 Fig. 3. 

 Photograph of a dissection of the brain, from the lateral aspect. Occ. 

 lobe, occipital lobe. F. o. f. i.\ F. o. f. i.^ F. o. f. 1.=*, fasciculus occipito- 

 froutalis inferior, cut before it reaches the frontal lobe. Nuc. lent, nucleus 

 lentiformis. F. trans. o.S F. trans, o.", fasc. trans, occ, greater part removed 

 to show the fibers of the fasciculus occipito-frontalis inferior at this place 

 as it spreads over the posterior horn of the lateral ventricle. F. o. f. 1.-, shows 

 some of the fibers of the fasc. occip. front, inf. as they curve round the under 

 surface of the posterior part of the descending horn of the lateral ventricle 

 and the posterior horn itself, as they proceed to the under surface of the 

 occipital pole. Hipp., cut edge of hippocampus major. F. arc.S anterior 

 descending branch of fasc. arcuatus entering the white substance of the sup. 

 temp, convolution. F. arc.^ fasc. arcuatus (horizontal part). L. g. b., lat- 

 eral geniculate body. Cna., corona radiata, temporal part. Corona, corona 

 radiata to frontal lobe. Ant. c.\ ant. c.^, anterior commissure. Roof desc. 

 h., roof of descending horn of lat. ventricle. The roof of desc. horn is made 

 up of fibers of the thalamic radiation, the tapetum, stria semicircularis, and 

 tail of the caiidate nucleus. Ext. c, part of the ext. capsule left on the nuc. 

 lentiformis. 



Fig, 4. 

 Photograph of a rougli dissection of the full course of fasc. occip. frontalis 

 inf., F. o. f. i.\ and F. o. f. i.^ seen from the lateral aspect. The fasc. unci- 

 natus has been removed, and also the descending branches of the fasc. arcua- 

 tus (F. arc.) have been cut off and dissected away, and the transverse ver- 

 tical occipital associating bundle has been removed. Ext. cap., external 

 capsule. Opt. tr., optic tract. Ant. c.^ broken edge of anterior commissure 

 as it spreads out into the temporal lobe. C!orp. alb., corpus albicans. Cr., 

 crus cerebri. Cna., edge '^f the temporal part of corona radiata.
