    Literary! and Philosophical Society, Oct. 6.-Rev. William Gaskell, G?.?., vice-president, in the chair.-On the ossiferous deposit at Windy Knoll, near Castleton, by Mr. Rooke Pennington, LL.B.-On some teeth from a fissure in Water-houses Quarry, in Staffordshire. Mr. Pennington called attention to some teeth of a bison {Bos priscus) from a fissure in a quarry at Waterhouses. The animal had evidently fallen in while coming to drink at the river Hamps. It had been erroneously described as an Irish elk.-On the extent and action of the heating surface for steam boilers, by Prof. Osborne Reynolds, M.A.-Dr. Joule made a further communication respecting his mercurial air pump described in the Proceedings for Dec. 24, 1872, and Feb. 4, Feb. 18, and Dec. 30, 1873. He had successfully made use of the glass plug proposed in the Proceedings for Feb. 4, 1873. This he constructs by blowing out the entrance tube and grinding the* bulb thus formed into the neck of the thistle-shaped glass vessel. To collect the pumped gases he now employs an inverted glass vessel attached to the entrance tube and dipping into the mercury in the upper part of the thistle glass.
