Abstract
IN the last sentence of the second paragraph of my original, 40K was misread for 41K ; the definition should read : R is the ratio of 39K/41K. Similarly, at the end of par. 4, σ29 should read σ39, and in par. 5, line 17, σ40 should read σ39. An error in the numerical evaluation of the radiation age led to a figure exactly half that of the correct value. Therefore, in both par. 5, line 2, and in par. 7, line 6, 0.69 should read 1.38 × 109 years. Fortunately, these corrections do not affect either the principle of the calculation or, in general, the comparisons drawn in this letter.
