TO IMAGINE, Eng. law. In cases of treason the law makes it a crime to imagine the death of the king. In order to complete the offence there must, however, be an overt act the terms compassing and imagining being synonymous. It. has been justly remarked that the words to compass and imagine are too vague for a statute whose penalty affects the life of a subject. Barr. on the Stat. 243, 4. Vide Fiction.
