*Silver Ores*:—"Silver ores have the colour of conch-shell, camphor, alum, butter, a pigeon, turtle-dove, or the neck of a peacock. They are resplendent as opal (*sasyaka*), agate (*gomedaka*), cane sugar and granulated sugar. They may have also the colour of the flower of kovidara (*Bauhinia variegata*), of lotus. of patalī (*Stereospermum suaveolens*), of kalaya (a kind of *Phaseolus*), of flax. These ores may occur in combination with lead or iron. When roasted they do not split but emit much foam and smoke. The heavier the ores the greater will be the quantity of metal in them." (82)
