It will be seen that in those juice.^ which were analyzed before defe- 

 cation, defecated and allowed to stand on an average of 15 hours, 

 there was no loss of sucrose sustained, and that the average of the 6 

 experiments showed that 83.1 per cent of both the sucrose and glucose 

 present in the juice was recovered in the syrup. 



U^ of Cknj in Defecation. 

 In order to effect the more rapid and complete subsidence of the 

 lime precipitate produced by defecation, it has been the practice of 

 some sugar makers to mix. with the cream of lime, clay or finely pul- 

 verized gypsum (plaster), whiting, sulphate <»f baryta, etc., the object 

 being to entangle in the flocculent precipitate this heavier material, 

 and thus cause its more rapid subsidence. To accomplish this, the clay 

 or other material, is stirred up into a thin cream with water, and mixed 

 in with the cream of lime in proportion so that for each 100 gallons of 

 juice to be defecated there shall be added along with the lime about a 

 gallon of the clay or other cream. After skimming, as usual, the con- 

 tents of the defecator are allowed to stand, to be drawn off as in the
