[Footnote 2: When one temperature alone is given the "true" specific
heat is given; otherwise the value is the "mean" specific heat for the
range of temperature given.]

[Footnote 3: For variation, see Table 13.]

[Footnote 4: Where range of temperature is given, coefficient is mean
over range.]

[Footnote 11: 460 degrees below the zero of Fahrenheit. This is the
nearest approximation in whole degrees to the latest determinations of
the absolute zero of temperature]

[Footnote 15: Some waters, not naturally acid, become so at high
temperatures, as when chloride of magnesia decomposes with the formation
of free hydrochloride acid; such phenomena become more serious with an
increase in pressure and temperature.]

[Footnote 21: The actual specific heat at a particular temperature and
pressure is that corresponding to a change of one degree one way or the
other and differs considerably from the average value for the particular
temperature and pressure given in the table. The mean values given in
the table give correct results when employed to determine the factor of
evaporation whereas the actual values at the particular temperatures and
pressures would not.]
