asterisk (*) meansthat the singularities (modp) of r, and r2 are excluded and in the sum 1 lo (o f 0 (modp)) is to be interpreted as the unique integer w (modp) such that ow = 1 (modp)). Perel'muter has given conditions under which this sum is O(pf), thus generalizing the earlier deep work of Weil [4] and Carlitz and Uchiyama [2]. It is the purpose of this note to show that Perel'muter's work can be applied to estimate the character sum
