Observations have been made 1570 m (water equivalent) underground with an 8000 metric ton water Cherenkov detector. During a live time of 132 days, events consistent with the decay modes p..--> mu../sup +/K/sup 0/ and n..--> nu..K/sup 0/ were searched for in a fiducial mass of 3300 metric tons. It is concluded that the limit on the lifetime for bound plus free protons divided by the ..mu../sup +/K/sup 0/ branching ratio is tau/B>2.6 x 10/sup 31/ yr. For bound neutrons decaying into ..nu..K/sup 0/ the limit is tau/B>0.8 x 10/sup 31/ yr (90% confidence level).
