Side 6 - To every action there is always an equal and contrary reaction ; or the mutual actions of any two bodies are always equal and oppositely directed.
Side 235 - ... by a moving mass ; that it is not discontinuous or granular ; and hence, that, as a whole, it may be compared to an impalpable and all-pervading jelly, through which light and heat waves are constantly throbbing, which is constantly being set in local strains and released from them, and being whirled in local vortices, thus producing the various phenomena of electricity and magnetism ; and through which the particles of ordinary matter move freely, encountering but little retardation if any ;...
Side 783 - FREDERICK BEDELL, HOMER J. HOTCHKISS, CHARLES P. MATTHEWS, and THE EDITOR. Cloth, pp. 444. $3.25The first volume, intended for beginners, affords explicit directions adapted to a modern laboratory, together with demonstrations and elementary statements of principles. It is assumed that the student possesses some knowledge of analytical geometry and of the calculus. In the second volume more is left to the individual eflort and to the maturer intelligence of the practicant.
