The diseases of the genital The diseases of the genital organs of domestic animals diseasesofgenita01will Year: 1921 86 Diseases of the Genital Organs amined in order to arrive at a reliable diagnosis. The vulva and vagina then need to be forcibly dilated. This is best done with the hand. After lubricating with warm oil, fat, or emulsion of elm bark, the fingers should be formed in a cone and, under gradual and firm pressure, the vulva slowly di- lated. In extreme cases the dilation may require an hour or two, or may demand repeated efforts on successive days. Any intelligent helper may, under proper instruction and caution, undertake the work, but it must not be unduly rushed. In some extreme cases I have inserted the uterine forceps into the vagina without inserting my hand, directing it on the median line, from side to side, inclined very slightly Fig. 38—Bischoff's Vaginal Dilator. downward, to the end of the vagina. Opening the forceps moderately and pressing them forward against the cervical end of the vagina, closing and locking them, and then apply- ing gentle traction, I have occasionally been able to draw the vaginal portion of the cervix back to the vulva, where it could be palpated by inserting one or two fingers and even- tually secured by guiding the second pair of forceps to the part by palpation. With both forceps applied to the cervix, the vagina may be visually inspected and the cervical canal and uterine cavity examined instrumentally. In some heifers, the vulva is constricted by the presence of a small band of connective tissue or aponeurosis, located about one-half inch from the margin of the lips, just beneath the vulvar mucosa. When vulvar dilation is attempted, the veterinarian encounters this firm, small, cord-like structure, which under the force employed cuts into his hand. I have observed this in one family of Holstein heifers, the members of which were unusually large and rugged, where the vulvae
