chest, and one 
through the dewlap. To each of these setons was attached a 
piece of black hellebore root, which I considered as the most prompt 
of all the exciting derivatives 1 could make use of. I also made
