Excerpt from Tables for the Determination of Minerals: By Means of Their Physical Properties, Occurrences, and Associates The successful determination of minerals at sight depends upon the ability to make quick and accurate distinctions between the physical properties, occurrences, and associates of the several minerals which may be suggested by the luster, color, form, streak, and hardness, especially, of a given specimen. As a result Of extensive experience in the laboratory and field, luster and color have been made the fundamental basis of these tables, further subdivisions being introduced by the streak and hardness. Minerals with similar physical properties are thus grouped together, aiding the student materially to acquire the necessary facility to make rapid distinctions. The tables include 250 of the most common minerals, classified into three groups, which may be designated as (1) very common, (2) common, and (3) not common, but important. The display given to the name of a mineral indicates at a glance in which of the above groups it has been placed. Page references to several textbooks on mineralogy will be found of great convenience when more detailed descriptions are desired than obviously can be given in determinative tables.
