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,, N, H,, O,, (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.”
