Abstract
A study of the published determinations of the capacity for heat of the elements leads to the conclusion that further information of an accurate nature is desirable. It will be found that, in most cases, the values are deduced by observations of the heat absorbed or given out when the changes of temperature are large, and the conclusions derived therefrom are based on the assumption that the relation between the specific heat and the temperature is of a linear order. Again, some, in fact a large majority, are comparative determinations and dependent on the capacity for heat of other bodies, as, for example, those which assume Regnault’s values for the capacity for heat of water at ordinary temperatures—values which we now know to be inaccurate.
