    that it is only extricated by fire, . as other matters are from compound bodies. Induc¬ tions, that fire fevers bodies, but neither creates nor deflroys matter, Obfervations and experiments, {hewing that all the alkaline fubftances of the che- mills, are compound bodies. And that the cauflic volatile alkali is that which is leaft compounded. Experiments, fhewing the alkaline matter folitary, and demonflrating this to be an elementary matter, altho* not hitherto known or noticed as fuch, and that there is but.one elementary alkali, Obfervations and experiments, fhewing that the atoms of alkaline element repel each other *, and fhewing the ratio of this repulfion at given difiances, and that by reafon of this repulfion varied by diflance, this element is an elaflic, compreflible, ex- panfible, invifible fluid. Experiments fhewing the atomary repuE lion of this element, counterpoiled by the attraction of other matter, and the forma¬ tion of fluids of greater denfity or lefs vo¬ lume, but yet invifible : And next, the a- tomary repulfion of alkaline element over¬ powered by the attra&ion of other matter to its atoms, which are thus approximated fuf- ficiently
