Show A SIMPLE WATER TEST. Into a perfectly clean bottle having a stopper of ground glass put five ounces of the water to be tested. To the water add ten grains 9by weight0 of pure granulated white sugar. Cork tight and set in a window exposed freely to light, but not to the direct rays of the sun. Do not disturb the bottle and keep the temperature as near 70 degs.[degrees] Fahrenheit as possible. If the water contains organic matter, within forty-eight hours an abundance of whitish specks will be seen floating about, and the more organic matter the more specks. In a week or ten days, if the water is very bad, the odor of rancid butter will be noticed on removing the stopper. The little specks will settle to the bottom, where they will appear as white, flaky masses. Such water should not be used for drinking purposes, according to health authorities recommending the foregoing simple test. |
