The analysis gave 0.6 percent samarium too little, which may be 

 ascribed to the extreme hygroscopicity of the salt. 



Sulphocyanate of samarium 



with 



Cyanide of mercury 



Sm(CNS)3 + 3Hg(CN) + 12H,0. 



The mixed solutions of the simple salts deposit on cooling elon- 

 g'ated, often asbestous-like needles, which are easily soluble in hot water. 



0.5182 gram lost on heating to 100° or 110" 0.0835 gram HgO. 



0.5115 gram was dissolved in water, acidulated with hydrochloric 

 acid, and the solution precipitated with H2S. Thus obtained 0.2783 gram 

 HgS, and from the filtrate 0.0700 gram SmaOg, precipitated as oxalate.
