Reichardt, professor of chemistry in the university of Jena, Germany, contributes some interesting observations on the question of that the water was of only moderate hardness. Professor Reichardt also experimented with alength of common lead pipe holding about onequart of water, testing it alternately with springwater, distilled water, and water charged withcarbonic acid, and allowing the water to standin each case for varying periods of time. Thelatter two kinds of water showed at once somereaction on lead, while the harder spring waterdid not have any chemical effect, the air beingexcluded in all cases. When the pipe was alter-nately filled and emptied, he found the met-al readily attacked by the water. Hence Pro-fessor Reichardt argues that lead pipes are un-. « ? /3DESiGf-
