Asbestus—compact, in Pelham.
Garnets—very plenty in Conway, Deerfield, Shelburne, &c. Good specimens of the melanite occur in Conway.
Native Alum—in Leyden, in small quantities, efflorescing on argillaceous slate.
Sulphur—in Conway, Shelburne, and Warwick, efflorescing on mica slate.
Prehnite—in greenstone, Deerfield, encrusting the columns and in radiated masses, but rarely crystallized. The veins of it, when in place, are nearly perpendicular.
Zeolite—in same place, not abundant. Some good specimens of the radiated variety are found.
Chabasie—in same place, considerably abundant. No crystals have yet been found whose sides exceed a quarter of an inch. It occurs in the veins of the greenstone, in geodes, on balls of zeolite, on chalcedony, on lamellar quartz, &c.
Stilbite—in same place, not abundant. It is commonly associated with chabasie, and the crystals, though small, are well defined.
Analcime—in same place, very abundant, and is associated with quartz and amethyst, which are sometimes enclosed by analcime. It generally occurs in cylindrical, reniform, and radiated masses. A few perfect crystals only have been observed.
