Charenton receives about 600 patients, 300 men and 300 women; but the number would be much larger were there sufficient accommodation. The terms for the paying patients are 1,500 francs for the first class, 1,200 for the second, and 900 for the third, while for those who have a separate room 900 francs extra, as the wages of a servant, are charged. Needless to add that the patients, paying or non-paying, are all on an equality as regards medical treatment. The quality and variety of the cooking vary with the different classes. The chief elements of the population of Charenton are furnished by officials and clerks, artists and men of letters, merchants, dealers in wine and spirits, officers and soldiers. Every type of madness may there be studied, from dementia and melancholia to mania. Many of the patients owe their malady to hereditary predisposition, alcoholic excesses, and other abuses, domestic calamities, reverses of fortune, and intellectual labour unduly prolonged. [Illustration: THE BIÈVRE.] Nothing is spared to provide the patients with salutary occupations, agreeable pastimes, and innocent amusements. They are encouraged to study music, singing, and drawing, and for those who have no artistic tastes, cards, draughts, dominoes, billiards, and bowls are provided. Among the outdoor recreations walks in the most beautiful parts of the wood of Vincennes, carriage excursions and picnics may be mentioned. The Thursday and Sunday concerts form, however, the great delight of the place. These are not given by the director simply as entertainments. They are prescribed by the regulations, and have formed part of the institutions of the House since 1811. In the spacious hall, which serves at once as ball-room and concert-room, assemble upwards of a hundred convalescents of both sexes. In the dress and demeanour of those present there is nothing remarkable, except that they are more quietly attired, and generally better behaved than in fashionable society. The billiard-room is much frequented, and the general aspect of the card-room reminds Dr. Linas of one of the aristocratic Paris clubs. It should have been mentioned that at the periodical concerts the music is contributed by the patients, some of whom are singers, others violinists or pianists. The officials of the establishment join the inmates either as performers or among the audience. In like manner the patients and attendants act together in the comedies and dramas which are sometimes represented.
