Seite 178 - ... 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.
Seite 177 - 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.
Seite 225 - 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. This, however, is not absolutely necessary, as some persons breathe always through their mouths during sleep, and rest...
Seite 225 - The attention must now be fixed upon the action in which the patient is engaged. He must depict to himself that he sees the breath passing from his nostrils in a continuous stream...
Seite 177 - ... Physiology has sufficiently decisive grounds for the opinion, that every motion, every manifestation of force, is the result of a transformation of the structure or of its substance ; that every conception, every mental affection, is followed by changes in the chemical nature of the secreted fluids ; that every thought, every sensation, is accompanied by a change in the composition of the substance of the brain.
Seite 225 - 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.
Seite 183 - 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.
