A donor, being in extremis, told by a doctor that he was dying, and having no near relatives, gave three bunches of keys to a donee with whose family he had lived for ten years, with the statement, "'If I am going to die, everything I have belongs to this woman." This was held to be a valid gift causa mortis of so much of decedent's property as was thereby made available. In re Elliott's Estate, 312 Pa. 493, 167 Atl. 289 (1933).
