DISEASES OF RESPIRATORY PASSAGES AND ORGANS. 10) 
him. Since the operation, LEBLANC had not observed any 
change in the horse, except a depression of the bones of the face. 
After death, the larynx was found very narrow, the mucous mem- 
brane and submucous cellular tissues were thickened, the epiglot- 
tis deformed, very obtuse, and everted at its free margin. The 
vnanges in the larynx were the original cause of roaring. The 
depression of the bones of the face was connected with constric- 
tion of the nasal chambers, and was evidently secondary to the 
change in the course of the air in the process of respiration. The 
parte of the trachea in contact with the tube had undergone a 
transformation into very hard tissue. It filled the trachea above 
the point where the tube had been introduced, and intermixed 
witl this firm fibrous deposit was a cartilaginous and osseous tissue, 
which offered great resistance to the scalpel. Roaring, thick wind, 
whistling, etc., are often the sequel of strangles, influenza, laryn- 
gitis, and other attectious of the respiratory passages, and henve 
hive an accidental origin. In such cases, we may entertain a hope 
of doing some good by means of medicinal agents and counter- 
irritation.

PoLYPUS WITHIN THE NosTRILS. 
Polypus is tle name given to an excrescence, or tumor, which 
as its origin from the surface of the membrane lining the nasat 
cavities. It is designated as growing from a mucous membrane, 
having a narrow neck and body, resembling, in shape, a pear. 
The usual symptoms attending the presence of polypus in the nasal 
cavities are as follows: Difficulty of breathing, evidently occasioned 
by obstruction in the air-passages.
