If you put a piece of potassium in contact with the water, the latter will at once decompose, the potassium absorbing the oxygen, and setting free the hydrogen as gas, which you could collect and ignite with a match, when you would find it would burn. That hydrogen was the hydrogen forming part of your cotton, silk, or wool, as the case might be. We must now attack the question of sulphur.
The gelatinous tissues, the gelatine of the bones, the membranes, the cells and the skin suffer, in the animal body, under the influence of oxygen and moisture, a progressive alteration; a part of these tissues is separated, and must be restored from the blood; but this alteration and restoration are obviously confined within very narrow limits.
But add a touch of chemistry, and he was interested. Chemistry leads up to life. He said he did not think he would feel threatened or insulted if a chemist should take his protoplasm, or mix his hydrogen, oxygen, and carbon, and make an animalcule incontestably swimming and jumping before his eyes. It would be only evidence of a new degree of power over matter which man had attained to.
The more or less cramped attitude of the chest in sewing makes it especially necessary that the lungs should be well supplied with oxygen, else the blood will lose vitality, the appetite will go and the nerves will be straining to bring the muscles up to work which they could do quite easily if they were receiving the right amount of nourishment from air and food.
Many there are, who sleep with their heads covered; this is highly destructive to health, and cases of scrofula may be directly traced to this custom. The poisonous exhalations from the body, together with the constant exhaustion of the oxygen from breathing, renders this confined air foul to the last degree.
To-day the winter has somehow got into my bones or up in my head, and I feel as light-hearted and reckless as if I had been having oxygen pumped into me by a special contrivance; so plainly this is the proper time for my scarlet skirt." "It is so funny that scarlet suits you so well, for you are certainly not a brunette," Mrs. Burton said, looking at Katherine in warm sisterly admiration.
Without thinking, we work the muscles to draw up the ribs about eighteen times every minute, because all parts of the body are calling for oxygen. The harder we work the oftener we breathe because the muscles need more oxygen to make them go. =Why we should breathe through the Nose.= Most persons find it easy to breathe through the nose.
I suppose you will reply, By combining with oxygen and forming humic acid. But would not the theory of the decomposition of carbon do quite as well?
They are born with the organs I cannot tell how or why, but heredity explains all that, and having once got the organs, the objects that come into contact with them in daily life naturally produce the same effect as on the parents, just as oxygen coming into contact with the right quantity of hydrogen will make water; hence even the first time the offspring come into contact with any given object they act as their parents did."
The surgeon told The Spider that they were using oxygen, which fact in itself was significant. The Spider crossed the street to a restaurant, drank several cups of coffee, and on his way out bought a supply of cigars. He played solitaire in his room all that afternoon, smoking and muttering to himself until the fading light caused him to glance at his watch.
