SILVER (Plate VI, 4) follows copper in the constitution of five of the
bodies enclosed in the funnels. But the triangular group contains
twenty-one atoms as against ten, and three ovoids, each containing three
bodies with eleven atoms, raise the number of atoms in a funnel to
seventy-nine. The central globe is decreased by five, and the prisms have
disappeared. The connecting rod is unaltered.

Atomic weight 107.93
Number weight 1945/18 108.055
(This atomic weight is given by Stas, in _Nature_, August 29, 1907, but it
has been argued later that the weight should not be above 107.883.)
[Illustration: PLATE VII.]
GOLD (Plate VII) is so complicated that it demands a whole plate to itself.
