102.     Severable powers.

A power given to a series of persons may be severable1. For example, if it is given to a named person and others filling, with him, a certain position, as that of trustee, it will be validly exercised by the named person2, or, if given to a living person, his heirs or assigns, it can at all events be exercised by the living person3.
