A deputation representative of the whole of the Metropolitan Police force waited on Sir Charles Warren at his private residence yesterday for the purpose of expressing regret at his resignation. The deputation was composed of the superintendents of the various divisions. Superintendent Draper acted as spokesman and expressed the gratitude of the deputation to Sir Charles Warren for the service he had rendered in improving their status and facilitating their work, and also the consideration and equity with which he had treated the force generally. With regard to the men, there were only two points which had given rise to any feeling. One was the new regulations as to drunkenness and the other was the question of pensions for injury received while on duty. Sir Charles thanked the deputation warmly for their assurances of esteem. With regard to the two matters touched upon by Superintendent Draper, he explained that although he had very strong views on the subject of intemperance, he was not responsible for the order which had been recently promulgated. The order emanated from the Home Secretary. On the second point, he (Sir Charles) was equally free from reproach. He had recommended several men on the chief surgeon's certificate for pensions on the ground of injury while on duty, but the Home Secretary had taken a different view of the matter. He assured them that their willing and cordial co-operation in such reforms as he had ventured to propose would be one of the pleasantest recollections of his term of office.

LONDON, THURSDAY

Inquiries made to-day show that sine last night nothing of importance has transpired in connection with the recent murders. At Leman street Police Station this morning there was no one in custody, the men arrested the preceding night having been discharged on their identity being established. At Commercial street two men were detained, but neither of them bore any resemblance to the man of whom the police are now in search. The agitation in regard to the alleged insufficient police protection in Spitalfields is taking a new form, and it is expected that within a few days a deputation from the district will wait upon the Home Secretary. The extraordinary statement of Matthew Packer, the fruiterer, of Berner street, caused some sensation, but, rightly or wrongly, the police are stated to regard it as not of the highest importance. Although investigations are being made in quarters indicated by the informant the police have not yet discovered the two men who, as alleged, had the interview with Packer, and to one of whom the startling statement is attributed. Nothing important is expected to result from the arrest in Old Kent road.

At midnight there were no persons in custody in connection with the recent murders. To-day a man answering to the published description entered a coffee house in Battersea and displayed some hair, apparently human, clotted with blood. He was not detained, but it is stated he left the hair behind him. The police received to-day another letter signed "Jack the Ripper," commencing "Dear Boss," explaining that he always addressed his cousin in those terms, and threatening to perpetrate another murder in the locality on Wednesday next, inflicting injuries similar to those in the last case.
