TRACHEAL POLYPI.

these lesions were caused by her throwing herself down, or 
from the violence of her throes, I know not ; all I can say is, 
that I never remember an animal exert the force to expel the 
foal that she did for a short time. Nothing in the sha 
an instrument was used by me, which I was v

TRACHEAL POLYPI. 
By Gr. Fleming, Y.S., 5th Battalion, Militar 
Believing the occurrence of polypi in the air-passages, 
from the larynx downwards, to be somewhat rare, I take the 
liberty of forwarding you for insertion the following account 
of a case that lately came under my notice : 
A brown horse — one of a number transferred to this, from 
another battalion, whilst at Aldershott, was, immediately upon 
his arrival, found to be incapable of performing his duties, 
in consequence of a remarkable difficulty he had in breath-, 
ing, altogether different from that usually manifested by 
roarers . 
The only information I could obtain of his previous history 
was, that a long time ago he had shown symptoms of 
pneumonia, for which he had been treated, but that he had 
only partially recovered, as he was always, from that time, 
easily distressed by work, and coughed a great deal on being 
taken from the stable into the cold air, and vice versa . 
On the 4th of April, I had an opportunity of examining 
him carefully, and the very first observation made by me 
indicated some obstruction in the air-passages, as, when 
standing quietly in the stable, he could be heard breathing 
some yards off; and on the least active exertion, moving even 
a few paces at a walk, the respirations became hurried and 
laboured, the countenance betrayed anxiety and distress, and 
a shrill, whistling sound was heard, louder in expiration than 
in inspiration. When changed from a hot to a cold place, 
or from a cold to a hot one, he was immediately seized with 
a violent, dry, husky cough, which threatened to suffo- 
cate him. 
Auscultation revealed, behind the scapulae, exaggerated 
bronchial, and very faint, indistinct, vesicular respiratory 
sounds. At the point of the sternum, and from thence to the 
middle third of the trachea, this sound was much increased.
