I H TI IIMINATIVI: TABLE (ill) 



VI. The powdered mineral is dissolved iti nitric :icid, or if 

 insoluble it iv I'u-ed with >oda, then di olv.-d ; t IK- solution treated 



with aniinoiiiiiiii molybdate yields a yellow precipitate (phosphoric 

 acid): p. 653. 



VII. The powdered mineral heated on coal in the R. F. lx>comes 

 magnetic; p. 657. 



\ III. After intense ignition in the forceps, it yields an alkaline 

 reaction with turmeric paper. Hardness below 5; p. 660. 



IX. Fused with Turner's flux it yields a green flame (boric acid) ; 

 p. 663. 



X. The powdered mineral when dissolved in the borax bead in 

 the O. F. is violet-red when cold (manganese) ; p. 665. 



XL The mineral is well powdered and fused with borax, dis- 

 solved in concentrated HC1, then boiled with tin ; the solution is 

 violet in color (titanium) ; p ; 667. 



XII. Treated as in XI, but the borax bead is powdered, dissolved 

 in dilute HC1, and zinc added ; the solution becomes blue (tung- 

 sten) ; p. 668. 



XIII. The mineral in powder is dissolved in S. Ph. 



A. The bead is yellow in R. F. when cold ; p. 669. 



B. The bead is blue in both flames ; p. 669. 



C. The bead is green in R. F. when cold ; p. 669.
