I was aware that some one, apparently at a vast distance, was calling me by my Christian name. [...] In the short space it took to cover the road between the path from Hamilton's shop and the first plank of the Combermere Bridge I had thought over half-a-dozen people who might have committed such a solecism, and had eventually decided that it must have been some singing in my ears.
