    tb mlfreprefentatlon of the fenfcj a paffage that occurs here merits fome notice. ^ I have given ^ table to fhew the fuhbrdination of the powers of bodies, of oppofite genera^ with refpeft to each other. This table is formed only in that view^ to fhew the relation the refpedlive fpecies of thofe two capital genera of bodies, called acids and alkalies, have, with regard to their fubordination of attradlion, or their power of departure, or difpoffeffion of each other, from any third body of the oppofite genus; and not to diftinguifh which, through the whole fpecies of each genus, will aft on any particulars of thofe of the oppolite. But, in order to render the table defeftive, or faulty, they have confounded the difpofition, or want of difpolition to attraft each other at all, with the comparative degree of force or power of fuch attraftion, which any two may have with refpeft to a third : and as in- ftances of my miftaking the degrees of attraftion, have offered thofe fpecies,which have attraftions with refpeft to certain others, againft thofe that have none, with refpeft to the fame : as in the cafe of lead and mercury with the vitriolic acid, and feveral more. Whereas^ there can be no comparifon of the degrees of fubordination of attraftion, or power of difpoffeflion, with re¬ gard to a third body, betwixt two others; of which the one will not at all combine with, or attraft fuch third. The fafts themfelves like- wife brought here, refpefting thefe attraftions, are moft of them falfe, even conlidered in any light: as we fhall have occafion to fee in fome B inflances
