From a very dilute solution in water, the cobalt salt is precipi- 

 tated by alcoliol in the form of pink flocks. On allowing this 

 precipitate to stand several weeks in the alcoholic fluid, it will 

 be found to liave changed its form, and under the microscope, 

 will be seen to consist of fine needle-shaped crystals. These 

 crystals dried at 100° C. gave by analysis the formula : CgH, , 

 CoO.+H^O.

Manganese Salt — A solution of the acid treated, as in the 

 preceding methods, with manganic carbonate, forms a soluble 

 manganese salt which separates from the suitably concentrated 

 fluid in masses of fine microscopic feather-like crystals. These 

 crystals upon close examination are seen to be made up of ra- 

 diating needles. When agitated in water they have a brilliant 

 silky luster. They are slightly yellow, soluble in water, but 

 insoluble in alcohol. The salt dried at 100° C, gave by analysis 

 the formula: C,H, ,MnO,. 



I. 0-305 grams of the salt dried at 100° C, gave -362 grams 

 Cog and -142 grams HgO. 

 II. 0-353 grams of the dried salt gave -062 grams MugO^-
