From Callao to Guayaquil the longitudes depend upon Mr. Usborne's survey, in the Constitución.
He had three chronometers fixed on board the vessel, and one which was used for
observations ; all four were good watches. If his whole meridian distance between Guayaquil
and Callao is incorrect, the error, whatever it may he, must be distributed equally along that
portion of coast, but I do not think there is an error of two miles ; probably, indeed, there is not
near so great a deviation from truth, as Mr. Usborne landed for observations continually, and
carried a connected triangulation from Callao to Puná.

I n the foregoing Table, every position, variation, and notice of tide, is the result of observations
made by officers of the ÀdvenYuie or the Beagle, therefore they are, strictly speaking, original,
and have no reference whatever to observations made by other persons , . . „1.«
An explanation of the methods and instruments used, and of the basis on which the longitudes,
especially, are founded, is given, in an abridged form, at the end of the Appendix
The positions of those points only are given which are considered to be, '" f -
satisfactorily ascertained by actual observation on shore, or well connected by triangulation to those
stations at which the artificial horizon was used. .
Where tidal notices are given opposite to summits of mountains or P f / ^ ^ ^ f ^ ^ X i i e ;
tance from the sea, it is to be understood that they refer to a point at which the sea appioaches
nearest to that specified.
