Purity of Ice.

Besides the fact that the ice is lighter than water, there is another curious thing about it which persons do not know, perhaps—name’y, its purity. Ice melted always become purely distilled water. Water in freezing turns out of it all that is not water —salt, air, coloring matter and all impurities. Frozen sea water wakes fresh water ice. If yon freeze a basin of indigo water it will make it as pure as that mado*of pure mn water. * When the cold is very sudden these foreign matters have not time to escape, either by rising or sinking, and are thus entangled with the ice, bit do not form any part Qi it.
