When we use the word "disease," we mean anything that makes an unnatural showing in the body by pain, overgrowth of muscle; gland; organ; physical pain; numbness; heat; cold; or anything that we find not necessary to life and comfort. I have no wish to rob surgery of its useful claims, and its scientific merits to suffering man and beast. Such is not my object, but to place the Osteopath's eye of reason on the hunt of the great whys that the knife is useful at all, I am sure it comes often to remove growths and diseased flesh and bone that have gotten so by man's ignorance of a few great truths. 1st, If blood is allowed to be taken to a gland or organ, and not taken away in due time the accumulation will become bulky enough to stop the excretory nerves and cause local paralysis; then the nutrient nerves proceed to construct tumors, and on and on until there is no relief but the knife or death. Had this blood not been conveyed there, it would not be there at all, either in bulk or less quantities. Had it simply done its work and passed on we could have no material to grow such abnormal beings. If a tumefaction appears in one side, and not in the other, why so? and why is there no growth in one side the same as the other? It takes no great effort of mind to see that the veins did not receive and carry off the blood, and a growth was natural, as the condition could not do otherwise and be true to nature. Thus man's ignorance has made a condition for the knife. Had he taken the hint and let the blood pass on when its work was done, he would not have to witness the guillotine of death to his patients, whose early pains told him a renal vein or some vessel below the diaphragm was ligated by an impacted colon, or a few ribs pulling and bringing diaphragm down across vena cava and thoracic duct and causing excitement or paralysis of solar plexus, or any other nerves that pass through diaphragm with blood to and from heart and lungs.
