The late Sir J. Emerson Tennent mentions that "the Cinghalese remark that if one Cobra be destroyed near a house, its companion is almost certain to be discovered immediately after--a popular belief which I had an opportunity of verifying on more than one occasion. Once, when a Snake of this description was killed in a bath of the Government House at Colombo, its mate was found in the same spot the day after; and again, at my own stables, a Cobra of five feet long having fallen into the well, which was too deep to permit its escape, its companion, of the same size, was found the same morning in an adjoining drain.[14] On this occasion the Snake, which had been several hours in the well, swam with ease, raising its head and hood above water; and instances have repeatedly occurred of the Cobra di capella voluntarily taking considerable excursions by sea" (or by rivers, as the writer has personally witnessed).] [14] "Pliny," remarks Sir J. E. Tennent, "notices the affection that subsists between the male and female Asp (or African Cobra); and that if one of them happens to be killed, the other seeks to avenge its death"--lib. viii. c. 37. Cobras are much dreaded, for they instil the most subtle poison into their bites. Their manners are very singular. When at rest the neck of the animal is no larger in diameter than the head; but when under the influence of passion and irritation the neck swells at the same time that the animal raises the front part of his body vertically, holding this part straight and rigid as an iron bar. The lower part of the body rests upon the ground, and serves as a support to the upper part, which is movable and capable of locomotion. This faculty of dilating the neck is as striking a trait in the organization of the Cobras, as the rattle is in _Crotalus_. The ancient inhabitants of Egypt adored them; they attributed to their protection the preservation of grain, and allowed them to live in the midst of their cultivated fields. The Cobra is no longer an object of adoration in the East, but is held sacred by many people, and it serves in nearly every country of Asia as a very curious spectacle; being the Serpent chiefly used by snake-charmers in these countries, terrible as it seems to us.
