The tidal observations at Liverpool are recorded from the Old Dock 
sill. In the above tables they are taken as above low water of spring 
tides as adopted for the Admiralty datum or 9 feet below the Old Dock 
sill. The calculated tides are reduced from Holden’s Tide Tables : these 
appear to give the expected height less than it actually is, as 78 per cent.
