Abstract: Necessary and sufficient conditions are given that all solutions of $ {x^{(n)}} + f(t,x,x', \cdots ,{x^{(n - 2)}}) = 0$ are oscillatory for n even and are oscillatory or tend monotonically to zero as $ t \to \infty $ for n odd. The results generalize recent results of J. S. W. Wong and G. H. Ryder and D. V. V. Wend.
