On some tide observations at Hobart during February and March, 1889

Wishing, primarily in connection with the obtaining of necessary information for purposes connected with the drainage of Hobart, and secondarily, to fix the mean sea level for geodetic and engineering matters, to get a series of tidal observations, I spoke to Captain Oldham, of H.M.S. "Egeria," on the subject and he at once arranged to fix the automatic tide gauge of his ship on the New Wharf, and to have observations taken for as long a period as the sojourn at Hobart permitted. I am indebted to him for the accompanying remarks and tables of observations.
