There was a famous diver in Sicily at the end of the fifteenth century whose feats are recorded in the writings of Alexander ab Alexandro, Pontanus, and Father Kircher, the Jesuit savant. This man's name was Nicolas, born of poor parents at Catania. From his infancy he showed an extraordinary power of diving and swimming, and from his compatriots soon acquired various names indicative of his capacity. He became very well known throughout Sicily, and for his patron had Frederick, King of Naples. In the present day, the sponge-fishers and pearl-fishers in the West Indies, the Mediterranean, the Indian Seas, and the Gulf of Mexico invite the attention of those interested in the anomalies of suspended animation. There are many marvelous tales of their ability to remain under water for long periods. It is probable that none remain submerged over two minutes, but, what is more remarkable, they are supposed to dive to extraordinary depths, some as much as 150 to 200 feet. Ordinarily they remain under water from a minute to one and a half minutes. Remaining longer, the face becomes congested, the eyes injected; the sputum bloody, due to rupture of some of the minute vessels in the lung. It is said by those who have observed them carefully that few of these divers live to an advanced age. Many of them suffer apoplectic attacks, and some of them become blind from congestion of the ocular vessels. The Syrian divers are supposed to carry weights of considerable size in their hands in order to facilitate the depth and duration of submersion. It is also said that the divers of Oceanica use heavy stones. According to Guyot-Daubes, in the Philippine Isles the native pearl-fishers teach their children to dive to the depth of 25 meters. The Tahitians, who excited the admiration of Cook, are noted for their extraordinary diving. Speaking of the inhabitants of the island of Fakaraya, near Tahiti, de la Quesnerie says that the pearl-fishers do not hesitate to dive to the depth even of 100 feet after their coveted prizes. On the Ceylon coast the mother-of-pearl fishers are under the direction of the English Government, which limits the duration and the practice of this occupation. These divers are generally Cingalese, who practice the exercise from infancy. As many as 500 small boats can be seen about the field of operation, each equipped with divers. A single diver makes about ten voyages under the water, and then rests in the bottom of the boat, when his comrade takes his place. Among other native divers are the Arabs of Algeria and some of the inhabitants of the Mexican coast.
It might be well to mention here the divers who work by means of apparatus. The ancients had knowledge of contrivances whereby they could stay under water some time. Aristotle speaks of an instrument by which divers could rest under water in communication with the air, and compares it with the trunk of an elephant wading a stream deeper than his height. In the presence of Charles V diving bells were used by the Greeks in 1540. In 1660 some of the cannon of the sunken ships of the Spanish Armada were raised by divers in diving bells. Since then various improvements in submarine armor have been made, gradually evolving into the present perfected diving apparatus of to-day, by which men work in the holds of vessels sunk in from 120 to 200 feet of water. The enormous pressure of the water at these great depths makes it necessary to have suits strong enough to resist it. Lambert, a celebrated English diver, recovered L90,000 in specie from the steamer Alphonso XII, a Spanish mail boat belonging to the Lopez line, which sank off Point Gando, Grand Canary, in 26 1/2 fathoms of water. For nearly six months the salvage party, despatched by the underwriters in May, 1885, persevered in the operations; two divers lost their lives, the golden bait being in the treasure-room beneath the three decks, but Lambert finished the task successfully.
Deep-sea divers only acquire proficiency after long training. It is said that as a rule divers are indisposed to taking apprentices, as they are afraid of their vocation being crowded and their present ample remuneration diminished. At present there are several schools. At Chatham, England, there is a school of submarine mining, in which men are trained to lay torpedoes and complete harbor defense. Most of these divers can work six hours at a time in from 35 to 50 feet of water. Divers for the Royal Navy are trained at Sheerness. When sufficiently trained to work at the depth of 150 feet seamen-divers are fully qualified, and are drafted to the various ships. They are connected with an air-pump in charge of trustworthy men; they signal for their tools and material, as well as air, by means of a special line for this purpose. At some distance below the water the extraordinary weight of the suits cannot be felt, and the divers work as well in armor as in ordinary laboring clothes. One famous diver says that the only unpleasant experience he ever had in his career as a diver, not excepting the occasion of his first dive, was a drumming in the ears, as a consequence of which, after remaining under water at a certain work for nine hours, he completely lost the use of one ear for three months, during which time he suffered agony with the earache. These men exhibit absolute indifference to the dangers attached to their calling, and some have been known to sleep many fathoms beneath the surface. Both by means of their signal lines and by writing on a slate they keep their associates informed of the progress of their work.
Suspension of the Pulse.—In some cases the pulse is not apparent for many days before actual death, and there have been instances in which, although the pulse ceased for an extended period, the patient made an ultimate recovery. In reviewing the older literature we find that Ballonius mentions an instance in which the pulse was not apparent for fourteen days before complete asphyxia. Ramazzini describes a case of cessation of the pulse four days before death. Schenck details the history of a case in which the pulse ceased for three days and asphyxia was almost total, but the patient eventually recovered. There is a noteworthy observation, in which there was cessation of the pulse for nine days without a fatal issue.
Some persons seem to have a preternatural control over their circulatory system, apparently enabling them to produce suspension of cardiac movement at will. Cheyne speaks of a Colonel Townshend who appeared to possess the power of dying, as it were, at will,—that is, so suspending the heart's action that no pulsation could be detected. After lying in this state of lifelessness for a short period, life would become slowly established without any consciousness or volition on the man's part. The longest period in which he remained in this death-like condition was about thirty minutes. A postmortem examination of this person was awaited with great interest; but after his death nothing was found to explain the power he possessed over his heart.
Saint Augustin knew of a priest named Rutilut who had the power of voluntarily simulating death. Both the pulsation and respiration was apparently abolished when he was in his lifeless condition. Burning and pricking left visible effects on the skin after his recovery, but had no apparent effect on his lethargy. Chaille reports an instance of voluntary suspension of the pulse.
Relative to hibernation, it is well-known that mice, snakes, and some reptiles, as well as bees, sometimes seem to entirely suspend animation for an extended period, and especially in the cold weather. In Russia fish are transported frozen stiff, but return to life after being plunged into cold water. A curious tale is told by Harley, from Sir John Lubbock, of a snail brought from Egypt and thought to be dead. It was placed on a card and put in position on a shelf in the British Museum in March, 1845. In March, 1850 after having been gummed to a label for five years, it was noticed to have an apparent growth on its mouth and was taken out and placed in water, when it soon showed signs of life and ate cabbage leaves offered to it. It has been said, we think with credible evidence, that cereal seeds found in the tombs with mummies have grown when planted, and Harley quotes an instance of a gentleman who took some berries, possibly the remnants of Pharaoh's daughter's last meal, coming as they did from her mummified stomach after lying dormant in an Egyptian tomb many centuries, and planted them in his garden, where they soon grew, and he shortly had a bush as flourishing as any of those emanating from fresh seeds.
Human hibernation is an extremely rare anomaly. Only the fakirs of India seem to have developed this power, and even the gifted ones there are seldom seen. Many theories have been advanced to explain this ability of the fakirs, and many persons have discredited all the stories relative to their powers; on the other hand, all who have witnessed their exhibitions are convinced of their genuineness. Furthermore, these persons are extremely scarce and are indifferent to money; none has been enticed out of his own country to give exhibitions. When one dies in a community, his place is never filled—proving that he had no accomplices who knew any fraudulent secret practices, otherwise the accomplice would soon step out to take his place. These men have undoubtedly some extraordinary mode of sending themselves into a long trance, during which the functions of life are almost entirely suspended. We can readily believe in their ability to fast during their periods of burial, as we have already related authentic instances of fasting for a great length of time, during which the individual exercised his normal functions.
To the fakir, who neither visibly breathes nor shows circulatory movements, and who never moves from his place of confinement, fasting should be comparatively easy, when we consider the number of men whose minds were actively at work during their fasts, and who also exercised much physical power.
Harley says that the fakirs begin their performances by taking a large dose of the powerfully stupefying "bang," thus becoming narcotized. In this state they are lowered into a cool, quiet tomb, which still further favors the prolongation of the artificially induced vital lethargy; in this condition they rest for from six to eight weeks. When resurrected they are only by degrees restored to life, and present a wan, haggard, debilitated, and wasted appearance. Braid is credited, on the authority of Sir Claude Wade, with stating that a fakir was buried in an unconscious state at Lahore in 1837, and when dug up, six weeks later, he presented all the appearances of a dead person. The legs and arms were shrunken and stiff, and the head reclined on the shoulder in a manner frequently seen in a corpse. There was no pulsation of the heart or arteries of the arm or temple—in fact, no really visible signs of life. By degrees this person was restored to life. Every precaution had been taken in this case to prevent the possibility of fraud, and during the period of interment the grave was guarded night and day by soldiers of the regiment stationed at Lahore.
