He died at Bournemouth on the 21st of December 1889, and was succeeded in the episcopate by Westcott, his schoolfellow and lifelong friend.
In Herat, where he spent the greater part of his life, he gained the favour of that famous patron of letters, Mir `Alishir (1440-1501), who served his old schoolfellow, the reigning sultan Husain (who as the last of the Timurides in Persia ascended the throne of Herat in 1468), first as keeper of the seal, afterwards as governor of Jurjan.
After a period of work in Holland he betook himself to England, where his treatise on lettres de cachet had been much admired, being translated into English in 1787, and where he was soon admitted into the best Whig literary and political society of London, through his old schoolfellow Gilbert Elliot, who had now inherited his father's baronetcy and estates, and become a leading Whig member of parliament.
At an early age he entered into a close friendship both with Nizgm-ul-mulk and his schoolfellow IJassan ibn Sabbgh, who founded afterwards the terrible sect of the Assassins.
He declared himself a Tory, attached himself to Harley (afterwards Lord Oxford), then speaker, whom he now addressed as "dear master," and distinguished himself by his eloquence in debate, eclipsing his schoolfellow, Walpole, and gaining an extraordinary ascendancy over the House of Commons.
