I cannot help thinking, however, that the calculation sometimes made that the proportion of main 0. the patient receives is one-fifth, is too high.* * This is not an argument against the use of the electric bath in proper hands. The dipolar bath, with its painless—or at worst “ pleasantly painful ”— evenly-applied, and widely-distributed C., must ever be an admirable method of general electrization. That it is wasteful is not a serious drawback with plenty of battery power behind us—or still less so * In an original article, Lancet, March 28th, 1891, it is stated that “ it has been calculated that the proportion of C. the body receives is In the Text Book by Dr. Steavenson and Dr. Jones it is put down at I note with regret that in neither case is the calculation given by which the result is arrived at.
