  • Order 1. Homogeneous.

Calamine, or Oxide of Zinc, is here truly imitative. In the present instance it much resembles Flos-Ferri*, which, however, is generally more varied in its form. This is a rare specimen, which was presented to Sir Joseph Banks by my kind friend G. Laing, Esq., and comes from Wanlockhead mine, in Scotland.

  • * Flos-Ferri is well known from the Styria Iron mines, and is mostly of a fine white, and coralliform shape, like tab. 9, but with a surface finely covered with minute speculated crystals, giving it a soft downy appearance. We have moderate specimens from Scotland. The lower figure is from a botryoidal specimen from the same place.
