Each is about the size and shape of a small bean, and possesses a long slender duct which opens into the rima pudendi in the angle between the attached border of the labium minus and the vaginal opening. DEVELOPMENT OF THE UPJNO-GENITAL OPtGANS. The Ueino-genital Passages. General Account.—In tracing the developmental history of the urino-genital passages we may for convenience begin with an embryo of fifteen days old. About this time a duct, which runs in a longitudinal direction, and occupies a position on the lateral side of the protovertebi-al somites, begins to develop on each side of the body. With the exception of the anterior portion of the cloaca and the proximal part of the allantois, this duct, which has received the name of primary excretory or Wolffian duct, is the earliest formed structure from which, or in connexion with which, the parts of the adult urino-genital system arise. The Wolffian duct serves as the canal, or duct, for the primitive secretory organs— the pronephros and the mesonephros of the embryo. With the atrophy of these the duct suffers modification, yet both sexes in the adult possess structures which have their embryonic origin f
