cumstances, é&c. under which the analyses were made. McCulloh 
asserts that a saturated solution at 212° Fah., will contain 80 p. ec. 
of cane sugar, 50 of which will crystallize. 
he matter has excited considerable interest on the part of the 
government from the fact that it has been said, that nearly pure 
syrups have been imported by refiners under the name of mo- 
lasses; and that the resulting refined sugars have been exported 
under the privilege of the drawback. ‘These syrups (sirops de 
batterie) contain, according to McCulloh, 60 p. c. of cane sugar, 
and may be so disguised as to render it difficult to distinguish 
them from molasses. 
_Texamined with the instrument before mentioned, several sam- 
ples of molasses imported from the West Indies, which Dr. E. H. 
Barton, Inspector of drugs and chemicals, brought from the cus-
