the end of the wider part, or caecum proper. The large intestines 

 are about 1 foot 10 inches in length. The colon, moderately dis- 

 tended, is 1 inch 2 lines in diameter at its commencement, and 

 gradually decreases in width. Beyond the first enlargements it is 

 not sacculated, but is slightly puckered on a longitudinal band, 

 which may be traced a few inches from the beginning of the gut, 

 where two or three pouch-like protrusions appear on inflation. 

 The ileo-colic aperture is slit-shaped, bounded by two low ridges, 

 that next the caecum being most produced. 1 



This type of cascum is repeated in Stenops jav aniens with a longer 

 and narrower ' vermiform ' termination : 2 in Stenops tardigradus

this part is shorter: 3 in Tarsius? Perodicticus, 5 Otolicnus? and 

 the Galagos, 7 it is wanting, and a moderately long and wide 

 caecum terminates obtusely, without 

 contracting : in Galago calabariensis 

 it is comparatively short : 8 in Galago 

 moholi, with a more efficient form of 

 molars for mastication, the caecum 

 is more than twice the length in pro- 

 portion to its calibre, and it is puck- 

 ered by a mesenteriole into five or 

 six short folds, fig. 327. The cardiac 

 part of the stomach is large in all 

 Lemurines, fig. 328, a : but the py- 

 loric part rarely protrudes to the right of the pylorus, below the 

 beginning of the gut. The duodenum is rather shorter in true
