M«M III. Attempts to procure the Metals of the alkaline Earths ; and on their Properties. To procure quantities of amalgams sufficient for distil- lation, I combined the methods I had before employed, with those of M. M. Berzelius and Pontin. The earths were slightly moistened, and mixed with one-third of red oxide of mercury, the mixture was placed on a plate of platina, a cavity was made in the upper part of it to receive a globule of mercury, of from fifty to 60 * [From Philosophical Transactions for 1808, vol. 98, pp. 333-370; part reprinted pp. 341-346.] ♦](https://iiif.wellcomecollection.org/image/b21710028_0052.jp2/full/800%2C/0/default.jpg)
