Ings are supported and heldtogether by fine areolar tis-sue; but, besides this, numer-ous incomplete, transverse, fibrous partitions are inter-posed between larger massesof the coils, which ha^sebeen named the loies of theepididymis. The canal ofthe epididymis is, at itscommencement, about J^thof an inch in diameter, butdiminishing as it proceedstowards the globus minor, it is about yVth of an inch, after which it again. THE VAS DEFEEENS. 693 increases in size, and becomes less deeply convoluted as it approaches the vasdeferens. Its coats, which are at first thin, become thicker in its progress. The vasa eflferentia and the tube of the epididymis are provided witha considerable amount of plain muscular fibres in their wall. Theepithehal lining cells are columnar or prismatic in form and are ciliated, the cilia being long, and causing by their movement a current in theoutward du-ection. In the epididymis the cells are greatly elongated, inthe vasa efferentia they are shorter ; in the lower part of the epididymisthe cilia disappear. Between the fixed ends of the columnar ceUs othersmaller cells are met with. The vas deferens (fig. 598, h), or excretory duct of the testis, formsthe continuation upwards of the convoluted canal of the epididymis. Itcommences at the lower end of the epididymis, and, at first rather tortuousbut afterwards becoming straight, it ascends upon the i
