[Cleavage methorl of Jleynert. Plates I, II, and V are the same hemisphere. Plates III and IV . 

 are from the opposite hemisphere of the same brain, that of a normal, male Filipino.] 



Plate I. 



Fig. 1. Association fibers. A, Part of the superior longitudinal fasciculus (occip- 

 ital-frontal band) ; B, cingulum; C, fibers from the frontal lobe to the 

 cingulum; D, cingulum. 

 2. Association fibers. A, Cingulum; B, inferior longitudinal fasciculus; C, 

 a band of fibers from the cingulum to the temporal pole; D, hippo- 

 campus; E, fibers from the mesial frontal convolutions to the cingulum. 



Plate II. 



Fig, I. Association fibers. A, Fibers of the corpus callosum; B, choroid plexus 

 under which lie the fornix and fimbria; C, part of the temporal pontile 

 path (Tiirk's bundle) ; D, fibers from C, E, and F to temporal and 

 occipital lobes; E, anterior commissure; F, genu of corpus callosum. 

 2. Association fibers. Corona radiata. A, Frontal pontile path (Arnold's 

 bundle) ; B, uncinate fasciculus; C, brain stem cut off; D, inferior 

 longitudinal fasciculus; E, part of optic striation [cccipito-mesencephalie 

 path (Flechsig's secondary optic radiation)]. 



Plate III. 



Fig. 1. Association fibers. A, Central sulcus of Rolando; B, Short fibrse propriae;
