DR. WETHERILL’S ANALYSES. 183 
It is probable that in all cases in which the cane from 
which these syrups and sugars were made was pure, that 
nearly all the uncrystallizable sugar left in the molasses was 
decomposed cane sugar, resulting from defective means of 
evaporation, want of proper defecation, etc. This is now 
known to be true as respects the uncrystallizable sugar in 
the syrup made from Southern cane, although it was long 
thought to be a natural product, and treated as such. 
The samples of sugar sent to Dr. Wetherill were un- 
equivocally cane sugar, and in most cases exhibited a degree 
of purity equal to that of commercial sugars made from 
the tropical cane and the beet. 
The results of all the foregoing analyses and practical 
experiments, corroborated by my own investigations, made 
with care, during a series of years, fully justify me in 
asserting that there is yet unhybridized Chinese cane in 
this country, containing in the matured juice not less than 
16 or 17 per cent. of saccharine matter, which is nearly . 
all crystallizable cane sugar.
