That is, at those intervals they attend to the apparent motions, and to the battement of sounds of the bodies around them, and for a moment mistake them for those real motions of the ship, and noise of wheels, which they had lately been accustomed to: or at these intervals of reverie, or on the approach of sleep, these supposed motions or sounds may be produced entirely by imagination.

Battèment of the sound of bells and organ-pipes. Vertiginous noise in the head. Irritative motions of the stomach, intestines, and glands. 8. Symptoms that accompany vertigo. Why vomiting comes on in strokes of the palsy. By the motion of a ship. By injuries on the head. Why motion makes sick people vomit. 9. Why drunken people are vertiginous.

Souvenez-vous, j'ai glisse dans le sang quand je suis entre ici. Aussi j'ai entendu un battement d'ailes dans l'air, un battement d'ailes gigantesques. Ce sont de tres mauvais presages. Et il y en avait d'autres. Je suis sur qu'il y en avait d'autres, quoique je ne les aie pas vus. Eh bien! Salome, vous ne voulez pas qu'un malheur m'arrive? Vous ne voulez pas cela. Salome.

Secondly, though there is an audible vertigo, as is known by the battement, or undulations of sound in the ears, which many vertiginous people experience; and though there is also a tangible vertigo, as when a blind person turns round, as mentioned above; yet as this circumgyration of objects is an hallucination or deception of the sense of sight, we are to look for the cause of our appearing to move forward, when we stop with our eyes closed after gyration, to some affection of this sense.

The vibrations of the two organ-pipes may be compared to Nonius's rule; the sound is louder, when they coincide, and less at the intermediate times. But, as the sound of bells is the most familiar of those sounds, which have a considerable battement, the vertiginous patients, who attend to the irritative circles of sounds above described, generally compare it to the noise of bells.

Tout en disant ainsi, je jette ma pierre d'une main tremblante, et avec un horrible battement de coeur, mais si heureusement qu'elle va frapper au beau-milieu de l'arbre: ce qui veritablement n'etoit pas difficile: car j'avois eu soin de le choisir fort gros et fort pres. Depuis lors je n'ai plus doubte de mon salut.
