This paper presents a preliminary report of recent measurements of quasielastic electron- deuteron scattering. Data points were taken at a scattered-electron laboratory angle of 20 and for a range of four-momentum transfers from 7 to 70 F^-2. Three different measured quantities have been extracted from the data: (1) the ratio of electrons without a coincident proton to electrons with a coincidence, which it is hoped, after small corrections, is equal to the neutron-to-proton cross-section ratio; (2) the ratio of the total electron-deuteron "area method" quasielastic cross section to the elastic e-p cross section from hydrogen, which should equal (simga_n + sigma_p)/sigma_p; (3) the ratio of the electron-proton coincidence cross section from deuterium to the same e-p coincidence cross section from hydrogen using the "area method." The measurements were made in conjunction with elastic electron-proton cross-section measurements from hydrogen.
