LONDON, WEDNESDAY, SEPT. 7, 1864.  " Truth is stranger than fiction" has long been a recognised saying, and certainly those who analyse the striking events of life will see much reason to ratify the force of the observation. The news that yesterday circulated through the metropolis of the cepture of MULLER was a remarkable piece of intelligence. Had such an incident been introduced into the pages of fiction it would have been doubtless regarded with derision, and we can fancy the captions critic or matter-of-fact reader declaring that authors were getting quite beyond the bounds of probability in their extravagant assertions. It has been reserved for us, however, to witness in real life as strange a tale as any that fancy could devise, or the sharpest wit develop in a sensational work. There have been many curious incidents connected with the murders that have startled our generation from its propriety, but not one has sur► passed, while few have equalled, the peculiar characteristics of this case. A dense and seemingly impenetrable mystery Lung over the affair at first but the clouds seemed to clear away as if by magic, and the successive proofs accumulated, until at last from the Atlantic came the tidings that the murderer has been captured. There is nothing astonishing in the report that MULLER denies his guilt, for, judging from the circumstances of the case, he is just the man to do it. The intelligence conveyed in the telegram that "the hat and watch of Mr BRIGGS were found in the possession of the prisoner'' seem to ho conclusive evidence, and to furnish testimony that nothing can dispute or gainsay. What could have been the motive for MULLER'S retaining the watch it ie indeed difficult to conceive. He had far better have destroyed it or got rid of it in some fashion. The hat is a strange coincidence and a startling confirmation of the adage that Murder will out." It is not likely that during this lapse of time Munnett should not have ascertained that the hat was not his own, and thence the natural inference would have been to get rid of such a possession that could furnish such a damnatory proof against him. It would seem as if the unhappy man had been under a .delusion that he was perfectly safe, and that there was no probability of his being in any way suspected. No other explanation can be given of the fast that he has gone about his work in about as senseless a fashion as can well be imagined. Perhaps part of the surprise that nas turaily is experienced at these affairs, arises from it being generally presupposed that murderers and the worst class of robbers are men of great ability in their vocation. such is not ordinarily the case, although there have been signal proofs to the contrary, which have formed the groundwork of the notion. We may notice in perusing the annals of crime that the most eltraordinary mistakes have been made, and that the murderer of Mr. BRIGGS has been kept in countenance in his most extrava gent blunders by others of the dark race of crime  who have gone before him. It would be almost impossible for the greatest adept in crime to encom• pass all the dangers and difficulties that are hedgtd round his path, and it is a satisfactory conclusion to arrive at, that there is little chance of a murderer  escaping conviction now•a-days. It must appear probab'e to all who have thought upon the subject, that MULLER must have had some secret motive in his mind that we cannot fathom. It is not in ac. cordance with the evidence of common sense that a man should incur such frightful risks to put himself in possession of the trifles that he secured. A watch, however valuable, is a dangerous property to an unrightful possessor. It must have hee.o most likely one of two motives that led to the perpetration of the fearful crime. Either the prisoner bey lieved that Mr. BRIGGS had a considerable sum about him, or else he was fulfilling a project of vengeance. The mystery which enshrouds the whole affair may be greatly cleami np at the  approaching trial, but the most important event has already taken place in the capture of the criminal. The American authorities will, no doubt, affordevery facility for the delivery of the culprit, and there is no reason to doubt that justice will be satisfied, and that a foul crime will be expiated in the most effective form which human laws can devise; It is not likely that in this ease there wi;i tithe toe hosts of well meaning
