hryonal connective tissue. The blood capillaries are particularly 

 numerous near the ependyma. 



If one examines now the ventricular surface, the corpus 

 striatum (fig. 19, c.s.) appears at the posterior point of attach- 

 ment of the lateral plexus as a single ridge in the floor of the 

 lateral ventricle. As it is followed anteriorly, this ridge is soon 

 divided by a groove into two portions. The lateral portion is
