Copy of letter to G.B. Airy

Reply to G.B.A. 29 Mar. 1886. Confirms he will be happy to take on publication of Lunar Theory if necessary. Suggests more decimal places and more equations needed to eliminate inequalities of long period in the theory.

Adams, John Couch (1819-1892) astronomer

Copy of letter to G.B. Airy

Agrees to take on G.B.A's Numerical Lunar Theory if G.B.A. unable to bring it to press himself. Refers to J.C.A. to G.B.A. of 7 Jun.1883, and has further information to add on the causes of inaccuracy in the numerical coefficients.

Adams, John Couch (1819-1892) astronomer

Copy of letter to G.B. Airy

Has been checking errors in G.B.A's Numerical Lunar Theory: cause is Delaunay's coefficients of parallax. Explains why.

Adams, John Couch (1819-1892) astronomer

Copy of letter to G.B. Airy

Further to previous explanation, which was evidently too brief. Detailed explanation of mathematics for G.B.A's Numerical Lunar Theory?

Adams, John Couch (1819-1892) astronomer

Copy of letter to G.B. Airy

Can think of no sensible way of reducing the length of the Greenwich Observations. Suggests modifications for G.B.A's Numerical Lunar Theory.

Adams, John Couch (1819-1892) astronomer

Autograph letter signed to J.C. Adams

Looks forward to seeing JCA at RAS; hopes he will have good influence on the meeting as the previous one was acrimonious, over Sadler. Airy may be present. Further action to be taken.
