ON MAGNESIUM. BY M. BUSSY. 



When M. Wohler published his process in 1828 for the separation 

 of the metal of alumina by means of the decomposition of the chlo- 

 ride of aluminum by potassium, M. Bussy judged from analogy that 

 glucinuni might be separated from its chloride by a similar process : 

 the results confirmed his opinion ; and since this period he has suc- 

 ceeded in separating magnesium from its chloride. To prepare this 

 chloride, equal parts of starch and calcined magnesia are to be mixed 

 with a small quantity of water, the mass is to be divided into small 

 portions, and strongly calcined in a crucible without the contact of 

 the air. This mixture is to be afterwards put into a porcelain tube, 

 and a current of chlorine pavsed over it, at a red heat. After some 



time.
