SIM – Plate 38a
Plate 38, Fig. 72, 1% Gold chloride and 1% Lead nitrate, equal quantities mixed:This is the best picture in the whole series. The colours are beautiful and also the forms show some of the characteristic qualities. We consider this a really expressive, beautiful Spring picture of Gold chloride and Lead nitrate. Therefore we selected this experiment for our recent publication “Gold and the Sun” (Experiments conducted during the Total Eclipse, 1947) to demonstrate a typical Spring experiment in contradistinction to a typical Mid-Winter experiment.
