On March 4th, 1830, I arrived in London, where a new world seemed opened to me.
I had an immense advantage over many others dealing with the problem inasmuch as I had no fixed ideas derived from long-established practice to control and bias my mind, and did not suffer from the general belief that whatever is, is right.
It is true I had been successful on a small scale in overcoming one of the main difficulties in the new process, but there was still much to invent, and much that at that period I necessarily knew nothing about.
We fixed on No. 4, Queen Street Place, for our City offices, and it was from there that so many of my patented inventions were dated.
I was quite unable to make any white metal alloy hard enough to be made into powder by my machinery.
