The more numerous convolutions and the aggre-gation of the coni vasculosi at the upper end of the organ constitutethe globus major; the continuation of the convolutions downwards isthe body; and the smaller number of convolutions of the single tubeat the lower extremity, the globus minor. The tubuli are connectedtogether by a very delicate areolar tissue, and are enclosed by thetunica vaginalis. A small convoluted duct, of variable length, is generally connectedwith the duct of the epididymis immediately before the commence-ment of the vas deferens. This is the vasculum aherrans of Haller;it is attached to the epididymis by the areolar tissue in which thatbody is enveloped. Sometimes it becomes dilated towards its extremity,but more frequently retains the same diameter throughout. The Vas deferens may be traced upwards in the course of the semi-nal fluid, from the globus minor of the epidi
