    laston ; and the result occasionally produced by direct or indirect injury; thus, for example A Gentleman, in consequence of a fall from his horse about four years ago, received a violent blow, which produced concussion of the brain, and gene- ral ecchymosis on that side of the head; which symptoms having continued for a few days, gra- dually subsided, without evidences of inflammation, or lesion of any kind, but he has ever since con- tinued perfectly deaf on that ear. Upon examin- ation the Author can discover no cause for the loss of function; the auditory meatus and membrana tympani possess normal appearances; the Eusta- chian tube is pervious and otherwise healthy; readily admitting the injection of air and of water into the tympanum, which strike audibly against the membrane: the ticking of the watch is distinctly heard when placed in contact with the head, face, teeth, or with the ear; but when held close to the auricle without being allowed to touch it, the sound is quite inaudible. As the labyrinth performs its function, it is a fair presumption that the disorder is confined to the tympanum.—May not a torpid con- dition of the tympanic nerves exist ? or, is it pos- sible that a displacement of the ossicula may be occasioned by the injury received ?
