SPECIFIC HEAT OF GASES.

bination of oxigen with hydrogen. This extraordinary, and, 
at the same time, very important, result, cannot be rejected 
without carrying the influence of these errors, which we may 
possibly have committed in onr determinations, beyond the 
limits which it is reasonable to assign them. 
If, on the other hand, we pay attention to the small sj>ecific 
bent of oxigen gas, we shall perceive, that it becomes very 
diflicult to explain, by a change of specific heat, the heat which 
is disengaged in combustions in general. 
We are, however, far from asserting, that there does not 
exist any connection between the specific heat of a compound, 
ind those parts of which it is componndecl ; this is attested by 
many facts. In truth, we have seen, that hydrogen is of all 
oodies that which has the greatest specific heat ; and also that 
he compound it forms has a specific heat much greater than 
ihat of other bmlies. From hence proceeds the great sp<?cific 
aeat of water, of vegetable and animal substances, of annuo* 
'.ilac, of olefiant gas, &c.
