(1) When the executor or administrator is a legatee, his assent to his own legacy is necessary to complete his title to it, in the same way as it is required when the bequest is to another person, and his assent may, in like manner, be expressed or implied.
     (2) Assent shall be implied if in his manner of administering the property he does any act which is referable to his character of legatee and is not referable to his character of executor or administrator.
