These things I have found to fall out right at London for many years, and so I suppose they may in other places. If the difference be not so much between the Neap-tides and Spring-tides in other places, the Diameter must be divided into fewer parts.

As for the higest Tides to happen two or three dayes after the full Moon, I have not made much observation of it, and see little reason for it, but the time thereof agrees herewith. And high Spring-tides are not alwayes alike; this year I have not observed any. I should be glad to hear, how these rules hold in other places, that so this true time of the Tides may be more punctually known.

April 6. 1668.
