Abstract
THIS new production of Prof. A. N. Winchell is, we believe, unique, at any rate so far as the English language is concerned. It is a compilation of data collected by the author during the preparation of the second edition of the descriptive part of his “Optical Mineralogy.” The title is misleading, since by far the greater number of the chemical compounds the optical properties of which are described are not found in Nature, and hence are not ‘minerals’ in the commonly accepted sense of the term.
