74- Royal Society. 



Lieut.-Col. Sabine, 

 1 have to request of you, when transmitting to M. Regnault this 

 Rumford Medal, to state to him the importance which the Royal 

 Society attaches to his researches, determining with a degree of 

 accuracy hitherto unobtained, the laws which govern the connexion 

 between the temperature and elasticity of saturated steam, and the 

 quantity of heat absorbed by a given weight of water under different 

 densities and pressures. 



The laws which govern the expansion of atmospheric air, under 

 diiferent pressures, and the expansion and densities of different gases 

 and mercury, and the measurement of temperatures by these means, 

 form in a series of memoirs altogether the most important investi- 

 gations hitherto made on this subject. 



Had the philosophical and philanthropical founder of this 

 Medal been now living, I am sure that he would have cordially 

 approved of the award of it to inquiries connected with the most 

 important power that Providence has, as yet, given to man for 

 lightening and assisting his industry, and for giving him speed for 

 crossing sea and land, compared with which, the fabled wings of 

 Daedalus would have been comparatively useless. My only regret 

 on the present occasion is, that M. Regnault is not here himself to 

 receive this Medal. 



The Statutes relating to the election of Council and Officers 

 having been read by the Secretary, and Dr. Royle and Mr. Bennett 

 having, with the consent of the Society, been nominated Scrutators 

 to assist the Secretaries in examining the lists, the votes of the 

 Fellows present were collected.

 being duly elected Officers and Council for the ensuing year: —

 Miller, M.D. ; The Marquis of Northampton ; Richard Owen, Esq.; 

 John Phillips, Esq. ; Peter Mark lloget, M.D. ; the Dean of West- 

 minster; Charles Wheatstone, Esq. 



It was moved by Sir Robert Harry Inglis, Bart., seconded by 

 Mr. Broughton, and resolved unanimously : — 



That on this the last occasion of the Marquis of Northampton 

 occupying the Chair of the Royal Society as its President, the 

 special thanks of the Society be cordially tendered to his Lordship, 

 for his able, zealous, and efficient discharge of the duties of that 

 office for ten years.
