OCCULTATION OF SATURN, OBSERVED AT GENEVA. 

 This phaenomenon, which took place on the 8th of May, was ob- 

 served by M. Gautier with the Dollond's telescope described in the last 

 Number of Phil. Mag. p. "246. The same clock was used, but it was 

 now only three seconds and a half fast. h m s

At the end of the emersion, M. Gautier observed that the light of 

 Saturn was then singuliniy pale and of a grayish-green colour, "' from 

 the effect of the lustre of the illuminated limb from which the planet 

 emerged."— £i6L Univ. April 1832. 



NEW PROCESS FOR OBTAINING MORPHIA. 



M. Ant. Galvani has proposed a new method of obtaining mor- 

 phia directly from opium, free from narcotine: — Evaporate to the 

 consistence of an extract a spirituous solution of opium ; then, by 

 successive solutions and filtrations, separate all the resinous matter 

 of the extract, which separates the narcotine from the morphia: long 

 ebullition with calcined magnesia, — a series of filtrations, and wash- 

 ings and dryings, yield very pure morphia, free from narcotine. 

 When the resinous matter is dissolved in dilute sulphuric acid, and 

 the solution decomposed by potash, the narcotine is precipitated, 

 which is purified by a fresh solution in sulphuric acid and precipi- 

 tation by anmionia, and this often, after filtration, washing and re- 

 dissolving in alcohol of 0'90o, crystallizes. A pound of opium 

 yielded by this process 8 drachms of perfectly pure white crystal- 

 lized morphia. — Ann. de Chiin. et de Phys. torn, xlviii. p. 297.
