Sometimes it lias to be persisted in over a long period on account of a marked tendency to relapse. One case referred to me by Dr. Rager which had resisted all of the usual routine treatment improved rapidly under three applications a week of the high frequency current in connection with the high candle power light. Over sixty treatments were given, however, before the case was essentially cured. Fox treated 100 cases with no failures. The technique which I employ is as follows: I use the electrode shown in Fig. 21, No. 11. with just enough current to produce a stinging sensa- tion when applied to my own eyelid. The fine spark from it being from one-thirty-second to one- sixteenth of an inch in length. I raise the upper lid by pressure with the thumb and apply this fine spark along the edge for two minutes and then pull the lower lid down and do the same. Then while the patient closes the eye, I pass the elec- trode over the whole surface of the lids for two or
