Chapter 9 The ＂Red-Spot＂-Dangerous

   Strangely enough, the one really dangerous spider on the American continent is small, obscure, and practically unknown to popular or journalistic hysteria. Latrodectus mactans is its scientific name. It is about the size of a large pea, black with a red spot on the back -- a useful danger signal -- and spins a small web in outhouses or around wood-piles. So far as is known, its poison is the most virulent¹ and powerful, drop for drop, secreted² by any living creature. Cobra virus, in the minute quantity which the Latrodectus's glands³ contain, would probably have no appreciable⁴ effect upon man; whereas the tiny spider's venom⁵, in the volume injected by the cobra's stroke, would slay⁶ a herd⁷ of elephants. Were this little-known crawler as large as the common black hunting spider of our gardens and lawns, its bite would be almost invariably fatal. Happily, the "red-spot's" fangs⁸, being small and weak, can with difficulty penetrate⁹ the skin, and are able to inject venom in dangerous quantity only when the bite is inflicted¹⁰ upon some tender-skinned portion of the body. Nevertheless, fatalities¹¹ consequent upon the bite of this insect are sufficiently¹² well attested¹³ to take rank as established scientific facts.

   One of the most detailed¹⁴ comes from an intelligent farmer of Greensboro, North Carolina. A workman in his employ, while hauling wood, brushed at something crawling upon his neck and felt a sharp, stinging sensation. He found a small, black spider with a red spot. This was at 8.30 A.M. Presently, ten small white pimples¹⁵ appeared about the bitten spot, though no puncture¹⁶ was visible and there was no swelling¹⁷. The pain soon passed, but returned in three hours and became general, finally settling in the abdomen¹⁸ and producing violent cramps¹⁹. At one o'clock the man had a spasmodic attack. Two hours later he had so far recovered as to be able to go back to work, for an hour. Then the spasms²⁰ took him again; he sank into coma²¹, and died between ten and eleven o'clock that evening, about fourteen hours after the bite. At no time were there local symptoms or swelling, other than the slight eruption²², but the neck, left arm, and breast are reported as having assumed a stonelike hardness.

   The same farmer had seen, three years previous, a negro who had been bitten upon the ankle by a "red-spot" and who suffered from diminishingly severe spasmodic attacks for three weeks. The white pimples appeared in this case also. The negro recovered, but the eruption reappeared for years thereafter whenever he was overheated.

   Recoveries from Latrodectus bite are much more common, in the records, than deaths. Dr. Corson, of Savannah, Georgia, reports six cases, characterized by agonizing²³ pains, spasmodic contractions²⁴ like those of tetanus, and grave general symptoms. All recovered. From Anaheim, California, a fatal case is reported by Dr. Bickford, death occurring twenty hours after the bite. William A. Ball, of San Bernardino, California, gives a vivid account of his sensations after being bitten on the groin by a red-spotted spider, the data being attested by his physician. Shortly after being bitten, he began to suffer great agony, with convulsive contractions of the muscles.

   "The pains in my hip-joints, chest, and thighs²⁵ grew rapidly more violent, until it seemed that the bones in these parts of my body were being crushed to fragments." He was seriously ill for ten days.
