The first defendant contends that in the circumstances of the present case a power to appoint is incidental to the grant of a power to approve.
13 In my opinion the plaintiff's argument is without merit. Even without the assistance of s 49(4), the plain and ordinary understanding of the words used carry the meaning suggested by the first defendant.
