But few questions remain to be asked by the philosophical navigator when he sets sail to go to the cause of flux. Would he go to blood supply? Certainly, there must be supply previous to deposit. Reason would cause us to combine the fact that blood must be in perpetual motion from and to the heart during life, and that law is the fiat of all nature which is indispensable and absolute. Blood must not stop its motion nor be allowed to unduly deposit, as the heart's action is perpetual in motion. The work is complete of the heart if it delivers blood into the exploring arteries. Each division must to do its part fully as a normal heart does, or can in the greatest measure of health; and a normally formed heart is just as much interested in the blood that is running constantly for repairs and additions, as the whole system is on the arteries for supply. Thus you must have perfection in shape first, and from it to all parts as far as an artery reaches. All hindrances must be kept away from the arteries great and small. Health permits of no stopping of blood in either the vein or artery. If an artery cannot unload its consents a strain follows, and as an artery must have room to deposit its supplies it proceeds to build other vessels adjacent to the points of obstruction. ANEURISMS. Some are builded to enormous sizes. We call them aneurisms or accommodation chambers, builded by nature's constructing ability of the arteries as deposits for blood. The artery should pass farther on, thus you by reason must know an obstruction has limited the flow of blood, and the tumor is only an effect, and obstruction is the cause of all abnormal deposits, either from vein or artery. Unobstructed blood cannot form a tumor, nor allow inharmony to dwell in any part of the system. Flux is an effect, blood supply and circulation both at variation from normal. An artery finds veins of bowels irritated and contracted to such degree that arterial blood cannot enter veins with cargo of blood at all, and deposits its blood at terminal points in mucous membrane of bowels, and when membrane fails to hold all blood so delivered, then the first blood which dies of asphyxia finds an outlet into the bowels to be carried off and out by peristaltic actions. Thus you have a continuous deposit and discharge for arterial blood until death stops the supply. CHAPTER XII. SCARLET FEVER AND SMALLPOX.
