he exhibited great difficulty in breathing, which was ac¬ 
companied by a roaring sound so loud that the driver 
became alarmed and immediately took him back to his 
stable. 
In a few days after this occurrence he was harnessed once 
more for work, and was about to be led out of the stable- 
yard, when he suddenly fell, and, after a brief struggle, 
expired. 
Unfortunately the knacker neglected to preserve the 
trachea, as desired, and thus we were deprived of the oppor¬ 
tunity of ascertaining the precise condition of the tube. 
I have given this brief outline of the case because I 
consider it one of a very unusual character; indeed, one 
not mentioned, so far as I am aware, in any pathological 
work we are possessed of. Probably the gradual thickening 
of the trachea led to an insufficient supply of oxygen, so that 
the animal suffered from a similar change in the blood to that 
which is witnessed in cyanosis, and thus was produced the 
sudden death by asphyxia.
