II. On the production of glycosuria by the effect of oxygenated blood on the liver

Instances of this are not wanting. Magnesium connected with platinum will decompose a magnesium salt, the almost insoluble hydrate of magnesium being found adhering to the negative metal. The deposition of zinc on the plates of an old-fashioned battery, when the battery is pretty well exhausted, is a well-known phe­ nomenon. In our experiments with copper and silver,in conjunction in a solution of nitrate of copper, we never succeeded in reducing the gal­ vanic action to nil by our utmost efforts to exclude all oxygen: and the whole of the present inquiry originated in an experiment described by us before the Physical Society, that mercury and gold in conjunction would decompose mercuric chloride with the deposition not only of the lower chloride, but also of metallic mercury upon the gold. 1875.] Dr. F.
