52 A BIOMETRIC STUDY OF BASAL METABOLISM IN MAN. 



Our boys are slightly shorter and our girls a little longer than 

 Dr. Taylor's series, but the differences cannot be asserted to be 

 significant. All our variabilities, both absolute and relative, as 

 shown by the differences between standard deviations and coefficients 

 of variation in table 7, are less than the British series, indicating 

 that our measurements were made upon a group of infants somewhat 

 more uniform. Our male infants are slightly less variable and our 

 female infants somewhat more variable than Dr. Taylor's series. 



TABLE 7. Comparison of length of Nutrition Laboratory babies with other series. 



The correlations between stature (length) and weight in our infants 

 are as follows: 



For males N=5l, 



For females 7V=43, 



For both sexes A 7 =94, 



r sip = 0.770 0.038 

 r sw = 0.864 0.026 

 r aw = 0.821 0.023 



For comparison with those we have the constants based on 1000 

 male and 1000 female full-term new-born infants from the Lambeth 

 Lying-in Hospital by Pearson 34 . The results are : 



For males #=1000, 



For females #=1000, 



r Tn , = 0.644 0.012 

 r fw = 0.622 0.013 



Reducing the Anthropometric Committee's 35 data, which as noted 

 by Pearson are somewhat heterogeneous in origin, we find: 



For males #=451, 



For females #=466, 



r, = 0.665 0.018 

 r sw = 0.539 0.022 



The correlations between length and weight in Dr. Rood Taylor's 

 series are: 



For males ....................... r fn> = 0.668 0.034 



For females 



= 0.749 0.027 



For both males and females our correlations are higher than those 

 found by others. The differences are : 



Pearson'* series. 



For males, +0.1260.040 

 For females, +0.242 0.029
