LOVERING’S EXPERIMENTS. 179 
Further, since 16,530 pounds of juice (1847 gallons, 
weighing 8:95 pounds per gallon) produced but 2114} 
pounds of saccharine matter—the product per acre of 
syrup reduced to the striking point—238° F., could not 
have exceeded 180 gallons, and hence it required 10 gal- 
-lons of juice to produce one of such syrup. These results 
prove that the juice of ripe and unhybridized cane contains 
a varmble amount of sugars and impurities due, in a great 
measure, to peculiarities of soil and season, and confirm 
the conclusion, then reached by analysis, that the quantity 
of uncrystallizable sugar contained in the juice as a natural 
product, and not formed from the cane sugar by the action 
of heat, etc., is comparatively insignificant. 
Mr. Lovering did not repeat his experiments, his object 
being simply to test the value of sorghum as a sugar-pro- 
ducing plant. In a recent letter he says: ‘In the year 
1857, with no other object in view than to satisfy my own 
curiosity, | undertook to ascertain a fact that had been 
denied by some notable chemist, viz.:—the presence of cane 
sugar in the juice of sorghum. The use of Scliel’s sac- 
charometex very speedily proved the fact that it does con- 
tain cane sugar in sufficient quantity to render its extraction 
profitable, and highly important in our Middle and South- 
western States. Having ascertained this truth, I. was 
encouraged to proceed a step further, and undertook the 
experiments, of which I published a detailed account in 
1858.”* 
* It is surprising that Mr. Lovering’s unasserted but just claim to the 
thanks of the public for the faithful performance of an undertaking to 
the success of which he was in no sort pledged, and in which he had 
only a common interest with all men who desire to know the truth, 
should in some quarters call forth only disparagement, or subject him 
to such invidious comparison as is expressed in the following extract 
from a widely circulated advertising pamphlet;
