PLATE B. 



Fig. I. Pyramidal cortical cell and portion of a capillary Tcssel from fron- 

 tal lobe (Plate E, Fig. i, No. 4. The cell is but slighly altered. The vessel is 

 in the first stage of degeneration. The granules are multiplying and escaping 

 into the perivascular space. 



Fig. 2. A group of cells from the layer of deep pyramids in Broca's region. 

 An enormous cyst-like mass of pigmentary degeneration in one of the motor 

 cells. 



Other cases of degenerated cells from Broca's region. 

 A case of varicose alteration of the apical process. 

 Similar instance from temporal lobe (No. i). 

 ' Incipient degeneration in a cell of the temporal lobe. 

 Striking instance of pigmentary degeneration in Broca's region. 

 Incipient degeneration of cell from frontal lobe. 

 So-called scavenger cells from temporal lobe. The tangential 

 fibres form the upper margin of the section. 

 Fig. 10. Deep pyramid of frontal lobe. 

 Fig. II. Superficial pyramid of the same region. 



Fig. 12. Three slightly altered large pyramids of Broca's region. The 

 sole indication of the lesion is an increase in the pigment. 



Fig. ij. Large Pyramids from Precentral convolution. (No. 2.) 



PLATE C. 



Fig. I. Part of a transection through the cephalic corpora quadrigemina 

 and pulvinar. 



Fig. 2. Part of a similar section through the roots of the third nerve. 



Figs. J, 4. Degenerating cells of the nidulus niger from the sections above 

 indicated. 



Fig J. Slightly altered cells of Purkinje from the cerebellar area shown 

 in Fig. 6. 



Fig. 6. Apparently normal cerebellar cortex. Compare with Fig. 4, 

 Plate E. 



PLATE D. 



Fig. I. Transection of left hemisphere through the thalamus and hippo- 



camp.
