Abstract
The object of the present paper is mainly to point out a simple method of obtaining the efficiency of the class of steam pumps upon Savary's old plan, variously denominated, “steam vacuum pumps,” “pulsometers,” “aquometers,” etc., and at the same time to show, notwithstanding the imperfection of the data, given of the experiments upon one of this class, their great inferiority in economy of power to ordinary piston or plunge pumps, especially for grent lifts.
