On the Oscillations of a Viscous Spheroid

Abstract

This restriction may be removed if the summation 2 in (37) be supposed to indude negative as well aa positive values of n.The'suffixes attached to the symbols <f> H , Xn must then be taken to denote the algebraical degree, as distinguished from the prder, of these harmonics.* The introduction of this conrtant is suggested, of course, by Sir W. Thomson's result that the time of oscillation of a Motionless spheroid is 2*/j9, where fi has thft above value.
