Summary Readings have been made of records of three European earthquakes, with the object of testing the behaviour of S between 10° and 20°. In the earthquake of 1950 September 5, a linear formula fitted up to about 9°, but there appeared to be a jump of about 4 s at that distance. There were too few observations in the range in question on 1951 May 15 to give useful information. The Dalmatian earthquake of 1962 January 7, however, had 16 S readings between 10° and 20°. They showed no sign of a jump and were substantially earlier than the J. B. Table of 1940. It appears that a linear function of distance may fit the times of S in Europe up to 20°.
