PLATE 30 
EXPLANATION OF FIGURES 
109 Cells of the nucleus posterior thalami. Toluidin blue method. 575. 
110-113 Neurones of the nucleus posterior thalami. Golgi method. 93. 
From sagittal sections. As will be noted, the cells of this nucleus are very large. 
They appear larger in sagittal than in transverse sections, both in toluidin blue 
and Golgi material. 
114 Transection at approximately the same level as that shown in fig. 106. 
Weigert method. X 17.
