EXPLANATION OF PLATE V. 
Figures approximately natural size. 
Figure 1. Diagram showing the relation of the meridians to the 
longer polar line. The approximate magnitudes of the angles a, 
fr, c and d, lettered clockwise, are 86°, 88°, 80°, and 106° respectively. 
Figure 2. The same as figure 1 about the shorter polar line. Angles 
a', c' and d', lettered counter-clockwise, equal 86°, 90°, 78%° 
and 106° respectively. 
Note that angle a, fig. 1, and angle a', fig. 2, are on opposite 
ends of the same “quarter”; angle & is opposite i>', etc. Their 
values in each case are nearly the same. 
Figure 3. Polar view of the specimen showing the meridians joining 
the longer polar line. The cleft follows the upper left hand 
meridian rather closely, then the polar line, and down the lower 
left hand meridian. It follows the last two lines and the planes 
extending in from them precisely. 
Figure 4. The opposite polar view. The cleft follows the upper right 
hand meridian, the polar line, and the lower left hand meridian. 
Fragments of the “epicarp” may be seen on both 3 and 4.
