This paper deals with the second order nonlinear neutral differential inequalities $(A_{ν})$ : ${(- 1)}^{ν} x (t) {z^{''} (t) + {(- 1)}^{ν} q (t) f (x (h (t)))} \leq 0,$ $t \geq t_{0} \geq 0 ...$

We present a new theorem on the differential inequality $u^{(m)} \leq w (u)$ . Next, we apply this result to obtain existence theorems for the equation $x^{(m)} = f (t, x)$ .
