On Sericite from North Wales and on Penninite and Labradorite from Ireland

Published online by Cambridge University Press:  14 March 2018

Extract

For the first of the three minerals to be described in the following pages we are indebted to Mr. W. G. Fearnsides, who collected it in North Wales in the autumn of 1908, and we desire to express our best thanks to him for the readiness with which he placed at our disposal enough suitable material for a complete analysis. The other two minerals were collected by ourselves.
