It is, doubtless,perfectly clear to the thinking man,that if we obtain the location of thispoint, longitudinally and vertically, thatwe have it transversely, inasmuch as theplane surface representing the centre ofthe vessel transversely, must of neces-sity confine its transverse location tothat plane, as the exact location of thecentre of displacement is a vastly im- / ^ \ ^ .——- /.
