First

In adults; or, in children after the eruption of teeth and the ingestion of solid food: The non-liquid and non-gaseous waste of the human body, which, in its normal state, is not offensive, should be very small, in quantity, should be pillular in form, either separate or massed together; should have no odour when released, should take on no odour on standing, should be entirely aseptic (non-poisonous); should drop freely from the exit, leaving nothing behind to wash or wipe away. It may not be collected in the intestines of full-grown and elderly persons, when normal, as above, in sufficient quantity to require or necessitate emptying oftener than from twice a week to once in two weeks; according to age, activity, etc.; and should neither invite nor justify the description "it is not that which goeth into a man that defileth him but that which cometh out".

Second

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.

Third

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 depdts 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 is the form the body must assume to render emptying of the digestion-ash natural and easy. Man was built to squat on his heels in defecating, and sitting erect on a modern seat is like trying to force a semi-solid through a kinked hose. Healthy Human Excreta are no more Offensive than Moist Clay and have no more Odour than a Hot Biscuit.

A. B. - Z. Figure To Illustrate The "Division Of Labour"

First. A. Psychic Environment Mental State

This involves:

Appetite (to select for) Attention (to prepare for) Appreciation (to assist in)

Digestion

(Absolutely necessary to secure secretion and flow of the digestive juices: Vide Pawlow and Cannon).

Second. B. Buccal- Digestion Mouth-Treatment

This involves:

Mechanical (teeth) Chemical (salival)

Thoroughness

(Absolutely necessary to secure complete digestion and avoid the putridity incident to bacterial decomposition: Vide Campbell and Van Some-ren).

Intermediate

The twenty-three letters between "B" and "Z" represent but an inadequate proportion for the spelling of the enormous share Nature assumes in our welfare, marvellously performing her forty-seven forty-eighths share in the secret laboratory of the alimentary canal.

Third. Z

The true chemical end-point of digestion, by which each self-respecter may know how well he has respected his "A" and his "B," and how faithfully he has performed his one forty-eighth share in the promotion of his own most fundamental interest.
