^{page 256 note 1} The normality of these curves has been tested by calculating the values of √β₁ and β₂−3. √β₁ is insignificant for all these distributions but β₂−3 is 2½ times its standard error for the air velocity group 20–49 feet per minute and four times its standard error when all the readings are taken together. Thus the distribution curves are not significantly skewed but for air velocities above 20 feet per minute the distributions are slightly leptokurtic.

^{page 256 note 2} For this distribution both √β₁ and β₂−3 are less than their standard errors.

^{page 260 note 1} This formula has been taken from the paper by Bedford, T. and Warner, C. G. (1933: The influence of radiant heat and air movement on the cooling of the kata-thermometer. J. Hygiene, 33, 330–48), but H_R has been substituted for H_RT, the emissivity E has been put equal to 0‐9, and the corresponding alterations made in the constant.CrossRefGoogle ScholarPubMed
