[43] Spencer Cowper (1669-1727) was the younger brother of Earl Cowper, who was the first Lord Chancellor of Great Britain. He was educated at Westminster, and made Controller of the Bridge House Estates in 1690. At the time of this trial his brother was the member for Hertford. In 1705 and 1708 he represented Beeralston in Parliament; he was one of the managers in Sacheverell's trial, and lost his seat in consequence, but was afterwards elected for Truro in 1711. In 1714 he became Attorney-General to the Prince of Wales, and in 1717 Chief-Justice of Chester. On the accession of George the Second he was made Attorney-General of the Duchy of Chester, and a Judge of the Common Pleas in 1727. He died the same year. He was the grandfather of William Cowper the poet. [44] Sir Henry Hatsell (1641-1714) was the son of an active Roundhead who sat in the House of Commons during the Commonwealth. He was educated at Exeter College, was called to the Bar in 1667, and became a Baron of the Exchequer in 1697. The present trial was the most conspicuous with which he was connected, from which fact it may be supposed that he never enjoyed a very high reputation. He was removed from the Bench soon after Queen Anne's accession. [45] This John Dimsdale was apparently the father of the first Baron Dimsdale, who inoculated Catharine of Russia and the Grand Duke Paul, her son, for smallpox in 1728. John's father was William, who accompanied William Penn to America in 1684; so that it is not clear who the Mr. Dimsdale, senior, and Dr. Robert Dimsdale of this trial were. The family is, however, one which has long been settled in Hertfordshire. [46] _Vulgar Errors_, Book IV., ch. vi., 'Of Swimming and Floating.'

He studied medicine abroad, and was elected a member of the Royal Society in 1685. In 1687 he went to the West Indies as secretary to the Duke of Albemarle, and made valuable scientific collections. He was elected secretary of the Royal Society in 1693, and succeeded Sir Isaac Newton as president of the same body in 1727. He was physician to Queen Anne and George the Second, and founded the botanical garden at Chelsea for the Society of Apothecaries. He left his collections to the nation, and they formed part of the original nucleus of the British Museum. Sloane Street and Hans Square derive their names from him. [49] The lay reader must observe that Sloane is talking of the 'civil law.'
