bodies), and the pulvinar. In the sheep the lateral geniculate 

 body is not clearly separate from the pulvinar, forming the 

 most ventral part of the eminence which includes both of these 

 structures. The medial geniculate body (Fig. 12) is con- 

 nected with the inferior colliculus by a clearly defined ridge, 

 the peduncle of the inferior colliculus (brachium quadrigeminum 

 inferius). The connection of the lateral lemniscus with the 

 inferior colliculus and medial geniculate body has already been 

 mentioned (Sections 81, 82, and 106). The optic tract is 

 similarly related to the superior colliculus, lateral geniculate 

 body, and pulvinar (Section 136) ; but the further dissection of 

 this region to expose these connections must be deferred until 

 after the removal of the cerebral hemisphere.

 and locate the lobes and the fissures and gyri given in the follow-

 these parts: Cunningham ('15), Figs. 581, 582, pp. 654, 655,
