39.—Where the Council is of opinion that any branch of practice of veterinary medicine (including a specialty standing prescribed by the Council under section 46) has become so distinctive that it would be for the convenience of the public or of the veterinary profession that veterinary practitioners who are qualified to practise in that branch of veterinary medicine should use a distinctive title, the Council may, by regulations, provide for appropriate titles to be given to and used by such practitioners and the conditions under which such titles may be used.
