On this day a fatal duel took place near Exeter, between Sir John Jeffcott and Dr. Hennis. The dispute had arisen, in consequence of the Doctor having been supposed to have uttered words injurious to the reputation of Sir John, a judge of Sierra Leone. On the 26th of July, at the assizes at Exeter, he was charged with having unlawfully, feloniously, and of malice aforethought, inflicted a wound upon Peter Hennis, M.D., with a leaden bullet, of which wound he afterwards died; and Charles Melford, Robert Holland, and George Anthony Halstead, were charged with aiding and assisting him. Sir John Jeffcott had not been apprehended. The other parties this day appeared in court to take their trial; and the following is the substance of the evidence brought forward. John Corfield Irving.—“I had a conversation with Dr. Hennis, on the 10th of May, in consequence of which he wrote a declaration.

The party said they were not true, and that Sir John had acted most honourably. Mr. Melford replied, that the words made use of by Dr. Hennis could not have been mistaken by Mr. Holland; and he showed me the copy of a letter, written by Sir John Jeffcott to Dr. Hennis, on the subject. This is the letter:— “Street’s Clarence Hotel, May 10. “SIR,
