testing significance of differences between the 

 growth parameters, the analysis of variance failed 

 to demonstrate an effect of either cohort or sex on 

 Loo, K, or to (all 5 values insignificant with P>0.05). 

 We concluded that there were no significant 



effects of either cohort or se.x on the number of 

 age-groups or growth parameters, and that 

 females tended to be statistically larger at suc- 

 cessive ages even though the magnitude of the 

 differences was not significant.

 growth curves (heavy lines) by sex for the 

 1959-65 cohorts. Observed mean lengths for 

 age-groups, represented by circles con- 

 nected with light lines, were used in fitting 

 the growth curves.
