GROWTH OF THE FETAL CENTRAL NERVOUS SYSTEM 435 
Growth of the cerebellum 
The growth of the cerebellum is portrayed by the graphs in 
figures 10 to 13, inclusive, and by the outline sketches in figure

Fig.10 Field graph and curve of the growth of the cerebellum in weight and 
volume in fetal life. Abscissa: total body length in em. Ordinate: cerebellum 
weight and volume in grams (cc.). Individual cases indicated by solid dots 
(for weight) and by circles (for volume). Curve drawn to the formula: Y = 
0.01 [(0.095X )4:9 + 20.0]. (Data from tables 17 and 18.)
