Two solids are symmetrical when they are so situate dwith the respect to an intervening plane that the several points of their surfaces thus correspond to each other in position and distance. In analysis, an expression is symmetrical with respect to several letters when any two of them may change places without affecting the expression; as, the expression a^2b _ ab^2 _ a^2c _ ac^2 _ b^2c _ bc^2, is symmetrical with respect to the letters a, b, c.
