of the Earthquake Waves on the Coasts of the Pacific. 185 
towns of Chancay, Guara, and the valleys Della Barranca, 
Sape, and Patevilca underwent the same fate as the city of 
Lima.” 
Five years afterwards, in 1751, on the 26th of May, the 
city of Conception, called by the Indians Penco, on the coast 
of Chile, was totally destroyed by an inundation of the sea; 
in consequence of which the inhabitants removed to some di- 
stance from it, and rebuilt their city on the spot where it now 
stands. 
In Molina’s account of Chile, speaking of this event, he 
mentions that the city was agazm inundated, alluding to a si- 
milar catastrophe which had befallen it some years before, in 
1730: to which Ulloa has more particularly alluded. He 
says, on that occasion (in 1730) * the sea at first retired a 
considerable way; but soon it rose so greatly that, passing its 
ordinary bounds, it inundated the city (Penco) and the country 
about it, obliging all the inhabitants to seek safety on the neigh- 
bouring hills.” 
The earthquake wave which overwhelmed Conception in 
1751, was equally felt at the island of Juan Fernandez. I have 
a manuscript report of the Viceroy of Peru (lately published 
in the Journal of the Royal Geographical Society), wherein 
it is stated that “the first colony of the Spaniards had not 
long been settled there when it was almost totally destroyed 
by the same dreadful earthquake which, in the year 1751, 
overthrew the city of Conception in Chile: with the earth- 
quake the sea rose and overwhelmed the houses, most of which 
had unfortunately been built along the shore. Thirty-five 
persons perished from this calamitous event, and amongst 
them the governor with his wife and children.” 
It is unnecessary for me to repeat, that in the great earth- 
quake of 1822, on which there has been so much discussion, 
the sea is said to have been agitated in an extraordinary de- 
gree. Mrs. Graham, in her Journal, tells us that “ on the 
night of the 19th of November, during the first great shock, 
the sea in Valparaiso Bay rose suddenly, and as suddenly re- 
tired, in an extraordinary manner, and in about a quarter of 
an hour seemed to have recovered its equilibrium.” 
She further mentions having heard from the officers on 
board Lord Cochrane’s ship, that when His Lordship “ and 
others threw themselves immediately into a boat to go to the 
assistance, if help were still possible, of the sufterers, the 
rushing wave landed them higher than any boat had been be- 
Sore, and they then saw it retire frightfully, and leave many of 
the launches and other small vessels dry.”
