116 Some Experiments on the Distillation 



sume to advance further, T perhaps may assist in clearing 

 the way for future naturalists, and, by establishing effects, 

 encourage them to proceed to causes, and help them to dis- 

 cover the powers and agents by which these grand opera- 

 tions have been executed.

Experiment XXI II. 



JJittfr Almonds, 240grains. — In distillation they discharged 

 a great quantity of smoky flame. The. almonds were found 

 without adhesion to each other, and contained upon their 

 surface a great variety of prismatic colours. The coal was 

 found to weigh 32 grains : 208 grains having been lost by 

 the distillation. 



Component parts : Volatile matter 80*66 

 Oxide of carbon 10/34: 



100 parts. 



Experiment XXIV. 

 Black Pepper, not ground, 240 grains. — In distilling, i 

 considerable portion of flame was disengaged. The coal ob- 

 tained was partially prismatic. Every spherule of pepper 

 preserved its original form. A few masses slightly adhered 

 together without any appearance or reality of welding. 

 Weight of the coal 53 grains. Loss by distillation 187 grs. 

 Component parts : Volatile matter 77*91 

 Oxide of carbon 2209 



100 parts. 



Experiment XXV. 

 White Pepper, 240 grains. — This substance flamed a good 

 ileal in distilling, of a pure white colour, edged with pale 



blue.
