172 III. COMPOUND COMBUSTIBLES.— 



Dantzic brandy. From rye ground with the root of Cala- 

 mus aromaticus, which gives it a mixed flavour of orris and 

 cinnamon. 



Rum. From the refuse of the raw sugar-manufactories, by 

 taking equal quantities of the skimmings of the sugar-pans, of lees 

 or returns, as they are commonly called, and of water ; and to 100 

 gallons of this wash are added 10 gallons of molasses ; this affords 

 from to 10 to 17 gallons of proof rum, and twice as much low 

 wines. — Double-distilled rum. Is rum rectified to a strength ap- 

 proaching to spirit of wine. 



Sugar spirit. From the washings, skimmings, and other 

 waste of the sugar-boilers : it is a very pure spirit, and used to 

 mix with brandy. 



Cane spirit. From the juice of the sugar-cane. 



Molasses spirit, Spiritus ex syrupo^ P. L. 1745. Is obtained 

 from molasses, or treacle, by mixing S or 3 gallons of water with 

 each gallon of molasses, and to every 200 gallons of this mixture 

 adding a gallon of yeast ; once or twice a day the head as it rises 

 is stirred in, and in three or four days, 2 gallons more of water is 

 added to each gallon of molasses originally used, and the same 

 quantity of yeast as at first : four, five, or six days after this, there 

 is added a third portion of yeast, as before, on which the fermen- 

 tation proceeds with great violence, and in three or four days the 

 wash is fit for the still : 100 gallons of this wash is computed to 

 yield 22 gallons of spirit, 1 to 10 overproof.

 tatoes, \ a cwt. of malt, hot water added in three portions, in
