P.S. 28th. — The most violent earthquake felt occurred on the 

 night of the 20th. just before midnight. As usual, there were two 

 shocks ; noise with the first or preceding it, and the second most 

 sensible ; the former continuing four and the latter twelve seconds. 

 Standing erect, the direction from which the noise and wave came 

 was undoubtedly near W.S.Vv'.; and this position was assumed at the 

 earliest symptom, that these facts might be more easily appreciated. 

 Our seismometer gave no tidings.

1. "Experimental Researches in . Electricity." Twenty-fourth 

 Series. On the possible relation of Gravity to Electricity. By 

 Michael Faraday, Esq., D.C.L., F.R.S. 6cc. 



Under the full persuasion that all the forces of nature are mu- 

 tually dependent, and often, if not always, convertible more or less 

 into each other, the author endeavoured to connect gravity and 

 magnetic or electric action together by experimental results, and 

 though the conclusions were, when cleared from all error, of a nega- 

 tive nature, he still thinks that the principle followed and the ex- 

 periments themselves deserve to be recorded. Considering that some 

 condition of tlie results produced by gravity ought to present itself, 

 having a relation to the dual or antithetical character of the mag- 

 netic or electric forces, it seemed to the author that the approxi-
