162, the 30th of May 1521, on which day
Cortes dated the commencement of this memorable siege. - E.
[2] Corpus Christi fell that year, according to Clavigero, on the 30th May,
so that the occupation of Iztapalapa, by which the investment of
Mexico was completed, was on the 3d of June.
[3] The whole of this topographical account of Mexico and its approaches
is added by the editor, and has been placed in the text, distinguished
by inverted commas, as too long for a note. A plan is added,
constructed from a comparison of the maps in Diaz and Clavigero, both
evidently drawn without any actual survey, and corrected by means of
the excellent map of the vale of Mexico given by Humboldt. By means of
a great drain, made considerably posterior to the conquest, the lake
has been greatly diminished in magnitude, insomuch that the city is
now above three miles from the lake; so that the accurate map of
Humboldt does not now serve for the ancient topography of Mexico and
its near environs. - E.
[4] It is hard to guess which way the brigantines could get there, as by
the maps both of Diaz and Clavigero, the great double causeway of
Xoloc or Iztapalapa, ought to have completely prevented his
penetrating to that part of the lake.
