EXPLANATION OF FIGURES 2 AND 3. 



Fig. 2. 

 Drawing to show the deep abdominal lymphatics, the thoracic duct, and the subcutaneous duct in the case 

 described in the text. The inferior half of the aorta and the inferior vena cava are removed to show the plexus and 

 glands lying on the bodies of the vertebrae. The azygos vein is cut and drawn back to show the ending of the minia- 

 ture thoracic duct. The * shows the place at which the subcutaneous duct was divided early in the dissection. The 

 anterior end of the left kidney is cut off to show underlying lymphatics. The arrows are opposite the place where 

 definite valves were found in the subcutaneous ducts. A, most anterior of lymphatics of abdominal plexus; a. d. l., 

 anterior duplicating lymphatic; m. l. d., main lymph duct; p. d. l., posterior duplicating lymphatic; th. d., thoracic 

 duct, ending blindly anteriorly, where it was broken during dissection; v. saph. m., vena saphena magna. In the 

 lumbar region several cut ends are shown of vessels which passed ventral to aorta and vena cava; the continuations of 

 these vessels are shown in fig. 3. 



Fig. 3. 



Drawing to show the abdominal lymphatics lying ventral to aorta and vena cava inferior. Their connections 

 with the deeper lymphatics are shown as cut ends. The arrow indicates the beginning of the main lymphatic dud 

 a, same as fig. 2; a. l. v., ascending lumbar vein, running from the renal vein to join with the hemiazygos vein 

 (hemiaz. v.) to form the connecting vein (conn, v.), which crosses ventral to the aorta to join the azygos vein; L. hen. v., 

 left renal vein; l. ov. ves. and r. ov. ves., left and right ovarian vessels; ccsl. ax., celiac axis; sup. mes. a., superior mes- 

 enteric artery; inf. mes. a., inferior mesenteric artery; th. n., thoracic duct.
