Manufacture of Alcohol.—Crystallizations. 107 
mixture employed is oxyd of chrome and carbon, the former in slight 
excess. The metallic chromium resulting was of extraordinary hard- 
ness ; it scratches glass like the diamond. 
Manufacture of Alcohol.—The disease of the vine and the conse- 
quent dearness of wine, has directed attention to different methods of 
finally turn the sugar manufactories into distilleries, we now hear of 
the alcohol of Indian corn, alcohol of couch grass (** chiendent’’), alco- 
hol of asphodel, which have begun to be manufactured in the colony of 
Process. We cannot say that the process will be economical. 
Crystallizations.—We have just seen at the Sorbonne, in the labor- 
atory of M. 
f the magn 
SO°RO4+S0%KO+6HO ; the different alums; the double chlorids ; 
quite Germa M. Dumas employs him in his laboratory and has 
given him a commission to form a collection of the principal artificial 
crystals—an example which should be followed ow crystal- 
cial products should be studied with the care which mineralogists have 
devoted to native crystals. The

avoided when the forms shall have been referred to types whose exact 
Position is known, and whose crystallized form can be verified.
