Finding it impossible to bring the foetus out, the head is cut off, 
the front legs, which in being crossed are pressing against the 
anterior border of the pubis, are straightened, and by moderate 
and regular traction the animal was happily delivered, the opera¬ 
tion lasting about half an hour. The cow remained in perfect 
health after the operation .—Archives Veterinaires.

DISLOCATION AT THE HOCK JOINT OF A COW. 
Last month a valuable short-horn cow, belonging to the Ohio 
State University, slipped as she was going into the stable, and 
fell upon her side. On attempting to get up it was seen that the 
near hind leg was dislocated outwards and forwards at the hock 
joint. The end of the tibia formed a prominence on the inside 
of the limb, while on the outside the calcis and astragalus were 
equally out of line. The cow, although in good flesh, was too 
valuable to be slaughtered, and therefore an attempt was made 
to reduce the dislocation. A broad strap was put round the leg 
close below the joint, and with this an assistant drew the leg very 
gently but forcibly backwards. As soon as the displaced bones 
were brought opposite their proper places sudden pressure on the 
end of the tibia with one hand and a little rolling backwards, and 
pressure inwards upon the astragalus with the other hand brought 
the bones into place with the usual snap. The time occupied in 
reducing the location was less than will be reqnired to read this 
brief report of the case. Immediately alter the reduction the 
joint was bathed in warm water to allay pain and tenderness ; 
subsequently when the joint became somewhat swollen and hot it 
was frequently bathed in cold water; when the inflammation had 
subsided a little oil of turpentine was rubbed about the joint. 
The cow is still lame, but is able to bear her weight on that limb ; 
it is rapidly improving. 
The writer begs to call attention to this case in order to draw 
from it a lesson. Here was a serious injury, such as would usually 
prompt the slaughter of an animal, oftentimes at great pecuniary
