the sugars. It "appears from these experiments thai in some 

 instances the raw sugars manufactured at great expense by 

 the vacuum process are not superior in point of purity to 

 some sugars exhibited at the Bazar, which were made in the 

 old method. The quantity of atmospheiic moisture absorbed 

 seems to depend, in some measure, on the quantity of uncrys- 

 tallizable matter, or molasses, contained in the sugar. The 

 vacuum raw sugar made at " Pkecnix " contains 15 per cent 

 of molasses, and 7 per cent of moisture absorbed under the 

 ordinary atmospheric pressure and temperature, the Hygro- 

 meter of Sauss:ire being- 74°. The raw sugar of " Queen 

 Victoria " contains 14 per cent of molasses and per cent of 

 moisture. The sugar of " {/wjom," boiled entirely by steam, 

 contains 10 per (ent of molasses and 5 per cent of moisture. 

 There were several sugars manufactured according to the old 

 method, which exhibited similar propoitions with the vacuum 

 sugars, but some were very inferior. The c/uirccd* sugar of 

 " Mount Piton' 1 '' for instance was the purest of the raw sugars 

 tested, containing only 7 per cent of molasses and 2 per cent 

 of moisture. Mr. Pojer observes that however the " tendency " 

 of sugars to absorb moisture from the atmosphere may depend 

 on the quantity of molasses they contain, the proportion of it 

 is not always in an arithmetical progression.
