266 SYSTEMS OF TREATING STAMMERING cost of considerable labor managed to communicate with a hundred ex-pupils of two other stammering- schools — one an American and the other an English institution, and both of them schools that guaran- tee to cure stammering.1 Among these one hundred ex-pupils, five pronounced themselves cured. Of these five students, two have, to the writer's knowledge, since relapsed. One of the remaining three the writer met recently in New York, and this cured stammerer was beating time and speaking at the rate of approximately one word a minute. Of the remain- ing two, one was a school-teacher before he attended the institution. Thus we have apparently two per- manent cures in one hundred cases, with one of the cures to be heavily discounted. This percentage is not in any way exceptional. The principal of one of the foremost Swiss institutions has recently abandoned his work because he was unable to cure more than four or five per cent of his cases. •*• Temporary "cures," or apparent cures, are easy enough to accomplish. Dr. Coen reported 54 cures in 128 cases. (Of the remaining patients, 52 were improved, and 22 not benefited.) Dr. Klencke, with 148 patients, admits failure in only 10 instances. But the "cured" patients referred to in these re- ports are merely pupils pronounced cured at the time 1 The majority of the correspondents attended the American school.
