If the land included in any application to bring land under this Act consists of an estate or plot surveyed by the Government and it is found by survey or otherwise that by reason of erroneous measurements in the original Government survey the actual dimensions of the estate or plot as marked on the ground exceed or fall short of the dimensions given in the grant of the land, the Registrar may issue a certificate in respect of that land as if the dimensions marked on the ground had been the dimensions given in the grant.
