The first court has the most pleasing appearance, the arcades render it light and elegant, and although ornamented with figures, arms, horses, and trophies, they are not exuberant, and its simplicity is not deteriorated. The church is a most magnificent structure, presenting an extraordinary mixture of military and religious decorations. The dome, which has an effect truly noble, is adorned by paintings of the twelve Apostles by Jouvenet, surmounted by a glory from the pencil of Lafosse, with a beautiful tesselated pavement beneath; there are some other good paintings, but many very bad. The gilding, although extremely gorgeous, harmonises well with the varied colouring which prevails throughout this beautiful edifice, and has not a gaudy appearance. There are monuments of several of the governors of the hospital; numbers of portraits, and banners taken from different countries, which amounted to as many as 3,000, but on the evening prior to the allies entering Paris, Joseph Bonaparte ordered them to be burnt. To give any thing like a comprehensive idea of this wonderful building, would require many pages, there is such an immense number of interesting objects, the description of which would compel the omission of other matter equally important; but, whether taken for its exterior or its interior, it certainly is one of the grandest monuments extant. The approaches to it are particularly fine, being by long vistas of high trees, with a most noble esplanade in front. A library belongs to the establishment which was founded by Napoleon; it consists of 30,000 volumes, and his portrait by Ingres is one of its valuable ornaments. It is gratifying to see so many of the Invalids constantly in the library, amusing themselves with reading; it is a pleasing sight to be there at meal-time to witness the cleanliness and comfort which prevails. Besides board and lodging, every soldier receives 2 francs a month, and officers and non-commissioned officers in proportion; 5,000 is the number the establishment can contain.
