Extract

The mineral to which I have given the name of Sodalite, was also put into my hands by Mr Allan. In the Greenland collection which he purchased, there were several specimens of a rock, obviously primitive. In the composition of these, the substance of which I am about to treat, formed a constituent, and, at first appearance, was taken for felspar, to which it bears a very striking resemblance.
