eseminal vessels, as will be explained by andby. These seminiferous ducts in the testicleare only about one two-hundreth part of aninch in diameter, and when unraveled anddrawn out are nearly a mile long!Let us look for a minute at the wonderful complexity of the pro-creative machinery of man. Along the track of the descent of thetesticle on each side of the body, there passes down what is calleda spermatic cord, which consists of an artery and veins and lymphat-ic vessels and nerves. (See 8 in Fig. 139.) The artery is about the sizeof a crows quill. This conveys to the testicle the blood from whichthe gland with all its peculiar mechanism secretes and generates thevital elements of the semen. As before remarked, many imaginethat in coition, at the climax of excitement, the testicles inject thesemen directly up into and through the urethra. This is not so atall. As the testicular glands make their secretions, they pass themup through a canal called the vas deferens on each side. These

They ascend with the spermatic cord till theyenter the cavity of the abdomen, when they curve over each side ofthe bladder and bend down and connect with the seminal vessels.(Pause a few moments andlook over Fig. 139 with its ex-planations.) Instead thereforeof the testicles participatingat all in the sexual act, theyare comparatively at rest, andat the climax of amativeexcitement, their secretionswhich have been accumulatedin the spermatic vessels, arepropelled outward by whatare called ejaculatory ducts,and passing the prostate andCowpers glands are mixedwith the secretions of these,which contributions add con-siderably to the volume of thesemen. Propelled by the ejacu-latory ducts and the simultane-ous spasmodic contractions ofthe urethra, the
