Laminar free convection flow of a power law fluid from a horizontal plate has been considered. Using Karmana-Pohlhausen integral method it has been shown that similarity solutions exist if n=1 and if the difference between the wall temperature and ambient fluid temperature varies as the cube root of the distance along the horizontal plate. The velocity and temperature distributions are obtained for different values of flow index n and parameter R1. It has been observed that increase in the parameter R1 leads to decrease in the boundary layer thickness and temperature. The velocity rate of heat transfer and shear stress at wall increases as the parameter R1 increases in the range O .5 s R1 s 1.5. The velocity at a given point within a thin liquid layer increases with the increase in the value of a vertical distance yb, but outside this layer the velocity decreases.
