We think our readers will perceive that this was not a case of confirmed intellectual degradation, but only of retarded mental development, the result of diseased bodily condition. These diseases are distressing to parents and friends, and he who succeeds in restoring them to health, intelligence, and the enjoyment of life, accomplishes a great and good work; but it does not necessarily follow that the cases where the mental degeneration is as complete as the physical would as readily yield to treatment; and we are driven to the conviction that the enthusiasm and zeal of Dr. Guggenbühl have led him to exaggerate the measure of success attained in these cases of low grade, and thus to excite hopes which could never be fulfilled.[A] [Footnote A: Dr. F. Kern, Superintendent of the Idiot School at Gohlis, near Leipzig, in an article in the _Allgemeine Zeitschrift für Psychiatrie_, published the present year, (1857,) states that he examined a boy in the Abendberg Hospital in 1853, of whom Dr. Guggenbühl had said, in his work _Upon the Cure of Cretinism_, published a few months previously, that, "after the painstaking examination of Dr. Naville, he was held to be capable of entering a training school for teachers, in order to qualify himself for a teacher": Dr. Kern found that he knew neither the day of the week or the mouth, nor his birthday, nor his age.] There are four other institutions in Germany devoted wholly or in part to the treatment of cretins; they are located at Bendorf, Mariaberg, Winterbach, and Hubertsburg. There are also two in Sardinia. All together they may contain three hundred children. The success of these institutions has not been equal to that of the Abendberg, although the teachers seem to have been faithful and patient. The statistics of the latest census of the countries of Central and Southern Europe render it certain that those countries contain from seventy-five to eighty thousand cretins, and as the cretin seldom passes his thirtieth year, the number under ten years of age must exceed thirty thousand. The provision for their training is, of course, entirely inadequate to their needs.
