Although the electrical method as here carried out is the moreprecise because of the avoidance of large cooling corrections,nevertheless the ultimate accuracy with which the results can beexpressed in terms of the calorie is limited by the accuracy withwhich the ratio of the joule to the calorie is known (at present.
