Note générale :	This paper is a compilation of representative chemical data, many previously unpublished, for the lake and river waters of the world. The rate of chemical denudation for the continents of the world ranges from 6 long tons per square mile for Australia to 110 long tons per square mile for Europe. The rivers of the world deliver 3.9 billion tons of dissolved material to the sea each year, and the overage concentration of the important constituent in part per million is : bicarbonote 58.4, sulfate 11.2, chloride 7.8, nitrate 1.0, calcium 15.0, magnesium 4.1, sodium 6.3, Potassium, 2.3, iron 0.67, and silica 13.1, for a total of 120 ppm of dissolved solids. The principal gaps in geochimical data for lakes and rivers are long-term downtream overages for the general composition of larges tropical rivers and trace-element analyses for large rivers everywhere.
