    Agreed Lars.  One chronometer, one timepiece.

    Brad, you wrote "Until recently, all of the published books show Worsley with just one chronometer on the Caird, yet the log clearly indicates the presence of two chronometers on board".

    Probably not two chronometers. If there were two chronometers onboard, Worsley should have noted the errors for both of them in the log. But they had at least one other timepiece. This other watch were used for timing the observations on April 26th and May 3rd. This watch has errors "fast 29" and "slow 46" respectively. These values must have been obtained by comparison with the chronometer 192/262 shortly before or after each observation.
