 over the lateral face of the hemisphere the upper half of the area peri- 

 parastriata including its portion lining' the simina sulcus — the lower 

 third of that area remained normal — and the upper half of field 7. 

 Over the inner face of the hemisphere the entire field 18 of Brod-

 faces of the monkey's hemisphere where the occipital lobe and the entire striate 

 area including its portion sunk in the calcarine fissure (Fcalo) were removed. 

 Areas shaded with lines represent cut surface of the occipital lobe, and after the 

 removal of the betweenbrain. In this experiment the external geniculate body 

 degenerated completely on the same side, the opposite body remained normal. 



mann, the greater part of the dorsal half of field 19, and also the 

 posterior portion of the lower half of the same field were destroyed. 

 (Compare fig. 20.) The rest of the left hemisphere and the right 

 hemisphere, as well as the remaining parts of the brain, showed a 

 normal appearance.
