PARTIAL OCCLUSION OF THE TRACHEA IN AN 
ENTIRE HORSE. 
By John D. Overed, M.R.C.V.S., Blofield, Norfolk. 
I have this day, December 13th, 1869, forwarded to the 
Royal Yeterinary College, per railway, a portion of the 
trachea of a horse which died on Saturday last, under what I 
believe very unusual circumstances. I subjoin a brief his- 
tory of the case for publication in the Veterinarian , thinking 
that perchance it may interest some of the members of the 
profession, particularly the junior portion. 
The subject of this disease was a valuable entire cart-horse 
rising six years old, which had frequently been a competitor 
at agricultural shows. My attention was first called to him 
on the 16th of August last, when I found him to be suffer- 
ing from a severe attack of bronchitis, accompanied with 
haemoptysis. Under the treatment employed, he gradually 
improved, and was discharged in about a fortnight from the 
sick list, hot, however, without being still affected with 
troublesome cough which continued several weeks. Recently 
he had shown, and especially when put to hard work, symp- 
toms of difficult respiration, accompanied at times with much 
distress ; but this was not much heeded by his owner, as he 
fed well, and appeared otherwise to be in perfect health. 
About a month since, however, the case assumed a more 
serious aspect, and my attendance was again requested. The 
horse was at this time suffering from extreme dyspnoea of 
of an intermittent character, the paroxysms sometimes last- 
ing only a few minutes, and recurring again and again after 
the lapse of some hours. In the intervals he appeared to be 
in health, his appetite and spirits being remarkably good. 
At the end of a week these symptoms disappeared, and he 
again became convalescent. On the 9th, I was again sum- 
moned in haste to see him, as he was said to be even worse 
than before, which I found, on my arrival, to be no exagge- 
rated statement. So urgent indeed were the symptoms, that 
I dare not exhibit any medicine, but recommended that re- 
course should at once be had to the operation of tracheotomy. 
To this proposal the owner — for special reasons — had an in- 
superable objection, preferring to risk the case rather than 
have recourse to the operation. The paroxysm lasted about 
twenty minutes, after which I gave a draught composed of 
the following —
