The celebrated diver, Mr. Spalding, observed, that whenever he used a diet of animal food, or drank spirituous liquors, he consumed in a much shorter period the oxygen of the atmospheric air in his diving-bell; and he therefore, on such occasions, confined himself to vegetable diet.

Did it contain the oxygen essential to Tellurian lungs?

In fact, the difference vanishes with the sunshine, even in the case of the green plant; which, in the dark, absorbs oxygen and gives out carbonic acid like any animal.

He would be more astounded to learn that beneath the appearances, the changes, so alarming him, there are profound alterations in the rate at which he is taking in oxygen, burning up sugar, accumulating carbon dioxide and excreting waste byproducts through the kidneys, which are responsible for them.

They retain the hydrogen and the carbon, exhale the superfluous oxygen, and absorb little or no nitrogen.

The woman breathes less oxygen per minute and burns up less food and tissue.

The lungs will not decarbonize and purify the blood with foul air, that has been breathed over and over and lost its oxygen.

It must indeed be well nourished, and therefore the blood sent to it must be highly nutrient, capable of supplying oxygen freely.

Here it gives up its oxygen, and certain nutritive materials to build up the tissues, and receives certain products of waste, and, changed to a purple color, passes from the capillaries into the veins.

Some species grow only in contact with air, others need no more oxygen than they can obtain in the fluid or semi-fluid which they inhabit.

It drinks the oxygen in at every pore; and burns.

It here receives the oxygen from the atmosphere, and the chyle, or white blood, from the digested food, and becomes, in an instant, arterial blood, a vital principle, from which every solid and fluid of the body is constructed.

Some of its effects are to furnish the blood with chemicals that act as fuel to the muscles, assisting them to contract more vigorously, to make the lungs more active in introducing oxygen into the system, to make the heart more active in distributing the blood throughout the body.

Its greenness is due to its chlorophyll, and it undoubtedly has the manufacturing power in full degree, decomposing carbonic acid and setting oxygen free, under the influence of sunlight.

The blood is sea water, to which has been added hemoglobin as a pigment for carrying oxygen to the cells not in direct contact with the atmosphere, nutrients to take the place of the prey our marine ancestors gobbled up frankly and directly, and white cells to act as the first line of defense.

But some steam is advisable in every gas producer, unless pure oxygen could be used instead of air; or unless some substance like quicklime, which holds its oxygen with less vigor than carbon does, were mixed with the coke and used to maintain the heat necessary for distillation.

"The wine imbibes oxygen, or the acidifying principle, from the air."Id.

Now it is doubtless true that we inhale more oxygen, or at least inhale it less drenched with damp, than the people of Europe, and are, therefore, more emphatically children of fire than they.

Nevertheless I feel that this faculty of jurisprudence still lacks oxygen in the study of criminal law, because its thought is still influenced by the overwhelming authority of the name of Enrico Pessina.

They are then able to obtain oxygen by taking it from the sugar of the juice.

The secret is, that, though the country offers to farmers more oxygen than to anybody in the city, yet not all dwellers in the country are farmers, and even those who are such are suffering from other causes, being usually the very last to receive those lessons of food and clothing and bathing and ventilation which have their origin in cities.

Fishes, though most attractive, must be put in last; for as they are of the highest vitality, so they require the most oxygen and food, and hence should not be trusted until everything in the tank is well a-going.

Plants without light retain their oxygen, which bleaches them.

"When I shut off the oxygen in this second jet," he resumed as if nothing had been said, "you see the torch merely heats the steel.

The greedy lungs of fifty hot-blooded boys suck the oxygen from the air he breathes in his recitation-room.
