MR. LUBBOCK’S NOTE ON THE TIDES IN THE PORT OF LONDON. 597 
This Table contains the results of a comparison of the predicted times of 
high water at the London Docks, with observations of the same, made morn- 
ing and afternoon, in the months of January, February, and March, 1832. 
The predicted times have been deduced from Bulpit’s Tide Tables, White’s 
Ephemeris, and the British Almanac. 
Bulpit’s Tables contain the mean time of high water at the entrance gate 
of the East India Docks. The time of high water at the London Docks has 
been found by adding twenty minutes to the time given by Bulpit. 
White’s Ephemeris and the British Almanac give the time of high water 
at London Bridge : these times have been decreased by ten minutes, to obtain 
the time for the London Docks. 
M denotes the morning 
> tides. 
A afternoon J 
B denotes the time of high water at the London Docks, as deduced from 
Bulpit’s Tables. 
G do. from White’s Ephemeris. 
L do. from British Almanac. 
O do. as observed. 
Wherever blanks occur, it is to be understood that there has not been any 
tide observed or predicted, — as on the afternoon of Jan. 15 ; or that the objects 
of comparison fail, as on the afternoon of Feb. 13, and morning of the 14th, 
where Bulpit would indicate a tide at 1 l h 52 m , which did not in fact occur, 
and give no tide for the morning of the 14th to compare with an observation 
on that day.
