Destruction of Germs in Water.

The sterilizing of water is cusily accomplished by keeping it at or near the boiling point for fifteen minuets; five minutes beat is sufficient to destroy all harmful micro-organisms; still less time suffices to destroy the disoase-produclng \ urietios which are recognized as liable to occur in water. Thus, merely raising to the boiling point a clear water containing the micro-organisms of malarial disorders,typhoid, cholera, diphtheria, or of suppurative processes, and allowing it to gradually cool, iusuros the destruction of these germs; they are also destroyed by keeping the water for from a quarter to half an hour ut a teniperaturo of 170 degrees F., though occasionally very resistant but harmless bacteria may get into water. The brief heating, however, renders them safe for drinking purposes; but when it is desired to destroy every micro-organism that may be present in a contaminated water, it is to bo heuted for one hour, and allowed to cool s'owly, whon it may be used for cleansing wounds or for alkaloidal solutions.—[Boston Cultivator.
