Measurements of multihadron production in e/sup +/e/sup -/ annihilation at center-of-mass energies between 2.6 and 7.8 GeV are presented. Aside from the narrow resonances psi(3095) and psi(3684), the total hadronic cross section is found to be approximately 2.7 times the cross section for the production of muon pairs at c.m. energies below 3.7 GeV and 4.3 times the muon-pair cross section at c.m. energies above 5.5 GeV. Complicated structure is found at intermediate energies. Charged-particle multiplicities and inclusive momentum distributions are presented.
