Snake Stones and Bezoars: Morocco

Writing of bezoars in the year 1876, Dr. Learned states that Signor Korkos, of Morocco, showed him one for which he had paid twelve dollars. It was as large as a small walnut, the surface being smooth and cream-colored; a section revealed the presence of the concentric circular layers characterizing the formation of this concretion. For remedial use it was rubbed on a stone until a sufficient quantity of its powder was obtained, which was then diluted in liquid and administered as a potion. Strict dieting absolute rest in the house for seven days were an essential part of the treatment, the bezoar powder being more especially recommended in diseases of the heart, liver or other internal organs, but for sore eyes and for rheumatism its virtues were praised. This illustrates a modern employment of the concretion in Mohammedan Morocco.

Some medical authorities of the sixteenth century were disposed to regard the calculus produced by the human subject as superior in medicinal efficacy to the far-famed bezoar. One of their arguments was that as man was the highest type of organized being a human product must exceed in value one from an animal source; then again, his food was of the best, superior in quality to that taken by the animals furnishing the bezoars. For every theory a proof can be found if one is on the lookout for it, and therefore we need not be surprised if the virtues of calculi or gravel were also supported by evidence. In 1624 or 1625 the Dutch city of Leyden was visited by the plague, and to the great regret of the physicians there was no supply of bezoars on hand. Here upon they were driven to make use of human gravel, and found to their astonishment that this was an even more excellent sudorific than the bezoar itself.

Although there is no direct relation between bezoars and the hair-balls sometimes found in the stomach or intestines of human beings, there is some slight analogy, as the animal bezoar concretions seem to have been formed about a nucleus consisting of some indigestible material that has been swallowed by an animal. From the report of hospital surgeons, it appears that these hair-balls, which result from a long-continued habit of swallowing hair, are almost exclusively found in the bodies of women, generally of very young girls. The large size which they sometimes attain is very surprising; in several instances they have so filled up the stomach that they are moulded by it into its exact shape. Although when a hair-ball has reached this size, and indeed long before, the most alarming symptoms set in, frequently recurrent vomiting being the most characteristic, we cannot but wonder how it is possible for any food to enter and pass through the stomach under such conditions, the only explanation being the great power of dilation this organ possesses. Its disposition to patiently tolerate foreign bodies where it cannot expel them, renders it often a poor guide in a diagnosis based upon the patient's personal experience. These hair-balls accumulate and lodge not only in the stomach but also in the intestines, and in either case the eventual result is almost certain to be fatal unless the obstacle is removed by operation. Very occasionally only does nature react sufficiently to expel the impediment without surgical aid. Of course all treatment is vain unless the morbid habit of hair-swallowing can be overcome. This does not seem to be an accompaniment of a distinctly diseased mental condition, although that is sometimes coincident, but must assuredly result from some derangement or abnormality of the nervous centres, inducing a morbid and unnatural craving. The serpent-stone, called by Pliny ovum anguinum, or "serpent's egg," is said to have been worn by the Druid priests as a badge of distinction. Pliny relates that he had seen one of them which was as large as a moderate-sized apple, its shell being a cartilaginous substance. It was supposed to be generated in midsummer out of the saliva and slime exuding from a knot of interwined serpents. When the moisture had coagulated and formed into a sphere, this was tossed in the air by the hissing snakes, and, in order to preserve its efficacy as a talisman, the finder had to catch it in a linen cloth before it fell to the ground. Such "serpent's eggs" were in high favor with the Romans, who believed they procured for the wearers success in all disputes and the protection of kings. So great was the faith reposed in their magical virtues that Claudius is said to have condemned to death a Roman knight, one of the Vecontii, simply because he had an ovum anguinum concealed in his bosom when he appeared in court during the trial of a lawsuit in which he was involved. In order to enhance the value of this amulet, the story was circulated that great dangers were incurred in securing it; for the snakes pursued any one who seized the egg and he could only escape by fording a river, across which they could not swim. In later accounts of this amulet it is described as a ring, sometimes composed of a blue stone with an undulating streak or stripe of yellow, thought to represent a snake. Certain so-called floating-stones have been found in a branch of Mann Creek, a tributary of the Weiser River, which flows into the latter near its confluence with the Snake River in Idaho. These are hollow quartz globes, with a shell so thin that the air in the cavity more than makes up for the specific gravity of the quartz. Some formation similar to this may possibly have been intended by Pliny in his description of the ovum anguinum or serpent's egg of the Druids, which floated if thrown into a stream, although it is perhaps more probable that these "serpent's eggs" were shells of the sea-urchin, as they are figured by De Boot and other writers.
