The Forces which carry on the Circulation of the Blood

Abstract

IN the same way that, among à priori mechanical philosophers, the possibility of discovering a perpetual motion was a favourite subject of discussion before the development of the theory of energy, so, among physiologists, the relative importance of the different forces which maintain the circulation of the blood was an equally common source of speculation before the introduction of the blood-pressure gauge and the sphygmograph. Within the last twelve or fifteen years, however, the various problems which used to occupy the attention of Magendie, Arnott, and Barry have been completely solved by entirely fresh methods of observation; and these, quite irrespective of their opinions, have verified or disproved their theoretical deductions according to whether or not they were based on sound premises.

The Forces which carry on the Circulation of the Blood.
