It is not possible to suppose that Mr. D'Israeli could pass this calmly by; and he did not, but wrote to O'Connell's son as follows:-- "31A, Park Street, Grosvenor Square, "Tuesday, May 5. "Sir, "As you have established yourself as the champion of your father, I have the honour to request your notice to a very scurrilous attack which your father has made upon my conduct and character. "Had Mr. O'Connell, according to the practice observed among gentlemen, appealed to me respecting the accuracy of the reported expressions, before he indulged in offensive comments upon them, he would, if he can be influenced by a sense of justice, have felt that such comments were unnecessary.
