Errhines

poceed [proceed] from cold and from fevers when there is a congestion of blood in the brain. I believe it to be owing to an increased sensibility in the organ of hearing, it is I think curable, Blisters applied to the Mastoid Process, cupping, and bleeding from the arm, Purgatives and flannel nightcaps are all verry usefull. In this species of deafness Linneus thought the Errhines more usefull than anything else. In Gutta Serena they have been found often usefull, this is frequently an incurable disease and is proved by dissection to be sometimes owing to tumors pressing upon the brain and optic neves [nerves]. Mr Ware in this disease has used a stimulus of a Mercurial Nature composed of X grs. [10 grains] turbith Mineral and I have employ’d this and found it usefull in one case, in another in which it had a fair trial it did no good. It would seem these remidies were applicable to particular cases, where the disease depends on Syphalis no dependence is to be placed on Errhines. But in some species which he calls Amaurosis Plethora, in which he said the errhines did good, this kind of Gutta Serena arises from the suppression of the menses sometimes, and sometimes appears in pregnant women.
