which we have described as occurring in males; and although there is neither the change of voice, nor the production of hair on the face, so remarkable in the other sex, yet the body enlarges in volume, the breasts swell with exuberance, and the excess of vitality no longer required for general growth, invests her limbs with those rounded and graceful forms, which have so universally constituted the theme of the poet, and the admiration and study of the artist: but the most remarkable change which the female system undergoes at this period is indicated by the commencement of a periodical sanguineous discharge[273] from the vessels of the uterus, and which from the monthly interval that it observes has received the name of _Menses_. The period of life at which this change takes place is under the control of various moral and physical circumstances, as climate, temperament of the individual, habits of living,[274] &c. In tropical climates puberty takes place at an earlier period than in northern latitudes; in Greece, the Corea, Indostan, and Java, girls begin to menstruate at eight, nine, or ten; in Spain, Sicily, and the Southern part of Europe, at twelve; but advancing to the northern climes, there is a gradual protraction of the time until we come to Lapland, where women do not menstruate till they arrive at a maturer age, and then in small quantities, at long intervals, and sometimes only in summer.[275] This difference in the time of life at which puberty takes place, has been ingeniously assigned by _David Hume_ as the reason why women in hot climates are almost universally treated as slaves; and why, on the contrary, their influence is so powerful and extensive in colder regions; for in the former, woman may be said to be in the zenith of her beauty while she is yet a child in understanding, and long before her intellect is matured she ceases to be an object of love; but in temperate countries her personal charms and intellectual endowments are simultaneous in their progress to perfection; the united force of her beauty and mental qualities is irresistible, and man voluntarily pays to her the homage which her powers are so well calculated to command[276]. There are, moreover, many cases on record[277], in which both males and females have prematurely arrived at the stage of puberty; a most remarkable instance of this precocity is recorded[278] by Mr. Anthony White, in the history of Philip Howorth, and the author of the present work can bear testimony to the correctness of the statement, for he had frequent opportunities of seeing him, and of tracing from time to time the constitutional changes which so rapidly succeeded each other in the first two years of his existence. Dr. Wall has presented us with a similar instance of precocity in a female infant, in whom the menstrual flux appeared at the age of nine months[279].
