In a partly visible, or semi-substantial, state

The London Times of June 24, 1880, relates that at High Easter, Essex, England, the home of the Brewster family was plagued by poltergeist disturbances. Brewster thought he saw a shadowy figure that he “recognized as that of his neighbor, Susan Sharpe.” The man and his son went to the woman’s house, dragged her to a nearby pond, and threw her in to see if she would float or sink. As Fort records, “though once upon a time, this was the scientific thing to do, fashions in science had changed. Brewster and his son were arrest, and were bound over to keep the peace.”
