The individual are again divided into the absolute and the relative; the absolute being those which relate to figure, division, surface, texture, size, duration, colour, variegation, and veining; and the relative, those which relate to ï¾µstivation, direction, and insertion. The collective terms relate to arrangement and number. This mode of grouping the terms together is intended to facilitate the labour of acquiring them.
