    White's Improvements in Treating Sewage. SPECIFICATION in pursuance of the conditions of the Letters Patent, filed by the said William White in the Great Seal Patent Office on the 23rd January 1874. TO ALL TO WHOM THESE PRESENTS SHALL COME, I, William g White, of 30, Thurlow Hoad, Hampstead, in the County of Middlesex, send greeting. WHEREAS Her most Excellent Majesty Queen Victoria, by Her Letters Patent, bearing date the Twenty-fourth day of July, in the year of our Lord One thousand eight hundred and seventy-three, in the thirty-seventh 10 year of Her reign, did, for Herself, Her heirs and successors, give and grant unto me, the said William White, Her special license that I, the the said William White, my executors, administrators, and assigns, or such others as I, the said William White, my executors, administrators, and assigns, should at any time agree with and no others, from time 15 to time and at all times thereafter during the term therein expressed, should and lawfully might make, use, exercise, and vend, within the United Kingdom of Great Britain and Ireland, the Channel Islands, and Isle of Man, an Invention for “ Improvements in the Treatment of Sewage and Cesspool Water,” upon the condition (amongst others) that 20 I, the said William White, my executors or administrators, by an instrument in writing under my, or their, or one of their hands and seals, should particularly describe and ascertain the nature of the said Invention, and in what manner the same was to be performed, and cause the same to be filed in the Great Seal Patent Office within six calendar 25 months next and immediately after the date of the said Letters Patent. NOW KNOW YE, that I, the said William White, 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, that is to say :— 30 Chloride of calcium is a waste product in several large manufactures, and is generally thrown away as of no value, but it is exceedingly soluble, and in presence of sulphates precipitates sulphate of lime ; and in presence of alkaline carbonates and phosphates precipitates carbonate aud phosphate of lime, I have found it well adapted for the treatment of 35 ordinary sewage and cesspool water.
