Before you leave that wisely constructed neck, I want to press and imprint on your minds in the strongest terms that the wisest anatomist, and physiologist, the oldest and most successful Osteopath knows only enough of the neck, and its wondrous system of nerves, blood and muscles and its relation to all above and below it, to say, "From everlasting to everlasting thou art great, O Lord God Almighty!" Thy wisdom is surely boundless, for I see that man must be wise to know all about the neck, for we find by a twist of neck, we may become blind, deaf, spasmodic, lose speech and memory, and all that is known as the joys of man. On that division of the body all action of arms, legs, chest and all muscles get their life--power and motion. Think for a moment of the thousands and tens of thousands of large and small fluid vessels that pass to and from heart and brain, to every organ, bone, fibre, muscle and gland, both large and small, receiving and appropriating the substances as prepared in the chemical laboratory; so wisely situated, and so exact in all its works in the production and application of all substances in the body. ORDER OF TREATMENT. The reader will begin with the brain or head because I want to start with the head; first give such diseases as belong to that division of the body. Then the neck, chest, abdomen and pelvis. Thus we have five divisions in regular order, beginning with the head and finishing with the sacrum. The reader will find diseases of eye, ear, tongue, nose, face, scalp and hair under the chapter treating of the head. Next in regular order will be the division of the neck, with diseases of tonsils and glands of neck, swallow, trachæ, nerves, blood vessels and muscles, fascia and lymphatics, superior cervical ganglion and other nerves of the neck, as they affect vitality in diseases. Then we pass on to third division, with diseases of lung, heart, pericardium, and pleura, with all parts of chest. Then abdomen, liver, stomach and bowels, and all organs with resisting power of diaphragm. Fifth, pelvis, with its great supply of nerves, blood and other fluids. These give us cause to halt and seat the mind for a long season of observation. A great field opens at this point for the observing thinker. THE PELVIS. In the pelvis we find a system of nerves and arteries with blood for local supply, besides blood to construct womb, bladder, rectum, colon, cellular system and all the muscles of that cavity (the pelvis) all of which comes from arteries and branches above. We think it is not necessary to name them only in bulk, to a student versed in anatomy. Perhaps less is known of the pelvic system and its functions than any division of the body, and for that reason I have felt that we should know all that is possible to be learned. I believe more ignorance prevails to-day of internal causes of diseases than would if we reasoned that the pelvic nerves and vessels had much to do in forming the abdominal viscera.
