establishment which employs several workmen may also be an organization.
The article manufactured provides the common purpose toward which all
strive; and, in the assignment of different kinds of work to the
individual workmen, the principle of division of labor is carried out. For
the same reason a school, a railway system, an army, and a political party
are organizations.

An organization of a lower order of individuals than these human
organizations is to be found in a hive of bees. This is made up of the
individual bees, and these, in carrying on the general work of the hive,
are known to practice the division of labor.

in the related work of the different organs. That it is made up of minute,
but individual, parts will be shown in the chapter following. That it
carries on a _general work_ which is accomplished through the combined
action of its individual parts is revealed through an extended study of
its various activities. _The body is an organization._ Moreover, it is one

*Summary.*—Viewed from the outside, the body is seen to be made up of
divisions which are more or less familiar. Viewed internally, it is found
to consist of different kinds of materials, called tissues. The tissues

construction of the body and in carrying on its work. The working parts of
