that is of considerable importance, for the weight 

 of the gallon of proof spirit that exists at 80 deg. F., 

 weighs only 9.109 lbs. The difference in the definition 

 between the gallon of water and the gallon of proof 

 spirit is, that, in the case of water, it is that volume of 

 water that weighs 10 lbs. at 62 deg. F., while in the 

 case of spirit it is the gallon of spirit that at 51 deg. F. 

 weighs 9*2366 lbs.

It will be noticed that 100 parts sucrose produce 105 '36 

 in different bodies ; as in the invertion of the cane 

 sugar, water (or the elements of water) is assimilated, 

 and the solution becomes denser. 



If, therefore, a wash be set up with sugar at a density 

 of 1060, the density will increase to 1063 before 

 attenuation sets in. Which of these is the true " originate" 

 density ? If the first, then the 3 deg. extra cannot be 

 claimed, nor its production of 0*47 gallon proof spirit per 

 100 gallons wash. And if the second, the question may 

 arise, when is the density of the wash to be taken ? 



The same weight of sucrose or glucose will set wash 

 at the same density, but the return in the first case will 

 be much higher than in the second. To put it in 

 popular terms, suppose two vats set up at 1060, A. with 

 sucrose, and B. with glucose, and they both completely
