necessary. Fig. 6 is a Greek vase, with handles, of many attempts to discover if there was any fundamental principle to which this peculiar beauty was to be ascribed. All parties seem to have agreed that it depends on various modifications of a curved line. Mr. Reinagle, the Royal Academician, endeavoured to show, in a lecture delivered at the Royal Institution in 1827, that ovals of various sizes would mechanically produce various elegant and symmetrical outlines. His endeavour was to prove, “that a line formed by an elliptic curve was beautiful even in an abstract point of view, free from all association." To illustrate his views he employed various diagrams, such as are seen in the following figures.
