The observations themselves seem to require a somewhat greater correction to the watch,

Immediately after these observations, the bearing of the Sun and of a terrestrial mark 
were taken with the theodolite, and then a series of bearings by compass of the same terrestrial 
mark and some other points, which were useful for the reduction of the observations taken on
