We know with scientific certainty that the difference between a diamond and a piece of charcoal, or between a pearl and an oyster-shell, is the way that the particles of carbon in the one case, and of calcium carbide in the other, are arranged.
Many patients who are ill lose their calcium, and they may not receive a sufficient amount of it unless milk is given them. Even if such patients are taking milk, the heart and the whole general condition sometimes such; to improve when calcium is added to the diet. It may be given either in the form of lime water, calcium lactate or calcium glycerophosphate.
This renders the situation more simple as any carbonate, hydrate or oxide of lime will accomplish these purposes. Composition. The first consideration is the actual content of calcium and magnesium. A guaranteed analysis is the only safe basis of purchase.
This is found in all the tissues and fluids, and is one of the most important inorganic salts the body contains. It is absolutely necessary for continued existence. By a combination of phosphorus with sodium, potassium, calcium, and magnesium, the various phosphates are formed. The phosphates of lime and soda are the most abundant of the salts of the body.
Molasses is quite rich in calcium, one tablespoonful yielding as much as five ounces of milk, and is for this reason a better sweet for growing children than ordinary sugar or corn syrup when the amount of milk which they can have is limited, or when fruits and vegetables are hard to get.
Far stronger solutions of ammonium chloride can be nitrified than of ammonium carbonate, if the solution of the former salt is supplied with calcium carbonate. Nitrification has in fact commenced in chloride of ammonium solutions containing more than two grammes of nitrogen per liter.
"But I thought you had analyzed this soil," was the reply. "Oh, I only tested for limestone and acidity," explained Percy. "I wish to have exact determinations made of the nitrogen and phosphorus, and perhaps of the potassium, magnesium, and calcium.
Here are some from the official list of 1899; Dynamite, Railways, Spirits, Iron, Sugar, Wool, Bricks, Earthenware, Paper, Candles, Soap, Calcium Carbide, Oil, Matches, Cocoa, Bottles, Jam, &c. A large loan had been constantly talked of throughout the year, but no one knew for what purpose it could be required.
Then in order of their weight come carbon, hydrogen, nitrogen, calcium, phosphorus, sulphur, sodium, chlorine, fluorine, potassium, iron, magnesium and silicon. Because it will be helpful in giving a better idea of the necessity for proper feeding, I shall devote a few words to each of these elements.
It is only necessary to keep in mind the fact that the ending -ate on the common chemical names signifies the presence of oxygen Thus calcium carbonate is composed of the three primary elements, calcium, carbon and oxygen. "Of course the chemical element is the simplest form of matter.
