Oxygen 6 oz. 3 gros. 66.34 grs. = 3738.34 grs.
Azote 1 5 25.82 = 961.82.

By this we find that, during the above deslagration, 2 gros 1 gr, of charcoal have suffered combustion, alongst with 3738.34 grs. or 6 oz. 3 gros 66.34 grs. of oxygen. Hence, since 12 libs. of ice were melted during combustion, it follows, that one pound of oxygen burnt in the same manner would have melted 29.58320 libs. of ice. To which the quantity of caloric, retained by a pound of oxygen ager combining with charcoal to form carbonic acid gas, being added, which was already ascertained to be capable of melting 29.13844 libs. of ice, we have for the total quantity of caloric remaining ina pound of ixygen, when combined with nitrous gas in the nitric acid 58.72164; which is the number of pouinds of ice the caloric remaining in the oxygen in that state is capable of melting. We have before senn that, in the state of oxygen gas, it contained at least 66.666667; wherefore it follows that, in combining with azote to form nitric acid, it only losses 7.94502. Farther experiments upon this subject are necessary to ascertain how far the results of this calculation may agree with direct fact. This enormous quantity of caloric retained by oxygen in its combination into nitric acid, explains the cause
