At the meeting of the National Academy of Sciences and the American Physical Society, held in Washington, D. C., April 24th and April 27th, respectively, we made our first public presentation of the evidence for the existence of a theretofore unsuspected cosmic-ray effect which we called “The Longitude Effect.” This evidence consisted in the projection and discussion of Figs. 1 and 2, again reproduced herewith. In the first of these were collected the readings of our self-recording, vibration-free, Neher electroscope, when taken inside its 10 cm lead shield, on four separate passages made in the interval November 1932 to January 1934, between Los Angeles and the western coast of South America.
