In this paper, by using the Discharging Method, we show that any graph with maximum degree A 1>8 that is embeddable in a surface 2~ of characteristic X(Z)>~0 is class one and any graph with maximum degree A>~9 that is embeddable in a surface Z of characteristic X(Z)=-1 is class one. For surfaces of
