    Fahlman's Impi'oved System of Disinfecting Foecal Matter. the letters of reference marked thereon:—Pig. 1 is an elevation of one arrangement of apparatus for enabling the foecal matter to he disinfected at the time of its production hy urine absorbed with disinfecting matter. The apparatus consists of a small vessel A for receiving the urine only . of the person using the privy or commode, which vessel communicates 5 with the excrement receptacle E hy means of the pipe B, C, D, the part B being descending, the part C rising, and the part D delivering. The apparatus is placed under the seat of the privy or commode in such a position that the urine cannot pass to the excrement receptacle E until it has passed through the pipe B, 0, E, and it is in the descending 10 part B that the disinfecting matter is placed, it being passed as powder crystals, or otherwise, through the hole at bottom of the vessel A. As the urine fills the parts B, 0, it dissolves and takes up disinfecting matter and afterwards runs off through the part D to the solid excre¬ ment, especially When a quantity of fresh urine is added to the 15 vessel A. Another arrangement shewn in the elevation, Eig. 2, consists in providing the vessel A which receives the urine with a vertical pipe B opening at the bottom into a box or reservoir 0, containing disinfecting matter, there being at the top of the box a delivery pipe E opening 20 into the excrement receptacle E. The pipe B conducts the urine to the bottom of the box G, from whence it rises through the disinfecting matter to run off through the delivery pipe E to the excrement deposited in the receptacle E, and hy this arrangement any obstruction in the passage of the urine is avoided, and the delivery pipe E, both in 25 Eigs. 1 and 2, can he passed round to the hack hy giving it the necessary length and curve. In some cases the disinfecting matter is placed in the box in such quantity that the urine, after having passed through it, shall have a certain depth above the disinfecting matter, and run off to the excrement, 30 when a fresh supply of urine is added. Eig. 3 represents in elevation a modification of Eig. 2. Instead of fixing the box B to the front wall of the seat, and thereby make both the box and vessel A stationary, I connect the box C and vessel A, Eig. 3 to a plate E, so that they can swing or turn to the position shewn 35 hy the dotted lines, in order that all the urine may pour in an instant into the excrement receptacle E. Eor this purpose the plate E is jointed to a bracket E^ fixed to the wall O of wood or masonry, and near the
