The same type of diagram may be used to show the relation 

 ship between the size at early and at later growth stages. Dia 

 gram 2 shows the distribution of the magnitudes of the correla 

 tions for sizes of the individuals at the ;th to the ;oth day (stage) 

 and the size at subsequent growth stages. 



From these lines it is clear that the correlations between size

 ception for every period which furnishes evident 



question. 



The coefficients are, however, positive in sign throughout, tl 

 ni-esting (though in some cases not proving) that throughout 

 its growth period the size of the plant bears some relation 

 when first measured. This result is in agreement wit.
