Zur Anatomie der primären Peritoneumfalten des Cäcalapparatcs etc. 93 



„Diese Vah-ula ileo-oolica bestimmt die obere Grenze des 

 Cöcum. Die Höhlung dieses Darmabschnitts stimmt mit 

 der des Colon überein, von dem er in keiner Weise 

 getrennt ist. Distalwärts verjüngt sich das Cöcum nur wenig 

 und geht dami direkt in den ProC. vermiformis über, der nicht 

 seitwärts, sondern genau in der Mitte des distalen ßlinddarm- 

 endes eingepflanzt ist." Das gleiche betont auch Owen^)

 reappears; it is terminal, and in some species sbort." 



2) Flower, W. H., 1. c., S. 394: „In the specimen No. 72.5 Ed in the Museum, 

 from the same individual as the stomach above- described, the appendix is 

 some what longer and coiled upon itself. Though it commences very abruply, 

 there is an important difference in its Situation from the forms previoußly 

 described, for it Springs from the extremity of a short conical caecum. The 

 whole retains more nearly the primitive form, the true apex not being drawn 

 up to the neighbourhood of the ileo-caecal valve. It thus represents a stiU 

 earlier condition of the human embryonic caecum than the orang, but hardly 

 justifies Vroük's expression that the , vermiform appendix is very small and 

 almost rudimental in the gibbons'. One specimen however, which I have 

 examined of the ,silvery gibbon' has the appendix only an inch and a half long 

 and proportionately thick. In the animal examined by Daubenton it was 

 five inches long and two and a half lines in diameter. It seems, therefore, 

 that there are considerable differences in the structure of this part."
