The footnote on p. 237, vol. 5, February 1950 issue, indicated that product II is at present being manufactured with a calcium:phosphorus ratio of 1.0 as a result of the addition of phosphoric acid commonly used in milk processing. This is in error. Since October 1948, product II has been manufactured with a standardized calcium: phosphorus ratio of 1.5 and no phosphoric acid is used. The research reported in this paper, however, was conducted on the product of prior manufacture which contained a calcium:phosphorus ratio of 1.0.
