Here the several coefficients are ultimately given in terms of the before-mentioned
quantities A\ B 1 , C\ D i , E\ G\ H', L l , S\ T 1 (functions of a, a), and their differential
coefficients in regard to a

as follows:—we have Leverrier, pp. 299—330, a list of functions (1), (2), ...(154) of the
form (1) = \K i , (2) = — 2h 2 K i + Kf + Kf (3) = — 2i 2 K { + Kf + Kf, &c., involving i, h, and
K l and its derived functions Kf, Kf &c. The coefficients of the several cosines are
given by means of the functions in question, thus, first coefficient, above denoted as
(1)*(1 ... 20), is
= (1Y + (2) f a e) + (3)* (*✓).•• + W V e
where (l) i = (l), (2^ = (2) ... writing in the functions (1), (2) ... (10), h = i, and K^A 1 :
(ll) i = (l), (12y = (2), &c., writing h = i and K i = — E i ,
(20^ = (1), writing h = i and K l = — H l ,
and so on for the various component coefficients (1)*, (2) 4 ... (469) f .
But the resulting expressions, for the several integer values i = —10 to +10, are
worked out in the Addition II. {Numerical Tables for the Calculation of the Coefficients
of the Development of the Disturbing Function), pp. 358—383. And this Addition
contains also, indicated by the letters 8 and A respectively, the expressions of the
