 8th edition, rewritten in iqog. Calorie used is heat required to raise i Kg. water from 15° to 16° C. B. T. U. is heat 

 required to raise i pd. water from 62'^ to 63^ F. Mechanical Equiv. of heat used, 77S ft. pds. or 427 m. Kg. Specific 

 heats, see Harnes-Kegnault-Peabody results, p. 227. Heat of Liqiiid, q. heat required to raise i Kg. (i lb.) to corre- 

 sponding temperature from 0° C. Heat of vaporization, r. heat required to vaporize i Kg. ( 1 lb.) at corresponding tem- 

 perature to dry saturated vapor against corresponding pressure; see Henning, Ann. der Phys., 21, p. 849, 1906. Total 

 Heat, H = r4-q, see Davis, Tr. Am. Soc. Mech. Eng., 1908.
