In Reply.—I am pleased that Dr Beemer and his colleagues have so promptly plugged the molybdenum gap in my review articles. With hind-sight I see it was a serious omission but in writing the review I was conscious that it was turning out very much longer than the editor had requested.
May I take this opportunity of making a correction. The molecular weight of ceruloplasmin has been revised downwards and is thought to be close to 134,000 daltons, and one molecule binds six atoms of copper.1,2
