This was but a vain boast; for, at the moment the officer seized him, he was evidently paralized. He shewed no disposition to resist. No arms were found in the room, with which he could defend himself, and when he was carried off to Bow-street, six officers were left behind to search every hole and corner in the house. This they did, and found nothing to warrant an opinion that he was capable of making a formidable resistance.

It is, however, rather a suspicious circumstance, that while the officers were engaged in securing their prisoner, the landlady, Mrs. Harris, slipped out, and gave an intimation of what was occurring to her husband, who was a type-founder in the manufactory of Messrs. Caslon. From that time he has been “out of the way.” It was ascertained that he was the manufacturer of all the bullets found upon the conspirators. A warrant was issued for his apprehension.

The officers are satisfied that the arms which Thistlewood had in Cato-street have not been found, and imagine that he deposited them with some friend. It is a matter of surprise, that in getting rid of these evidences of his guilt, he should have kept in his possession the black belt which was seen round his waist in the loft, and which, with some ball cartridges, was found in his pocket in White-street.

Up to the time of his last appearance before the Privy-Council, he made no inquiries respecting his family, but was particular in his questions as to the persons who had been arrested. Among others, he mentioned the name of Palin, for whose apprehension a reward of two hundred pounds had been offered, and again describing in the most minute manner the person of Brunt, with an evident intention to avoid mentioning his name, he asked if he was arrested? Upon these heads he received no satisfactory answer.

Mrs. Thistlewood is a smart, genteel little woman, dresses well, and from the first seemed perfectly alive to the situation of her husband, in whose political sentiments she heartily concurs. On the officers going to search her lodgings, she did not manifest any of that alarm which, in a female, might be considered natural. She received them with calmness, accompanied by a certain air of dignity, and demanded their authority for searching her premises. Being satisfied on this head, she permitted the search to be made without further hindrance. She has a son, who seems a genteel ingenious youth. When she obtained permission to visit her husband, the interview always took place in the presence of an officer, and her person was scrupulously searched, even to the removal of her stays and cap, and these precautions were continued from first to last.

The prisoners all standing fully committed on the clearest and most satisfactory evidence, the preparations for their trial commenced, and on the 8th of March the following Special Commission of Oyer and Terminer was issued by the Crown:—

George the Fourth, by the grace of God, of the united kingdom of Great Britain and Ireland, King, defender of the Faith, to our most dear cousin, William Henry Duke of Portland; our well-beloved and faithful Councillors, Sir Charles Abbott, knight, Chief-Justice, assigned to hold Pleas before us; Sir Robert Dallas, knight, Chief-Justice of our Court of Common Pleas; Sir Richard Richards, knight, Chief-Baron of our Court of Exchequer; our beloved and faithful Sir William Garrow, knight, one of the Barons of our said Court of Exchequer; Sir William Draper Best, knight, one of the Justices assigned to hold Pleas before us; Sir John Richardson, knight, one of the Justices of our said Court of Common Pleas; Sir John Silvester, baronet; Newman Knowlys, Francis Const, Charles Bosanquet, Charles Trelawny Brereton, James Clitherow, James Ferguson, Edmond Alexander Howard, Richard Paul Joddrell, Samuel Purkis, Thomas Wood, and Peregrine Dealtry, Esqrs., greeting.
