    Thank you, Brad.

    On the 28th,  "1m4' more slow" shall probably be "1m4s more slow", with or without underlined s.

    On the 26th,

       26   7
       30  10

    this shall probably read

    2.23.29      or     2.23.29
    2 26   7                  26   7
    2 30 10                  30 10
    ----------              ----------
    7 19.46                  79 46

    being the sum of three chronometer readings. Divide by three, and you get the mean value 2h26m35s shown below. The mean of the altitudes is perhaps calculated among the x:es top middle or down left?

    Apart from the question of CE determination, I now see only two (there may be more) remaining peculiarities:

    a) April 26th

    16 37
    73.20 x
    13 32 x
    59 47.44

    My impression is that this is the noon observation for latitude. I know that you insist that the last row is correct, but why is the observed position then given as 59°46' above? The next last row should be the declination, 13°32'34" within one or two seconds of arc. Could you please give it another look? As it is now it makes no sense.

    b) 4th May

    N36E 52 41

    Looks like course dlat dep, but the values don't correspond to each other. Please give it a look again!
