Discussion of table 4. The arrangement of the subjects in 

 phyletic groups, and their arrangement within these groups

 that which might be expected to obtain at a given position 

 in the ontogenetic and phylogenetic scales. The highest per- 

 centage for each subject is marked by an m in the table in order
