The sensation caused by the late mysterious entrance of the boy Jones into Buckingham Palace, appears to be even greater than that produced by his apprehension in the same place in December, 1838. The object which prompted so daring a proceeding is still involved in the utmost doubt; but it was not probable that it was his intention to do any personal injury to her Majesty, for had such been his purpose abundant opportunities of carrying it into effect presented themselves during his concealment in the chamber where he was secured. From a well informed source, we have heard the sofa under which Jones was found is in the ante-room in which the Princess Royal and Mrs. Lilley, her Royal Highness’s nurse, repose. On the night in question the latter had not long retired to rest ere she fancied she heard a noise similar to that likely to be caused by a person who was endeavouring to prevent his presence from being discovered, and was moving in a stealthy manner. Mrs. Lilley at first treated the matter as of no moment, thinking probably that the noise might have been imaginary. Its renewal, however, created an alarm, and she instantly summoned those of the attendants who were on guard in the adjoining ante-chamber. On their arrival the offender was quickly discovered and drawn from his place of hiding. The statement then goes on to say that her Majesty, who but three hours previously had been sitting on this particular sofa, having been disturbed by the confusion to which the event had given rise, called out and desired to be informed as to its cause. As an apprehension was, however, entertained that the sudden communication of the occurrence might be attended with an unfavourable effect on her Majesty, the attendants gave an evasive answer. The Queen repeated her command, and then the fact of the boy’s concealment and subsequent apprehension were made known to her. The circumstances at that time appeared not to produce any very visible effect on her Majesty, but on Thursday symptoms of other than a satisfactory character were apparent. It affords us the highest gratification to be able to add that a few hours of quietude tended to the restoration of her Majesty.
