Reply to J.C.A.'s of 29th. Comments on article in Mechanics Mag. Dec. 1846. Advises to wait for new observation of New Planet (Neptune) to measure its distance from sun, not to calculate. Thanks for further figures of position of planet. Does not favour Hansen's methods of calculation, nor LeVerrier's use of single observations. On the Lunar & planetary reductions calculated from Camb. Observatory
(See G.B.A. to J.C.A. 27 Mar.1851 for table of Saturn dated 1 Feb.1847).

Requests J.C.A. or someone appointed by him studies '8 Venus mean longitude - 13 Earth's mean longitude' in the Moon's motion, to settle who is right between Hansen and Delaunay. Will send cheque for Horrocks Memorial later. (See G.B.A. to J.C.A. 28th Oct. 1874).
