Stuk 86 - Letter from Thomas Gamlen Bunt

1 folded sheet

Bunt examined the Register of the Tide machine along the Avon and at Cumberland Basin. The latter is 'sufficiently correct' to deduce the empirical laws of the tides at the port of Bristol to WW's specifications. Bunt hopes 'to calculate and publish a Tide-Table for the ensuing year'. He gives a description of how he constructed diagrams of the moon's transit and parallax which he uses to produce tables for declination and parallax to help predict times of high water. He has not yet taken into account solar declination and parallax.
