Abstract
IT has always seemed a matter for regret that so many of the names applied to mineral species, even in recent years, give no indication whatever of the chemical composition or physical properties of the mineral. Instead of attempting to clarify the science by devising a self-explanatory system of nomenclature, mineralogists continue to increase the tax on their memories by attaching to new minerals quite irrational names. This being the case, Dr. Simpson justifiably claims that his tables may be regarded as a vade mecum to everyone interested in minerals. He has listed in alphabetical order upwards of 1800 mineral names. Opposite each mineral is stated concisely its chemical composition, specific gravity, crystal system and refractive indices. These data have been collected from the latest and most accurate sources available. In addition, reference is given in every case to a source of detailed information regarding each mineral. The latter item is particularly valuable in the case of the newer mineral species, about which data have, until now, remained scattered through many publications.
