In the first place, through our glass, we should see the gaping wound enlarged to gigantic proportions. We should see the torn skin, tissues, lymphatic and blood vessels, glands, muscles and nerves. We would see the blood pouring forth washing away the dirt and foreign substances that have entered the wound. We would then see the messages calling for help flashing over the living telegraph wires of the nerves, each nerve-cell rapidly passing the word to its neighbor until the great sympathetic centres received the call and sounded the alarm and sent out a "hurry up" call to the cells needed for the repair work. In the meantime the cells of the blood, coming in contact with the outside air have begun to coagulate into a sticky substance, which is the beginning of the scab, the purpose being to close the wound and to hold the severed parts together. The repair cells having now arrived at the scene of the accident begin to mend the break. The tissue, nerve, and muscle cells, on each side of the wound begin to multiply rapidly, receiving their nourishment from the blood cells, and quickly a cell bridge is built up until the two severed edges of the wound are reunited. This bridging is no haphazard process, for the presence of directing law and order is apparent. The newly-born cells of the blood-vessels unite with their brothers on the other side, evenly and in an orderly manner, new tubular channels being formed skillfully. The cells of the connective tissues likewise grow toward each other, and unite in the same orderly manner. The nerve-cells repair their broken lines, just as do a gang of linemen repair the interrupted telegraph system. The muscles are united in the same way. But mark you this, there is no mistake in this connecting process--muscle does not connect with nerve, nor blood-vessel with connective tissue. Finally, the inner repairs and connections having been completed, the scab disappears and the cells of the outer skin rebuild the outer covering, and the wound is healed. This process may occupy a few hours, or many days, depending upon the character of the wound, but the process is the same in all cases. The surgeon merely disinfects and cleans the wound, and placing the parts together allows the cells to perform their healing work, for no other power can perform the task. The knitting together of a broken bone proceeds along the same lines--the surgeon places the parts in juxtaposition, binds the limb together to prevent slipping, and the cells do the rest.
