To the Editor: —In the April issue of theArchives of Surgery( 30 :685, 1935) there is an article entitled "Experimental Pulmonary Embolism Associated with Venoclysis" by Mervin J. Rumold, of Kansas City, which seems to discredit the use of continuous intravenous injections. For several years I have been advocating and using continuous intravenous injections, particularly in connection with surgical procedures, and I have written several articles on the subject. The experiments of Dr. Rumold appear to have been carefully performed, but in my experience his conclusions do not seem applicable to clinical work for the following reasons: 1. The vein used by Dr. Rumold in all of his experiments (listed in the six tables) was the external jugular vein in a dog, except in 2 experiments in which the saphenous vein was used. In a dog the external jugular vein is large and practically supplants the internal jugular vein,
