Excerpt from Guide to the Mineral Collections in the Illinois State MuseumIn the following pages an attempt has been made to so describe the minerals constituting our constantly growing collections as to emphasize the most important ones and at the same time to present to the reader a good idea of the science of mineralogy. The average visitor approaches the subject as a child would and just as the human race has done. When early man wandered up stream courses and found a gold nugget he doubtless was attracted by its yellow color, in time noticed the weight, softness, etc., and learned to use it as an ornament. The child does the same, using the senses of sight, feel, taste, and smell in making the acquaintance of any strange sub stance. Hence the physical characteristics - form, color, hardness, and weight - oi various minerals are described, and then their chemi cal constituents, geological and geographical relations, and use are given. By becoming acquainted with various minerals the visitor obtains a knowledge of the science.About the PublisherForgotten Books publishes hundreds of thousands of rare and classic books.
