"Tea and coffee are the same thing," says Liebig; at least, he says that Theine, the base of tea, and Caffeine, the base of coffee, are the same. What I know is, that, when coffee costs fifty dollars a year, tea costs thirty dollars and eighty-nine cents. For tea and coffee, Hero, allow about another tenth, the cocoa and cream will bring it up to that.
Piperine has also been made by the uniting of piperidine and piperic acid, and, as piperidine has already been formed from pyridine, we have here a true synthesis also. Both theobromine and caffeine, its methyl derivative, have been made from xanthine, which itself can be formed from guanine, a constituent of guano.
So while the thyroid raises the energy level of the brain, and the whole nervous system, as a byproduct of its general awakening effect upon all the cells of the body, the pituitary probably stimulates the brain cells more directly, perhaps in the manner of caffeine or cocaine.
The latter, clad in a grotesquely large and sorry suit of ministerial black, was emaciated and had a pinched bluish countenance. When he saw Baggs he moved forward with a quick uneven step. "Say," he proceeded, "can you let me have something to get a soda- caffeine at a drug store? This ain't a stall; I got a fierce headache. Come out with a dime, will you?
These products are carbon dioxide, formic acid, ammonia, methyl-amine, and sarcosine, the last three being of course in combination with the excess of hydrochloric acid. The artificial preparation of theobromine and caffeine from xanthine, and guanine also show clearly their relations.
These folks usually are and have been so toxic that their bodies had been stashing uneliminated toxins in their fat for years. They are usually so addicted to caffeine, cigarettes, alcohol, and so forth, that when they had fasted, even briefly, their bodies were forced to dip into highly-polluted fat reserves while simultaneously the body begins withdrawal.
The same may be said of chocolate." Playfair and Lankester: Tea contains 3 per cent. theine. Coffee " 1¾ " caffeine. Cocoa " 2 " theobromine. Probably the proportion of caffeine in coffee would be more correctly stated as 1¼ per cent. Dr. Johnson's analysis: Dried milk 35 \ Cocoa essence 34¾ \ Flesh formers in Cocoa-nibs 23 / each hundred parts. Best French chocolates 11 / Mr.
*Caffeine and "Soft" Drinks.*—Recently the practice has sprung up of using caffeine as a constituent of certain drinks supplied at the soda-water fountains.
In a sense, however, caffeine is more deceptive than either alcohol or nicotine, because the usual mode of preparing tea and coffee gives them the appearance of real foods. The housewife who would feel condemned in purchasing caffeine put up as a drug somehow feels justified when she extracts it from plant products in the regular preparation of the meal.
On account of the tannin these beverages tend to retard digestion and to irritate the lining of the stomach—effects that may be largely obviated by methods of preparing tea and coffee which dissolve little of the tannin. In chemical composition caffeine closely resembles a waste, called uric acid, and in the body is converted into this substance.
