[After the Norwegian God of War, Tyr; suff. -ite (Min.).] Min.: A mineral occurring in pyramidal crystals, embedded in orthoclase, but implanted on black mica, at localities near Hampemyr, Arendal, Nor Hardne , 65; specific gravity 5-13-5-56. Composition: E entially a columbate of yttrium, cerium, and iron. Is referred by most mineralogists to Fergusonite (q. v.). way.

Hardne , 10-20; specific gravity 3-02-3-098; luster on cleavage faces pearly; color, pale apple and verdigris-green, sometimes inclining to blue; trans lucent to sub-translucent; sectile. Composition: Arsenic acid, 29-2; protoxide of copper, 50'3; water, 20.5=100, with the resulting formula, CuO.H3AsO4+ 9H2O; the analysis, however, showed 13.65 per cent. of carbonate of lime, which Church has lately shown is probably present as an e ential constitu ent, and not as an impurity. If this view be sustained, the formula will need modification. *tŷr -ōne, subst . [Lat. tironem , acc us, of tiro a tyro (q. v.).] A tyro.
