Absolute Measurements in Electricity & Magnetism.

Small 8vo. xix, [1], 384, 12, 88 pp. 66 figs., index. Original burgundy blind- and gilt-stamped cloth; spine faded. Ex-library markings (spine call no. removed). Very good. Second edition (first issued in 1883). "This little book was originally intended to be mainly a reprint of some papers on the Measurement of Electric Currents and Potentials in Absolute Measure contributed to NATURE during the winter of 1882-3; but as these were being reprinted, many alterations and additions suggested themselves, which it was thought would render the book more generally useful. Most of the additional matter is mentioned in the introductory chapter, but I may here refer to a sketch of the theory of alternating machines, and of methods of measurement available in such cases, contained in Chapter X., and to Chapter XII. on the Dimensions of Units, which I have thought it desirable to introduce. The work has of course no pretensions to being a complete treatise on Electrical and Magnetic Measurements, but is rather designed to give as far as is possible within moderate limits a clear account of the system of absolute units of measurement now adopted, and of some methods and instruments by which the system can be applied in both theoretical and practical work. I am under great obligations to Sir William Thomson and to Mr. J. T. Bottomley, who have kindly examined some of the proofs, and favoured me with valuable suggestions." (preface, author). / Andrew Gray FRS FRSE, Scottish physicist and mathematician, was associated with the University of Glasgow. He became the assistant and private secretary of Professor William Thomson (later Lord Kelvin). He remained in Bangor until 1899, when he returned to Glasgow to become the Professor of Natural Philosophy, succeeding Kelvin on his retirement.
