Trinity College, Dublin - HL describes the tidal work they are conducting: 'We have two series of observations - one of the heights of each high and low water, without reference to time; and the other of both heights and times of all the spring and neap tides observed throughout the semidiurnal period, at intervals of 15 minutes'. They have a complete series for 1851. Professor Haughton [Samuel Haughton?] has undertaken to work out the results using George Airy's method. The tide gauges are self-registering as to height but not as to time.
