Body Reflexes Acting on the Body

Necessity for the array of authors may be understood when one realizes the time consumed by complete neurological studies, especially careful sensory chart, special studies of posture, spasm, and successive reflexes, and selection of suitable patients, who then were studied under water by Dr. Zivin, a procedure later to be described.

Not only in surgery but in many other divisions of medicine, including neurology, a part of the huge debt of death, injury, and disease in war may be compensated by the increment of knowledge resulting from studies made available on a large scale.
