Summary The times of P in six Japanese and five “European” earthquakes, selected because good determinations of epicentres are possible from stations within 30°, are studied. Revised tables for earthquakes in Europe and Japan are constructed. Evidence concerning differences of the times at distances over 30° is some what conflicting; if there are any they do not exceed 2 8 , but a difference of the order of I part in 300 between the velocities under the eastern and western halves of Eurasia is possible.
