Amongst the numerous pieces of folk-lore in Ceylon in connexion with snakes, is the belief that a deadly enmity subsists between the polonga and the cobra de capello, and that the latter, which is naturally shy and retiring, is provoked to conflicts by the audacity of its rival. Hence the proverb applied to persons at enmity, that "they hate like the polonga and cobra." The Singhalese believe the polonga to be by far the most savage and wanton of the two, and they illustrate this by a popular legend, that once upon a time a child, in the absence of its mother, was playing beside a tub of water, which a cobra, impelled by thirst during a long-continued drought, approached to drink, the unconscious child all the while striking it with its hands to prevent the intrusion. The cobra, on returning, was met by a tic-polonga, which seeing its scales dripping with delicious moisture, entreated to be told the way to the well. The cobra, knowing the vicious habits of the other snake, and anticipating that it would kill the innocent child which it had so recently spared, at first refused, and only yielded on condition that the infant was not to be molested. But the polonga, on reaching the tub, was no sooner obstructed by the little one, than it stung him to death.] [Footnote 2: In a return of 112 coroners' inquests, in cases of death from wild animals, held in Ceylon in five years, from 1851 to 1855 inclusive, 68 are ascribed to the bites of serpents; and in almost every instance the assault is set down as having taken place _at night_. The majority of the sufferers were children and women.] [Footnote 3: PLINY notices that the serpent has the sense of hearing more acute than that of sight; and that it is more frequently put in motion by the sound of footsteps than by the appearance of the intruder, "excitatur pede sæpius."--Lib, viii. c. 36.]
