A room forty-five feet long and twenty broad, with a vaulted ceiling twenty feet high at the crown, is provided along each of its two longer sides with a series of marble slabs rising in three tiers from eighteen inches above the floor to a couple of feet below the ceiling. The idea may be gained more accurately by supposing three steps of a giant staircase mounting from an aisle three feet wide through the middle of the room, back and upward to the parallel cornice. The level surface of each of these steps is sufficiently wide to accommodate a man stretched on his back, and the upright portion of each step is an iron grating. Under the series of steps on both sides runs a system of sinuous iron pipes pierced with minute holes, and connected by stop-cocks with a boiler out of sight. The steps occupy in length twenty-five feet of the room, and its entire breadth except the narrow aisle between the is occupied by a tank sunk beneath the floor, sixteen feet square by four and a half deep, filled with water kept throughout the year at a uniform temperature of about 70° F., and by the gallery which runs round the railing of the tank on the floor level. About the sides of the gallery are arranged hot and cold water-pipes with faucets and hose connections, the hose being terminated by a spray apparatus similar to the nose of a watering-pot. Opening off the gallery at the end furthest from the steps is a small closet fitted up with ascending, descending, and horizontal shower apparatus, by means of perforated plates connecting with the water-pipes by faucets set in floor, walls, and ceiling. After the battery, the capsicum, and the nux, if Mr. Edgerton can retain it, we feed him by slow tea-spoonfuls from one-half to a whole cup of the most concentrated beef-tea--prepared after Lieblg's recipe or another which I have usually found better relished, and as that, where food must be administered to fastidious stomachs, is half the battle, which I prefer. (I will give it hereafter.) Should his stomach reject it thus administered, it must be given as an enema. Its place in the plan of all enlightened medical treatment is too lofty to need my insisting on. We must rely on it at Lord's Island every step of our way. It will not have been within our patient's system five minutes before the pulse shows it, nor ten before he feels from head to foot as if he had taken some powerful and generous stimulant. It is always wise to give beef-tea, even just before a bath of any kind, and it is never well to enter the Russian bath on an empty stomach.
