CHAPTER XVII.
IOLITE.
NDER the name of lolite or Dichroite the mineralogist is familiar with a certain stone which is remarkable for its pleochroism, ro differences of tint when viewed in different directions. Occasionally it is cut and polished as a gem-stone, and is known to the jeweller as Saphir d'eau. The best specimens come from Ceylon, those from Bavaria being almost opaque. It is also found at Haddam, Con­necticut. The usual colours are various shades of blue and violet, whence the name " lolite." The dark blue lolite is sometimes known as Lynx-sapphire, but this term is also occasionally applied to an indigo-blue variety of true sapphire.
