Economic Digestion-Ash (solid excreta), as a daily average for an adult of 140 lbs. (10 stone; 63.5 kilos), including moisture, when released, should not weigh more than two ounces (56.70 grams). An average of less than one half this amount of waste has been secured in test experiments.

The true test of healthy Z is absence of odour and completeness, ease and cleanliness of delivery. Frequency or otherwise, does not so much matter. Quantity too, is not so important; but with foul odour there is disturbance, strain and danger.
The normal man is a cleanly being with all excreta inoffensive; and by these tokens he may be his own private judge.
Why is it that barn-yards are tolerable to the human senses while open dépôts of human excreta are fever-breeding nuisances and intolerable to beasts and humans alike?
This curse of putrid excreta caused more deaths from enteric fever during the Boer War in South Africa than all other causes. It is equally a menace to health and even to life while being formed and carried in the body.
Fourth
Offensive excreta are quite certain evidence of neglect of the self-controllable parts of our own nutrition. They are the tell-tale condemnation of ignorance or carelessness. Each person should learn to read the true bulletins of his health conditions in his waste-products of digestion.
