The vessel 0 contains the twotubular vessels, 2 anil 13, the lower of which is immersedin impure water undergoing distillation. Steam issupplied from a boiler through pipe 12 and steamreducing valve 13 into ;, where it condenses, passingaway through steam trap 23, either by pipe IS or by pipe19 into vessel 20, where it mixes with the secondarycondensed water in the upper vessel. Cold water issupplied through pipe 1 to the upper condenser, andcondenses the steam arising from the condensing .vaterin the lower part of the apparatus ; this mixes in 20 withthat from 15 and is carried by pipe 21 to any desired and bedded on the drainage faces of the chambers of thefilter-press. The tiles or porous composition consist ofcharcoal, blue clay, ball clay, China clay, flint and stonemixed together with water, formed into cakes and fired. -C. C. H.
