    Fenton's Improvements in the Purification and Utilization of Sewage, fyc. mixed with any of the compositions described in the said Specification or otherwise) a current or blast of atmospheric air, such current or blast being produced by any convenient mechanical means, and I also propose to apply the same for the extraction of “ magma,” “ seak,” or 5 grease from suds or other waters in which they may be contained in conjunction with the processes described in the Specification above referred to. After the extraction of the “ magma,” or “ seak,” or grease from any waters containing them by the processes described in the Specification 10 before named above, or by soda or salts of soda, potash or salts of potash, with lime or a solution of them or any of them, or by a solution of the compositions mentioned in the said Specification, I propose to use the same for the manufacture of soap by any ordinary or well known process of soap making direct without the necessity of first extracting 15 or pressing out the pure grease from such “magma,” “seak,” or grease (as hitherto practised)'either with or without an admixture of fresh grease, tallow, fat, or oil thereto. I find that it makes a better soap capable of forming a stronger lather if the soda or potash or other alkali used in the soap making is added to the magma, seak, or 20 grease in a dry powdered state, and also by the omission in the soap making process of the salt or lime water usually employed, and the soap is further improved by the use of chlorine in a solid gaseous or liquid solution state to the “ magma,” “ seak,” or grease, especially if the same is rendered impure by the intermixture of flocks, wool, hair, or 25 dye matters and maccerating or boiling of the whole together and the after application of alkaline hyposulphates or hyposulphites to destroy the chlorine after it has effected its purpose. And I also use “ magma,” “ seak,” or grease which has been obtained from such waters or refuse by the common process of extraction by the use of acids or acid salts 30 for the manufacture of soap direct, either with or without the admixture of fresh grease, tallow, or oil, such acid magma, seak, or grease merely requiring a longer boiling and a stronger alkali to effect the saponifi¬ cation than is required by the ordinary process, and I further propose to use the “magma,” “seak,” or grease extracted from the sewage or 35 suds by the processes described in the said Specification of the Letters Patent, No. 2534, A.D. 1870, or as above after acidulation as substances for the production of grease, tallow, oil, and stearine by any of the ordinary and well known processes, and such other matters or substances procured by the same processes as cannot be utilized for the purpose
