The Field of Study
We wish to know the relation existing between each part of the Nerve System and other parts and between each part and the other organs of the body. Especially we wish to understand the relation between each part of the Nerve System and the spinal column, by which permanent subluxations of the latter interfere with the former’s action and therefore with the peripheral organs.
This requires a general knowledge of anatomy, physiology, and pathology which we shall presuppose the reader to possesses so that we may present only facts to which his attention should be particularly called. Let us begin with the relation of nerve tissue to other tissues where this relation can be most clearly comprehended, namely, with the development of the human embryo.
