I am come to send fire on the earth; and what will I, if it be already kindled?
I remember, some years ago, when I was at Shields, I went into a glass-house; and, standing very attentive, I saw several masses of burning glass of various forms. The workman took a piece of glass and put it into one furnace, then he put it into a second, and then into a third. I said to him, "Why do you put it through so many fires?" He answered, "Oh, sir, the first was not hot enough, nor the second; therefore we put it into a third, and that will make it transparent."
