Abstract: | One of the series of "Yale natural radiocarbon measurements, II" [Science 122, 954 (1955)], by Richard S. Preston, Elaine Person, and E. S. Deevey, was incorrectly reported through a technical error. The date for sample Y-293A (South Haven, Mich.: peat) was 10,790 +/- 200 yr, not 9500 + 250 yr as reported on page 958. |
