of Mexico, owing to the friendly assistance and hospitality which they
received there. With this aid they were enabled to accomplish much more
than usually falls to the lot of travellers in so limited a period; and
they had the great advantage too, of being able to substantiate or
correct their own observations by the local knowledge and experience of
their friends and entertainers.

Visiting Mexico during a lull in the civil turmoil of that lamentably
disturbed Republic, they were fortunate in being able to avail
themselves of that peaceable season in making excursions to remarkable
places and ruins, and examining the national collection of antiquities,
and other objects of interest,--an opportunity that cannot have
occurred since owing to the recommencement of civil war in its worst
form.

The following are some of the chief points of interest in these Notes
on Mexico, which are either new or treated more fully than hitherto:

1. The evidence of an immense ancient population,
shewn by the abundance of remains of works of art
(treated of at pages 146-150), is fully stated
here.

2. The notices and drawings of Obsidian knives and
weapons (at page 95, &c., and in the Appendix) are
more ample than any previously given.

3. The treatment of the Mexican Numerals (at page 108)
is partly new.
