2. The _healthy_ children of the _little school_, all of whom are able to walk alone. These undergo treatment for uncleanly habits. Special chairs are kept for the dirty, who are placed at stated times upon conveniences in order to regularise their functions. Then come _strengthening exercises_, which are gymnastics of a very simple kind; _toilet lessons_ to teach them to wash themselves; _table lessons_, to teach them to feed themselves, with spoon, fork, and even knife; the _training of the senses_; and, lastly, _training in speech_. 3. The third group includes children in the _big school_. These are less defective than the preceding. They are fit and healthy. But, on the other hand, there are found here a great many abnormal children (perverse and ill-balanced) who are not wanting in intelligence. The big school includes four classes, each under the charge of a professor. The education, especially in the last class, is carried pretty far, and many of the pupils possess their certificate of study. For reasons upon which we will not insist, we were not so delighted with the hospital of Bicêtre as we had been with the Salpêtrière. We might have dispensed with this visit. The medical superintendent of the school for defectives at Bicêtre has taken the trouble for a long time to publish regularly every year a volume of several hundred pages, which contains the most diverse statistical information about everything that goes on. We have studied the volumes bearing upon four years only--the years 1899, 1901, 1902, and 1903. Moreover, we profess that we have some knowledge of the school at Bicêtre, having not only joined several times in the Saturday visits, but having on several occasions carried on there researches in cephalometry; and, in the last place, we have had the pleasure of following in their inspection two members of the ministerial commission, who had had the idea of finding out how the teachers in the big school were fulfilling their functions.
