Excerpt from Practical Geometry, Linear Perspective, and Projection: Including Isometrical Perspective, Projections of the Sphere, and the Projection of Shadows, With Descriptions of the Principal Instruments Used in Geometrical Drawing, &C, Thus, for example, the mode of dividing a right line into any number of equal parts, as given in the theoretical problem, is far too circuitous and inaccurate in practice ever to be made use of, (geo. I. 7, Pr. 49 z) and as it is a problem of perpetual occurrence, and of great importance, not only in geometrical drawings, but in other arts, some method of solving it, at once correct in principle and easy in application, must obviously be given in a work on practical geometry.About the PublisherForgotten Books publishes hundreds of thousands of rare and classic books.
