Having now shown the method of putting the plan of any object, when bounded by right lines, into this perspective, before pro-ceeding to the consideration of objects with regard to height, we would recommend the reader who may read this, and who would wish to become acquainted with this useful branch of science, to make all the figures two or three times the size A here shown, and afterwards progressively intro- - duce others which the fancy may dictate—such as quadrilaterals, pentagons, hexagons, &c.—as a short practice will sooner and more efficiently bring it home to the mind than any descriptions, no matter how well and how easily written.
