To the Editor: We are grateful to Dr. de Bergh for his stimulating criticism of the scientific exhibit on "The Stasis Syndrome." Careful understanding and thoughtful study of the exhibit will answer the questions which have arisen in Dr. de Bergh's letter. We are aware of the fact that the deep veins normally return 80% to 90% of venous blood. This is concisely stated in the figure on the bottom of page 280, point No. 3, "Deep veins normally return 80 to 90% of venous blood."

In addition, the charts on this same page, and the figures adapted from Linton, clearly demonstrate the development of localized congestive failure when the valves of the perforating and deep veins are incompetent. The pressure relationship in the figures indicate profound changes in hydrostatic pressure in limbs when incompetency of the perforating and deep veins exists.
