In the report "Simple method for measuring heart vector of isolated animal hearts [Science 133, 1831 (9 June 1961)], by C. V. Nelson, the data for the rabbit heart experiments are given incorrectly in the first sentence of the last paragraph on page 1831. This sentence should have read: "In four rabbit heart experiments in the larger sphere, the average peak vectors were 235 µa-cm for QRS and 100 µa-cm for T."
