RECORD AND RESULTS OF 



Progress of the Tide through Baffin Bay. — In the following table I have collected 

 all the tidal information I could find respecting establishment and range of stations 

 on the west coast of Greenland, for the purpose of showing the northerly propaga- 

 tion of the tide wave through Baffin Bay. This locality is well suited for testing 

 the theoretical deductions, according to the tidal theory of canals, the bay being 

 sufficiently regular and of great length, with the full Atlantic tide thrown into it a,t 

 its southern end. Its tides wiU therefore be of a derivative character chiefly, since 

 any forced tide produced in it must be, comparatively very small, and would pro- 

 duce waves of an undulatory character. For this purpose it would be very 

 desirable to obtain some sets of unexceptionable tidal observations^ on both shores 

 of the bay, each extending over at least two lunations.

To trace the cotidal lines or the high water ridges of the tidal Avave, as it pro- 

 gresses, it is preferable, for comparison, to use the mean for the above vrdgar estab- 

 lishment; 10" were therefore subtracted from the interval at full and change. To 

 correct for the moon's motion in the interval, 1° is subtracted for every half hour 

 of interval ; adding the west longitude from Greenwich we obtain the correspond- 

 ing Greenwich time or the cotidal hour and minute.

* Suitable localities would be Cape Farewell, Cape St. Lewis in Labrador, Cape Walsingham, and 

 Ponds Strait. It is to be regretted that no tidal observations were made in Kennedy Channel, a§ 

 by means of these the question of its open or closed character, to the northward, could be partly 

 answered.
