" 111 the experiments by me, during the winter of 1855, 

 I was forcibly struck with the better quality of the juice 

 grown in our section of the country, as compared with that 

 experimented upon by Mous. Yilmorin. He gives the den- 

 sity of his sap at 1-050 to 1-075, while that examined by 

 myself was uniformly found to be 1-085, with but little va- 

 riation, and in every case some small corrections for tem- 

 perature, which would increase the specific gravity slightly. 

 The average density given by various observers in the 

 West Indies, of juice from the several varieties of sugar 

 cane grown in these colonies, is about nine degrees Baume, 

 corresponding to a specific gravity of 1-0G4, — less, consid- 

 erbly, than mine. From this fact, however, it is not to be 

 inferred that the juice of our cane abounds more largely in 

 saccharine matter than that of the West Indies ; for such 

 probably is not the fact ; for the former is known to con- 

 tain a larger proportion of salt and vegetable matters than 

 the latter. It argues only the remarkable adaptation of 

 the Chinese cane to our climate and soil. M. Vilmorin 

 obtained from this 'sap' of the densities named, from 

 1-050 to 1-075, on the 



13th of October, 1853, 10-04 per cent, saccharine matter.

" Of the latter, 11-75 were uncrystallizable, and but 4-25 



of the crystallizable variety. M. Avequin obtained from

I have not been able to compare these experiments with 

 similar results obtained here. I propose doing so the 

 coming tieason. M. Vilmorin estimates the per ceutage
