    Legrass Improvements in the Manufacture of Manure. discharged into the vessel D, and fall through the opening F into their receiver by causing the valve B to open. This is effected by pushing down or pulling up the handle Z of the rod C, which is connected to one end of a shaft I, to which there is pivoted an oscillating lever H connected to the valve B. When the handle is released the counterbalance weight G comes into play, and 5 depresses the end of the lever H, thereby raising the valve B and closing the opening of the basin K. The valve B is hollow and is fitted with a pipe which passes through a slot into the pipe E, and the face of the valve B is perforated to allow of the escape of whatever portion of liquid may not have passed through the holes in the basin K to the liquid reservoir. This apparatus 10 consists of two parts bolted or riveted together at the line X, and is provided with any of the arrangements before described for discharging disinfecting agents in the form of a liquid or powder on to the surface of the solid fecal matters. Figure 15 is a sectional elevation of a modification of the construction and arrangement of watercloset last described, and differs only in the external 15 configuration, which is round instead of rectangular, and in the mode of working the valve. The step Z is substituted for the handle in the former case, and is attached to one end of a lever C, centred on the pin W, which is con¬ nected at the other end to the rod C1, attached to the shaft I and valve spindle II. By depressing the step Z the rod C1 and the end of the valve 20 spindle H near to it will be elevated, and the valve B be thereby tlirowm open. The same movement also works the powder box by means of the chain z1. Figure 16 (a sectional elevation), and Figure 17 (a top plan), represent a portable watercloset, constructed according to my Invention, for the separation of liquids from the solids of fecal substances. E is the step. D the side 05 opening, through which the liquids’ and solids’ receivers are introduced and withdrawn when required. IT is the pan, made of china or glazed earthenware. I, the opening in the bottom of the pan. B is the cover, to which there is attached a vessel or box K for containing the disinfecting agent. A is an opening in the cover B for introducing the disinfecting agent into the vessel K, 30 which may be stopped up when required. L is a pipe which opens at top into the vessel K, and at bottom into the pan as shewn in the Drawing, whereby, on lifting the cover B, a portion of the disinfecting agent will be discharged through it into the pan H. J is a pulley, round which passes a chain Q attached at top to the cover B and at the other end to the sliding piece N, 35 which will be drawn over and close the opening I of the pan when the cover B is lifted up. The solids and liquids are received upon the sliding piece N. The former remain and the latter run off down the outsides of the vessel R into the gutter S, whence they pass into the appropriate reservoir X when the chain
