It provides a complete system of connections throughout the body, thereby bringing all parts into communication. The present chapter deals with the first of these conditions; the chapter following, with the second. *The Nerve Skeleton.*—If all the other tissues are removed, leaving only the nervous tissue, a complete skeleton outline of the body still remains.
The task was not easy, but, in the long run, it was accomplished. Not alone was it shown that the nerve centre requires a measurable time for its operations, but much was learned as to conditions that modify this time.
And he went to his case of instruments. "You are not going to extract it, doctor!" I rose from the operating chair in alarm. "Oh no, no, madam! I am only going to put something into it, to destroy the sensibility of the nerve, previous to preparing it for being filled. The tooth can still be preserved. We will know in a minute or two whether all the difficulty lies here."
For instance, if the cell be hungry, thirsty, cold or in pain, it telegraphs these sensations to headquarters in the brain or spinal cord and from there directions necessary to comply with the needs of the cell are sent forth in the form of nerve impulses to the centers controlling the circulation, the food and heat supply, the means of protection, etc.
In the field of natural history we have been led to think the point at issue is not man's individuality, but correct observation a true report of the wild life about us. Is one to give free rein to his fancy or imagination; to see animal life with his "vision," and not with his corporeal eyesight; to hear with his transcendental ear, and not through his auditory nerve?
He had scarcely settled himself in this position when Fred Munson changed his own. Rising from the ground where he had lain so long, he stepped over the ridge, and advanced directly toward the redskin, who harbored no suspicion that there was any of his race in his neighborhood. The plan the lad had resolved upon required nerve, resolution and quickness.

For a moment Tom and his chums stood looking at the somewhat bewildered farmer, and then Tom spoke. "You've got a lot of nerve!" he said cuttingly. "I should say so," added Bert.
In the last quarter of the night, at the North Springs, when the storm had spent itself and the white moon looked down on a drenched and flood-washed earth, the 'Ramblin' Kid dropped his rope over the head of the Gold Dust maverick barely twenty feet ahead of the horse he rode conquered by the superior nerve, muscle and endurance of Captain Jack, still the greatest outlaw the Kiowa range had ever known!
When her father laughed at her, she told him that horses often suffer terrible pain from their teeth, and that sometimes a runaway is caused by a metal bit striking against the exposed nerve in the tooth of a horse that has become almost frantic with pain.
He supposed he must have been; otherwise, why was he lying there wherever he might be on his back, with his head bandaged and racked with pain, and with no strength in him? Ill! of course he was; every nerve in his body bore testimony to the fact. But where was he? what was the matter with him? and whose was this gentle, tender voice that somehow seemed so familiar that questioned him?
