and maladies of the tropics, are classed under this head. The tierra fria comprises the mountainous districts rising above the level of the capital up to the limit of constant snow; while the tierra templada embraces those milder middle regions not comprehended in the two other sections. Classing them by elevation in feet, we may suppose that the tierras calientes extend to between 3,000 and 4,000 feet above the level of the sea; the tierras templadas to between 4 and 8,000 feet; and that the tierras frias embrace all the remaining portions up to the region of eternal ice.
Political Divisions and Boundaries of Mexico.
It is, perhaps, more of historical or antiquarian interest, than of actual present value, to recur to the ancient divisions of the viceroyalty of New Spain. Nevertheless, there are readers who are naturally anxious to trace the territorial aggrandizement as well as the recent curtailment of Mexico, and we have, therefore, thought it proper to present a picture of the limits and apportionment of the country at several periods.
The territorial limits of that region generally called New Spain, were comprised between the degrees of 15° 58' and 42° of north latitude; and between 89° 4' and 126° 48' 45" west longitude from Paris,—calculating from the easternmost point of Cape Catoché, in Yucatan, to the extreme western limit of the land at Cape Mendocino, in California.

The limit between the United States and New Spain was defined by a treaty negotiated between the Chevalier de Onis, then Spanish minister at Washington, and John Quincy Adams, American Secretary of State, after long and learned historical as well as legal discussions of territorial rights and limits, which the student will find,
