Stuk 90 - Letter from John William Lubbock

4 pp.

St James's Place - William Stratford agrees with JWL in thinking it desirable to print the comparison of the London and [Rothine or St. Catherine] docks. JWL would like WW to view the tidal gage and clock at these docks. If the Royal Society decide to print his paper on the development of R, JWL would like to make some additions to enable him to take in the terms dependent on the inclination and also to extend his table to include terms not wanted in the lunar theory: 'This method of developing R is a very great and undisputed improvement in my Lunar Theory on account of the great facility with which in this the coefficients of r dR/dr are obtained from those of the coefficients of R...the new method diminishes the labour prodigiously and I could now do by its means in one day what took me weeks to get through. Besides the operations are so simple that the probability of error is almost annihilated' ['On the Theory of the Moon, and on the Perturbations of the Planets', 1833].
