The day after that-all this was in June of '82-the professors had trooped out again in a great excitement. As they passed Ammi's they told him what queer things the specimen had done, and how it had faded wholly away when they put it in a glass beaker. The beaker had gone, too, and the wise men talked of the strange stone's affinity for silicon. It had acted quite unbelievably in that well-ordered laboratory; doing nothing at all and showing no occluded gases when heated on charcoal, being wholly negative in the borax bead, and soon proving itself absolutely non-volatile at any producible temperature, including that of the oxy-hydrogen blowpipe. On an anvil it appeared highly malleable, and in the dark its luminosity was very marked.
