Two measurements of the ..beta.. spectrum of /sup 35/S have been made using a windowless Si(Li) detector. The data show a clear threshold anomaly at Q-17 keV which is consistent with the emission of a 16.9 +- 0.4 keV neutrino with a mixing probability of (0.73 +- 0.09 +- 0.06)%. All values of mixing probability <0.26% are rejected at the 99% confidence level.
