These cells are constantly at work, performing all the duties of the body, each having its own particular work to do—and doing it to the best of its ability. Some of the cells belong to the "reserves" and are kept under "waiting orders" ready for some sudden demand of duty. Others belong to the army of active workers of the cell-community and manufacture the secretions and fluids needed in the varied work of the system. Some of the cells are stationary—others remain so until needed, when they manifest motion—others are constantly on the move, some making regular trips and some being rovers. Of these moving cells some perform the work of carriers, some move from place to place doing odd jobs, and others do scavenger work, and still another class belong to the police force, or army, of the cell-community. Cell-life in the body may be compared to a large colony, operated on a co-operative plan, each cell having its own work to do for the common good, each working for all, and all working for the common welfare. The cells of the nervous system carry messages from one part of the body to the brain and from the brain to another part of the body, being living telegraph wires, as the nerves are composed of minute cells in close contact with each other, having small projections which are in contact with similar projections from other cells, so that they
