"Well, then, get two," was the reply.
Cavendish extended his eccentric reception to his own family. His heir, Lord George Cavendish, visited him once a-year, and was allowed an audience of but half-an-hour. His great income was allowed to accumulate without attention. The bankers where he kept his account, finding they had in hand a balance of 80,000l., apprised him of the same. The messenger was announced, and Cavendish, in great agitation, desired him to be sent up; and, as he entered the room, the ruffled philosopher cried, "What do you come here for! what do you want with me?"
"Sir, I thought it proper to wait upon you, as we have a very large balance in hand of yours, and we wish your orders respecting it."
"If it is any trouble to you, I will take it out of your hands. Do not come here to plague me!"
"Not the least trouble to us, sir, not the least; but we thought you might like some of it to be invested."
"Well, well, what do you want to do?"
"Perhaps you would like 40,000l. invested."
"Do so, do so! and don't come here to trouble me, or I'll remove it," was the churlish finale of the interview.
Cavendish died in 1810, at the age of seventy-eight. He was then the largest holder of Bank-stock in England. He owned 1,157,000l. in different public funds; he had besides, freehold property of 8,000l. a-year, and a balance of 50,000l. at his bankers. He was long a member of the Royal Society Club, and it was reported at his death that he had left a thumping legacy to Lord Bessborough, in gratitude for his Lordship's piquant conversation at the club meetings; but no such reason can be found in the will lodged at Doctors' Commons. Therein, Cavendish names three of his club-mates—namely, Alexander Dalrymple to receive 5,000l., Dr. Hunter 5,000l., and Sir Charles Blagden (coadjutor in the water question) 15,000l. After certain other bequests, the will proceeds: "The remainder of the funds (nearly 100,000l.) to be divided: one-sixth to the Earl of Bessborough," while Lord George Henry Cavendish had two-sixths instead of one. "It is, therefore," says Admiral Smyth, in his History of the Royal Society Club, "patent that the money thus passed over from uncle to nephew was a mere consequence of relationship, and not at all owing to any flowers or powers of conversation at the Royal Society Club."
Cavendish never changed the fashion or cut of his dress, so that his appearance in 1810, in a costume of sixty years previously, was odd, and drew upon him the notice which he so much disliked. His complexion was fair, his temperament nervous, and his voice squeaking. The only portrait that exists of him was sketched without his knowledge. Dr. George Wilson, who has left a clever memoir of Cavendish, says: "An intellectual head, thinking—a pair of wonderful acute eyes, observing—a pair of very skilful hands, experimenting or recording, are all that I realize in reading his memorials."
