Ver. 100. Far-extended heel—The personification of Rectangle, besides answering a poetical purpose, was necessary to illustrate Mr. Higgins’s philosophical opinions. The ancient mathematicians conceived that a cone was generated by the revolution of a triangle; but this, as our author justly observes, would be impossible, without supposing in the triangle that expansive nisus, discovered by Blumenbach, and improved by Darwin, which is peculiar to animated matter, and which alone explains the whole mystery of organization. Our enchanter sits on the ground, with his heels stretched out, his head erect, his wand (or hypothenuse) resting on the extremities of his feet and the tip of his nose (as is finely expressed in the engraving in the original work), and revolves upon his bottom with great velocity. His skin, by magical means, has acquired an indefinite power of expansion, as well as that of assimilating to itself all the azote of the air, which he decomposes by expiration from his lungs—an immense quantity, and which, in our present unimproved and uneconomical mode of breathing, is quite thrown away. By this simple process the transformation is very naturally accounted for.
