The principles of hydrostatics; an elementary treatise on the laws of fluids, and their practical applications
Thomas Webster's elementary treatise on the laws of fluids and their practical applications, published in London by J.W. Parker in 1856 for students and self-taught readers of physics. The nine plates are line diagrams of pumps, siphons, gasometers, bell jars and lever-balanced cylinders, drawn in heavy uniform outline with letter keys, usable as clean schematic silhouettes or as sources of valve, pipe and vessel shapes.
