I took the stuff to Thorold, and Thorold had the exquisite agony of discovering two new elements in what was then a confidential analysis. He has christened them and published since, but at the time Gordon-Nasmyth wouldn't hear for a moment of our publication of any facts at all; indeed, he flew into a violent passion and abused me mercilessly even for showing the stuff to Thorold. "I thought you were going to analyse it yourself," he said with the touching persuasion of the layman that a scientific man knows and practises all the sciences.
I made some commercial enquiries, and there seemed even then much truth in Gordon-Nasmyth's estimate of the value of the stuff. It was before the days of Capern's discovery of the value of canadium and his use of it in the Capern filament, but the cerium and thorium alone were worth the money he extracted for the gas-mantles then in vogue. There were, however, doubts. Indeed, there were numerous doubts. What were the limits of the gas-mantle trade? How much thorium, not to speak of cerium, could they take at a maximum. Suppose that quantity was high enough to justify our ship-load, came doubts in another quarter. Were the heaps up to sample? Were they as big as he said? Was Gordon-Nasmyth—imaginative? And if these values held, could we after all get the stuff? It wasn't ours. It was on forbidden ground. You see, there were doubts of every grade and class in the way of this adventure.
We went some way, nevertheless, in the discussion of his project, though I think we tried his patience. Then suddenly he vanished from London, and I saw no more of him for a year and a half.
My uncle said that was what he had expected, and
