Others shouted aloud, leaped about, and threw their bodies into every possible posture, until they had exhausted their strength.

Yawning took place at the commencement in all cases, but as the violence of the disorder increased the circulation and respiration became accelerated, so that the countenance assumed a swollen and puffed appearance.

When exhaustion came on patients usually fainted, and remained in a stiff and motionless state until their recovery.

The disorder completely resembled the St.
Vitus's dance, but the fits sometimes went on to an extraordinarily violent extent, so that the author of the account once saw a woman who was seized with these convulsions resist the endeavours of four or five strong men to restrain her.

Those patients who did not lose their consciousness were in general made more furious by every attempt to quiet them by force, on which account they were in general suffered to continue unmolested until nature herself brought on exhaustion.
