A drowned animal will, in general, be recovered more slowly and with greater difficulty than one which has fallen into a state of asphyxia from strangulation. It is probable that, in the former case, the sudden reduction of temperature will contribute to the more rapid extinction of vitality. Having thus examined the pretensions to which the several modes of restoring animation are entitled, we may conveniently introduce in this place some observations upon the different methods which have been adopted to secure condemned criminals against the fatal effects of their execution. There can be no doubt but that by making an opening in the trachea, below the ligature, death might in some cases be prevented, provided the neck were not dislocated, nor the weight of the body very considerable. _Richerand_ says, that a surgeon of the imperial armies, whose veracity cannot be questioned, assured him that he had saved the life of a soldier by performing the operation of laryngotomy some hours before he was executed. Dr. _Male_[71] states that it was tried on one _Gordon_, a butcher, who was executed at the Old Bailey in the early part of the last century; the body having hung the usual time, was removed to a neighbouring house, where a surgeon waited to receive it, and enforce every means calculated to restore animation: he opened his eyes, and sighed, but soon expired: the want of success was attributed to his great weight, but we apprehend that, if the statement be correct as to his opening his eyes and sighing, the failure must have depended upon want of skill in the operators. We have yet to notice those cases of spontaneous recovery which have taken place after execution, and which are too well authenticated to admit of doubt; upon this point we would observe, that such results by no means militate against the accuracy of the physiological views which have been already presented to our readers. Whenever such a recovery occurs, the strangulation has never been complete, and feeble motions of the heart have been preserved by imperfect and occasional respirations, during the interval of suspension; this may depend, in a great measure, upon the situation of the noose; if placed at the side of the neck, it would be pulled tight by the weight of the body; but if at the back of the neck, it would be far otherwise. _John Smith_, who was executed at Tyburn on the 24th of December 1705, was cut down in consequence of the arrival of a reprieve, nearly fifteen minutes after he had been turned off, but is said to have been recovered by venesection and other means[72]; Governor _Wall_ was a long time in the act of dying, and it was subsequently discovered that this was owing to an ossified portion of the trachea resisting the pressure of the rope; but the most extraordinary instance of this kind, and one well authenticated, is that of _Margaret Dickson_, of Musselburgh, who was tried and convicted in Edinburgh in the year 1728,
