Final answer:
Dr. Livesey from 'Treasure Island' by Robert Louis Stevenson is both a doctor and a magistrate, with the latter position granting him limited judicial and administrative functions.

Besides being a doctor, Livesey is also a magistrate. Dr. Livesey is a character from the book 'Treasure Island' by Robert Louis Stevenson. In this book, Dr. Livesey serves not only as a doctor but also holds the position of a magistrate, which is an officer of the state. As a magistrate, Dr. Livesey has administrative and limited judicial functions.
