| contd :- -7- greatest amplitude to the vibration and are slightly lower than we found before using the recording apparatus because of the inertia of the plate carrying this apparatus which we bolt to the crankshaft. We next intend to test a Silver Ghost(1907 40/50 historic RAC 15,000 miles trial) for vibrations and determine the efficiency of the slipper wheels. At present we are measuring the torsional rigidity of the Phantom crankshaft and will do the same for the Silver Ghost(1907 40/50 historic RAC 15,000 miles trial).
