Asks JH to send the astronomical part of her manuscript [Mechanism of the Heavens] by Mr. Richards on Thursday.
Used a counter spell to keep the moon at a 'due distance.' Her previous computations were careless. Asks JH to return part of her manuscript [Mechanism of the Heavens] for corrections.
Wants to use method of indeterminate coefficients to integrate the differential equations of the planets' perturbations. [Originally written to W. Fairfax.]
Needs advice on integrating equations. Praises JH's book [Prelim. Discourse]. Says James Mackintosh and [Henry] Hallam also praise it. Note from William Somerville, which needs a reply, is enclosed.
Explains to MS P. S. Laplace's method of indeterminate coefficients in mathematics. Thanks MS for her praise of his book [Prelim. Discourse], which JH values more highly than newspaper reviews.
Sends preliminary observations that will be prefixed to her book [Mechanism of the Heavens]. Wants JH to make any criticisms of it before it is published.
Returns proofs and sends a few remarks concerning them. Discusses difficulty of measuring Eta Coronae. Anxious to see her [Mechanism of the Heavens]. Has another daughter [Isabella].
