Abstract
FORMERLY known as “The Optic and Microscopic Characters of Artificial Minerals”, the modification in the title of the new edition of this work serves to prevent misapprehension as to its scope. This is, in fact, much wider than would be the case if it dealt only with synthetic minerals, using the latter term in its generally accepted sense. The author has attempted to include all inorganic substances the optical constants of which are known.
The Microscopic Characters of Artificial Inorganic Solid Substances or Artificial Minerals.
By Prof. A. N. Winchell. With a Chapter on the Universal Stage, by Prof. R. C. Emmons. Second edition. Pp. xvii + 403. (New York: John Wiley and Sons, Inc.; London: Chapman and Hall, Ltd., 1931.) 31s. net.
