Ca.

(4) in forceps. V. Frequently colors the flame slightly red.

(5) in borax. Gives the manganese and iron reactions.

(6) in mic. salt. As in borax.

(7) with carb. soda. Forms an infusible slag.

(8) Special reactions. In warm acid dissolves with much effervescence.

Mineral. Triplite

Formula. ([..Mn][.Fe])^{4}[.....P].

Behavior

(1) in glass-bulb. Generally gives off more or less
water.

(2) in open tube. --

(3) on charcoal. --

(4) in forceps. I. Colors the outer blowpipe flame green
([.....P]).

(5) in borax. Gives the manganese and iron reactions.

(6) in mic. salt. As in borax.

(7) with carb. soda. Forms an infusible mass.

NICKEL AND COBALT.

* * * * *

Mineral. Millerite

Formula. NiS.

Behavior

(1) in glass-bulb. --

(2) in open tube. Evolves SO^{2}.

(3) on charcoal. Fuses with much ebullition to a magnetic bead.

(4) in forceps. --

(5) in borax. The roasted mineral gives a nickel reaction,
slightly modified by small quantities of iron
and copper.

(6) in mic. salt. As in borax.

(7) with carb. soda. Fuses to a slaggy mass, which on silver gives
the sulphur reaction.

(8) Special reactions. --

Mineral. Coppernickel

Formula. Ni^{2}As.

Behavior

(1) in glass-bulb. Gives off a little AsO^{3}.

(2) in open tube. Gives off much AsO^{3} and some SO^{2} and falls
to powder.

(3) on charcoal. Fuses to a magnetic bead, with the evolution of
arsenic, which colors the flame blue.

(4) in forceps. --

(5) in borax. The arsenical bead obtained by fusing the
mineral on charcoal, if fused upon the same
support with borax successively added and
removed, gives firstly an iron reaction, then
