LONDON Mathematical Society, November 10.—Sir J. Cockle, F.R.S., President, in the chair.—Prof. Sylvester, F.R,S., being incapacitated by an accident to his leg from attending in person to receive the De Morgan Medal, awarded him by the Council in June last, deputed Mr. J. Hammond to represent him. The President, after a few remarks eulogistic of Prof. Sylvester's numerous discoveries, presented the medal to Mr. Hammond, who made a felicitous reply.—The Treasurer (A. B. Kempe, F.R.S.), after having read his Report, announced to the meeting that the Society's application to the Privy Council for the grant of a charter had failed.—The following were elected to act as the Council for the ensuing session:—President: Sir J. Cockle, F.R.S. Vice-Presidents: Dr. J. W. L. Glaisher, F.R.S., Prof. Hart, and Lord Rayleigh, Sec.R.S. Treasurer: Mr. A. B. Kempe, F.R.S. Hon. Secs.: Messrs. M. Jenkins and R. Tucker. Other Members: Messrs. A. Buchheim, E. B. Elliott, A. G. Greenhill, J. Hammond, J. Larmor, C. Leudesdorf, Captain P. A. Macmahon, R.A., S. Roberts, F.R.S., and J. J. Walker, F.R.S.—The following communications were omade:— On pure ternary reciprocants and functions allied to them, by E. B. Elliott.—On the general linear differential equation of the second order, by the President.—On the stability of a liquid ellipsoid which is rotating about a principal axis under the influence of its own attraction, by A. B. Basset.—On modular equations and geometry of the quartic, by R. Russell.—The differential equations satisfied by concomitants of quantics, by A. R. Forsyth, F.R.S.—On the stability or instability of certain fluid motions (ii.), by Lord Rayleigh, Sec.R.S.—Notes on a system of three conies touching at one point, by Dr. Wolstenholme.
