SIM – Plate 35a
Plate 35, Fig. 66, 1% Gold chloride: The original was vividly coloured, but rather dark in appearance. The gold activity has reached to the top and formed a clear dark mauve border, intersected with tiny waves. Underneath the dark border, we notice a narrow band of light purple, and near the middle of the picture traces of golden yellow. Then follows again an irregular dark band which lightens up towards the centre and is followed by a wavy line of bluish purple.
