In the announcement of acceptance of Mead's Powdered Brewer's Yeast by the Council on Pharmacy and Chemistry (The Journal, May 2, p. 1477) it was erroneously stated that this product assays approximately 1 vitamin B2 (G unit) per gram. It should have read 10 instead of 1.
It was also erroneously stated that the unit of vitamin B1 used for that amount of substance which, added to the diet of rats showing symptoms induced by deficiency of B1 (F) would give an average weekly gain in weight of 3 Gm. for eight weeks. This should have read 11 to 14 Gm. instead of 3 Gm.
Another error was that the product offers not less than 0.98 unit of vitamin B2 (G) per gram. This should have read 10 units instead of 0.98 unit.
