Fig. 3. Growth in weight of the foetal sheep, measured as cube
root of weight.
Figs. 4—8. Growth in weight of foetal rat, mouse, rabbit, cat and
human as in Fig. 3.
Fig. 9. The equations of the lines W1/3 against foetal age for eight
species with weights known at ages other than full term. Also the
generalised equation and its graphical representation.
Fig. 10. Przibram’s Data for many species graphed with t0 for each
brought to a common origin independently of its absolute value in
each case.
Note the Roedeer and the Bear which are close to the primate
line are cases of delayed implantation with tg apparently greater than
reality. On correction these points mowe to the left and come in the
mammalian class.
Fig. 11. The cube root growth lines for numerous Catacean species.
