Excerpt from Technical Methods of Ore Analysis
It has been found necessary to again revise this book. A number of new methods have developed, notably those for Molybdenum, Potassium, Tungsten and Uranium, which have been replaced in the Appendix. New matter has been inserted in the text at various points, and error as far as found, corrected. Some of the older methods, no longer preferred for regular use, have been allowed to remain, as possibly useful in special cases or situations.
