CONCLUDING REMARKS. As you read his able essay remember there are four other sets of nerves equal to, and just as important in their divisions of life, which are the motor, nutrient, voluntary and involuntary. All of which you as an engineer must know, and by proper adjustment of the body give them unlimited power to perform their separate and united parts in sustaining life and health. Now as I have tried to place into your hands a compass, flag and chain that will lead you from effect to cause of disease in any part or organ of the whole abdomen I hope that many mysteries which have hung over your mental horizon will pass away, and give you abiding truths, placed upon the everlasting rock of cause and effect. You have as little use for old symptomatology as an Irishman has for a cork when the bottle is empty. Osteopathy is knowledge, or it is nothing. CHAPTER XVII. OBSTETRICS.

OVERLOADING. When in the course of human events and actions of life, a woman disregards the laws of nature to such an extent as to overload the stomach beyond its powers and limits; or another way to present the thought, we will say, if you fill the stomach so full as to occupy all space, or so much of the space as to cripple the laws of digestion and retain the food, the decomposition sets up an irritation of the nerves of mucous membrane to such a degree as to cause sickness and vomiting, or any other method of disgorging the stomach, which is the natural process to unload an overloaded vessel. When the nerves cannot take up nutrition, they will then take up destruction and other elements which are detrimental to the process of nutrition, and there is no other process for relief but to unload. The loading that has been deposited in the stomach was for the purpose of sustaining a being. The stomach itself is a sack. When filled to its greatest capacity, it irritates all the surroundings, and in return they irritate the stomach. Thus it unloads naturally for relief. Now we wish to treat of another vessel similar in size, similar in all its actions, which receives nourishment for a being, which nourishment is contained in the blood, and conveyed from the channels commonly known as uterine arteries. To all intents and purposes this nourishment is taken there to sustain animal life, after having constructed the machinery then it appropriates the blood to the growth and existence of a human being. One is the womb, the other the stomach. The placenta in the womb is provided with all the machinery necessary to the preparation of blood, such as is used for all purposes in forming and developing a child.
