The man arrested under suspicious circumstances in Belfast on Thursday night was charged at Belfast Police Court yesterday. P.C. Edward Carle, who made the arrest, said the accused would give no further account of himself than that he was the son of a London brewer, that he had an income, and that he had been in Edinburgh, Glasgow, and Greenock. Among articles found upon him were a large clasp knife and chisel, three razors, and a table-knife. Further evidence went to show that the accused, who first gave the name of William John Foster, but afterwards said it was John Foster, had informed the police that he was a watchmaker, but did not work at his trade. The prisoner was remanded for a week. He wore a white turned-down collar marker with a small blood-stain.

The following letter has been received by Mr. Metcalfe, the vestry clerk of Whitechapel, from the Home Office, in reply to a resolution of the vestry asking Mr. Matthews to give every possible facility for the speedy arrest of the murder:--

"Whitehall, October 10."

"Sir,--I am directed by the Secretary of State to acknowledge your letter of the 4th inst., forwarding a copy of a resolution passed at a vestry meeting of the parish of St. Mary, Whitechapel, expressing sorrow at the recent murders in the East End of London, and urging Her Majesty's Government to use their utmost endeavours to discover the criminal. I am instructed to state that Mr. Matthews shares the feeling of the vestry with regard to these murders, and that he has given directions, and that the police have instructions, to exercise any and every power they possess, and even to use an amount of discretion with regard to suspected persons in their efforts to discover the criminal. And I am further to state that the Secretary of State, after personal conference with the Commissioners of Police, at which the whole of the difficulties have been fully discussed, is satisfied that no means has been, or will be spared, in tracing the offender, and bringing him to justice.--I am, sir, yours obediently,

"E. Leigh Pemberton."

It is stated that the police authorities attach a great deal of importance to the spelling of the word "Jews" in the writing on the wall at the spot where the Mitre Square murderer threw away a portion of the murdered woman's apron. The language of the Jews in the East End is a hybrid dialect, known as "Yiddish," and their mode of spelling the word Jews would be "Juwes." This, the police consider a strong indication that the crime was committed by one of the numerous foreigners by whom the East End is infested.

Mr. Edwin Brough, the owner of the hounds Burnaby and Burgho, which are temporarily on "police duty" in London, will next week take Burgho to Brighton for exhibition at the dog show. Both animals will, however, remain in London over Sunday, and Burnaby will be left behind for the use of Sir C. Warren whilst Burgho is at Brighton. Burnaby is the older and better trained dog of the two.
