Well, first of all, my hand went queer. It was a sort of dead, numb feeling, spreading into the arm above the wrist, and I was scared, I can tell you. I was almost certain that these were new rays, and I hadn't the least notion what effect they might have on living tissue. The numbness kept on all day, with a sort of tingling in the finger-tips, and I went to bed in a bit of a panic. And when I woke, the radium burn had quite gone, leaving a little scar behind, and the cut had begun to heal. It was very nearly healed!"
