    Provisional Specification. A.D. 1868.—N° 2883. Hugharis Improvements in Treating and Deodorizing Sewage, 8fc. purpose is claimed. It must be used with water* the cement being in the same proportion as when mixed with sand for mortar; carbonic acid is formed by the setting process* and as this element is as essential to the life of plants as ammonia and as difficult for the plants to forage, this 5 ready presentation (in an available form) of carbonic acid must prove of material service to the growth of the plants, and therefore in the manu¬ facture of my manures from night soil and such like refuse matter by my system of cementation every encouragement will be given to the generation of carbonic acid by introducing peat charcoal and other 10 sources of carbon to be acted upon by salts and the creative principle of carbonic acid in the setting process of the cement. The carbonic acid may be said to be in a soluble state as found in the crushed down cemented night soil; and I claim the extension of this principle in all mortars and cements when set with water, and afterwards ground up into 15 powder for agricultural purposes. I also claim the direct absoption of acids by the setting process into cement for agricultural purposes, and more particularly the production of carbonic acid; and I further claim the use of carbonic acid as a manure in a direct, pure, or mixed form. I may add that when I use Portland cement in the cementation of 20 night soil and sewage I allow the set substance to remain in that form for a few weeks, until all feculent odour is absorbed before crushing into powder. Spontaneous cementation may be attempted by allowing the nightsoil or other matters treated to flow over or through the cement. 25 SPECIFICATION in pursuance of the conditions of the Letters Patent, filed by the said William Henry Hughan in the Great Seal Patent Office on the 17th March 1869.
