The repair of Bone, Blood Vessels, and Peripheral Nerves is more conveniently considered in the chapters dealing with these structures. #Rate of Healing.# While the rate at which wounds heal is remarkably constant there are certain factors that influence it in one direction or the other.

The cold water will reduce the temperature and tone the peripheral blood vessels; the hot water, if the temperature is low and the skin moist and flabby, will cleanse it and also tone the peripheral blood vessels.

Twelve per cent of the cases were of acute glaucoma; 61.5 per cent of chronic inflammatory glaucoma, and 9 per cent of simple glaucoma. The rest of the operations were done in other forms of the disease. In more than half the cases the usual iridectomy was performed; in 30 per cent the procedure was peripheral; in 4 per cent there was no iridectomy.

"I would also go farther, and express the opinion, that peripheral influences of an extremely powerful and continuous kind, where they concur with one of those critical periods of life at which the central nervous system is relatively weak and unstable, can occasionally set going a non-inflammatory centric atrophy, which may localize itself in those nerves upon whose centres the morbific peripheral influence is perpetually pouring in.

In a deprivation of calcium we have, in all probability, the explanation of the increased irritability of peripheral nerves and of the tendency to convulsive seizures of all sorts which is a common accompaniment of the condition. Convulsions, laryngismus stridulus, tetany, or carpopedal spasm are all frequently met with.

*The Peripheral Division.*—The peripheral division of the nervous system includes all the nervous structures found outside of the brain and spinal cord. These consist of the cranial, spinal, and sympathetic nerves, and of various small ganglia, all of which are closely connected with the central system.

This is especially indicated at the very beginning of the disorder. Small animals should be given a good bed. A very light, easily digested ration should be fed. An occasional physic should be administered. Strychnine and iodide of potassium may be given. Cold applications to the back are indicated. What organs comprise the central portion of the nervous system? Peripheral portion?

At the first stage, ether, which in itself has a purely peripheral orientation, becomes linked to some all-relating point; at the second stage, the various ether-activities, already point-related, are brought into some characteristic interrelationship so as to become the cause of a particular formative action in the material realm; at the third stage, the etheric aggregate thus organized receives the impulse to link itself with some particular portion of ponderable matter.

A weak heart generally needs the blood pressure strengthened, but a compensating heart rarely needs an increase in peripheral blood pressure, and any great increase from any reason is a disadvantage to such a heart.

If a patient had already valvular disease from a previous endocarditis, and during this attack insufficiency of the heart was evidenced by pendent edemas, digitalis Should be administered; but it probably should not be given to other patients during the acute period of inflammation. During rheumatism the peripheral blood vessels are generally dilated and the skin perspires profusely.
