To the Editor:
—In The Journal, April 1, Bernheim makes out a rather sad case for the average American diet with respect to calcium. Without trying to detract from proved clinical uses of calcium, I would say that conclusions based on the realms of probability are questionable. Thus, specifically quoting Sherman, she states that "probably a larger proportion of the ordinary dietaries, both of adults and of children, can be improved by enrichment in calcium than in any other one chemical element" and, further, "he believes that a number of weaknesses and increased susceptibilities to infection may be the results of calcium deficiency," although in his original article Sherman says "probably plays a part in a numberof weaknesses and increased susceptibilities to infection without being exclusively responsible for any one of them."The size of the rôle calcium plays in the difficulty appraised human equations of "passable" and "buoyant" health
