76. April 10. 



The commencement and end of the record from Cordova is not clear, otherwise it is well defined, 

 possible that the origin was off the West Coast of South America, in the same region as No. 72. 



77. April 10. 



It is 



From the times of the arrival of M at the first three stations an origin is arrived at on the S.W. 

 continuation of the New Zealand axis, or approximately at 140 E. Long, and 55 S. Lat. The times of 

 arrival of the larger waves at Shide and Bidston, roughly 160 distent from the origin, indicate they 

 refer to the disturbance recorded by the " Discovery." The superficial area disturbed by this earthquake 

 was apparently a band 50 in width running from its origin in a N.W. direction to its antipodes. 

 It does not appear to have reached the continent of North and South America to the N.E. and E., Java, 

 Manila, or Japan to the .N., India to the N.N.W., or the Cape of Good Hope to the W.N.W. 



78. April 12. 



Assuming that these records refer to the same earthquake, the inference is that the area disturbed is 

 similar to that given for No. 77. 



79. April 15. 



Origin local.
