The limited experience of the few institutions already established warrants, we think, the conclusion, that too high expectations have been raised in regard to the complete cure of cretinism; that only a small proportion (cases in which the bodily disease is the principal difficulty, and the mental deterioration slight) can be perfectly cured; but that these institutions, regarded as hospitals for the treatment and training of cretins, are in the highest degree important and beneficial; and that, under proper care and medication, the physical symptoms of the disease may be greatly diminished and in many cases entirely eradicated, and the mental condition so far improved, that the patient shall be able, under proper direction, to support himself wholly or in part by his own labor. The hideous and repulsive condition of the body can be cured; the mental deformity will yield less readily; yet in some instances this, too, may disappear, and the cretin take his place with his fellow-men. Let us now turn our attention to another class, in whom, as a people, we have a deeper interest; for though cretinism does undoubtedly exist in the United States, yet the cases are but few; while idiocy is fearfully prevalent throughout the country. The possibility of improving the condition of the idiot is one of those discoveries which will make the nineteenth century remarkable in the annals of the future for its philanthropic spirit. Idiots have existed in all ages, and have commonly vegetated through life in utter wretchedness and degrading filth, concealed from public view.
