Sir Walter Scott's "Letters on Demonology and Witchcraft" were his contribution to a series of books, published by John Murray, which appeared between the years 1829 and 1847, and formed a collection of eighty volumes known as "Murray's Family Library."
In these "Letters upon Demonology and Witchcraft," addressed to his son-in-law, written under the first grasp of death, the old kindliness and good sense, joined to the old charm in story-telling, stand firm yet against every assault; and even in the decay that followed, when the powers were broken of the mind that had breathed, and is still breathing, its own health into the minds of tens of thousands of his countrymen, nothing could break the fine spirit of love and honour that was in him. When the end was very near, and the son-in-law to whom these Letters were addressed found him one morning entirely himself, though in the last extreme of feebleness: his eye was clear and calm—every trace of the wild fire of delirium was extinguished: "Lockhart," he said, "I may have but a minute to speak to you. My dear, be a good man—be virtuous, be religious—be a good man. Nothing else will give you any comfort when you come to lie here."
