Note on the Earthquake of the 7th July, 1868. By 
R. J. Lechmere Guppy, F.L.S. & G.S., &c. 
On the 7th July, at 5h. 1m. a.m., a smart shock of earth- 
quake occurred in Port-of-Spain and its neighborhood. The 
duration of the shock was a few seconds only, and it was 
accompanied by a rumbling noise which preceded it by a 
perceptible, though very small, portion of time, and was 
quite distinct from the rattling produced by the earthquake 
in the materials of a house, furniture, &c. The direction 
of the earth-wave seemed to be, so far as I could ascertain, 
from NW. to SE. A minor shock occurred at 5h. 25m. a.m. 
Tuesday, 1 \th August, 1868.
