    Vertices Improvement in Deodorizing Sewage Waters, <Sfc. when Lime is used. And in order that my said Invention may be most fully understood and readily carried into effect, I will proceed to describe more fully the manner in which I prefer to conduct the process over the sewer through which the sewage to be deodorized passes, and at a short distance from the mouth of the said 5 sewer a circular vessel of wood or other material is erected, and in the centre of this vessel is placed an upright shaft, having on it stirring arms, which when the shaft revolves sweep the whole surface of the vessel at a short distance from its bottom. To the vessel thus arranged a pipe leads in a con¬ tinuous stream of water, and there is another pipe which leads the water after 10 it is mixed with the lime into the sewer through which the sewage is passing. By the side of the mixing vessel there are lime kilns, in which the lime required for the process is burnt, and from one of these kilns a workman con¬ tinually takes quantities of the lime, while it is still hot from the burning, and throws it into the mixing vessel, where it becomes mixed with the water also 15 introduced into the mixing vessel. Or, if sea water can be obtained, I find it advantageous to use it in place of fresh water for mixing with the lime. The quantity of lime which is necessary to deodorise a measure of sewage will vary; but I find it generally advisable to employ the lime in the pro¬ portion of twenty-six tons of lime per annum for every one thousand persons 20 of the population of the locality drained by the sewer. Having thus described the nature of my Invention, and the manner of performing the same, I would remark that I am aware that lime has heretofore been mixed with sewage for the purpose of deodorising the same, I do not therefore claim the same generally ; but what I do claim is, the mixing the lime 25 while it is still hot from the burning with water and then adding the mixture to the sewrage to be deodorised. In witness whereof, I, the said George Julius Vertue, have hereunto set my hand and seal, this Twenty-eighth day of May, in the year of our Lord One thousand eight hundred and fifty-seven. SO GEO. J.
