Mi;. J. H. GRINDLEY ON AN KXI'KIMMKNTAl, 1NVKST1C ATIOX OF 



TABLE IV. (continued). 



That a large variation in the value of the specific heat takes place with temperature 

 is clearly shown in the last column of this table ; its variation with pressure is uot, 

 however, quite so evident. To enable a simple comparison to be made, certain figures 

 are taken from the above table which show the values of the mean specific heats 

 under different pressures but near the same temperature. These are placed in the 

 following Table V., and the comparison this table affords shows very clearly that if 

 there is any variation in the value of the specific heat at constant pressure with 

 pressure it must be very small, especially when viewed in comparison with the 

 variation with temperature as shown by the previous table.
