Analyzing Waters.

Mineral waters are easily analyzed by means of the spectroscope, as shown by M. Jacques Bardet, and this is likely to prove one of the best methods for this work. He sends a beam -of x light through the water to be analyzed and thence through the spectroscope prism, in order to permit of examining the spectrum, this method revealing very minute traces of metals. He finds the most varied metals in different samples of mineral water, and even the rarest metals, such as germanium and gallium, "which are very rarely foimd in nature.”
