MR. YOUATt’s veterinary LECTURES, 
willing to work, he is easily tired ; sweating on the least exertion, 
and the sweat most profuse about the chest and sides: his ap¬ 
petite does not return, or perhaps it was never good, and the 
slightest extra-exertion puts him entirely off his feed. I observe 
him more attentively, and, even as he stands quiet in his stall, 
the flanks heave a little more laboriously than they should do, 
and that heaving is painfully quickened when he is in‘ exercise. 
He coughs now and then—sorely,—and discharges from the 
nose a mucus tinged with blood, or a fluid decidedly purulent; 
the breath becomes a little strong, and, by-and-by, very offen¬ 
sive ; while the pulse is always above forty, and strangely 
increased by the slightest exertion. 
When many of these symptoms are developed, the animal will 
exhibit considerable pain on being tapped, or gently struck, on 
some part of the chest; and then, all at once, the cough becomes 
more frequent and painful—the discharge from the nose more 
abundant and foetid—the emaciation, and consequent debility, 
more rapid, until death closes the scene. 
Post-mortem Appearances. —The lesions which are presented 
after death are very uncertain. Generally there are tubercles; 
sometimes very minute, at other times large; they are in different 
states of softening, and some of them have burst into the bron¬ 
chial passages, and exhibit abscesses of enormous size. Other 
portions of the lungs are shrunk, ffaccid, or indurated,—hepatized, 
—of a pale or a red-brown colour; and there are occasional ad¬ 
hesions between the pulmonary and costal pleurae. 
Symptoms when not connected with Acute Injiammation. —A 
other times there is no previous disease deserving of notice, but 
there is cough more or less frequent, dry, or accompanied by 
nasal discharge ; slight diminution of appetite, and that only 
apparent after unusual work ; want of perfect condition ; a de¬ 
gree of listlessness when not at work, but which immediately 
yields to ardour, scarcely perhaps to be restrained^ when the 
animal is exercised ; a little heaving of the flanks, and this only 
perceptible after exertion : and this will continue for months or 
even years, without any disease or apparent derangement that 
interferes with ordinary service and work. At times the horse 
will rally, the appetite will return, and the condition will im¬ 
prove; but this will last only a little while:—the cough will 
return from slight or unknown cause, and the listlessness, and 
want of appetite. Next will appear hectic fever, and the malady 
will run its fatal course. 
This is a meagre account, gentlemen, but it is the best I can 
give you. Our veterinary authors either mention it not, or 
bestow only a few lines on the consideration of it.
