Dec. 8. — A paper was read, entitled, Additional proofs of the 

 source of Animal Heat being in the Nerves. By Sir E. Home, 

 Bart. V.P.R.S. 



This paper contains the account of a repetition of the author's 

 former experiments, upon the effects of dividing the nerves sup- 

 plying the velvet of the deer's horn, in which the same results 

 have been obtained ; while some exceptionable parts of the former 

 proceedings have been carefully avoided. It was now found, as 

 before, that immediately upon the division of the nerves of one 

 horn, the temperature of that horn was diminished sometimes to 

 the amount of 7°, and that in the course of tei; or twelve days, the 

 disparity of temperature between the two horns began to cease, 

 and they ultimately again attained precisely the same temperature. 

 When this had taken place, the deer was killed, and the parts 

 were carefully dissected and examined; when it was found, that 

 the interval occasioned by the recession of the divided nerves, was 

 filled up by a newly-formed substance, which firmly connected 

 them ; and this explained the restoration in their functions, which 

 had taken place. 



In further proof of the influence of the nerves over the evolution 

 of heat, independent of mere sauguineous circulation, Sir Everard 

 adverts to a case of aneurism, in which he tied the femoral artery 

 immediately below Poupart's ligament. The obstruction of this 

 large arterial trunk, however, did not occasion any diminution of 

 temperature in the foot, below the natural standard. 



Dec. 15. — The President announced to the Society His Ma- 

 jesty's munificent foundation of two annual prizes, consisting each
