in the case of loaf-sugar, from France. They differ in no 

 respect from the sugars of European commerce. 



Chemical compost fwn. — The sugar-cane is, when mature, 

 composed of cellulose 8 to 12 per cent,; sugar 18 to 21; 

 water, including albuminous matter and salts, 67 to 73. Of 

 the entire quantity of juice in the cane, from 70 to 84 per cent, 

 can be extracted by crushing and pressing, and jdelds in a 

 crystalline state about three-fifths of the sugar which the cane 

 originally contained. The juice has on an average the 

 following composition ; —

There is also present in the juice a very small amount of a 

 slightly aromatic substance (essential oil?) to which the crude 

 cane-sugar owes a peculiar odour which is not observed in 

 sugar from other sources. [Pharmacographia.) Sugar, 

 (^i»222Qn^ may be obtained in large transparent rhombic 

 prisms, known as mgar-candy, which does not differ from 

 lump-sugar, except that the latter is in crystalline masses from 

 disturbed crystallization. Sugar has the specific granty 1'58 

 (Kopp), is permanent in the air, neutral, without odour, has a 

 very sweet taste, and dissolves at ordinary temperatures in 

 one-half its weight of water, yielding a dense, sweet, and
