214: REPORT—1899. 
The velocity of transit for the P.T.’s is not given, because small errors 
in the time observations lead to marked discrepancies in the final results. 
A point of interest in the seismograms is that whilst at Shide and 
Kew the range of motion was 3 and ‘8 mm., at Toronto it was only °5, 
and at Victoria, the nearest station to the origin (71°), the movement 
was barely visible, and so indefinite that certain determinations of time 
are impossible. This latter place would be reached along a path entirely 
beneath the Pacific, Toronto by a path crossing Behring Straits, and 
Shide by a land path across Asia and Europe. 
Observations of this nature suggest that oceanic waters exert a damp- 
ing effect upon the earth waves traversing their beds.

The L.W. records for Toronto and Victoria, followed 13 and 27 minutes 
later by records at Batavia and Shide, suggest an origin in the Mid-South 
Pacific. :
