On the basis of the data that have been presented it is possible to draw the 
following conclusions concerning growth compensation as it is indicated in the two 
age groups considered here: 
(1) Growth compensation occurs in both the group with a unimodal distribution 
of calculated lengths at the end of the first year of life and the group with a bimodal 
distribution of these lengths (negative correlation of Li and ALO. 
(2) Growth compensation is more intense in the group with the greater disper- 
sion of the calculated lengths at the end of the first year of life (higher negative 
correlation between L x and ALi in the III group). The tendency toward compen- 
sation can lead to a bimodal distribution of the growth increments for the second
