containing a great number of nervous fibres which descend from 

 the hemispheres in the corona radiata and pass down to the 

 lower centres of the nervous system. The structure of both 

 parts of the striate body is very similar, both containing an ex- 

 traordinarily great amount of gray matter, interlaced with the 

 richest and most delicate net of capillary blood circulation, and 

 both appearing as a continuation and a specialised part of the 

 cortex. Fig. 2 shows the site of the caudate body in a sagittal 

 section, after Edinger ; Fig. 3 shows a vertical section of the 

 lenticular body, after Wernicke.

The anatomical structure of the striate body is sufficiently 

 similar to the cortical substance to indicate that they perform 

 an analogous function which may be the co-ordination of the 

 cortical activity so as to serve as a focusing centre.- The lentic- 

 ular body consists of three stripes which gave the name to the 

 organ. The third stripe, commonly called the shell or putamen 

 of the lenticular body, and also the caudate body, receives a 

 great number of fibres forming terminal stations which in many 

 respects are similar to those in the cortical substance of the
