    * n formed, as it would from the sulphate of lime ; but both the soda and the muriate of lime will be dissolved : then the free alkali will a£t on the muriate of lime which is not supported by an excess of lime, that having been separated by means of the alcohol, and will decompose it almost entirely ; because, independently of its affinity, a given quantity of it requires for saturation a much greater proportion of mu¬ riatic acid than the same quantity of lime : there remains, then, only a small quantity of the muriate of lime, the existence of which may be ascertained by oxalic acid, or by the carbonated alkalis. What-1 have de¬ scribed as happening to the solution by alco¬ hol, takes place during its aCtion. In the foregoing example, I have, stri&ly speaking, only one direCt proof of the decom¬ position of the muriate ; that is, the strongly % characterized odour of the alkali : the other indications of alkalinity might be due to the lime. The solution of a greater quantity of lime might be attributed to the aCtion of the muriate
