In the article by Steininger, Roberts and Brenner in The Journal, Dec. 30, 1939, page 2381, in the last item in table 1, which refers to the article by Clausen and McCoord, the statement that the "rate of absorption of vitamin A is slower than that for carotene" should have been just the opposite, that is, that the "rate of absorption of carotene is slower than that for vitamin A."

In view of Marian S. Kimble's paper published in the Journal of Laboratory and Clinical Medicine in July 1939, attention has been called to the following statement in Steininger, Roberts and Brenner's paper: "With the exception of the work of Clausen and his associates, these studies have all been done in foreign countries." The authors state that the foregoing quotation was correct at the time their paper was submitted to The Journal.
