Excerpt from Dictionary of Chemistry: With Its Applications to Mineralogy, Physiology, and the ArtsA familiar acquaintance with the study of ores and minerals for many years, together with the advantages of an extensive private museum, rendered historical by its having been founded by the late Dr. Thomas Thomson, have enabled the author to supply a copi ous index of mineralogical synonymes, in pddition to many new analyses, first time. The preservation Of the study of minerals, that is of element in nature, as the essential basis of the science of Chemistry, seems so attempts to restrict mineralogical arrangements to mere crystallographic systems, are much to be regretted, since that valuable auxiliary in the discrimination of physical forms is as thoroughly applicable to artificial salts as to those found in nature. Following out this view, many species have been restored, in this volume, which crystallographers have removed from the mineral list, either from their similarity in per centage composition to previously described compounds, or from their amorphous condition, without, perhaps, viewing the subject in the true chemical aspect, which usually presents us with a prospect of the most important bodies in nature, not in a definite shape, but as clods and glebe without crystalline characters, and therefore in a condition admirably suited to produce that endless variety of form in nature which even custom cannot stale, and only renders still more worthy of our and regard.About the PublisherForgotten Books publishes hundreds of thousands of rare and classic books.
