Short summary
An electronic data set of tidal measurements at St. Helena in 1761 by Nevil Maskelyne is described. These data were first analysed by Cartwright in papers on changing tides, but his data files were never archived.

Our main conclusion is that the major tidal constituent (M2) has changed little.
