On the Reality of the Rise of the Coast of Chile. 243 
ation contained in the words quoted below, would tend to throw dis- 
credit on her whole statement. “Before I quit the subject, it may 
not be amiss to mention, that on comparing the times at which the 
successive shocks took place in Chile, as given by Mrs. Graham, and 
the other authorities to which I have had occasion to refer, the dis- 
crepancy is extraordinary.” 
Mrs. Callcott, in answer to these observations, begs the attention 
of the Society, and of Mr. Greenough himself, to the following 
pages. 
The facts detailed by her to Mr. Warburton, and stated more at 
large in her published journal, are strictly true. Mrs. Callcott had 
ample means and leisure to examine the coast at Quintero and Val- 
paraiso, places distant from each other thirty miles; and she saw the 
difference‘between the old high water marks on the cliffs, beach and 
rocks, from three to four feet higher than the high water ever reach- 
. ed again during the two months she remained in Chile, after the first 
great shock. She is indifferent whether Mr. Greenough ascribes 
this to a partial elevation of the coast of Chile, or to a change of Jev- 
el of the whole mighty Pacific Ocean, which must have extended to 
Polynesia, India and China: the fact is, that there was a change in 
the relative position of the land and water; and to save circumlocu- 
tion, Mrs. Callcott will continue to use the work raised, or elevated, 
in describing that change. 
Mrs. Callcott has reason to think, that nothing less than a similar 
catastrophe to that of the night of the 19th of November, will ever re- 
Store the land and water to their former relative positions ; especial- 
ly because other sea-shores appear at various heights, well defined 
on the cliffs of the Heradura Bay, countenancing the idea that they 
have been hoven up by successive earthquakes. Mrs. Callcott 
learned, on unquestionable authority, that the earthquake was felt 
at the same moment she felt it, at Coquimbo and Copiapo, North 
of Quintero, and at Conception, South of Valparaiso: and had rea- 
Son to believe, from general reports, that its effects extended much 
farther in both directions. Mrs. Callcott has, in her letter to Mr. 
Warburton, and in her published journal, related these facts simply ; 
but she has never, as Mr. Greenough insinuates, stated such an ab- 
surdity, as that any one set about, much less accomphshed, a regu- 
lar geological survey of an estimated area of 100,000 square miles 
On the morrow of that fearful catastrophe, or at any other time.
