CASES OF CROUPAL ANGINA. 
At six o’clock we remarked very great increased sensibility ot 
the larynx; the mare particularly could scarcely bear it to be 
touched. The cough was frequent, by fits, and very painful; 
and the breathing was also painful. We could hear the whiz¬ 
zing in the larynx, accompanied by a kind of gurgling sound all 
along the windpipe, and stronger in the mare than in the horse : 
the same discharge from the nostrils that had been observed at 
first in the mare was now seen in him ; the pulse was unchanged 
in both of them; the eyes were clear and fixed, starting, as it 
were, from their sockets ; while tears ran plentifully down their 
cheeks. 
At half past six o’clock I repeated the bleeding, and took nine 
pounds from each. I ordered that the nostrils should be frequent¬ 
ly washed with warm water, and the unguentum populeum ap¬ 
plied to the larynx, which should be wrapped in flannel. 
Between eight and nine o’clock the mare seemed to suffer 
some colicky pains; she looked at her flanks; she appeared to 
be preparing to lie down, but did not dare to accomplish it. 
These symptoms were followed, all at once, by frequent evacua¬ 
tions of liquid faeces, black, foetid, and accompanied by flocculi 
of albuminous matter. 
At four in the afternoon all the symptoms were increased in 
intensity. The breathing of the mare was particularly hoarse 
and loud; but it was more painful, because that the humour 
which had run from her nostrils had become so thickened, that 
it had taken the form and organization of a false membrane, 
that covered the whole of the nasal cavities, and obliterated 
the natural openings. The portions which we could detach by 
means of the fingers, or by injections of cold water a little acidu¬ 
lated, or when the head was slightly shaken, were very large, of 
a deep yellow colour, and with a smoky smell. The pulse was 
a little accelerated; liquid fseces were discharged from time to 
time. 
The discharge from the nose of the horse had not changed its 
appearance; in fact, there had been no change of symptoms in 
him since six o’clock in the morning. 
I attempted to bleed from the jugular a third time, but could 
only obtain about six pounds of blood. I persisted in the treat¬ 
ment which I had adopted. 
23d.—The breathing of the mare was more free; she had 
ejected a great part of the false membranes that existed in the 
nasal cavities. 
24th.—At four o’clock in the morning the assistant farrier, 
who had set up with these horses, brought to me a portion of 
false membrane, of a deep yellow colour, like that which had 
been already ejected. It was four inches long, more than three
