Fig. 4 Showing semi-diagrammatically the increase in size and the morpho- 
logical changes in the typical ganglion cells in the lamina ganglionaris of the 
cerebral cortex of the albino rat. The Roman number by each cell figure indicates 
the brain-weight group from which the typical ganglion cell was selected and 
the drawing made. All cell figures have been uniformly magnified to 950 diame- 
ters, according to the uncorrected measurements.
