Experiment XXXVIII. 

 AToad, weighing 554 grains. — This was introduced into a 

 retort, and distilled with nearly the same attendant circum- 

 stances as in the experiments immediately before. At the 

 commencement of the operation a violent hissing was per- 

 ceptible, accompanied with slight explosions. The result 

 was, the skeleton nearly in the position in which it was ori- 

 ginally placed. The flesh and skin had disappeared, and left 

 a very perfect coal adhering to the bones, all of which were 

 converted into a beautiful white colour,^ — The carbonaceous 

 matter weighed 94 grains ; the bones, some of which soon 

 fell into powder, 7 grains : — total 31 grains. Loss in the 

 distillation 523 grains.

Experiment XXXIX, 

 An Eel, weighing 704 grains, and newly killed, was boil- 

 ed up and put into the retort, and exposed till all smell of 

 animal had ceased. A mass of coal was found attached to 

 the slender bones of the animal, and in the same position it 

 originally occupied. It was not easily possible to separate 

 the bone. The whole weighed 28 grains, having lost in 

 distillation 676 grains.

Experiment XL. 



While Snails, 340 grains. — These in distillation formed 

 a pretty firm mass of caked coal of a dull black colour. The 

 same penetrating smell of animal matter was perceived in 

 this experiment as in the former. The coal weighed 21 

 grains - 9 319 grains having been lost by distillation.
