Predisposing affinity, the existence of which at first consideration it is difficult to admit, may be easily accounted for by supposing the attractions of the simple principles of compound substances. And this doctrine will apply in all instances where the constitution of bodies is known. Predisposing affinity ought not to be considered as the affinity of non-existing bodies for each other; but as the mutual affinity of their simple principles, disposing them to assume new arrangements.
