Interesting to Tea-Drinkers.
If you pour a few drops of strong tea on a piece of iron—a knife blade, for instance—the tannate of iron is formed, which is black. If you mix it with iron-filings or pulverized iron, you may make it a fair article of ink. If you mix it with fresh human blood, it forms, with the iron of the blood, the tannate of iron. Now, when we remember that the liquids which enter the stomach are rapidly absorbed by the veins and absorbents of the stomach, and enter into the circulation, and are thrown out of the system by the skin, respiration, and the kidneys, it is probable that a drink so common as tea, and so abundantly used, will have some effect. Can it be possible that tannin introduced with so much warm liquor, producing perspiration, will have no effect upon the skin? Look at the tea-drinkers of Russia, the Chinese, and the old women of America, who have so long continued in the habit of drinking strong teas—are they not dark colored and leather-skinned? When young they were of fair complexion.—Herald of Health.
