ASPIRATION PNEUMONIA FOLLOWING- ABSCESS OF STENo’s DUCT. 41 
closer examination of the body revealed a small swelling- on 
the left cheek. 
This rapidly sped downwards towards the nostril and 
soon infiltrated likewise the deeper tissues below the eye of 
that side. The lachrymal duct became obstructed, and the 
usual symptoms attending such a condition supervened. 
Further, there was considerable exophthalmous developed, 
the eye protruding from the socket to an abnormally great 
distance, and the conjunctiva was both injected and swollen. 
After several days the animal refused food, emaciated rapidly, 
while the swelling gradually increased in size. Hot fomenta¬ 
tions were applied, with a stimulating liniment, though with 
little effect. This condition persisted for about three weeks; 
and, actimomycosis being suspected, some of the pus was re¬ 
moved and examined at the McGill Pathological Laboratory 
for the fungus, though only with negative result. The secre¬ 
tions of milk had almost ceased, though the condition of the 
animal remained about the same. At the end of about the 
third week, signs of fever developed, and were accompanied 
by chills, weakened pulse, and foetid breath, depression and 
drowsiness, with diarrhoea. These symptoms progressively 
increased during the next three days, at the end of which 
time the animal died. This was nearly four weeks after the 
outset of the local symptoms. 
The post mortem showed a large abscess in Steno’s duct, 
containing about three ounces of yellow, creamy pus, and the 
surrounding tissues were softened and necrosed. Multiple 
abscesses were present in the lungs, and were surrounded by 
consolidated areas. Some of the abscesses were of long 
standing, in which the pus had dried up—in others the pus 
was fresher. In all cases the suppuration was connected with 
the bronchii, which in many places were dilated and thus pro¬ 
duced bronchi-ectatic cavities. Here, then, we have a case of 
aspiration pneumonia, septic germs being drawn in by inspir¬ 
ation from the abscess in the mouth and setting up secondary 
abscesses in the lungs, and a consequent pneumonia. 
There were no other signs of septic infection to account 
for the condition of the lungs, and the cause of death was
