Thanks for your comments George. I ran the London data through Redshift, an astronomy program, and having adjusted the date accordingly got a 9 minutes difference on Searle?s time of the moon?s meridian passage: 4h 34m. The only other reference to Searle?s Ephemerides is in a repeat of the lunar culmination procedure on 22 June 1615 (Julian). On this occasion, there are no problems, Baffin has a second almanac to consult, gets the moon?s relative motion correct, and the final result is fairly accurate. ...Nowe according to Searle?s Ephemerides, the moone came to the meridian at London at 4 54 30 and after Origamus, the moone came to the meridian at Wittenburg at 4 52 05 the same day..... ...74 degrees 5 minutes which is the latitude of this place west of London because the moone was later on the meridian at this place by 0 10 22....... I hope you are able to consult the copy of Searle?s in the Bodleian Library for the time of the moon?s transit, but this and the earlier one I sent are the only data that appear to be available. Tony
