The guillotine was originally offered as a humane method of execution — but rumors circulated that a sudden, clean decapitation did not always kill the prisoner. In 1905 a Dr. Beaurieux examined the just-removed head of Henri Languille:

I called in a strong, sharp voice: ‘Languille!’ I saw the eyelids slowly lift up, without any spasmodic contractions — I insist advisedly on this peculiarity — but with an even movement, quite distinct and normal, such as happens in everyday life, with people awakened or torn from their thoughts.

Next Languille’s eyes very definitely fixed themselves on mine and the pupils focused themselves. I was not, then, dealing with the sort of vague dull look without any expression that can be observed any day in dying people to whom one speaks. I was dealing with undeniably living eyes which were looking at me. After several seconds, the eyelids closed again. … It was at that point that I called out again and, once more, without any spasm, slowly, the eyelids lifted and undeniably living eyes fixed themselves on mine with perhaps even more penetration than the first time. Then there was a further closing of the eyelids, but now less complete. I attempted the effect of a third call; there was no further movement — and the eyes took on the glazed look which they have in the dead.

Perhaps hanging is easier. From the Quarterly Review, September 1849, quoted in Notes and Queries, July 4, 1874:

An immense number of persons recovered from insensibility have recorded their sensations, and agree in the report that an easier end [than hanging] could not be desired. An acquaintance of Lord Bacon, who meant to hang himself partially, lost his footing, and was cut down at the last extremity, having nearly paid for his curiosity with his life. He declared that he felt no pain, and his only sensation was of fire before his eyes, which changed first to black and then to sky-blue. These colours are even a source of pleasure. A Captain Montagnac, who was hanged in France during the religious wars, and rescued from the gibbet at the intercession of Viscount Turenne, complained that, having lost all pain in an instant, he had been taken from a light of which the charm defied description. Another criminal, who escaped by the breaking of the cord, said that, after a second of suffering, a fire appeared, and across it the most beautiful avenue of trees. Henry IV. of France sent his physician to question him, and when mention was made of a pardon, the man answered coldly that it was not worth the asking.

On Saturday night last, a man who resided in Twenty-ninth-street was killed in a most singular manner. The following are the peculiar circumstances, as far as our reporter has been able to learn them — for, in consequence of the opinion entertained concerning his relatives by the deceased, who was a man of considerable wealth and respectability, they have made great effort to keep the particulars from the public ear. It appears that nearly a year ago the deceased, who was fifty-three years of age, became strongly impressed with an idea that, when he should die, the parsimonious disposition of his relatives would lead them to put him in a cheap coffin, while he had a strong desire to be buried in one of polished rosewood, lined with white satin and trimmed with silver. Soon after this strange idea got possession of his mind, he discovered an elegant coffin in one of the principal warehouses, which suited him. He purchased it for $75; had it sent to his residence at nightfall, and stowed it away in a small closet adjoining his bed-room, where it remained until the time of the accident. How it occurred is not known to a certainty, for the first intimation the family had of the lamentable occurrence was from a servant, who, on going to call him to breakfast, found the door wide open and the deceased lying upon the floor, dead, with his coffin at his side. She screamed, which soon brought the family, and on raising the body the skull was found crushed in upon the brain. He was discovered about 8 o’clock yesterday morning, when, to all appearance, he had been dead several hours. On examining the closet, a bottle containing a quantity of sherry wine was found, and as Saturday night was excessively warm, he is supposed to have gone to the closet in order to procure the wine to use with some ice-water he had on a small table by his bedside. It is thought that he must have sought for it in the dark, and by some mistake upset the coffin, which stood nearly upright. Becoming sensible that it was falling, he probably made an effort to get away, when he fell, and the outer end struck his head with sufficient force to fracture his skull and cause almost immediate death. The inquest will be held with all possible secrecy. The unfortunate impression of the deceased concerning his relatives is a sufficient reason for withholding the names of the parties.

— New York Times, July 28, 1856

From the New Ulm [Minn.] Weekly Review, 1886, on a recent surge in U.S. suicides:

The reasons assigned for some of the suicides are silly in the extreme, and some of the methods employed uniquely horrible. One woman killed herself because her mother did, and another because she had a pimple on her nose. … One young woman killed herself because her parents would not allow her to become a Mormon, and a New Yorker shot himself because he hadn’t a nickel to put in the collection box at church. … Several persons died in incalculable agony by jumping into fiery furnaces, and others saturated their clothing with kerosene oil and set it on fire. Still others clumsily sought death by crawling back and forth through barbed-wire fences, entailing great suffering, until they died from exhaustion, and others drove spikes through their brains. Shooting was the most popular method employed, with poison a good second. The most unique example was that of a man who impaled himself on his wooden leg.
