Book excerpt: Excerpt from A Key for the Determination of Rock-Forming Minerals in Thin Sections Tables for the determination of minerals have heretofore been made of secondary importance in text books. In this volume the reverse method has been adopted and the de scriptive tables make up the greater portion of the book. Theoretical discussions in optics have been avoided so far as possible, and only enough has been given to make clear that which is necessary for the practical determination of the minerals. The material has been condensed as much as is consistent with clearness, and all of the descriptions are given in as concise a form as possible. Owing to the difficulty of having the pages of the index indented by machinery, it was found necessary to extend the leaves to the full width of the book, and to indicate the lines along which the student should cut the pages. After trim ming along the lines shown, it will be found convenient to form another index guide by cutting off about one-half inch from the upper right hand corners of the pages descriptive of negative minerals.

Book excerpt: Unlike some other reproductions of classic texts (1) We have not used OCR(Optical Character Recognition), as this leads to bad quality books with introduced typos. (2) In books where there are images such as portraits, maps, sketches etc We have endeavoured to keep the quality of these images, so they represent accurately the original artefact. Although occasionally there may be certain imperfections with these old texts, we feel they deserve to be made available for future generations to enjoy.

Available in PDF, EPUB and Kindle. Book excerpt: Excerpt from Tables for the Determination of the Rock-Forming Minerals: With a Chapter on the Petrological Microscope There is probably no branch of geology in which an unaided student has more difficulty in making a start than in the microscopic study of rocks. This is especially to be regretted, as it is now recognised that this method of research is indispensable for any accurate work on the igneous rocks. Many a resident on the great volcanic plateaux of India, Africa, or America, or on the vast tracts of gneiss and schists which form such a large proportion of the earth's crust, is debarred from geological work by the difficulty of identifying minerals under the microscope. Thus our knowledge of many of these areas is very deficient, for they are only known by occasional rapid traverses; and the problems they present are so complex that they can only be fully worked out by a resident or by a thorough survey. Elementary students feel the difficulty, though they have the advantage of personal instruction. Probably every one who has tried elementary teaching in geology has felt the need of some simple book of reference. The elaborate tables of Rosenbusch and Michel Levy and Lacroix are, of course, perfect in their way, but they are really summaries of the characters of the minerals rather than guides to their rapid determination. With these, if one knows the name of a mineral, its characters can be at once ascertained; but what the student usually requires is the reverse process. He can recognise the characters of a mineral by the microscope, and from these he wants to know its name. The previous tables afford little assistance in doing this. Professor L winson-Lessing has now supplied this want by a set of tables arranged on what may be called the "dichotomous method."

Available in PDF, EPUB and Kindle. Book excerpt: Excerpt from Rock-Forming Minerals Students on the Continent are well supplied with text-books giving instruction in the more recent methods of petro graphical research; but in this country it is otherwise, and those who wish for such teaching in their own tongue fare badly, unless they can attend lectures and devote their time to a course of systematic work in the laboratory. Even then there is a constant demand for a book to which they can refer for information enabling them to determine the chief rock forming minerals. Yet, although many of the works now published supply them with much that is useful, this want seems still to remain unsatisfied. It is essentially a student's want. Whether this book will in any way meet it, at least for the time being, is a question best answered by the book itself.
