l._The nostril leading direct to 2.— The larynx, situated at the commencement of the windpipe. 3.— The 

 tongue. 4. — The oesophagus or gullet. 5. — The soft palate, which lies upon the tongue and affords a resting- 

 place whereon reposes the epiglottis, or the guardian cartilage to the entrance oJ the larynx (3). 6.— The 

 guttural pouches, or large membranous and open sacs, containing nothing but atmospheric air. 7.— Nasal or 

 trontal smuses. 8.— The false nostril. 



I. Tumor in the False Nostril. 

 The false nostril is the small pouch or cul de sac on the outer side of 



the lower edge of each nostril. Tumors are liable to form in these, and 

 partake more of the nature of abscesses, in 

 that they are filled with pus of a cheesy 

 consistency, but are tumors in that they 

 form slowly and do not point and break like an 

 abscess. They are usually about the size of a 

 hen's egg; they are not sore, but cause more or 

 less wheezing in the breathing on account of 

 the diminished capacity of the air passage. 



How to know it.— A small swelling will be 

 apparent on the outside, but the main depend- 

 ence is to be placed upon the examination of 

 the nostril, when it will be found to be nearly 



closed by the tumor in the false nostril.
