INDEX

within these are two thinner folds, the _labia minora_ or _nymphae_. 

These, together with the _clitoris_, situated just above, are extremely 

sensitive organs, being the chief seat of sexual sense in the female. 

At the lower part is the opening to the vagina, which in the virgin 

is usually partially guarded by a thin membrane, the _hymen_. This is 

not always a reliable test of virginity, however, as commonly regarded, 

since it may be destroyed by disease or accident, and may exist even 

after the occurrence of pregnancy. 

 

The vagina extends from the vulva to the lower end of the uterus, which 

it incloses, passing between the bladder and the rectum. The lower 

extremity of the uterus presents a small opening which leads into its 

interior. Upon either side, at its upper and larger end, is a minute 

opening, the mouth of the Fallopian tube. The latter organs extend from 

the uterus outward nearly to the ovaries, toward which they present 

a number of small filaments, one of which is in contact with each ovary. 

These filaments, together with the interior of the tubes, are covered 

with a peculiar kind of cells, upon which are minute cilia, or hairs, 

in constant motion. Very curiously, they all move in the same direction, 

toward the cavity of the uterus. When an ovum escapes from the ovary 

in connection with menstruation, it is by these delicate hairs 

propelled along a filament of tissue to the Fallopian tube, and thence 

by the same means is conveyed to the uterus. It may come in contact 

with the zoosperms at any point between the ovary and the lower orifice 

of the uterus, and thus undergo fecundation. 

 

Puberty.--For a certain period after birth, the sexual organs remain 

in a partially developed condition. This period varies in duration with 

different animals; in some cases being very brief, in others, 

comprising several years. Upon the attainment of a certain age, the 

individual becomes sexually perfect, and is then capable of the 

generative act. This period is called puberty. In man, puberty commonly 

occurs between the ages of ten and fifteen years, varying considerably 

in different climates. In this country, and in other countries of about 

the same latitude, puberty usually occurs at the age of fourteen or 

fourteen and one-half years in females, and a few months later in males. 

In cooler climates, as in Norway and Siberia, the change is delayed 

to the age of eighteen or nineteen years. In tropical climates it is 

hastened, occurring as early as nine or ten years. In warm climates 

it is no uncommon thing for a girl to be a mother at twelve; and it 

is stated that one of the wives of Mahomet was a mother at ten. 

 

Other causes besides climate tend to hasten the occurrence of this 

change, as habits, temperament, constitutional tendency, education, 

and idiosyncrasy. 

 

Habits of vigorous physical exercise tend to delay the access of puberty. 

For this reason, together with others, country boys and girls generally 

mature later than those living in the city by several months, and even
