It would appear by the Experiments from Ex per. XIII, 

 inclusive, with the exception of the gunpowder tea, that the 

 coajs obtained from these various substances do not con,^. 

 tain the welding or caking principle ; and so far they re-- 

 semble the residual coals, or oxides obtained from the di- 

 stillation of all the woods. 



The following experiments are selected from a variety 

 made with animal substances. 



Experiment XXXII. 

 Beef, entirely freed from fat, 1121 grains.-r-This in distil- 

 lation gave out a light blue penetrating smoke, which to- 

 wards the middle of the operation became particularly of- 

 fensive. Towards the close a blue lambent flame appeared, 

 which continued to twitter for some time ; after this, all of- 

 fensive smell ceased, and a skeleton coal of a pure black 

 colour was obtained perfectly insipid, which weighed 34. 

 grains ; 1087 grains having been lost by distillation.

100 parts. ■ 



Experiment XXXIII. 

 Fat, cut from the same beef, 425 grains. — This was slowly 

 distilled, and with a moderate heat, so as to restrain the 

 flame. After ignition there was found in the bottom of the 

 retort a long flake of carbonaceous matter that weighed three 

 grains. Loss by distillation 422 grains.
