Sir JOSEPH LISTER, Bart., President, in the Chair
Lieut.-Colonel Sir G. S. Clarke and Professor H. A. Miers were admitted into the Society.
A List of the Presents received was laid on the table, and thanks ordered for them
Sir J. W. Dawson exhibited new specimens of Carboniferous Batrachians.
An oral communication was made by Professor J. A. Fleming, F.R.S., on behalf of Professor Dewar and himself, to the following effect:-
In continuing our experiments on the electrical resistance of bis muth at low temperatures and in magnetic fields, by the aid of a powerful electro-magnet, kindly lent to us by Sir David Salomons, we have observed the fact that a wire of electrolytic bismuth, when cooled in liquid air to a temperature of increased more thau forty-two times if it is at the same time trans versely magnetised in a field of 14,000 units. The bismuth, when cooled in liquid air and thus magnetised, has its electrical resistance iucreased more than fifteen times, even when compared with its resistance at ordinary temperatnres and not in a magnetic field. There is no reason to believe we have reached the lmits of this increase Royal Society later.
