The number of efferent ducts in about 10 animals examined by us was three to five. The efferent ducts have two parts: beginning at the testis, in the first part the ducts have a short, straight, then convoluted course and are surrounded directly by the fat body of the testis; in the second part the ducts are highly convoluted and Ductus epididymidis.

(X200.) are surrounded by a connective tissue capsule which becomes continuous with the capsule of the epididymis. The efferent ducts enter and form the first small segment in the caput of the epididymis. Our own observa- tions are in agreement with those of Benoit (6) and Young (98) who found that the efferent ducts unite into a single duct which is in continuity with the duct of the epididymis (Fig. 65). The lining of the efferent ducts is composed of alternating groups of tall and low columnar epithelial cells, which give the lumen a characteristic scalloped outline. The epithelial cells rest on a basement Please note that these images are extracted from scanned page images that may have been digitally enhanced for readability - coloration and appearance of these illustrations may not perfectly resemble the original Roscoe B.
