I am indebted to the courtesy of Captain Washington, R. N., Hydrographer to the Navy, for the opportunity I have had of investigating the tides of Port Leopold. Having heard that I was engaged in the discussion of the Arctic Tides, he kindly placed at my disposal the observations made on board Her Majesty’s Ship 'Investigator,’ during the expedition of 1848-49, under the orders of Sir James C. Ross, R. N., in search of Sir John Franklin. The 'Investigator’ was anchored, or rather fast in the ice, during the winter of 1848, in Port Leopold, North Somerset, lat. 74°N., long. 90°W., in three fathoms water; and the observations on the tides were made by Lieut. Frederick Robinson, whose care and skill in observing are highly to be commended. By carefully laying down the daily high and low waters, I have succeeded in completely separating the Diurnal from the Semidiurnal Tide, and in resolving each tide into the portions due respectively to the action of the Sun and of the Moon.
