XV. Some Observations on the peculiarity of the Tides between 
Fairleigh and the North Foreland ; with an explanation of 
the supposed meeting of the Tides near Dungeness. By James 
Anderson, Captain in the Royal Navy. Communicated by the 
Right Hon. Sir Joseph Banks, Bart. G. C. B. P. R. S. 
Read March 25, 1819. 
Having observed that several Charts and Books of Navi- 
gation assert, that the tides from the North Sea and the 
Channel, or the Eastern and Western tides, meet in the 
vicinity of Dungeness and Rye harbour ; and that, on such 
authority, this opinion has been too generally adopted by 
those, who have not had the opportunity or the inclination 
of making personal observations ; as well as by the pilots 
on this part of the coast, who from being incapable, for the 
most part, of making observations or deducing inferences 
from facts before them, readily embrace the first theory 
they meet with in print , however erroneous or inconsistent ; 
I have been induced to bestow all the attention in my power 
to the phaenomena of the tides between Fairleigh and the 
North Foreland, and now venture to submit the result of 
my observations to the notice of the Royal Society. From 
having cruised constantly within these limits for nearly two 
years and a half, I have had many opportunities of making 
observations ; but I must, nevertheless, profess my readi- 
ness to admit any alteration or improvement which may be 
pointed out by those more conversant with the subject ; truth 
alone being the object of my enquiries.
