The following Tables (VIII. and IX.) show the numerical results of the investigation 
now under consideration :— 
Taste VIII.—Showing the conditions provided in Experiments on the Decomposition 
of Nitrogenous Organic Matter; and the amount and proportion of the original 
Carbon of the substance remaining after the decomposition, or given off during the 
process.

A comparison of the results in Tables VII. and LX. will show that they are confirma- 
tory of each other as to their more general indications. Both series agree in the entire 
absence of any tangible relation between the varied circumstances of decomposition, and 
the products of that decomposition.
