Abstract
IT is not stated whether this book is intended for use as a textbook, although on perusal this seems to be the case. It would perhaps have been preferable to mention the degree of mathematical knowledge desirable in the reader; some of the workings given in the earlier portions are detailed, while later portions omit stages in the calculations, and in this way difficulty might be caused to students who seldom use plane and spherical trigonometry. The working on page 9, from which formulae for finding the true dip of a bed from three points of outcrop are derived, would be easier to follow had a figure been appended.
Dip and Strike Problems Mathematically Surveyed.
