The rabbit's duodenum was macerated in a mixture of nitric acid, glycerine and water. After the mucous membrane had been removed the structure represented by Fig. 9 was found. The course of the common bile-duct through the intestinal wall is parallel to that of the fibres of the inner circular muscular coat. This is just the reverse of what is found in the dog. At the first glance, one can see that the greater part of the duodenal portion of the common bile-duct is covered with muscle fibres of the inner circular muscular coat. Fig. 9. Macerated duodenal portion of the common bile- duct of rabbit. The mucous membrane, muscularis mucosae, and submucosa of the intestine have been removed. X ^? Some of these fibres of the inner circular muscular coat run up on the common bile-duct. A, continue for some distance and ter- minate abruptly near the orifice of the duct, R. Other fibres of the inner circular muscular coat run up on the duct, continue forward a short distance, but finally bend, some to one side, others to the oppo- site side, C, and runing down over the side of the duct, become.
