THE GYRO-COMPASS CARD to heat, and means are provided forreplacing bearings if necessary. The axle of the gyro is a flexibleone, of the de Laval type, so thatthe centre of gravity of the wholerotating mass coincides with the axisof rotation as soon as a certain criti-cal speed is attained. The friction between the suspendedmoving system and the mercury inthe bowl is not sufficient to cause avisible decrease in the amplitude ofthe oscillations of the gyro on eitherside of the meridian, and the swing-ing would be continuous if a damp-ing system were not employed.
