IAN. See WATSON, JOHN.
MACLE (mak'el), in mineralogy, a variety of andalusite, occurring in long, tapering crystals in clay-slate. They have the axes and angles of a different color from the rest of the crystals, owing to a regular arrangement of impurities in the interior. In transverse section they exhibit a cross or a tassellation, the outlines of which are frequently rhombs.
