In a recent article entitled "Influence of Copper and a Liver Fraction on Retention of Iron" (Arch. Int. Med.60:474 [Sept.] 1937), Barer and Fowler erroneously used the term liver rather than liver extract in referring to the results obtained by Cheney and Niemand (footnote 11) and by Powers and Murphy (footnote 12). In 1931 Powers and Murphy stated, "Liver extract is of no value in the treatment of these types of chronic secondary anemia" (The Treatment of Secondary Anemia, J. A. M. A.96:504 [Feb. 14] 1931). Murphy, however, in a subsequent article stated that in secondary anemia "treatment by means of intramuscular injections of solution of liver extract (Lederle) together with adequate doses of iron by mouth is the most effective" (Treatment of Secondary Anemia, with Special Reference to the Use of Liver Extract Intramuscularly, Arch. Int. Med. 51:656 [May] 1933).
