Transit of Venus. Willing to use C.O. telescope to make observations. Has another which might be of use. Suggests techniques for getting most out of the event. Suggests that S.J.C. Dolland telescope might also be used.

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

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.

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.
