the sirup; the other mechanical, having for its object to 

 separate from the same, the carbon and other solid bodies 

 agglomerated by the albumine. 



The first is managed with a boiler, only because the ac- 

 tion of the chemical agents employed require to be aided 

 by heat. 



01 all the means hitherto devised for clarification none 

 has been found so simple and so effective as that offered by 

 the use of animal carbon, and albuginous or caseous mat- 

 ter. 



*We will here suppose that the object in view is to clarify 

 the portion of sirup supplied by the defecation of 100 gal- 

 lens of juice, that is 16 1-2 gallons of sirup concentrated to 

 26° boiling and 30° cold, (it follows that for any other quan- 

 tity is is only required to follow the same proportion) to do 

 this we must proceed to weigh 8 pounds of animal carbon 

 and throw it into the boiler, the sirup when boiling should 

 be well stirred with the ladle, then with the skimmer, the 

 black agglomerated matter which rises to the surface should 

 be broken up and mixed again with the liquid ; when it is 

 apparent that the carbon is sufficiently separated and mix- 

 ed with the sirup, it may be left to boil for a few minutes. 

 The sirup now assumes a turbid and murky appearance ; 

 whilst this operation is proceeding a quart of ox blood, or 

 the white of 4 eggs should be beat up and diluted with wa- 

 ter, or otherwise two quarts of skimmed milk. This mixture 

 must now be thrown into the boiler, taking care to mix the 

 whole well together. The ebullition w^ill of course have 

 been stopped by this addition, and it is proper till it begins 



* The process we are about to describe is varied by different man- 

 ufacturers, by some the acid is omitted altogether and other agents 

 substituted.
