391' TUMOUR WITHIN THE WINDPIPE OF A HORSE. 
to the ordinary cause^ viz._, some obstruction to the natural 
respiratory functions situated in the larynx. In a day or two 
after he was sent away to he broken to harness^ but in a few 
days the breaker’^ noticed an enlargement in the neck and 
a difficulty of breathing when the animal was made to undergo . 
exertion; he therefore sent him home again, and on Monday, 
April 13th, we were sent for to see him. AVe found that the 
animal, when walked out, made a peculiar roaring noise during 
respiration, which there w'as now no difficulty in perceiving 
was caused by an enlargement existing half way down the 
neck, and obstructing the natural respiration. The case being 
an unusual one, and not being very certain as to the real 
nature of the disease we had to contend with, I suggested 
taking the animal to the Veterinary College for your opinion. 
To this the owner consented, and on the following day I pro¬ 
ceeded with the animal to the College. The enlargement and 
difficulty of breathing had increased during the night, and on 
the way from Euston Station to the College the horse had 
several severe fits of coughing. Your examination of him, 
you Avill remember, resulted in your giving an opinion that 
the obstruction, whatever it was, existed within the trachea, 
being in all probability situated between the tracheal muscle 
and the superior and posterior part of the trachea, and that the 
ultimate recovery of the animal was very doubtful. He was 
brought back to our stables the same night, and the treat¬ 
ment (viz., warm fomentations with alterative medicines) 
carried out for about a week. The animal continuing in much 
the same state, excepting that the enlargement slightly in¬ 
creased, more particularly on the left side, a blister was applied, 
and after remaining for another week Avith little alteration, 
Ave thought he might be remoA^ed to the OAvner^s stable, being 
situated but a short distance. On April 27th the groom 
proceeded to remove him, and during the journey he kicked 
and played about, showing hoAv little effect the disease had upon 
his general health. This, however, brought on violent coughing, 
and rendered the respiration so difficult as to quite alarm the 
groom. HoAvever, after being in the stable a short time, 
he quieted down, ate a mash, and appeared about the same 
as on several days preAnous. On the following morning, about 
nine o^clock, the groom came in haste to say that the horse Avas 
Avorse, and that unless something Avas done he would soon be 
dead. Mr. AValkor and I went immediatelAq and found the 
animal reeling and staggering about the box, Avith open mouth 
and distended nostrils, breathing with great difficulty (the in¬ 
spiration being long and the expiration very short), evidently 
suffering from impending suflheation. The only means of pro-
