Publisher's Synopsis
Excerpt from Descriptive Mineralogy
Tm: following pages are presented with the purpose of afiording students a comprehensive view of modern mineralogy rather than a detailed knowledge of many minerals. The minerals selected for description are not necessarily those that are most common nor those that occur in greatest quantity. The list includes those that are of scientific interest or of economic importance, and, in addition, those that illustrate some principle employed in the classification of minerals. The volume is not a reference book. It is offered solely as a textbook. It does not pretend to furnish a complete discussion of the mineral kingdom, nor a means of determining the nature of any mineral that may be met with. The chapters devoted to the processes of deter minative mineralogy are brief, and the familiar key to the determina tion of species is omitted. In place of the latter is a simple guide to the descriptions of minerals to be found in the body of the text. For more complete determinative tables the reader is referred to one of the many good books that are devoted entirely to this phase of the subject. In the descriptions of the characteristic crystals of minerals both the Naumann and the Miller systems of notation are employed, the former because of its almost general use in the more important refer ence books and the latter because of its almost universal use in modern crystallographic investigations. The student must be familiar with both notations. It is thought that this familiarity can be best acquired by employing the two notations side by side.
