"A story was told me by the late Earl Grey relating to himself and Mr. Burke. Lord Grey told me that on one occasion when in the House of Commons, as Mr. Grey, he had been speaking with considerable force of language and greater vehemence of tone than some persons might have thought seemly. On resuming his seat, he said to Mr. Burke, “I hope I have not shown much temper.” “Temper!” replied Mr. Burke, “temper, sir, is the state of mind suited to the occasion!”"
