Thirteen cases of death following rattlesnake and copperhead bite in which satisfactory clinical data were obtainable, are given by Prentiss Willson. Of the victims, five were young children, one was a fourteen-year-old boy, one a chronic drunkard, and one a leper who submitted to the stroke of a captive rattlesnake in the mad hope that it would cure his affliction. It did—in twenty-four hours. Of the remaining five, three were dosed with alcohol in large quantities. In several of the cases, notably those of the children, there seemed to be at least an even chance of recovery, when the ligatures binding the affected limb were loosened to relieve the pain, with quickly fatal results. Two of the fatalities were attributed, not immediately to the venom, but to the secondary blood-poisoning, this being the case with the only copperhead bite in the list.
Death resulting typically from crotaline poisoning occurred in two instances, one the fourteen-year-old boy, who was struck by a large rattlesnake and died in six hours, despite skilled and prompt medical attendance; the other, a Dr. Post, into whose veins, it would appear, the poison entered immediately, since a jet of blood spurted from the wound inflicted by the captive rattlesnake. The man passed from great agony into coma, from which he never rallied, death ensuing in five hours after the bite. There is nothing in these data to indicate that a full-grown man in normal health, and with proper treatment, will succumb to crotaline poisoning unless the venom enters a vein, direct.
In the matter of the comparative potency of snake poisons, there are apparent contradictions. In the order of recorded fatalities, the rattlesnake ranks easily first, with the water moccasin a rather distant second, and the copperhead a very poor third. Yet experiments upon animals indicate that moccasin venom is five times as powerful as rattlesnake, though only three times as powerful as copperhead. Taking the cobra as the basis of estimate, it requires only twice as much moccasin venom as it does cobra poison to kill a guinea pig, whereas it requires six times as much copperhead and ten times as much rattlesnake virus. Why, then, is the rattler pre-eminent over its more virulent cousins? Probably for two reasons—the greater amount of venom secreted, and the superior power with which the rattler drives its fangs home.
NO VIPERS IN THIS COUNTRY
Fully as much terror attaches, in the country districts, to the puff adder or sand viper as to the rattlesnake or copperhead. This is a suggestive bit of superstition, since there's no such thing as an adder or viper on the Western hemisphere and never has been one, unless it came, carefully pickled, in a jar. What passes for the supposedly deadly reptile is the common hog-nosed or bull snake. It is about as dangerous as an infuriated rabbit. But it puts up one of the best "bluffs" known to natural history. When caught at its favorite occupation of basking in the open, without convenient avenue of escape, it flattens its head, and strikes right and left, blowing and hissing with an aspect much more terrifying than that of the truly venomous species. Then, when the objects of its fury have taken to trees or adjacent fences, it glides quietly away into the grass and effaces itself. Any one who has the nerve to look it between the eyes may uncover its pretense. For by this token may be known the real Crotalids from the mock: a small but distinct pit between eye and nostril. Lacking this mark, no ventral crawler in the land of the free need cause a flutter in the most timid breast, with one notable exception.
BEWARE THE ELAPS
Shun, as you would a rabid dog, a pretty little red-and-black banded serpent about as thick as your thumb. If any living creature whose habitat is the United States deserves the epithet "deadly," it is the Elaps. Two species are known; the harlequin snake, which ranges throughout the Gulf states to Texas and up the Mississippi River to Ohio, and the Sonoran coral snake, found in the Southwest only. By a strange perversion of facts, while the harmless hog-nosed snake enjoys a repute of terror, the Elaps, most dangerous of all American reptiles, is commonly regarded as harmless. Partly this is due to its slight and graceful prettiness, partly to its innocent-appearing head, which shows no flattening (the popularly understood mark of the venomous species), and partly to its lethargic and peaceful disposition. Experimenters wishing to secure the venom of the Elaps often find it difficult to rouse the snake to striking wrath.
Very few instances are known of Elaps bite, but those few unquestionably set this ornamental creature in a class by itself, among American Ophidia, for "results." Out of eight well-authenticated cases of Elaps bite, six of the victims died. This is believed to indicate a falsely large percentage, however, the scientific estimate of mortality being somewhere between twenty-five and fifty per cent.
A government scientist tells me of a curious result from coral-snake bite which came under his notice. The victim, who was handling the reptile preparatory to photographing it, apparently overstepped the bounds of its habitual forbearance, for it fastened upon his finger with such determination that it had to be pried off. The man soon became unconscious, but rallied, and, after three days of dubious condition, recovered. Every year since, at about the anniversary of the bite, an ulcer forms upon the finger and the nail sloughs off. I have heard of similar recurrent effects from crotaline poisoning, but none scientifically attested, as is this phenomenon.
Before passing from the subject of snakes, let me make one point clear. While the venomous snakes of this country are by no means "deadly" in the ordinary sense of the term, their bite is always serious, both in its immediate effects and in the possibility of after effects. The bitten person should get to a physician at once. The immediate treatment is prompt incision and sucking of the wound. Permanganate of potash for rubbing into the bitten place should always be carried by persons traveling in a snake-infested country. If the bite is on a limb, a light ligature will check the spread of the venom. Use whisky sparingly, if at all, and then only in case of complete collapse.
