ABSTRACT
Fittag, R. We are now forced to increase the number of compounds, not merely in order to prepare new substances, but to discover natural laws.
Proust, J.L. We must recognize an invisible hand which holds the balance in the formation of compounds. A compound is a substance to which Nature assigns fixed ratios, it is, in short, a beingwhich Nature never creates other than balance in hand, pondere et mensurd.
