analyses of the Ashes of Rough Brown Sugar and Molasses. 337 



Omitting the carbonic acid and combining the chlorine with 

 the sodium and potassium, we obtain the following composition 

 in 100 parts: — 



Potash 19*42 



Lime 14.-67 



Magnesia 10'72 



Peroxide of iron .... 6'55 

 Oxide of copper .... '71 

 Oxide of manganese . . . trace 

 Chloride of potassium . . . 8'03 

 Chloride of sodium . . . 15*46 



Sulphuric acid 10'85 



Silica 13-59

II. Molasses. 



Great dijfficulty was experienced in incinerating the bulky 

 charcoal mass left by boiling down the molasses. Part of the 

 oxide of iron and sulphuric acid were decomposed ; and this 

 accounts for the excess in the analysis, as these substances 

 were obviously in part twice estimated. 477'77 grs. left 17*21 

 grs. ash =3*60 per cent. 



64*27 grs. of ash furnished 6*46 grs. carbonic acid. 



64*27 grs. of ash furnished 8*65 grs. charcoal, containing 

 '55 gr. peroxide of iron and *26 gr. lime. 



64*27 grs. of ash furnished 1*02 gr. silica. 



21*423 grs. of ash furnished "28 gr. peroxide of iron. 



21*423 grs. of ash furnished 3*83 grs. C02CaO = 2-14grs. 

 lime. 



21 -423 grs. of ash furnished 5*34 grs. PO5 2MgO= 1 -95 gr. 

 magnesia. 



21*423 grs. of ash furnished chlorides of alkalies 14*91 grs., 

 and this gave chlorides of platinum and potassium 32*88 grs. 

 = Cl2 K 10*34 grs., leaving ClgNa 4*57 grs., = potash 6*53 and 

 soda 2*42 grs. 



12-62 grs. of ash furnished 2*38 grs. SOgBaO =*818 gr. 

 sulphuric acid. 



18*405 grs. of ash furnished 9*92 grs. Clg Ag=2*453 grs. 

 chlorine. 



The ash also contained traces of oxides of copper and man- 

 ganese. 



Collecting these results we obtain the following composition :
