Stern has given some interesting particulars with regard to these seizures. “During the rainy season, when the weather, like the mind, is cheerless and dull, the _boudas_, as if in mockery of the universal gloom, celebrate their saturnalia. In our small settlement, the monotony of our existence was constantly diversified by a _bouda_ scene. Towards the close of August, when every shrub and tree began to sprout and blossom, the disease degenerated into a regular epidemic; and in the course of an evening two, three, and not unfrequently every hut occupied by natives would ring with that familiar household cry. A heavy thunderstorm, by some mysterious process, seemed invariably to predispose the people to the _bouda’s_ torturing influence. “I remember one day, about the end of August, we had a most terrific tempest. . . . The noise and tumult of the striving elements had scarcely subsided, when a servant of Mr. Mayer, a stout, robust, and masculine woman, began to exhibit the _bouda_ symptoms. She had been complaining the whole noon of languor, faintness, and utter incapacity for all physical exertion. About sunset her lethargy increased, and she gradually sank into a state of apparent unconsciousness. Her fellow-servants, who were familiar with the cause of the complaint, at once pronounced her to be possessed. To outwit the conjuror, I thought it advisable to try the effect of strong liquid ammonia on the nerves of the Evil One. The place being dark, faggots were ignited; and in their bright flickering light we beheld a mass of dark figures squatted on the wet floor around a rigid, motionless, and apparently dead woman. I instantly applied my bottle to her nose; but although the potent smell made all near raise a cry of terror, it produced no more effect on the passive and insensible patient than if it had been water from the newly formed rivulets.”
