known. They are derived from the application of the formula 

 given in table 22. In table 24 the constant term (66.473) and the 

 corrective term for body-weight (13.752u?) are combined, while in 

 table 25 the corrective term for stature (5.003s) and the corrective 

 term for age (-6.755a) are combined. 



The tables are from Harris and Benedict, Carnegie Institution of 

 Washington, publication 279, 1919, pp. 253-259. 



EXAMPLE. 



A man 27 years old, 172 centimeters in stature, 77.2 kilograms in weight. From table 

 24, 77 on side argument and 0.2 on top argument, we find 1128, and from table 25, 27 in 

 top argument and 172 in side argument, we find 678 calories; 1128 + 678 = 1806 calories ia 

 the predicted heat. 



TABLES 26 and 27. Standard multiple-prediction tables for normal 

 basal heat-production of women. 



These two tables together are used for predicting the most probable 

 basal heat-production per 24 hours of a normal adult female when the 

 weight in kilograms, the stature in centimeters, and the age in years 

 are known. They are derived from the application of the formula 

 given in table 23. In table 26 the constant term (655.096) and the 

 corrective term for weight (9.563w) are combined. In table 27 the 

 corrective term for stature (1.850s) and the corrective term for age 

 ( 4.676a) are combined. The tables are from Harris and Benedict, 

 Carnegie Institution of Washington, publication 279, 1919, pp. 

 260-266. 



EXAMPLE. 



A woman 66 years old, 162 centimeters in stature, 62.3 kilograms in weight From 

 table 26, 62 on side argument and 0.3 on top argument, we find 1,251 calories, and from 

 table 27, 66 in top argument and 162 in side argument, we find 9; 12519 = 1,242 cal- 

 ories is the predicted basal heat-production per 24 hours. 



TABLE 28. Calories per square meter of body-surface (height-weight 

 formula) per hour, Aub and Du Bois standards. 



The table gives the heat-production per hour on the basis of body- 

 surface as estimated from height and weight without clothing (see 

 table 18, p. 108). The standards are from Aub and Du Bois, Archives 

 of Internal Medicine, 19, 1917, p. 831. It should be stated that the 

 authors considered the values somewhat tentative and point out that 

 the figures for females are calculated as 7 per cent below the average 

 for males.

 females (Dreyer).

The formula for males is C= rTTTyiK x A - 1333 ' w ^ ere ^ ec l ua l s total 

 calories per 24 hours, W equals body-weight in grams, and A equals 

 age in years. It is from G. Dreyer, Lancet, 1920, Part 2, p. 290.
