Long after the salivary glands have ceased to be affected, an erythematic state of the throat and fauces remains, often by its persistence affecting the Eustachian tube and tympanum in the manner I have described, when chronic catarrh has been the exciting cause. It may be argued, that when deafness follows a mercurial course directed against syphilis, the syphilitic disease is quite as likely as salivation to be the cause of deafness. Syphilis may, in some cases, be the chief agent in producing deafness; but I believe the great anti-syphilitic given in excess to be ten times more pre- judicial, because I have seen so many instances where this medicine was introduced under other circumstances, and even ill-advisedly as a curative agent in incipient deafness, with the same results. I might multiply cases in which this has happened, and where patients themselves confidently referred the aural malady to this cause. One case, of a very decided nature, I some time ago attended. It was a patient who was recommended by Sir Benjamin Brodie to consult a gentleman cele- brated for his treatment of a local disease from which he suffered, and which was cured by a mercurial course, but at the expense of producing a deafness which is now altogether irremediable.
