Abstract

The Author, metals. Mr. Tritton's remarks regarding American injectors were fully borne out by the Author's experience. The American injector was perhaps rather more expensive than the English, but its advantages i n working were manifold. It would take water a t a temperature a good deal higher than the English forms, taking feed-water a t over 130" F, Once started it could be regulated over a very considerable range without blowing off, and if it did blow off it restarted with scarcely a pint of water wasted. It would work with steam-pressure as low as 25 lbs. per square inch. All engineers would agree with Mr. Robertson in his statements on elongation; but the fact that the object of the Paper was to ' describe what was being done, and not what should be done, must be the Author's excuse for not presenting the figures in any other form than that in which they appeared in the Paper.
