Abstract
A QUANTITATIVE account of oceanic palæochemistry depends largely on the theory accepted for the origin of the ocean, especially for its halogen content. Yet with any tenable view, useful limits for biological consideration can be established for such quantities as the total salinity at the beginning of the Cambrian period. The K/Na ratio of the original ocean can also be stated with some confidence, when we consider that the mean composition of igneous rock has not appreciably changed over the oceanic age.
