Puncture the tendon on the right side and note the collapse of the right lung as soon as air enters the pleural cavity. 17. With the liver still pulled down, note the short hepatic veins proceeding from the liver to join the vena cava inferior just below the diaphragm. Cut through the hepatic veins as close to the liver as possible and remove the liver. 18. Out open one of the hepatic veins and trace it in this way back into the substance of a liver lobe. Observe on its inner surface the opening of numerous smaller veins; cut through the lobe near its base, and try to distinguish the portal veins from the hepatic by the small bile duct and small thick-walled artery running alongside the former. 19. Out away the mesentery from the alimentary canal, and trace out the latter along its whole length, observing more fully the features men- tioned in § 8, and noting in addition one or more white patches (Peyer's patches) on the free sur- face of the ileum, due to clumps of lymph-follicles; also note the connection of the csecum with the small and large intestine, the thin walls of the csecum and the thicker spotted walls of its appendix. !N^ote in the dog, the wider oesophagus entering into the stomach nearer the cardiac end than is the case with the rabbit; note also the shorter
