This paper is a continuation of one already submitted to the Society, and published in their Proceedings.

It showed that an equation of the form yn(x + a) = b could be applied to give close representation of results in the determination of the law of decrease of torsional oscillations of wires of different materials. This empirical equation, in which y represented the range of oscillation, x the number of oscillations since the commencement of observations, and n, a, and b constants for any one experiment, their numerical values depending upon the initial conditions of the wire and its subsequent treatment, was found to hold over a large range of oscillation for wires of many metals, and the present paper gives an account of further work on the subject.
