It has been said that were man to discover heaven (a clean and healthy locality) he would at once convert it into a hell (a vile and filthy one). Man is possessed of an organism of whose constituent elements water forms over eighty per cent. The alvine discharges ought to contain the same percentage of water, if not more. The mucous membrane and skin, to be kept clean, soft, fresh, plump, moist, and free from odors, require their appropriate irrigation. Man may keep himself clean, both inside and out, by irrigating himself before each meal daily. The well-watered and well-washed body and brain constitute a heaven on earth for the indwelling spirit that needs these for its manifestation. It does seem sometimes that man in his ignorance gets nothing right except to walk forward instead of backward. Even so, most likely he walked on all fours for ages, judging from his progress to date, before he learned to walk on his hind legs. To-day we find him self-poisoned, auto-intoxicated, a gastro-intestinal neurasthenic. His bowels are filled and stretched with ancient feces and gases, and his stomach is burdened with undigested food and tenacious mucus. The average man’s scanty excreta from the bowels are dry, hard, lumpy, and foul, exhaling a noxious odor; and these excretions may be passed once a day, or once in two or three days, or with some persons too often, should diarrhea supervene. Two-thirds to three-fourths of the fecal mass is absorbed by the system every day; and this absorption is accompanied more or less constantly by symptoms of indigestion, biliousness, uric acid, and many other distressful conditions. His breath and the exhalations of a garbage-can are much alike; in fact they are twins, the only difference between the human and metallic receptacles being that one is capable of walking and the other is not. Both manifest the same conditions. His mucous membrane is covered more or less with catarrhal discharges, which result in granulated deposits, especially near the orifices. The skin is often sallow, dry, yellow, scaly, flabby. The hair is dry, non-oily, with a scaly scalp, and often there is a loss or total lack of hair. The teeth are decayed, the gums are found to recede, and the eyes, muscles, joints, etc., are more or less affected by calcareous deposits.
