The document discusses two exceptions to the hearsay rule: 1) Dying declarations, which allow statements made by a dying person about the cause and circumstances of their death. For a dying declaration to be admissible, the person must believe their death is imminent. 2) Statements by a decedent or person of unsound mind, which allow statements made by such individuals about matters they personally witnessed to be used as evidence in cases involving their estate or representative. The statements must have been made soon after perceiving the matter while their memory was clear.
