Note 40 — Chapter XII · SODIUM
George Kamensky translation
Alloys are so similar to solutions (exhibiting such complete parallelism in properties) that they are included in the same class of so-called indefinite compounds. But in alloys, as substances passing from the liquid to the solid state, it is easier to discover the formation of definite chemical compounds. Besides the alloys of Na with Hg, those with tin (Bailey 1892 found Na2Sn), lead (NaPb), bismuth (Na3Bi), &c. (Joannis 1892 and others) have been investigated.
