Abstract
THIS book is intended by the authors for students who have already completed an elementary course of practical physics. It is not, however, a treatise on methods of physical measurement, but the authors have described upwards of seventy typical experiments of an advanced and modern character. While the descriptions of these experiments are usually applicable to apparatus in general, they are in many cases somewhat sparse in detail. Thus, for example, in Expt. Ixiii., “Strength of a Magnetic Field by Bismuth Spiral,” no remarks are made on the necessity of maintaining the temperature of the spiral constant, which is of primary importance if trustworthy results are to be obtained by this method. These defects are, however, partially remedied by the references given by the authors at the commencement of each experiment to more advanced treatises and sources where the subject under investigation is dealt with more exhaustively. Such well-known text-books as Kohl-rausch, Watson, and Stewart and Gee figure conspicuously in this respect. The authors consider that the books and papers referred to in this way shoiild be consulted by the student before commencing the experiment. A few questions are usually appended to each experiment bearing upon its subject-matter, At the end of the book are tables of logarithms and physical constants.
