results from suffocation. In more favourable instances, however, the 
engorgement subsides, the heart regains power, the circulation through the 
lungs is restored, and the aninjal soon regains its normal condition, 
In some instances, frothy blood is discharged through the nostrils owing 
to rupture of the engorged vessels of the lungs. : 
Except in very severe cases, the animals usually make a complete and 
‘comparatively rapid recovery. Acute congestion of the lungs, however, 
is very liable to recur for some time after apparent recovery, and is not 
unfrequently followed by acute inflammation of the lungs. Instances of 
death from acute congestion of the lungs have not unfrequently occurred 
within a few days of the purchase of a horse, and the changes found after 
death, which in some cases are of a very marked character in the lungs, have 
sometimes been ascribed by the uninformed to long standing diseases of 
these organs. On some occasions, indeed, the seller has, in consequence of 
this mistaken idea, been compelled to refund the full value paid for the 
animal. Yet these very features, which were attributed to old standing 
disease, are on the contrary the characteristic results of acute congestion. 
Indeed, the darkly coloured friable condition of the lungs, with the tendency 
to putrefaction and liquidity, so far from being the results of chronic disease, 
are in all cases characteristic of acuteness of attack. No doubt, in many 
cases, the purchaser of the animals, presuming them to be in a well-trained 
condition, forthwith puts them on trial, with the result that congestion of the 
lungs sets in severely, and the horses die. The writer had under his care a 
very severe case of pulmonary apoplexy or congestion. The animal was a 
very fat draught mare. The attendant had taken her for an unusually long 
journey, and, on arriving home, observed blood oozing from the nostrils of 
the animal, which was standing with outstretched limbs panting and gasping 
for breath. She, however, made a complete recovery in a few days. 
We will now turn to the consideration of the treatment of these cases, 
Of their prevention by careful training, and not putting animals to sudden 
unusual strains, we need not speak further here. 
In the treatment of acute congestion, it is imperative above all other 
things that the horse should have a plentiful supply of pure, fresh air; and 
strict quietude and repose should be enjoined in all cases. .. The body must 
be well rubbed down with wisps of straw, and afterwards warmly clad. The 
legs should be carefully bandaged with thick wool or flannel, being previously 
rubbed with some stimulating liniment. Internally, alcohol, in its various 
forms, in moderate and frequently repeated doses, is of great value in helping 
to restore the flagging circulation. From four to six ounces of brandy, with 
three ounces of liquor ammonii acetatis may be given at first, every two hours 
for three times, and then every four hours for about the same number of times. 
If the symptoms continue unrelieved after these steps have been taken, bleeding 
is necessary in order to relieve the congestion of the lungs and the engorgement 
of the great veins and right side of the heart, a consequence of the impeded 
circulation in the lungs. By this means impending suffocation is averted. 
From three to four quarts of blood may be withdrawn by the operator. It is
