In the article "Radio telemetering from within the body" by R. Stuart Mackay [Science 134, 1196 (20 Oct. 1961)] one line was omitted and another line was printed twice in the paragraph beginning just above the middle of column 1, page 1199. The first line of the paragraph is repeated in the fourth line. The first two sentences should have read: "The permissible radio-frequency deviation is limited to the bandwidth of the receiver if loss of signal is never to occur. Receivers can record higher-deviation signals by tracking them with a standard automatic frequency-control circuit, the frequency-discriminator signal then being the useful output (8)"(italicized words omitted).
