Garnet has been divided into six sub-species, viz.:— I. Alumina-lime Garnet, consisting of sili-cates of alumina and lime. II. Alumina-magnesia Garnet, consistingof silicates of alumina and magnesia. III. Alumina-iron Garnet, consisting ofsilicates of alumina and iron. IV. Alumina-manganese Garnet, consist-ing of silicates of alumina and manganese. GARNET. V. Iron-lime Garnet, consisting of sili-cates of iron and lime. VI. Lime-chrome Garnet, containing limeand oxide of Chromium. I. Lime-garnet or Grossular, consists of Ca5 Si+Al Si-(Ca3 + Al) Si=silica 40-1,alumina 22-7, lime 37-2 = l00-0. Colour pale greenish, clear red, and red-dish orange ; also cinnamon colour. H. 65to 7. 3-43 to 3-73. BB fuses to a slightly greenish glass orenamel. Soluble, when powdered, in concentratedmuriatic acid. This section comprises Ci
