We find the greatest value p and least value q such that the double inequality L (p) (a, b) < T(a, b) < L (q) (a, b) holds for all a, b > 0 with a not equal b, and give a new upper bound for the complete elliptic integral of the second kind. Here and L (p) (a, b) = (a (p+1) + b (p+1))/(a (p) + b (p) ) denote the Toader and p-th Lehmer means of two positive numbers a and b, respectively.
