Note 20 — INTRODUCTORY NOTE TO CHAPTER I

William, Lord Cavendish, grandson of George Augustus Henry, first Earl of Burlington, and great-grandson of the fourth Duke of Devonshire. In 1858 he became the seventh Duke, and died in 1891. He married in 1829 Blanche Georgiana, daughter of the sixth Earl of Carlisle. He was beloved and respected by all who were privileged to know him. In the spheres of education and science his quiet activities were not unremarked. He was an admirable landlord and a most efficient man of affairs. For his careful education of his eldest son, the Marquess of Hartington, the nation owes him a large debt of gratitude.
