The Royal Society . — The annual meeting of the Fellows of this society 
was held on November 80, at Burlington House. The President, Lieut.- 
General Sir Edward Sabine, K.C.B., See., delivered the inaugural address, 
in which he reviewed the progress which had been made in science during 
the year. In closing his address Sir F. Sabine announced his intention not 
to offer himself for re-election at the next anniversary, when, to quote his 
words, he “will deliver over the chair, doubtless to a younger, it may well 
be to a worthier, occupant ; it can hardly be to one having the welfare of 
the Royal Society more warmly at heart ” — a sentiment which was cor- 
dially echoed by all present. The presentation of the medals followed : — 
The Copley Medal was awarded to Mr. James Prescott Joule, F.R.S., for 
his experimental researches on the dynamical theory of heat,- a Royal
