| Description | Churchman presents a description of his new engine for raising water 'in which horses or other animals draw, without any loss of power (which has never yet been practised) and how the strokes of the pistons may be made of any length, to prevent the loss of water, by the too frequent opening of values with many other advantages, altogether new the model of which was shewn to the Royal Society on the 28th of last November'.
