composition of the human body includes really sixteen elements in all,
oxygen is the only one used in its natural state. I give first the
elements as they exist in a body weighing about one hundred and fifty-four
pounds, this being the average weight of a full-grown man; and add a
table, compiled from different sources, of the composition of the body as
made up from these elements. Dry as such details may seem, they are the
only key to a full understanding of the body, and the laws of the body, so
far as the food-supply is concerned; though you will quickly find that the
day's food means the day's thought and work, well or ill, and that in your
hands is put a power mightier than you know,--the power to build up body,
and through body the soul, into a strong and beautiful manhood and
womanhood.

1. Oxygen, a gas, and supporter of combustion, | | |
weighs | 103 | 2 | 335
| | |
2. Carbon, a solid; found most nearly pure in charcoal. | | |
Carbon in the body combines with other | | |
elements to produce carbonic-acid gas, and by | | |
its burning sets heat free. Its weight is | 18 | 11 | 150

3. Hydrogen, a gas, is a part of all bone, blood, and | | |
muscle, and weighs | 4 | 14 | 0
