The mucous membrane is swollen and bathed with a serous, sero-punilent, (n* purulent discharge, the character depending on the stage ofinflammation. The contractile tissue over the turbinated bones is con-gested and swollen. It feels elastic when touched with the probe, andshrinks when cocaine is applied. In chronic hi/pertrophic rJiinitis the uvula is thickened and elongated,on account of the hacking. The outer surface or the edges of the tur-binated bones are enlarged throughout or in localities. The mucous mem-brane covering these spots is thickened, hard, and rough. If cocaine isapplied, the mucous membrane does not contract, as in the swelling due. Rhinoscopic image. (Seiler. )1.

The posterior ends of the inferior or middle turbinatedbones are enormously enlarged, forming round tumors which obstructmore or less the posterior nares and project into the pharynx : polyps anddeviation of the septum may complicate these cases. The same appearances are seen in chronic post-nasal catarrh, and inaddition, a mammillated and thickened appearance of the pharyngealmucous membrane and that of the posterior third of the septum. In drycatarrh the mucous membrane is coated with mucus or covered withcrusts. In atrophic rhi
