    Just by chance I have just come across

    Surveyor's Field Book - Charles Henry Kettle - Lunar and Other Observations at Koputai [Port Chalmers]   1846

    http://ndhadeliver.natlib.govt.nz/delivery/DeliveryManagerServlet?dps_pid=IE25210098

    A quick glance reveals

    Mr Baily's formula for clearing the lunar distance

    Spica and moon observatons

    Observations of regulas for finding rate of watch

    Comparing culmination times of regulus and moon

    Unfortunately there aren't any page numbers I can quote so if you are interested you will have to search the field book yourself.

    It would be  30 years before the first interrnational telegraph cable came ashore in New Zealan dcame into use.
