118 Dr. A. vou Planta on the Constitution of Bebeerine. 



Dried at 250° and burnt with chromate of lead, it gave the 

 following results : — 



I. 4-269 grs. platinochloride of bebeerine gave 6-890 grs. car- 

 bonic acid and 1-735 grs. water. 



II. 6-665 gi-s. platinochloride gave 10-775 grs. carbonic acid 

 and 2*752 grs. water. 



III. 9-020 grs. platinochloride gave 14-580 grs. carbonic acid 

 and 3584 grs. water. 



IV. 8-280 grs. platinochloride gave 13-477 grs. carbonic acid 

 and 3-258 grs. water. 



I. 7-823 gi-s. of platinochloride, which had been precipitated 

 from an alcoholic solution of bebeerine, gave 1-502 platinum. 



A platinum salt precipitated from an aqueous solution gave — 



II. 9-38 platinum salt gave 1-765 platinum. 



III. 8-333 platinum salt gave 1-572 platinum. 



100-00 517-2 



The formula of the platinochloride is consequently — 

 C38 H21 N 06 HCl, Pt CP. 



The equivalent of the platinum compound calculated from the 

 above determinations of the platinum, gives in the first instance 

 514-6, that of bebeerine itself 309-4; in the second, 524-5 and 

 319-3; in the third, 523-2 and 318-0. 



Drs. INIaclagan and Tilley obtained for the platinum salt the 

 following numbers : — 



498-2
