3 p.m. Still continues sitting as before. When disturbed moves very unwillingly and 
apparently with great caution, as if its sight were impaired, occasionally knocking its 
head against obstacles. Drank some water, but would not eat. 
9 p.m. The animal remains as when last seen. Has taken no food. 
January 24 th . — 11 a.m. Found lying prostrate in the cage. Killed with chloroform. 
Post mortem Examination . — The exposed surface of the occipital lobes on their supe- 
rior and lateral aspect was soft and pulpy and suppurating. The extent is marked by 
the shading in figures 29, 30, 31. The softening extended deeply into the interior, but 
did not affect the under or inner aspect of the lobes. 
The angular gyrus on both sides was of normal consistence, but the grey matter had 
a yellowish tint in the posterior half. 
There was no effusion into the lateral ventricles. 
The rest of the brain was quite normal. 
Fig. 29 represents by the shading the extent of destruction of the grey matter of the occipital lobes in 
Exp. XXTT .
