Part 57 (2/2)

(3) on charcoal. As the preceding, except that a large quant.i.ty of AsO^{3} and but little SbO^{3} are given off.

(4) in forceps. --

(5) in borax. --

(6) in mic. salt. --

(7) with carb. soda. As stephanite, except that much a.r.s.enic is given off and but little antimony.

(8) Special reactions. --

Mineral. Horn silver

Formula. AgCl.

Behavior

(1) in gla.s.s-bulb. Fuses, but undergoes no further change.

(2) in open tube. --

(3) on charcoal. Fuses readily in the oxidizing flame. In the reducing flame is slowly reduced yielding metallic silver.

(4) in forceps. --

(5) in borax. --

(6) in mic. salt. --

(7) with carb. soda. Is rapidly reduced to metallic silver.

(8) Special reactions. If cut up into small pieces mixed with oxide of copper and then heated before the oxidizing flame upon charcoal, it colors the flame blue.

THE END.
