الصفحة 286 - The sum of the residues at the poles of the last factor, which occurs in (13.18) is therefore equal to minus the sum of the residues at the poles of the other factors.
الصفحة 358 - Since the modulus of a sum is not greater than the sum of the moduli...
الصفحة 96 - In support of such an hypothesis we may remark that as the crystalline grains are built up from their various centres, there will in general be a certain number of molecules to spare between their surfaces ; and these molecules will evidently be distributed in the spaces between the grains with relatively small density, ie, in such a fluid or serai-fluid condition, as would just account for the viscous reaction required.
الصفحة 140 - ... the same properties as the forms upon which they effectively operate, and that the forms which are invariant and the operators are properly to be regarded as one system of forms possessing the same properties.

الصفحة 48 - would prove independent of the length of the rods, provided the velocity and other conditions of the impact were kept unchanged. This was found to be the case, so that, by plotting duration of impact against length of rods, a straight line was obtained, whose slope gave the required value of the wave-velocity. * " On the Effects of Momentary Stresses in Metals,
