Thus, bleeding among the deaf should be resorted to as seldom as possible; nay, it should never be practised unless under circumstances of the most pressing neces- sity. The deaf are invariably rendered worse as regards the hearing, except when acute disease of the ear exists, and even then local bleedings are sufficient to subdue inflammatory action. Dr. Marshall Hall has shown that deafness is one of the sequelae of loss of blood, even when performed on those in the full pos- session of the auditory sense. It has also been found, in experiments on dogs and other animals, that exces- sive bleeding is followed by the loss of both sight and hearing. It is a remarkable fact, that pregnancy, which gene- rally stays the progress of other maladies, very often increases those of the ear. If deaf persons, as is some- times the case, improve during the period of gestation, it generally happens that they become worse after their confinement. Deaf women frequently become much worse during the period of lying-in, and on this account require more care than usual to recover them from the shock of labour and the consequent debility. With attention, they often recover at least their former state of hearing; but it must be borne in mind by deaf persons, that anything like prolonged lactation deeply injures their already delicate organ. According to much experience on this point, any ground lost during the period of suckling, by the deaf, is with difficulty regained. Drastic aperients and other depletory measures act in a manner similar to bleeding, and should therefore I
