Limits are set on B/sup 0/B-bar/sup 0/ mixing by use of dilepton events from UPSILON(4S) decay. On the assumption that the charged- and neutral-B semileptonic branching ratios are equal and that 41% of the B mesons from the UPSILON(4S) are neutral, a 90%-confidence-level upper limit of 24% is set on B/sup 0/B-bar/sup 0/ mixing. Limits are also given for the ratio of the lifetimes of neutral and charged B mesons. The 90%-confidence-level limits are 0.44
