teU upon the proceeds of the boilino-house, I would recommend 

 correcting the cold li(|uor with an alkaline mixture of potash and 

 alum, in equal quantities. These, with the addition of as much 

 boiling water as will hold them in solution, may be added to the 

 temper lime commonly used in plain tempering. 



"Such a measure of this mixture should be added to the 

 liquor in the pan as would be deemed sufficient to correct the 

 prevailing acidity. When the liquor has been boiled into what 

 is called first syrup, it should be racked through the cock. By 

 this timely remedy I have secured well-grained sugar which 

 has not deliquesced during the voyage to Europe, even when I 

 had had the misfortune to have ground tainted canes."
