Whilst the greatest effort has been made to ensure the quality of this text, due to the historical nature of this content, in some rare cases there may be minor issues with legibility. In preparing the revised edition, Chapters I. And IV. Have been rewritten and enlarged and the part relating to the determination of the plagioclases has been greatly amplified. Many additions have also been made to Chapter III. And the Becke method, for the determination of the relative indices of refraction of minerals, has been given in detail.
