    Fenton’s Improvements in the Furification and Utilization of Seivage, fyc. being also applicable for the extraction of grease, “ magma,” or “seak” from the spent liquors or sewage of woollen mills, bleach or silk works or other factories, wash houses, wool or sheep washing mills or pools. The Invention also relates to the making of soap direct from such grease, “ magma,” or “ seak ” and is partly an improvement upon the 5 subject matter of Letters Patent granted to me and Samuel Hollins, of Bolton, in the County of Lancaster, and dated 21st September 1870, No. 2534 In addition to the processes or modes of treating sewage or factory or other waste waters described in the Specification of the Letters Patent 10 above referred to, I propose to use aeration to quicken and perfect the precipitation of the polluting matters whether in suspension or solution by passing through, into, under, or upon the sewage (either 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 pro- 15 duced by any convenient mechanical means, and I also propose to apply the same for the extraction of “magma,” “seak,” or 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,” “ seak,” or grease from any 20 waters containing them by the processes described in the Specification before named or 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 25 known process of soap making direct, without the necessity of first extracting 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, and also to use “ magma,” “ seah/ or grease which has been obtained from such waters or refuse 30 by the common process of extraction by the use of acids or acid salts 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 35 to use the “magma,” “seak,” or grease extracted from sewage or suds by the piocesses described in the said Specification of the Letters Patent No. 2534/70, or as above, after acidulation, as substances for the pro-
