...auxiliary. Thus, each of the magnitudes of extension may be regarded as produced by the motion of its limit; **a line, by the motion of a point; a surface, by the motion of a line;** and a solid, by the motion of a surface. II. A. a.) Draw, between the points A and B, a line of which... | |

...Fluxions, quantities are regarded as being generated by motion ; a line being supposed to be produced **by the motion of a point, a surface by the motion of a line,** and a body by the motion of a surface. The comparative velocities or rates of such motions are called... | |

...By the conception with which the draughtsman is mainly concerned, a line is considered as generated **by the motion of a point; a surface by the motion of a line.** He regards a straight line as generated by a point moving always in the same direction;* a curve as... | |

...surface is a line, and of a line, a point. He next proceeds to shew that, in general, a line is generated **by the motion of a point, a surface by the motion of a line,** and a solid by the motion of a surface. Explaining the notions of congruency, reciprocity, axial and... | |

...triangle in 2-space, and the regular tetrahedron (regular pyramid), in 3space. 4. As a line is generated **by the motion of a point, a surface by the motion of a line,** a solid by the motion of a surface, so a fourth-dimensional body may be generated by some motion of... | |
