A third Table is annexed, which may be found practically useful. It contains 
the results of the empirical formulz (2.) and (3.), for every tenth degree of the 
centigrade scale from 0° to 260°. 
The column headed ee shews the ratio of the specific heat at T to the specific 
0 
heat at 0°. That headed = n 
0 
_ 0 and T to the specific heat at 0°. 

shews the ratio of the mean specific heat between 
1 Opt ; : A 
The column headed j- i. K dT shews the ratio of the heat required to raise 
°F 0 
_a given weight of water from 0° to T, to the heat required to raise the same weight 
of water from the temperature of maximum density to one degree above it.
