1 here are few observations of greater importance, in refer- 

 ence to the theory of earthquakes, than the determination of 

 the exact time when they are felt at sea. The place where 

 they have their origin, — the velocity with which they are pro- 

 pagated, — and their probable depth beneath the surface, may
