To avoid the errors which are na¬ turally attendant on falfe appearances, a regard fhould be paid to experiments on other waters, and among them to that of Driburg. Much has been faid of its fixed air, but no mention has been made of its enormous quantity of calcarious earth—a moft palpable omifiion—• fince it is known, that the quantity of the one mud annihilate the effects of the other; while the lime, together with a collection of felc- nites, or gypfum, renders the water exceflively hard and heavy to ftomachs that are not of the ftrongeft texture. This fhews the fupe- riority of Pyrmont, to other fources in the produce of that falutary volatile ingredient we call aerial acid, or fixed air. As to the reft of them.
