After a short overview of the theories on the blue of the sky and water, author turns against Abegg, that, despite the work of Soret (C. r. d. l'Acad. des sciences 69. 1192) and the author's (see Bull. Acad. Royal Belgique [3] 36. 266; C. 99. I. 146), in articles on the color of the seas and lakes (Naturw. Rundsch. 13. 169) their blue color is encountered by two different causes, namely one is attributed to the natural blue coloring of water, and secondly, reflection features. By new experiments concerning the details to the original works it must be referred by author that particles to which the water (distilled or natural) owes its discoloration and the light waves of each length in same way reflected, does not show it therefore a blue color water can arrange. Author sees experiments a new confirmation of its into this previously (previously cited) expressed opinion that the color is compensated to and for itself blue water by in it suspended particles depending upon their nature modified or respectively to the colorlessness.
