the convexities of which rest in the occipital fossae. This surface 

 of the middle lobe (' inferior vermiform process,' Anthropotomy) 

 is transversely folded or ' ringed.' The broader and more promi- 

 nent folds form the * pyramid,' ib. P ; the succeeding narrower 

 folds, the * uvule,' ib. n. The extremity of the vermiform process 

 which projects into and closes the fourth ventricle, inferiorly, is 

 the ' nodule.' On the inferior surface of the ' hemispheres ' An- 

 thropotomists define, with Reil, 1 'biventral,' fig. 63, h, * slender,' ib. 

 Cj, and ' post-inferior ' lobes, d. The smaller group of folds is the 

 'amygdala,' ib. a ; the still smaller group,/, is the 'flocculus.' 

 The anterior surface of the cerebellum, seen in connection with

the macromyelon, as in fig. 64, shows the ' semilunar fissure,' h, 

 penetrated by the formative and commissural columns, i : the rela- 

 tive position of the ' flocculus,' n 9 is here best shown ; the macro- 

 myelon passes into myelon at m. On the upper surface of the 

 cerebellum, fig. 65, its most prominent part is that of the middle 

 lobe, called s superior vermiform process,' v : the hemispheres are 

 almost flat: they are here subdivided into the ' square lobe,' ib. a, 

 and the ' post-superior lobe,' P. The lateral lobes exceed the
