A condensed account of it appears in " Paxton's Magazine," vol. ii. p. 249, from which we make the following extract:—" The writer suggested the mode of heating the water to a friend in France, who had built a small green- house in front of his dining-room, where there was no convenient place to erect the brickworkfor a common boiler, nor any chimney into which a flue could be turned. It occurred to him that, by having a small cylinder boiler constructed like those ori- ginally employed in the high-pressure steam-engine, containing the furnace in a smaller cylinder within the first, and sur- rounded by the water, no brickwork would be required; and that by burning a mixture of charcoal and cinders, the inconvenience of smoke would be avoided, and sufficient draught obtained by a moderate length of stove pipe passing through the roof.
