Abstract
§ 185 (a). Here we use silver solution (§ 94), or dissolved sugar of lead (§ 125 (a)), which is dripped into the water. If it does not become cloudy here, then it is pure and free from foreign substances. We never find wells, and seldom springs, in which the water does not change with sugar of lead, but sometimes lakes [have water that does not change with sugar of lead]. A very pure water becomes yellowish with blauholtz [word of German origin, meaning logwood].
