(All times Cri-umvieli Mean.) The series of six (lots which constitute Hie actual time .simials are transmit led directly from the Dominion Observatory sicniil clock, which is seldom more than 0.25 second in error. Corrections to the time signals, can be r.btained on application to the Observatory. The preparatory and intermediate signals arc .sent, from a .special transmitter and should not be used as time signals.
