Summary
In the epiphysis as well as the hypendyma of the subcommissural organ ofCamelus dromedarius rosette formations were observed. They have probably been formed from the ependyma. Selective staining methods showed up granular mass in the rosettes of the subcommissural organ but not in those of the epiphysis. The function of these formations is discussed.
Zusammenfassung
Sowohl in der Epiphyse als im Hypendym des Subcommissuralorgans beiCamelus dromedarius wurden Rosettenbildungen festgestellt. Diese sind wahrscheinlich vom Ependym gebildet. Mittels selektiver Färbungen konnten körnige Massen in den Rosetten des Subkommissuralorgans, nicht aber in denen der Epiphyse nachgewiesen werden. Es wird über die Bedeutung dieser Rosetten diskutiert.
Résumé
Chez leCamelus dromedarius les formations de rosettes peuvent être observées dans l'épiphyse et dans l'hypendyme de l'organe sous-commissural; il est vraisemblable qu'elles sont formées de l'épendyme. Les formations de rosettes de l'organe sous-commissural contiennent une substance granulaire électivement colorable, mais nous ne les avons pas pu observer dans celles de l'épiphys. On discute la signification fonctionelle des formations de rosettes.
