TREADS.

3. When over-work, or scanty or bad food, have reduced the 
system to a state of complete debility, we observe, all at once, 
a slight discharge from the nose, which increases in proportion 
to the degree of predisposition, or as the primitive constitution of 
the animal might predispose him to these fatal effects.

ON TREADS. 
Bij Mr, J. P. Cheetham, V.S., London. 
Among the accounts of the numerous cases recorded in your 
Journal, I do not recollect having seen any of the injuries arising 
from treads; allow me therefore to offer the following remarks :— 
The term tread is applied to all those injuries which are pro¬ 
duced by a horse treading upon and wounding the one foot with 
the other. In many instances these wounds are of trivial im¬ 
portance, while in other cases they are of material consequence. 
Dray-horses in London are most exposed to these acccidents, 
which are attributable generally to the incautious manner in 
which draymen turn round the corners of narrow streets. The 
horse most liable to the injury is the one in the shafts: he is 
nearly always literally dragged round by those in front, and in 
this act the poor animal is compelled by the weight of the load 
upon him, and the force of the other horses, to place his feet with 
an incautiousness which he would otherwise avoid, and, occasion¬ 
ally treading with one hind foot on the coronet of the other, 
a contusion or wound is the result. There may, perchance, be 
only a simple scratch, which will be of no consequence; or there 
may be a wound, or a separation of the parts about the coronet, 
which may be attended by serious effects : the coronary ligament, 
the intermediate soft parts, and even the bones themselves, arc 
sometimes implicated. In a case of this description, on theanimars 
arrival at the stable he frequently cannot bear his foot to come 
in contact with the ground: he is covered with ])erspiration; his 
pulse perhaps 100 in the minute ; and the respiration is augmented 
in an equal proportion. 
In such a case, all that is to be done in the first instance is 
to wash the foot with warm water, remove the shoe, immerse
