LXXII. An engine for raising water by fire; being on improvement of saver'y construction, to render it capable of working itself, invented by Mr. De Moura of Portugal, F. R. S. described by Mr. J. Smeaton.

This engine consists of a receiver, a steam and an injection-cock; a suction and a forcing-pipe, each furnished with a valve; together with a boiler, which, on account of its bulk and weight, is not sent with the rest; but, as it may be of the common globular shape, and having nothing particular in its construction, a description of it will not be necessary, as also the rest of these parts already mentioned being essential to every machine of this kind, a further account of them may be dispensed with.
