Professor Osbourn Reynolds has donemuch to elucidate this question, and in one of hisearly papers on the subject he enunciated the lawthat •• the heat carried off by any fluid from a surface,apart from the effect of radiation, is proportional to. 1 aries in the engine room of modern steamers referredto. The evaporatoi and feed-heater herewith illus-trated are made by Messrs. Andrews & Cameron,Kelvin Engineering Work^, Kirkintilloch, , andare now being extensively fitted on board pasteamers and steam yachts. Evaporators which havebeen at work since the beginning of 1903 have mamtained theii specified production with remarkableregularity and have required the minimum of attentionand cleaning. Rankine pointed out man) years ago, whenring to surface condensers, that the rapidity of con tli. internal diffusion of the fluid at and neat tinsurfa is proportional to the rate at which particles or molecules pass backwards and forwardsfrom the surface to any given depth within the very simple experiment will show the remarkable effect i>l diffusion ol liquii e transmission ol through thin metal plates. fake a glass of coldwatei. having a small tin vessel tilled with hot waterimmersed up to the same v el
