(shin bone of beef) on the false bottom or shelf within the 

 beurette, and pour the syrup over the charcoal, which is to be 

 beaten up fine, letting it drain through the funnel-head, 

 this will be molasses, the grains of sugar being left on the 

 surface of the charcoal, which scrape off. Then, to dry the 

 sugar, put it into a pan, and place in " water-jacket" ; i.e., a 

 square iron box, double, a space of two inches for water on 

 each of three sides ; the fourth is the door to one shelf in the 

 middle, and the bottom forming another, on which shelves 

 the sugar is placed, being completed by a closed door. Make 

 a fire of vegetable charcoal on bed of sand, placing in the hot 

 water. Place the " water-jacket" upon it until the sugar is 

 dried. There is a valve on the top for escape of moisture. 

 The object is equal temperature. Thus, sand, charcoal, water, 

 shelves, sugar." 



It had been my first intention to try this experiment myself 

 on a small scale before submitting any communication to the 

 Eoyal Society ; but deferring to the suggestion made to me 

 at a meeting of the Council this afternoon, I at once lay the 

 process before the Society for trial, to enable any one willing 

 to test it. 



I will only add, in conclusion, that the Agricultural Society 

 of IN'ew South Wales has a periodical for the publication of 

 its transactions and correspondence ; and that I had the 

 pleasure, through a gentleman, of establishing relations 

 between that Society and the Eoyal Society of Tasmania in 

 the exchange of its papers. The first supply will, I expect, 

 arrive by the next steamer from Sydney.
