Frank, those blue papers are very similar to the one you submitted a month ago or so. Most of the observations are reduced by that same person, except for a few observations in "blue-4". The biggest problem in the analyze was to find out the order of the observations, but I believe I've managed that.
In total there are 32 time sight reductions belonging to two different voyages, apparently made in 1855. The first voyage "begins" 28 July in 52N 25W and ends 18 August in 42N 69W, seems to be a voyage from Ireland or the Channel towards the Boston area. The second voyage contains four observations between 22 October in 31N 72W and 26 October in 27N 75W. In the first voyage the chronometer is gaining 12s a day and the navigator has put some efforts into interpolation of chronometer correction; in the second one the rate has been reduced to 2s a day.
Enclosed is a summary of my findings. I have numbered the observations from 1 starting top left, going down, then next column going down, etc.
