V.—On the expansion of water

Abstract

ON re-determining the co-efficient9 of expansion of water, they were found not to agree with Kopp's, and as his are results generally used by chemists, it may not be here out of place to give the new values.

Bunsen's Batteries and the Electric Arc

“…He noted the importance of correct current density, and deposited manganese in a similar way. Under Bunsen's guidance, the isolation of calcium was achieved by Augustus Matthiessen (1831-1870) (28,29). He electrolyzed a fused mixture of CaCl2, SrCl2, and a little NH4CI, between a cylindrical iron anode and, separated by a small porous pot, a pointed wire cathode.…”
