Materia Medica

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.
