REPORT OF THE CHEMIST. a paae :5 e 
~ the machines was ‘so thick that it clogged them up. . Seven large 
‘sugar wagons were filled with this material and set in the hot room. 
The sugars made were equal in every respect to those obtained by 
milling in similar instances. Without counting the second sugar 
above named, the grained sugar per ton amounted to 181.5 pounds. 
The grained sugars in wagons will yield not less than 7,500 pounds, 
or 18 pounds per ton.* 
The third sugars are estimated by Mr. Barthelemy at not less than 
16 pounds per ton. 
The total yield per ton of the fifth run will reach, therefore, 215.5. . 
The number of tons of cane used was 417.

COMPARATIVE YIELDS BY MILLING AND DIFFUSION. 
The yield in first or grained sugars affords the best comparison of 
the two systems of manufacture. Judged by this standard the dif- 
fusion process had givena yield of sugar fully 30 pounds per ton 
greater than was afforded by milling. For further data on this point 
see the report of Governor Warmoth farther on. 
CHARACTERISTICS OF DIFFUSION JUICE. 
The juice of diffusion differs from the mill juice chiefly in its con- 
tent of water. In addition to this, also, must be noted a slight in- 
crease in the ratio of glucose to sucrose. This is due doubtless to a 
slight inversion of the sucrose during the process of diffusion. From 
a commercial point of view the loss is insignificant. Further, it may 
be said that there appeared to be in the diffusion juice treated in the |

_ pounds, or 16.8 pounds per ton.
