assist in respiration, and would thereby greatly increase his di 
tress. There is occasionally cough, and usually a total loss 
appetite, with increased redness of the conjunctiva, and a led I 
livid appearance of the pituitary membrane. The countenan! 
pourtrays extreme anxiety, and manifestly evinces great suffit 
ing, and, as Mr. William Percivall says, almost seems to appn 
to us for relief. . 
The terminations of Peripneumony are very uncertain, both 
it regards time and manner. A horse may be attached w 
acuteT inflammation of the lungs and die in twenty or twenty-f< 
hours, or he may live as many days and then die, but the p 
mortem appearances in these cases will be very difleient. InII 
first we should find the lungs completely distenued, and goigl 
with blood of a dark venous colour; and, in the second, 
should find numerous adhesions of the lungs, with effusion o: 
considerable (quantity of serous fluid in the cavity of the cht 
In both cases death is produced by suffocation. Theie aie a 
other terminations, such as suppuration; or there may be an ef 
sion of lymph in the air-cells, producing thick wind, and t 
may ultimately terminate in broken wind; or the suppurat 
process may go so far as to destroy part of the substance of 
fungs, and cause death by the great emaciation that ensues: 
may also terminate in mortification. The usual time at wh 
we may calculate that this disease proves fatal, is at the exp: 
tion of three or four days, or from that to a w r eek, unless effus 
takes place, and then the termination, with very few exceptic 
is protracted to three or even four weeks. 
If, at the end of the second or third day from the time 
the commencement of this malady, the treatment adopted is jj 
ductive of a remission of the symptoms, such as the breath 
becoming more tranquil, the pulse less frequent, the extremi 
gettin 0 ’ warm, and the countenance less expiessive of pain, 
prognosis is favourable, and our patient will probably soon be c 
valescent; but if the symptoms continue unabated, and 
external stimulants, as rowels, blisters, &c. have little or 
effect, there is not much chance of recovery. 
There is yet another termination of this disease, viz. in r 
lution. And this, I might almost say, is the only favour: 
termination: the lungs resume their natural functions witt 
any alteration of structure, or, rather, without any morbid < 
sequences being left; while the other terminations, if they doJ 
destroy life, so impair the structure of the lungs, that the v 
of the animal is greatly deteriorated, and his utility consider:*
