Leopards are strongly attracted by the peculiar odour which accompanies small-pox. The reluctance of the natives to submit themselves or their children to vaccination exposes the island to frightful visitations of this disease; and in the villages in the interior it is usual on such occasions to erect huts in the jungle to serve as temporary hospitals. Towards these the leopards are certain to be allured; and the medical officers are obliged to resort to increased precautions in consequence. This fact is connected with a curious native superstition. Amongst the avenging scourges sent direct from the gods, the Singhalese regard both the ravages of the leopard, and the visitation of the small-pox. The latter they call _par excellence "maha ledda_," the great "sickness;" they look upon it as a special manifestation of _devidosay_, "the displeasure of the gods;" and the attraction of the cheetahs to the bed of the sufferer they attribute to the same indignant agency. A few years ago, the capua, or demon-priest of a "dewale," at Oggalbodda, a village near Caltura, when suffering under small-pox, was devoured by a cheetah, and his fate was regarded by those of an opposite faith as a special judgment from heaven. Such is the awe inspired by this belief in connection with the small-pox, that a person afflicted with it is always approached as one in immediate communication with the deity; his attendants, address him as "my lord," and "your lordship," and exhaust on him the whole series of honorific epithets in which their language abounds for approaching personages of the most exalted rank. At evening and morning, a lamp is lighted before him, and invoked with prayers to protect his family from the dire calamity which has befallen himself. And after his recovery, his former associates refrain from communication with him until a ceremony shall have been performed by the capua, called _awasara-pandema_, or "the offering of lights for permission," the object of which is to entreat permission of the deity to regard him as freed from the divine displeasure, with liberty to his friends to renew their intercourse as before. Major SKINNER, who for upwards of forty years has had occasionally to live for long periods in the interior, occupied in the prosecution of surveys and the construction of roads, is strongly of opinion that the disposition of the leopard towards man is essentially pacific, and that, when discovered, its natural impulse is to effect its escape. In illustration of this I insert an extract from one of his letters, which describes an adventure highly characteristic of this instinctive timidity:--
