that the experiments of Lavoisier were more 
to be depended upon. At least, the above con- 
clusions of Dr. Bostock, and the account which 
Mr. Murray has given m his Chemistry, 1807, 
seem to warrant the observation. The last 
gentleman adopts the proportion’ of 84 ‘aia

In the Phil. Transac. for 1807, aaani 
‘Allen and Pepys have given a very excellent 
paper on the quantity of carbone in carbonic 
acid, and on the nature of the diamond. (See 
also Nicholson’s Journal, vol. 19, 1808.) 
These authors, to all appearance, indisputs 
ably confirm the results of Lavoisier, in re> 
gard to the constitution of carbonic ‘acid; 
namely, that it is a compound of 28° parts of 
carbone by weight, and 72 of oxygen, or very 
nearly so; and that carbonic acid contains 
just its own bulk of oxygen. 
The Phil. Transac. for 1808» (or Nichol- 
son’s Journal, vol. 22.) contain’a very labori- 
ous, and apparently, accurate series of experi- 
ments on respiration, by Messrs. Allen and 
Pepys. After a great number of experiments, 
made under advantageous circumstances, with 
the experience of previous enquiries before 
them, and with improved methods of analysis,
