page 9 note * For when n = I, Ay n-1 becomes Ay o which is equal to unity, whatever the value of Ay may be.

page 10 note * This is a decreasing series in geometrical progression, whose common ratio is Ay. The rule for summing such series is to be found in all elementary works on Algebra. It is as follows:—Multiply the last term by the common ratio; subtract the product from the first term; and divide the remainder by the excess of unity over the common ratio.
