he shocks which destroyed Oran at about 3} P. M., J uly 6, 
are stated to have been felt at Jujuy and Salta, at from 6 to 8 
minutes before 4, and at Tucuman (approx. lat. 26° 50’, long. 
46 15™) at about 4 35’ to 46 40™ But it must be remembered 
that in all these places most of the people are unaceustomed to 
any exact determination of time, and that even the few who carry 
it watches have no correct standard of local time. The 
and which are now provided with the correct Cordoba and 
Buenos Aires time, are beginning to remedy the deficiency, but 
this is comparatively a slow process. Therefore it 1s unsafe to 
found any careful estimate of the Mes the wave from 
been felt in Rioja, San Juan and Mendoza, along the eastern 
Stope of the Andes; but the data relative to the precise time 
of the shocks are so vague, that I do not venture to draw any 
inferences as to the rapidity with which the wave traveled. In 
Valparaiso there were eleven distinct shocks, so severe as to 
break all the telegraph wires between that city and Santiago.
