would be really satisfactory, and least of all to him. We use, as before, Dr Lee's 
inter-racial formula from the footnote, p. 247 of her memoir, i.e. 
G = 321-16 + -OOO.STOZ xBxH. 
The following results were obtained by iising the three prediction formulae.

Again both the correlation formulae come out with a less mean error than 
Dr Beddoe's ^3, the diametral formula being sensibly the best. For the means 
Dr Beddoe is slightly better. We may stay here to note that G. F. is really a mean 
individual and not an inter-racial formula. The inter-racial formula for these ten 
races gives us : 
C = 316-2 + -01852 Ux S x Q. 
This formula should be used in preference to G. F. for race means. It does not 
however give any very substantial advantage in the present case. 
We have for the inter-racial arc formula (/. A. F.)
