The desire of an increasing number of students for more complete information in regard to modern petrographic-microscopic methods than is to be found in any English work on the subject,has led excellent elementary and intermediate text-books on optical minerralogy,and certain portions of most crystallographies and mineralogies,are devoted to microcopic methods.
