TABLE 1 OF REDUCING VALUES OF VARYING QUANTITIES OF DEXTROSE, LEVULOSE AND 

 INVERT-SUGAR UNDER THE STANDARD CONDITIONS GIVEN ON PAGE 227. 



(Adopted by Brown, Morris and Millar, " Journal of the Chemical Society," 1897, 



vol. Ixxi., p. 281.) 



The sugar values for weights of Cu or CuO lying between any of the weights given in 

 the above table must be arrived at by calculation. 



Example. The amount of dextrose corresponding with '2385 grm. Cu is required. 

 On referring to the table -2313 grm. Cu corresponds with -115 grm. dextrose; and '2404 

 grm. Cu with -120 grm. dextrose. Hence -2404 - '2313 = *oogi grm. Cu ; and -120 - -115 

 = -5 g rm - dextrose. Therefore '0091 grm. Cu = '005 grms. dextrose in the portion of the 

 table used. Now the difference between the amount of Cu found, '2385, and the nearest 

 lower amount in the table, -2313 grm. is -0072 grm. Hence: -oogi : '005 : : -0072 : '004. 

 Therefore -115 + -004 = -ng grm. dextrose corresponding to -2385 grm. Cu.
