The author gave an account of the analysis of the vege- 

 table alcaloid thebaine (paramorphine) which had been dis- 

 covered in opium, and of which the analysis by Pelletier and 

 Couerbe gave discordant results. With a specimen which 

 had been prepared by Apothecary Merck of Darmstadt, 

 Dr. Kane obtained the formula C 25 N 2 H 28 O a , (Berzelian 

 atoms,) and giving the per cent, composition: 



25 Carbon = 74,57 = 1910,925 



2 Azote - 6,89- 177,036 

 28 Hydrogen = 6,83- 174,714 



3 Oxygen =11,71- 300,000 



100,00 2562,675 



Owing to the circumstance of the salts of this base with the 

 mineral acids being uncrystallizable, the atomic weight ob- 

 tained by analysis could not be synthetically confirmed. 



Professor Kane read likewise an extract of a letter from 

 Professor Liebig, of Giessen, communicating some new re- 

 sults of chemical analysis. 



It was resolved, on the recommendation of council, that 

 the bye-laws relating to the meetings of the Academy and 

 Council (Chap. IV. Sects. 2 and 6), be altered, and the fol- 

 lowing substituted : — 



(2.) "That a General Meeting of the Academy shall 

 likewise be held on the second Monday of November and 

 December, and on the second and fourth Mondays of Ja- 

 nuary, February, April, May, and June, at 8, p. m. At 

 these Meetings, such communications as shall have been 

 approved of by the Committees during the preceding part of 

 the month, shall be read." 



(6.) "That the Stated Meetings of the Council shall be 

 held on the first and third Monday of every month, from 

 November to June, inclusive ; with power to adjourn, from 

 time to time, at all times of the year. Five to be a quorum."
