PLATE 2 
EXPLANATION OF FIGURES 
Figure 7 is diagrammatic to the extent that it was drawn from two different 
sections in the series, one cell from one section and the other from one three 
sections farther along in the series. Several sections show the two cells side by 
side. The plane of the section lies parallel with the intracellular axones and with 
the curve around the nuclei. Here also, as in figures 2 to 5, plate 1, the axone 
fibrils are in contact with the nuclei, forming indentations. One cell shows 
marked undulations in the axone near its exit from the cell body and shows also 
the neurofibrillae in a position parallel with the undulating surface. The neuro- 
fibrillae could not be traced far into the cytoplasm. The clear reticulations show 
continuity with spaces radiating from the path of the intracellular axone. 
Figure 8 is a photograph of a section from another specimen. In this the 
curve of the intracellular axone is in the opposite direction from that in fig- 
ure 7. The plane of section lies within one axone for a slightly greater distance 
than it does in the other, in the one being more nearly through the center of the 
nucleus. 
Both figures are from A. O. B. preparations. Magnifications: figure 7, X 
562; figure 8, < 750.
