Upon this a remarkable reaction sooner or later took place.
Those who were in convulsions felt themselves raised from the lowest depths of misery and despair to the most exalted bliss, and triumphantly shouted out that their bonds were loosed, their sins were forgiven, and that they were translated to the wonderful freedom of the children of God.

In the meantime their convulsions continued, and they remained during this condition so abstracted from every earthly thought that they stayed two and sometimes three days and nights together in the chapels, agitated all the time by spasmodic movements, and taking neither repose nor nourishment.

According to a moderate computation, 4,000 people were, within a very short time, affected with this convulsive malady.
The course and symptoms of the attacks were in general as follows:--There came on at first a feeling of faintness, with rigour and a sense of weight at the pit of the stomach, soon after which the patient cried out, as if in the agonies of death or the pains of labour.

The convulsions then began, first showing themselves in the muscles of the eyelids, though the eyes themselves were fixed and staring.

The most frightful contortions of the countenance followed, and the convulsions now took their course downwards, so that the muscles of the neck and trunk were affected, causing a sobbing respiration, which was performed with great effort.
