Oscillation theorems for the damped elliptic differential equation of second order $\sum_{i, j=1}^{N}D_i[\,a_{ij}(x)D_jy\,]+\sum_{i=1}^{N}b_i(x)D_iy+c(x,y)=0$ ¶ are obtained. The results are extensions of averaging techniques due to Coles and Kamenev, and include earlier known results in literature.
