In the article by Drs. Martin and Morton on "Clinical Studies with the Electrogastrograph" printed in the September issue, page 382, the following changes should be made: Dr. Morton's initials are H. S. On page 384 the sixth sentence of the second paragraph should read: "The electrodes are reproducible to within 1 or 2 mv., but once made they must be treated with care, since they are photosensitive." In the second paragraph on page 392 the position of the last two sentences should be reversed. Footnote 35 should read "Gray, M.; Hokin, L. E., and Rehm, W. S.: Am. J. Physiol.155:440, 1948."
