    Manning's Improvements in Treating Foecal Matters. nature of the said Invention, and in what manner the same was to he performed, and cause the same to he filed in the Great Seal Patent Office within six calendar months next and immediately after the date of the said Letters Patent. 5 NOW KNOW YE, that I, the said James Alexander Manning, do hereby declare the nature of the said Invention, and in what manner the same is to be performed, to be particularly described and ascertained in and by the following statement thereof, and the Drawings therein referred to (that is to say):— 10 This Invention relates partly to improvements in the process for the treatment of foecal matters and the waste of towns, for which Letters Patent were granted to me on or about the 26th of July 1869, No. 2269, parts of which improvements are applicable to other manufacturing purposes. 15 In the Specification of my said Patent provision was made for the utilization of the carburetted hydrogen gas evolved during the combustion of the coal employed in the manufacture of manure, for lighting the factory or for illuminating purposes generally, but owing to the large amount of atmospheric air with which the said gas is combined as it 20 passes from the condensing tank into the gas holder, unless it be napthalized, it would but ill fulfil the required purposes. Now I propose, according to my present Invention, to utilize such gas for another purpose, by which »a great economy of coal, labour, and the cost of construction, may be achieved. 25 By my said process, as specified under the said Patent of 1869, I proposed to evaporate to dryness the solid and the fluid collections of the foecal matters of towns, and amongst other things I proposed to quicken the boiling of the excreta) in my fire-brick evaporating chamber by means of a coal furnace under the bottom or inverted arch of the said 30 chamber, with cylindrical fire-brick flues, conveying the heat, gases, and smoke from such furnace under the whole length thereof, and returning the same by side flues of a similar construction along the sides of the said chamber, discharging the heat, smoke, and gases into the interior of the chamber from which they were withdrawn or exhausted in combina- 35 tion with vapor, and discharged into the condensing tank by an exhaust and discharge fan situate at the opposite extremity of the long fire-brick evaporating chamber in question \ I now find that instead of employing
