ventricle. 1 On the other hand, the axons from the cells of the corpus albicans 

 (its mesial nucleus) bifurcate soon after leaving the cells, and while one set of 

 "branches pass by way of the bundle of Yicq d'Azyr to the anterior nucleus of 

 the thalamus, the other set go to the tegmentum, and are ultimately traceable 

 to the region of the trapezium in the pons Yarolii ; these form the pedunculo- 

 maxillary fasciculus of Ramon y Cajal, 2 or the tegmental bundle of v.Gudden. 

 From the lateral nucleus of the corpus albicans, other fibres, constituting the 

 so-called peduncle of the corpus albicans, pass to the tegmentum, to end 

 apparently in the central grey matter. 



The hippocampus also sends fibres by way of the fornix and stria medullaris 

 thalami to the nucleus habenulae, whence other fibres arise and pass to the 

 interpeduncular ganglion by way of Meynert's bundle (fasciculus retrofl exits). 3
