The right occipital lobe, besides being softened on its upper aspect, was discoloured 
and covered by a layer of extravasation, which likewise covered the right nates. The 
nates themselves were, however, uninjured, and of normal consistence.

Fig. 26 represents by shading the extent of softening on both hemispheres of the monkey in Experiment 
XXI. The transverse line on the left occipital lobe is the line of section, and the part marked by paralle lines 
is the part entirely removed.

by parallel lines was cut off. The shading indicates 
the extent of lesion of the surface. 
The posterior limb of the right angular gyrus was softened and discoloured yellow, 
owing to the contact with the cotton-wool soaked with perchloride of iron which had

The optic tracts and cranial nerves were intact. 
The upper part of the tentorium cerebelli on the left side was covered with pus, and
