Sternutatory medicines have often been recom- mended as a remedy for deafness, but for fulfilling the same intention the probe will be found far more effi- cient.- Its effects are somewhat different, though both, in appropriate cases, stimulate the nasal mucous mem- brane to a healthy action; but the elastic probe is in- finitely superior, because it mechanically dilates the contracted passages, and does not rob the mucous sur- faces of the natural secretion which is necessary for their healthy condition, but of which sneezing tends to deprive them. It will not be out of place to remark that the habitual use of errhines, especially the common snuffs, have sometimes the effect of producing chronic engorge- ment of the mucous membrane of the nose, and thus occasion injury to the hearing and other functions. In some individuals the septum narium is inclined so much to one side, without any external disfigure- ment, that it is impossible to breathe, or to pass the probe, through the contracted aperture. Where this is the case, the operation should never be attempted; and there is rarely any cause for it in cases of this kind, because of the increased size of the opposite passage. There are other cases, however, in which the nostrils and nasal canals are congenitally of small size, where the elastic probe, or any instrument capable of gradu- ally dilating them, will be very beneficial. Of this kind was the case of a nobleman, whose nares were so small that the passage of the Eustachian catheter, in Paris, by Deleau (a very experienced operator), occa- sioned much pain; but the careful performance of the
