The large grenade weighs fourteen or fifteen pounds. It is a canister strongly bound with tarred rope. It is not circular. A number of pistols, swords, cartridges, and bullets, were also found in the room. No person but Thistlewood offered violence before the candles were put out. There were likewise found in the room about three dozen of weapons, which resembled a sort of bayonet. The bottom part had not a socket like a bayonet, but a screw to fasten into a stick. I found also a dozen of sticks, formed for the purpose of being fitted to those bayonets. The bayonets appeared to be newly made. They are very rough, and not at all brightened or polished. The balls I picked up in the room were not fired from pistols. If they had, they would have been flattened; I desired the men to pick the arms up, and each man to keep safely what he found: in consequence, some were in the possession of one man, and some in that of another; two or three muskets were either found in the room, or else taken from some of the persons who had been apprehended. The party had no notice but what I gave that we were officers. The deposition of this witness having been read over to, and signed by, him, JAMES ELLIS was next called.--Having been sworn, he stated, I live at No. 22, Paradise-row, Palmer’s-village, St. Margaret’s, Westminster, and am an officer belonging to the Bow-street patrol. I am also a constable. On Wednesday night last, about half-past seven o’clock, Mr. Stafford, the chief clerk at Bow-street, directed me to take Richard Smithers, John Surman, and William Gibbs, and to proceed in a coach with them to John-street, Edgeware-road, as fast as possible, there to meet Mr. Birnie, who would give us further orders. We did so; and when we arrived at the spot, we found Mr. Birnie waiting. He inquired whether we had seen any thing of the military. We told him we had not. He said he expected them every minute. In about twenty minutes Mr. Birnie called us together. Some inquiries were made, but I don’t know of whom, as to what number were likely to be in the room to which we were going, and whether Arthur Thistlewood was to be there. Mr. Birnie gave me a warrant, signed by Mr. Baker, of Marlborough-street, to apprehend Arthur Thistlewood and thirteen other persons named in it. I have not the warrant; I have given it to Mr. Baker. On our being called together, and Mr. Birnie being given to understand that Thistlewood and others were in the room, he asked how many there might be present, and was informed that there was about a dozen. He then inquired how many there were of us. We told him about a dozen also. He said he had been disappointed in the soldiers, who had perhaps missed their way, and were half an hour too late, and that we must proceed to apprehend the parties. We said we would do the best we could. Smithers observed, if there were forty of them we would secure them. Mr. Birnie then directed me to call Ruthven, another officer, out of the Horse
