3833. Vermiform Appendix, Caecum, and parts of Small 

 Intestine and Colon of Rabbit (Lejms cuniculus), with the 

 Peyerian and also some of the mesenteric glands in connexion with 

 them injected. 



The Anatomical Department., University Museum, Oxford. 



The ileum and colon lie side by side, the former describing a siphon-shaped 

 curve before ending in a dilatation, known as the " sacculus rotitndus" and 

 homologous with the aggregation of Peyerian follicles situated in man just 

 anteriorly to the ileo-csecal valve. The sacculus rotundus occupies the 

 centre of the preparation ; above and a little to the left of it another somewhat 

 similar aggregation of Peyerian follicles is seen just beyond the ileocolic valve. 

 The colon curves backwards externally to and concentrically with the ileum. 

 The caecum consists of two portions : one larger in calibre, thinner in walls, 

 and sacculated spirally ; the other, the homologue of the human " appendix 

 vermiformis," smaller in calibre, but with much thicker walls. Prepared by 

 Mr. llobertson. 



3834. Appendix Vermiformis of Rabbit (Lepus cuniculus), 

 with a small portion of the caecum and a larger portion of the small 

 intestine left in apposition with it.
