The heats of combustion of pyridine and hippuric acid were determined by precision oxygen-bomb calorimetry, and these values, in kcal. mole/sup -1/, are reported for the standard heat of formation, ..delta..Hf/sup 0//sub 298.15/, from graphite, and gaseous hydrogen, oxygen and nitrogen: pyridine (liq.), 23.89; hippuric acid(c), -145.54. Recommendations are made for methods of determining the amount of reaction in combustion calorimetry. The suitability of hippuric acid as a reference substance for the combustion calorimetry of organic nitrogen compounds is discussed.
