It is then placed in " vacuum pans," and boiled, at 

 a low temperature, until crystallization commences, 

 or is effected ; and pure white sugar is secured by- 

 placing the crystals in drying-rooms heated by 

 steam. 



It is quite impossible, in a paper necessarily so 

 brief as this, to touch upon very many important 

 points connected with the chemistry of sugar. 

 Perhaps at another time the subject may be re- 

 sumed, and a larger number of interesting facts 

 presented.
