Of not less importance are the investigations upon the excess observed in one sex over the other. Before the appearance of Humboldt's work it was the opinion that in the New World nature did not follow the same law of equilibrium in the difference between the sexes as in Europe, and especially that in the tropical regions, the number of females exceeded greatly that of the males. Baron Humboldt combated this notion and demonstrated its error. He presents in his political essay upon New Spain a table of the population of eight Intendencies, in which it appears that out of 1,352,835 inhabitants there were 687,935 males and 664,900 females, which establishes a relative proportion of 100 to 95. In the Tablas Geografico politicas, already cited, it is expressly said that in New Spain, in the Intendencies of the tierras frias, or cold regions, as well as in those of the tierras calientes, or hot regions, the population inclines to a preponderance of males. Don Fernando Navarro y Noriega gives in his tables of population 71,642 more males than females; and, in the account of the taxes made by order of the government in 1781, it appears that the excess is still in favor of males, though in a much less proportion than assigned by Baron Humboldt. We present the following table, prepared in Mexico for the purpose of throwing more light on the subject:
