SIM – Plate 34a
Plate 34, Fig. 64, 1% Gold chloride and 1% Copper sulphate, equal quantities mixed : This we would term a specially insignificant, expressionless picture of gold chloride and copper sulphate, which is seldom obtained. Even the colours do not look very bright. Most of the picture is dark purple, contrasting with the top band of light bluish purple, followed by a band of light yellow and a scarcely noticeable border line of pale green. This is a disappointing result.
