be found that when it reaches the point indicated by the measure- 

 ment, instead of passing doivmvard into the pharynx, it glides 

 upward for a distance of two or three inches and stops against the 

 ethmoid bone. A common flexible horse-catheter would answer 

 the purpose well, but perhaps not so well as the metallic sound. 



The treatment is exceedingly simple, and consists merely in push- 

 ini)' the curved end of the metallic sound tliroua;h the membranous 

 partition, and then enlarging tlie opening, or an opening may be 

 made alongside of the septum nasi, just below tlie frontal sinuses, 

 and an ordinary pair of curved forceps of sufficient length passed 

 downward between the septum or vomer, striking the persistent 

 membrane almost at right angles and rendering its rupture and 

 laceration to any degree desired readily accomplished. Tlie removal 

 of the lacerated portions would i)e quite unnecessary.
