This is the process of assimilation of carbon from the carbon dioxide of the air. If we leave aside the change in the chemical combination which the carbon undergoes, there remains the picture of the plant drawing this matter to itself from its environment and at the same time subjecting it to a spatial condensation.
But, to be perfectly clear, I will say that there are live things that must, above all others, be looked after in tunnel work: the air pressure, the amount of carbon dioxide in the air, the length of the shifts which the men work, the state of health of the men as near as physical examination can determine it, and the rapidity with which the men come out of the air, so as to prevent carelessness which may cause the bends.
They load up with oxygen in the lungs and carry it to all parts of the body. Here they trade it off for carbon dioxide, a waste substance. This they carry back to the lungs to be cast out of the body. There is one white blood cell to every four hundred red ones. The white cells are the body-guards. They change their shape and are able to crawl through the walls of the capillaries.
Good results are also reported from the application of carbon dioxide snow, especially when this follows upon a course of X-ray treatment. #Melanotic Cancer.# Under this head are included all new growths which contain an excess of melanin pigment. Many of these were formerly described as melanotic sarcoma. They nearly always originate in a pigmented mole which has been subjected to irritation.
=How the Blood trades Waste for Oxygen in the Lungs.= The blood, which is constantly running from all parts of the body to the lungs, collects waste formed from the burnt food and dying parts of the organs. When the blood comes to the lungs, it is full of this waste, called carbon dioxide. The blood tubes divide into fine branches with very thin walls and form a rich network over the air sacs.
Certainly, there is nothing strange to us in his describing carbon dioxide gas as being 'finer than vapour and denser than air'; but why did he call this a 'paradox'? What prevented him from ranking it side by side with air?
I mean that For one thing, the temperature would be too harsh. It's way too cold on Mars to support life. Not to mention the atmosphere, which is mostly carbon dioxide." "Oh, my dear boy," smiled the face. "You don't know anything, do you?
Cl :MnO = 71:86.9. After canceling the common factors, there remains 2Na S O :MnO = 316.4:86.9, and the factor for the conversion of thiosulphate into an equivalent of manganese dioxide is 86.9/316.4.
By far the most general and important effect arising from the decay of organic matter in the earth is to be found in the carbon dioxide which is formed as the oxygen of the air combines with the carbon which all organic material contains.
But that last part ought to be easy, for I think I can alter my warfare bomb-dropping attachment to serve the purpose. "What I really need, however, is some new chemical combination that will quickly put a really big blaze out of business. There are any number of these chemicals, but most of them depend on the production of carbon dioxide.
