This is, however, but the population of the chief town or capital. The entire intendency of Pueblos de los Angeles contained, in 1793, 508,098 souls. Of this number, 373,752 were Indians of pure blood, divided into 187,531 males, and 186,221 females. There were also 77,908 of the mixed race, divided into 37,318 males, and 40,590 females. But 54,980 were Spaniards, or whites, exclusive of 585 secular ecclesiastics, 446 monks, and 427 nuns. This preponderance of the native Indian population is still more striking in the government of Ilaxcala, which, of course, includes the capital above named. In 1793, it contained a population of 59,177 souls; of which, 42,878 were Indians, divided into 21,849 males, and 21,029 females. The town is governed by a Cacique, and four Indian Alcaldes, who represent the ancient heads of the four quarters, still called Teepectipac, Ocotelalco, Quiahtuitztlan, and Tizatlan. By virtue of a royal cedula of 16th April, 1585, the whites have no seat in the municipality. The Cacique, or Indian Governor, enjoys the honors of an _alferez real_. Notwithstanding the zeal of a Spanish intendant general, the progress of the inhabitants in industry and prosperity has been extremely slow. The secret of this is, perhaps, revealed in the fact that four fifths of the whole property belongs to mort-main proprietors, that is to say, to communities of monks, to chapters, corporations, and hospitals. Their trade is also depressed by the enormous price of carriage from the table lands, and the want of beasts of burden. The geology and antiquities of this part of Mexico, are equally interesting. The intendency of Puebla is traversed by the high cordilleras of Anahuac, which, beyond the 18th degree of latitude, spreads into a plain, elevated from 1,800 to 2,000 metres above the level of the ocean, or from 5,905 to 6,561 feet. In this intendency is also the Popocatepetl, the highest mountain in Mexico. Humboldt's measurement of this volcano makes it 600 metres (1,968 feet,) higher than the most elevated summit of the old continent. It is, indeed, only exceeded between Panama and Behring's Straits, by Mt. St. Elias.
