at birth, but they are relatively insignificant, and it is not until the great developmental changes peculiar to puberty occur that they begin to exercise their influence on the shape of the bones. This is proved by the fact that in those rare cases in which the internal organs of generation are absent, or fail to develop, there is a corresponding failure in the pelvis to alter into the normal adult shape. The muscles of the growing girl partake in the rapid growth and development of her bony framework. Sometimes the muscles outgrow the bones, causing a peculiar lankiness and slackness of figure, and in other girls the growth of the bones appears to be too rapid for the muscles, to which fact a certain class of "growing pain" has been attributed.
Another part of the body that develops rapidly during these momentous years is the bust. The breasts become large, and not only add to the beauty of the girl's person, but also manifestly prepare by increase of their glandular elements for the maternal function of suckling infants.
Of less importance so far as structure is concerned, but of great importance to female loveliness and attractiveness, are the changes that occur in the clearing and brightening of the complexion, the luxuriant growth, glossiness, and improved colour of the hair, and the beauty of the eyes, which during the years which succeed puberty acquire a new and singularly attractive expression.
The young girl's hands and feet do not grow in proportion with her legs and arms, and appear to be more beautifully shaped when contrasted with the more fully developed limb.
With regard to the internal organs, the most important are those of the pelvis. The uterus, or womb, destined to form a safe nest for the protection of the child until it is sufficiently developed to maintain an independent existence, increases greatly in all its dimensions and undergoes certain changes in shape; and the ovaries, which are intended to furnish the ovules, or eggs (the female contribution towards future human beings), also develop both in size and in structure.
Owing to rapid growth and to the want of stability of the young girl's tissues, the years immediately succeeding puberty are not only those of rapid physiological change, but they are those during which irreparable damage may be done unless those who have the care of young girls understand what these dangers are, how they are produced, and how they may be averted.
With regard to the bony skeleton, lateral curvature of the spine is, in mild manifestation, very frequent, and is too common even in the higher degrees. The chief causes of this deformity are:
(1) The natural softness and want of stability in the rapidly growing bones and muscles;
(2) The rapid development of the bust, which throws a constantly increasing burden on these weakened muscles and bones; and
(3) The general lassitude noticeable amongst girls at this time which makes them yield to the temptation to stand on one leg, to cross one leg over the other, and to write or read leaning on one elbow and bending over the table, whereas they ought to be sitting upright. Unless constant vigilance is exerted, deformity is pretty sure to occur--a deformity which always has a bad influence over the girl's health and strength, and which, in those cases where it is complicated by the pathological softness of bones found in cases of rickets, may cause serious alteration in shape and interfere with the functions of the pelvis in later life.
2. Changes in the Mental Nature.--These are at least as remarkable as the changes in the bodily framework. There is a slight diminution in the power of memorising, but the faculties of attention, of reasoning, and of imagination, develop rapidly. Probably the power of appreciation of the beautiful appears about this time, a faculty which is usually dormant during childhood. More especially is this true with regard to the beauty of landscape; the child seldom enjoys a landscape as such, although isolated beauties, such as that of flowers, may sometimes be appreciated.
As might be anticipated, all things are changing with the child during these momentous years: its outlook on life, its appreciation of other people and of itself, alter greatly and continuously. The wonderfully rapid growth and alterations in structure of the generative organs have their counterpart in the mental and moral spheres; there are new sensations which are scarcely recognised and are certainly not understood by the subject: vague feelings of unrest, ill-comprehended desires, and an intense self-consciousness take the place of the unconscious egoism of childhood.
The processes of Nature as witnessed in the season of spring have their counterpart in the changes that occur during the early years of adolescence. The earth warmed by the more direct rays of the sun and softened by recurring showers
