But, since the fluent is easily attainable by logram this and circular arches, which are series already computed, I shall now treat of that method. It is easy to perceive that the fluent of may be taken in this form, viz.-----r +:, 7 + / T, in which the, the coefficients A, B, and C, may be computed with great facility. But a better form for numerical calculation may be derived from Madam A%ncsi's Theorem in her Analytical Institutions, Book III. Sect. I. Art. 56; observing, first, that the indices of x, in the numerator of the fraction which she assumes, will always be an arithmetical progression decreasing by the constant difference m: And, feco-id'y, that when n (still using her notation isgreater than m, let m be taken from n as often as it may, which call p. times, and put the remainder, n--pm--r; then will y- XXn _-Bxr+um-zm+l__QxT+m-3m+i _Y)xr+um-4M+t + 8cC.

'---:, from the fluxion of which equation the values x"-+ a- of A, B, C, D, &c. will easily be found, and then no more remains to be done than to compute the fluent of the term Axxr: by the well known method of logarithms and circular arches. Now, by means of this equation we shall find /--Tt t0 be = r--1 3.. + T-, 7-; and since the correct fluent of =-266866 in the present case where x =2, or 1 1--x6 = 26 = 1122462.
