the animal kingdom. The sexual organs of the higher orders of plants 

are flowers. That part of the flower which produces seeds answers to 

the female; another part, which is incapable of forming seeds, answers 

to the male. The fertile and sterile flowers are sometimes produced 

on separate plants. Very frequently, they are produced upon separate 

parts of the same plant, as in the oak, walnut, and many other forest 

trees, and Indian corn. In the latter plant, so familiar to every one, 

the "tassel" contains the male flowers, and the part known as the 

"silk," with the portion to which it is attached--which becomes the 

ear--the female or fertile flowers. In a large number of species, the 

male and female organs are combined in a single flower, making a true 

hermaphrodite. 

 

Sex in Animals.--As previously remarked, individuals of opposite sex 

usually differ much more than in the character of their sexual organs 

only. Among higher animals, the male is usually larger, stronger, and 

of coarser structure than the female. The same contrast is observed 

in their mental characters. With lower animals, especially insects, 

the opposite is often observed. The female spider is many times larger 

than the male. The male ant is small in size when compared with the 

female. Nevertheless, in all classes of animals the difference in the 

structure and the functions of the sexual organs is the chief 

distinguishing character. These differences are not so great, however, 

as they might at first appear. The male and female organs of 

reproduction in man and other animals, which seem so dissimilar, when 

studied in the light shed upon this subject by the science of embryology, 

are found to be wonderfully alike in structure, differing far more in 

appearance than in reality, and being little more than modifications 

of one general plan. Every organ to be found in the one sex has an 

analogue in the other which is complete in every particular, 

corresponding in function, in structure, and usually in position. 

 

Other Sexual Differences.--In this country there is between five and 

six inches difference in height and about twenty pounds difference in 

weight between the average man and the average woman, the average man 

being about five feet, eight inches in height, and weighing one hundred 

and forty-five pounds; while the average woman is five feet, two or 

two and one-half inches in height, and weighs one hundred and 

twenty-five pounds. The relation of the sexes in height and weight 

varies in degree in different countries, but is never changed. The 

average height and weight of American men and women is considerably 

above that of the average human being. 

 

Men and Women Differ in Form.--The differences in form are so marked 

that it is possible for the skilled anatomist to determine the sex of 

a human being who has been dead for ages, by an examination of the 

skeleton alone. In man, the shoulders are broad, the hips narrow, and 

the limbs nearly straight with the body. In woman, the shoulders are 

narrow and usually rounded, and set farther back, the collar-bone being
