1) For clarifying the accurate information about the normal anatomy of the gastric lymph nodes and lymphatics of the dog, twenty adult mongrel dogs were utilized, and the gastric lymph nodes and lymphatics were visualized with direct sky blue or india ink under as physiological condition as possible. 2) The lymph nodes found in the upper abdomen of the dog were classified into these fifteen groups: lymphonodi gastrici superiores, ln. suprapyloricus, lnn. subpylorici, hilus-lienis lymph node, lnn. pancreaticolienales, lnn. coeliaci sinistri, ln. coeliacus superioris, ln. coeliacus dexter, ln. retropyloricus, lnn. pancreaticoduodenales, porta-hepatis lymph node, lnn. colici dextri, lnn. colici medii, lnn. mesenterici and lnn. lumbales superiores. Of these, the superior gastric nodes, the suprapyloric node, the subpyloric nodes, the hilus-lienis node, the pancreaticolienal nodes, the left coeliac nodes, the superior coeliac node, the right coeliac node, the retropyloric node, the pancreaticoduodenal nodes, the right colic nodes and the superior lumbar nodes received lymph from the stomach. The suprapyloric node and the hilus-lienis node were rarely present, and the right colic nodes, though constantly present, received a little of the gastric lymph only infrequently. 3) The left coeliac nodes, the superior coeliac node, the right coeliac node, the retropyloric node and the pancreaticoduodenal nodes were considered as the terminal lymph nodes of the stomach. 4) The lymphatics of the stomach were classified into these five routs: the left gastric, the right gastric, the right gastroepiploic, the left gastroepiploic and the fundic rout. 5) The lymphatics of the cardiac portion followed the left gastric rout, and those of the fundus followed the left gastric and the fundic rout. The lymphatics of the lesser curvature side of the body and those of the same side of the pyloric portion followed the left gastric and the right gastric rout. The lymphatics of the greater curvature side of the body took the left gastroepiploic and the fundic rout, and those of the same side of the pyloric portion took the right gastroepiploic rout. 6) The terminal lymph nodes were common to the lymphatics of the right gastric rout and to those of the right gastroepiploic rout. These two groups of lymphatics terminated in the retropyloric node or in the right coeliac node, and, partially, often in the pancreaticoduodenal nodes and rarely in the right colic nodes. They showed resemblance in the course near the terminal lymph nodes. 7) It was emphasized that the retropyloric node was the main terminal lymphatic station of the right gastric and the right gastroepiploic rout, and, in relation to the fact above, the descriptions formerly reported about the right coeliac node were criticized. 8) The efferent lymphatics from the terminal lymph nodes of the stomach and from the lymph nodes which drained the viscera supplied by the superior mesenteric artery (the right colic, the middle colic and the mesenteric nodes) joined together complicatedly. These efferent lymphatics formed a single trunk, the truncus intestinalis, beside the root of the superior mesenteric artery in thirty three per cent, and in sixty seven per cent formed a network, the rete intestinale, around the root of the artery.
