tg6 Farther observations on the current that often 
is a current generally, if not constantly, running up the Bri- 
tish Channel ; that is, the eastern tides are the strongest ; and 
in stormy weather from the west, run longer than the western, 
(or ebb) tides. At the same time the level of the channel is 
raised two feet or more, above that of the North Sea ; and 
consequently, the former will discharge plentifully into the 
latter. Here then, is an acceleration of the current ; and which 
men who have the charge of piloting of ships, ought to have 
known. And who can be ignorant of the high level of the 
Channel, when they know that the ports in the Channel are 
some feet deeper in strong westerly winds, than at ordinary 
times ? 
Although the following remarks do not apply to the Stilly , 
or Thwart current, yet as relating to currents, that at all times 
affect the navigation around the British Islands ; it is hoped 
that the utility of inserting them, may atone for their being 
out of place. 
It is proper to state, that the facts here set forth, are assumed, 
on the ground of detached notices, and not from a connected 
chain of observation. Indeed it could hardly have been ex- 
pected. And it is also proper to be stated, that the currents 
here intended, only form a portion of the ordinary stream of 
tide, along the coast. And it is the difference between the 
degrees of velocity of the opposite streams, on the same 
coast, that constitutes the current in question : as indeed, it 
cannot be manifested, in any other way. An instance has 
just been given in the British Channel. 
Where rivers form any quantity of alluvial ground, at their 
entrance into the sea, there, most infallibly, the direction of the
