Whilst the greatest effort has been made to ensure the quality of this text, due to the historical nature of this content, in some rare cases there may be minor issues with legibility. It was not without reason that d'alembert affirmed, Philosophers are bewildered by the spectacle of a falling stone. The bewilderment of the illustrious Newton is manifest on referring to the earliest edition of his Principia, in which he says, The ultimate particles of matter are endued with inherent forces, or powers of attrac tion and repulsion. Subsequently, in treating of the universal attraction of gravitation, he says Gravity must be caused by an agent acting con stantly, and according to certain laws; but whether this agent be material or immaterial, I leave to the imagination of my readers.
