The upper, oblique end is thenapplied to the vulva, the longer side being posterior,and with the edge the posterior vaginal wall, is gentlypressed backwards ; the lower end at the same timeis so held that the instrument lies in the obstetricaxis of the pelvic outlet. In this way the ostiumvaginae is stretched until the short anterior side of thespeculum will slip past the vestibule without the useof force. The instrument is then pushed gently in-wards, the long side being directed behind the cervixinto the posterior fornix ; the cervix then liesexposed in the upper end of the speculum, and thevaginal walls are not seen.
