Abstract
WHEN an author puts forward perfectly new views in opposition to those generally accepted, using technical terms like force and energy in several new senses, it is very difficult to find out exactly what he means. In his definitions he says that gravitation resists all impressed motion with a force as the square of the velocity. He defines vis inertiae as the force with which matter resists motion. It is as the mass multiplied by the square of the motion resisted. After defining momentum, he says that it is resisted by the inertia of matter in its origin and in its progress, whereas Newton's first law of motion supposes inertia to resist its origin but to sustain its progress. The author's membership of many learned societies might warrant the belief that he has some meaning in what he says, but it is certainly very carefully concealed.
