It may, generally, be said that the excess of one sex over the other is in inverse proportion to the latitude; or, in other words, that, as we advance from the equator, the excess of females over males decreases, until the reverse occurs as the degrees of latitude augment. We must, however, except from this rule the department or state of Tamaulipas, in which the constancy with which nature sustains the excess of males, is somewhat extraordinary. The most ancient document possessed upon the subject, relative to this State, is of the year 1793, and from this we discover that, from that year until 1807, 124 more males than females were born therein, and that 30 more females than men died during the period—
