I. Result of some Experiments on the Distillation of va- 

 rious Vegetable and Animal Substances in the dry Way* 

 By David Mushet, Esq. 



J. he following are some of the experiments promised in 

 my last communication to the Philosophical Magazine*. 



Experiment I. 



Haw Sugar. — 270 grains, being distilled till all volatile 

 matter was separated, were found to have been reduced in 

 weight to 38 grains, having lost 232 grains. 



100 parts therefore contained: Volatile matter 85*9 



Oxide of carbon 14*1 



The charcoal obtained in this experiment was light and 

 spongy, and possessed the most fascinating prismatic co- 

 lours ; gold, purple, blues, and indigos. It occupied about 

 three times the bulk it possessed when raw. 



Experiment II. 

 Loaf Sugar , single refined, 264 grains. — This in distilla- 

 ion also swelled greatly in bulk, and discharged a pure 

 white flame edged with blue. The coal had in forming en- 

 tered into complete fusion, and resembled the former pro- 

 duct, though not possessed of the same brilliant shades. — 

 It weighed 39 grains. Loss by distillation 225 grains. 

 Component parts of loaf sugar : Volatile matter 85*26 



Oxide G*" carbon 1 4* 74 



100 parts. 



From these experiments it is evident that sugar possesses
