Summary
[Bibliographical Note.—The Papers collected in this section appeared originally in magazines or other publications, as noted under each of them. The first six were reprinted in On the Old Road, eds. 1885, 1899; the seventh was reprinted in Arrows of the Chace, ed. 1880. A few errors in the former reprints are noted further on. For introductory notes on these Natural History papers, see above, pp. xxxi., xlv.]
ENQUIRIES ON THE CAUSES OF THE COLOUR OF THE WATER OF THE RHINE
I Do not think the causes of the colour of transparent water have been sufficiently ascertained. I do not mean that effect of colour which is simply optical, as the colour of the sea, which is regulated by the sky above or the state of the atmosphere, but I mean the settled colour of transparent water, which has, when analysed, been found pure. Now, copper will tinge water green, and that very strongly; but water thus impregnated will not be transparent, and will deposit the copper it holds in solution upon any piece of iron which may be thrown into it. There is a lake in a defile on the northwest flank of Snowdon, which is supplied by a stream which previously passes over several veins of copper; this lake is, of course, of a bright verdigrise green, but it is not transparent.
