ON THE FUNCTIONS OF THE CEREBRUM 337 



FIG. 7. 



FK;. 7 (Marie, 1906) Horizontal section of the left hemisphere of Ber. . 

 The third frontal convolution is almost entirely destroyed by a softening. This 

 patient showed neither any sign of Aphasia nor any anarthric trouble. 



Fio. 8 (Marie, 1906). Horizontal section of the left hemisphere of Per. . . . 



The softening nu-t with here is the type of deep softening of form B. It is 

 indicated by the black line which, from R to R', occupies the external capsule and 

 the base of the white substance of the convolutions of the insula. At K the 

 line of softening bifurcates and extends forward and inward towards the inviuul 

 capsule ; posteriorly the softening crosses the temporo- parietal isthmus, and passes 

 into the white substance of the temporo-occipital lobe R", where it occupies the 

 neighbourhood of the external wall of the occinital horn of the lateral ventricle, and 

 follows its contour closely ; it leaves this wall quite at the back of it and ends in 

 tin- wliitf Mil istance of the occipital lobe. 



Tlii- ]'.iti'Mit was one of the finest cases of the Aphasia of Broca that I have had 

 tin- o[i]>oitiniity of observing. Here the Aphasia of Broca 'had been set up, owing 

 to thf Ifsion H R' which had caused Anurthria, and to the lesion R' R" which had 

 caused Aphasia.
