_Subdivision 1._

_Malleable Metals._

GOLD,
PLATINA,
PALLADIUM,
SILVER*
MERCURY**
TIN,
COPPER,
IRON,
LEAD,
NICKEL,
ZINC.

[Footnote *: These first four metals have commonly been
distinguished by the appellation of perfect or noble metals, on
account of their possessing the characteristic properties of
ductility, malleability, inalterability, and great specific
gravity, in an eminent degree.]

[Footnote **: Mercury, in its liquid state, cannot, of course,
be called a malleable metal. But when frozen, it possesses a
considerable degree of malleability.]

_Subdiv. 2._

_Brittle Metals._

ARSENIC,
BISMUTH,
ANTIMONY,
MANGANESE,
TELLURIUM,
COBALT,
TUNGSTEN,
MOLYBDENUM,
TITANIUM,
CHROME,
URANIUM,
COLUMBIUM _or_ TANTALIUM,
IRIDIUM,
OSMIUM,
RHODIUM.*

[Footnote *: These last four or five metallic bodies are placed
under this class for the sake of arrangement, though some of their
properties have not been yet fully investigated.]

Oh, what a formidable list! You will have much to do to explain it,
Mrs. B.; for I assure you it is perfectly unintelligible to me, and I
think rather perplexes than assists me.

MRS. B.

Do not let that alarm you, my dear; I hope that hereafter this
classification will appear quite clear, and, so far from perplexing you
