204: REPORT—1899. 
At Kew the chief movements were as follows :— 
H. NM. 
20 34:9 semi-amp. 5mm. or 2'°75 
0 37 2°8 155 
0 378 32 175 
0 40°7 3 1'"-65 
It will be observed that the amplitude at Kew is smaller than the one 
from Shide. 
An inspection of the time records shows that the disturbance first 
reached Batavia and Madras. The heavy movement reached Ischia and 
Rocca di Papa 12m. or 13m. later, Shide and Kew 18m. later, and 
Toronto about 45m. later. With the assumption that the large waves 
travelled at a rate of about 2°5 kms. per second, these time intervals 
would lead us to look for the origin of this earthquake in the South 
Indian Ocean eastwards of Madagascar.

The L.W. records for Shide and Toronto would indicate an origin on 
the west side of the Atlantic, but this does not accord with the records 
from Potsdam and Nicolaiew.

The minuteness and irregularity of the earlier movements render it 
impossible for Shide, Kew, and other places to give an exact commence- 
ment. The large movement recorded in Toronto suggests an origin nearer 
to that place than to Europe.
