    JBradburns Improvements in Treating Excrementitious Matters, cfyc. The condensed matters in the condensers are distributed on the farm by means of hose, or mixed with water from a stream, and employed to irrigate the land ; or they may be applied to the land in any other convenient manner, Tbe oven may be charged with the waste or refuse matters produced on the farm, and the ash or dried contents of the said oven withdrawn every 5 • day or every other day, the said ash being, applied to the land or otherwise used. In applying my Invention to the manufacture of artificial manures I attach an oven to the ordinary boilers of the manufactory, the said oven having pipes passing through it heated in the manner herein-before described. 10 I charge the said oven with all the refuse animal and vegetable matters obtainable. The gases or volatile matter driven off by the heat is conducted by pipes to a series of condensers of the kind hereinbefore explained. In these condensers nearly the whole of the volatilized matters are condensed, the uncondensed gases or vapours being conducted into the sulphur burners 15 of the sulphuric acid works. In this way al] the valuable portions of the uncondensed gases or vapours from the refuse matters will be taken up, and all nuisance prevented, The liquid obtained is used in the manufacture of superphosphate of lime in lieu of water. The ash or dried contents of the oven may be used as herein-before described. Any uncondensed gases pro- 20 duced in the treatment of night soil and farm refuse may, where convenient, be burned in the sulphur burners of sulphuric acid works. When the ovens used for treating night soil are large I prefer to employ agitators for stirring the contents, which agitators may be worked by hand or driven by steam or other motive power, $5 Having explained the nature of my Invention, I will proceed t o describe, with reference to the accompanying Drawings, the manner in which the same is to be performed Figure 1 represents in vertical section, and Figure 2 in elevation the apparatus which I employ for the treatment of night soil in towns and other SO places. The same letters of reference indicate the same part in both Figures. a is a closed air-tight oven situated near the fire-place b9 and heated by the waste heat of the said fire-place ; the said fire-place b may be one of the ordinary fire-places of the house or other building ; the waste heat passes from the fire-place b along the flue c to the chimney d. e is a damper by which the 35 draught through the flue c may be regulated; / is the pan of the watercloset, and g the seat. The soil from the pan f passes into a receptacle h, from which it may be allowed to fall into the lower receptacle or reservoir iy and stored therein prior to its introduction into the oven a. h is a hopper containing
