242 ON HEPATITIS, TRACHEITIS, Scc, 
a-day; blister on the left side, and repeated on the right side 
and throat. 
Evening. —Pulse eighty-six ; respiration scarcely quicker than 
its natural state; the other symptoms much the same. 
Sd day. —Worse; pulse ninety-two, and exceedingly weak; 
dung harder ; urine increased, and frequently discharged ; mem¬ 
brane very yellow, and a dirty discharge appears from the nos¬ 
trils. 01. lini. sem. Ibj. aloes 3iss in haust.; fever balls repeated 
without the nitre; injections of warm water; blister repeated on 
sides and throat. 
Evening. —No better. 
4th day. —The same treatment was continued with some vari¬ 
ation, but the horse continued to get worse, and died during the 
night. The blisters had not risen in the slightest degree, though 
repeated once or twice every day. 
Fost-mortem appearances. —Liver quite yellow, and approach¬ 
ing to mortification ; its substance could be broken with the 
slightest touch. One of the lobes of the lungs was healthy, the 
other inflamed, and in part hepatized ; and a portion emphysema¬ 
tous. The mucous membrane of the larynx, trachea and bron- 
chiae was of a dark green colour, and one of the kidneys was also 
considerably inflamed. The horse, I understood, had been sub¬ 
ject to an occasional cough for some time past, and about a 
fortnight prior to his death had been ridden through some water. 
Hepatitis, I believe, has prevailed in some places to a great 
extent. I have seen but little of it myself; but, I understand, 
that the Third Dragoon Guards, whilst staying at Brighton, 
had a vast number ill with this disorder, and many died. 
This inflammation of the trachea, however, has been a very 
frequent complaint in this neighbourhood during the last win¬ 
ter and the previous autumn, and a more insidious and trou¬ 
blesome disease scarcely exists: its fatality probably arises from 
its deceitful nature, its appearance at first being so much like a 
common cough, for which no advice is resorted to, save that of 
the groom or blacksmith. A horse, perhaps, is observed to have 
a hard cough ; this cough increases, the appetite diminishes, but 
no discharge of mucus appears from the nostrils : the breathing 
becomes accelerated, but not oppressed, nor so quick as to alarm 
the attendants. In a few days the animal refuses his corn entire¬ 
ly, and it is thought better to seek professional assistance. The 
practitioner finds him in the above state; the extremities perhaps 
cold, or hot and cold alternately; pulse from sixty to seventy- 
five ; but is told that the cough is much better. The cough is 
probably much less frequent, and; in a day or two, ceases alto¬ 
gether ; but this, instead of being a good symptom, is one of the
