    Excerpt from Absolute Measurements in Electricity and Magnetism

    To the late Mr. E. B. Rosa and his colleagues of the physical staff of the Bureau of Standards at Washington I am under many Obligations. They tested and used my suggestions as to standards and formulae of inductance, and constructed an accurate electrodynamometer of the special dimensions recommended in my Phil. Mag. Paper of 1892, and in the First Edition of this book. They have carried in their writings the investigation of the accuracy of formulae, and the allowance for errors of different kinds, to a high pitch of perfection. Their numerical comparison of formulae and their exact computation of the constants of apparatus have not been such as to attract popular attention and applause, but it has been none the less of enormous value to scientific progress. This merit it has in common with the whole work of the British Association Committee on Electrical Standards and of all those scientific men who have laboured at the subject of absolute electrical measurement. This task of founding a system of absolute measure ments was forced upon science by applications to submarine telegraphy, and it is not too much to say that without such a system not one of the immense and varied range of practical applications could ever have been made.

    I am indebted to my friend and former pupil, Professor E. Taylor Jones, who has made an elaborate theoretical and experimental study of the induction coil, and is an acknowledged authority on that subject, for the account of the action of such apparatus, which appears in Appendix I.

    The Table of Contents and the Index have been constructed by my eldest daughter, to whose unfailing patience and ready help as amanuensis I have had continually to turn.

    I wish finally to acknowledge the care of the readers and compositors of the University Press, which, by comparison of references, and other wise, has saved the text from many inconsistencies, and increased its accuracy.
