Bromide of samarium 



SmBr, + 6H2O. 



On evaporating, over sulphuric acid, a solution of oxide of sa- 

 marium in hydrobromic acid, to the consistency of a syrup, large, well 

 developed, topas-yellow crystals are deposited, which resemble in form 

 crystals of gypsum. There crystals are very deliquescent and when 

 heated give off water and hydrobromic acid, even though mixed with 

 excess of ammonium bromide. The whitish residue leaves on treatment 

 with water, brilliant micaceous crystals, probably of an oxybromide, 

 which are slowly attacked by acids. 



0.7634 gram of the crystallised bromide, pressed between paper, 

 gave 0.8540 gram AgBr and 0.2662 gram SmgOg.

Chloroplatinate of samarium 



SmCla, PtCl4+10V,H,O. 



By slowly evaporating mixed solutions of the simple chlorides, large 

 prismatic crystals of deep orange colour are obtained. The chloro- 

 platinate is easily soluble and deliqvescent. It looses at 110" about 

 4 mol. H2O.
