18 THE SPECIFIC HEAT OF WOOD. 



The mean specific heat through any interval of temperature is, under 

 this assumption, of course equal to the true specific heat at the mean 

 temperature. The values given are subject to correction when a 

 large number of runs from different temperatures have been made. 

 They are advanced at the presfent time merely to set forth the best 

 knowledge at hand. 



EFFECT OF STEAMING ON SPECIFIC HEAT. 



The wood used in five runs, Nos. 47, 48, 49, 50, and 51, was placed 

 in the oven at 110 C. while still moist, and dried in nearly saturated 

 air at this temperature. Of these five pieces of wood three showed a 

 greatly increased specific heat. Accordingly it appears possible that 

 exposure to moisture at high temperature increases the specific heat 

 of wood. If this is true, other properties, and with them techno- 

 logical characters, may also change. This behavior needs further 

 study.
