الصفحة 113 - ... matter, in warm climates, to study moderation in eating, and men can bear hunger for a long time under the equator; but cold and hunger united very soon exhaust the body. " The mutual action between the elements of the food and the oxygen conveyed by the circulation of the blood to every part of the body is the source of animal heat. " All living creatures whose existence depends on the absorption of oxygen possess within themselves a source of heat independent of surrounding objects.
الصفحة 113 - Food is either applied in the increase of the mass of a structure (ie, in nutrition), or it is applied in the replacement of a structure wasted (ie, in reproduction). The primary condition for the existence of life is the reception and assimilation of food. But there is another condition equally important — the continual absorption of oxygen from the atmosphere. All vital activity results from the mutual action of the oxygen of the atmosphere and the elements of food.
الصفحة 153 - Dr. Binns says the discovery is due to Mr. Gardner : — " Horn to procure sleep. — Let him turn on his right side ; place his head comfortably on the pillow, so that it exactly occupies the angle a line drawn from the head to the shoulder would form ; and then, slightly closing his lips, take rather a full inspiration, breathing as much as he possibly can through the nostrils.

الصفحة 153 - He must depict to himself that he sees the breath passing from his nostrils in a. continuous stream ; and the very instant that he brings his mind to conceive this apart from all other ideas, consciousness and memory depart, imagination slumbers, fancy becomes dormant, thought subdued ; the sentient faculties lose their susceptibility ; the vital or ganglionic system assumes the sovereignty ; and, as we before remarked, he no longer wakes, but sleeps.

الصفحة 117 - The regulator and the air passages open, and the machine supplies itself with more coals. The body, in regard to the production of heat and of force, acts just like one of these machines. With the lowering of the external temperature, the respirations become deeper and more frequent ; oxygen is supplied in greater quantity and of greater density ; the change of matter is increased, and more food must be supplied, if the temperature of the body is to remain unchanged.
