Chart 3. Showing a comparison of sizes of the cell bodies and of the nuclei 
of the ganglion cells in the lamina ganglionaris and of the pyramids in the lamina 
pyramidalis in brains of the Norway and the Albino, according to the actual brain 
weights. The data are taken from tables 3 and 7. The chart has been divided 
and the values 22-26 on the ordinate repeated to prevent confusion among graphs 
for the cell bodies of the pyramids, PC and PC’, and the graphs for the nuclei 
of the ganglion cells, GN and GN’. In the upper chart: Graph GC’, cell body 
of the ganglion cells in the Norway. Graph ‘GC, cell body of the ganglion cells 
in the Albino. Graph GN’, nucleus of the ganglion cells in the Norway. Graph 
GN, nucleus of the ganglion cells in the Albino. In the lower chart: Graph 
PC’, cell body of the pyramids in the Norway. Graph PC, cell body of the 
pyramids in the Albino. Graph PN’, nucleus of the pyramids in the Norway. 
Graph PN, nucleus of the pyramids in the Albino.
