EMERALD-GREEN:  ITS PROPERTIES AND MANUFACTURE.[1]

[Footnote 1:  This substance is also known by the name Schweinfurt green.]

By Robert Galloway, M.R.I.A.

The poisonous effects of wall-paper stained with emerald-green (aceto-arsenite of copper) appears to be a very favorite topic in many journals; it is continually reappearing in one form or another in different publications, especially medical ones; there has recently appeared a short reference to it under the title, “The Poisonous Effect of Wall-paper.”  As some years ago I became practically acquainted with its properties and manufacture, a few observations on these subjects may not be without interest.
