Shortly after the discovery of the suicide, we among others visited the cell to see the body, when, in a conversation with the acute and highly intelligent physician to the prison, he observed what iron nerves the murderer must have possessed to effect such a suicide, as from his own height, and the lowness of the latch, he must, in order to complete the strangulation, have persevered for several minutes in keeping his neck strained, during any one of which, up to the last few, he might have readily recovered himself. The body was still stretched on the flags, and exhibited the appearance of a very powerful frame; and when we considered the desperate and utterly fearless mind that had actuated it, it struck us, and others who spoke on the same subject, with more surprise than ever, that M’Gennis should not have been implicated in outrage and bloodshed long before. Such, however, it would appear, was not the case. On being examined at the inquest, the other occupant of that fearful cell denied all knowledge of his brother convict’s intention to commit suicide, or of his having committed it, until morning, stating that he had slept soundly, and heard no noise whatever during the night--a circumstance which seems rather curious, as the cell was but of small dimensions, and M’Gennis must have certainly made some noise, from the manner in which he had perpetrated the horrid deed. On the other hand, it is well known that persons, no matter how restless or uneasy they may have been previously, almost invariably sleep soundly on the night before execution. All doubts and uncertainty are then over: the mental struggle has ceased. Rumours, indeed, were afloat that Cuffe had witnessed the commission of the suicide, and that M’Gennis had urged him to do the like also, in order not to give their enemies and the crowd the gratification of witnessing their execution. But how could this circumstance be known, as Cuffe himself did not admit it? Another rumour was, that M’Gennis’s mother, at parting with him, had instigated him to the terrible act; and this we would be more inclined to give credit to, from what we have heard of her character, as well as from our own observation of her demeanour throughout the trial.
