We have applied the beam-foil--laser (BFL) method to determine the lifetime of the 2{ital p}3{ital s} {sup 1}{ital P}{degree} level in O III. The result ({tau}=0.17{plus minus}0.01 ns) is in good agreement with most of the theoretical predictions but significantly shorter than the two beam-foil lifetime values reported previously. The oscillator strengths of the 2{ital p}{sup 2} {sup 1}{ital D}--2{ital p}3{ital s} {sup 1}{ital P}{degree} transition deduced from the present lifetime result in O III and from the very recently reported BFL lifetime in N II confirm the {ital f}-value trend along the carbon sequence calculated by Fawcett (At. Data Nucl. Data Tables 37, 411 (1987)).
