CHAPTER V. METHODS FOR THE MEDICAL EMPLOYMENT OP ELECTRICITY. Alcre jlammam vitalem. Precautions. First of all, it is necessary to bear in mind that there is the greatest conceivable difference in individuals of the same age and sex as to their susceptibility to the effects of all electric cur- rents ; and these form two classes of patients. The first are those where there is exalted sensibility, and where only the most gentle procedure, and that with the most feeble currents, is at all admissible. In this class we may also include those with exquisite susceptibility to the in-working- and also reflex action of the current, and that without their suffering, or even scarcely noticing it, during the seance. See pp. 475-479 & Notes in App. The second class of persons are those where there is neither anaesthesia or paralysis, and yet there is a very marked indiffer- ence to the attempts of the currents. Some do not feel even the stronger currents; and others do not receive, or rather give no evidence of receiving, any impression from their in-working. For such reasons, great precaution is necessary in the employment of electric currents, particularly in giving the first seance for a new patient, until we study the temperament; even then we cannot
