Minot. — Veins of the Wolffian bodies in the pig. 
PLATE 1. 
Fig. 1. Pig, 12.0 mm. Sagittal series 7, section 39. (Compare also series G, sec¬ 
tion 453.) Through the right Wolffian body. A short branch of 
the cardinal vein can be followed on the dorsal side of the Wolffian 
body in neighboring sections; see especially Section 24. X 28 
diains. 
Fig. 2. Same as above, but from section 51, to show the connection of the 
vena cava inferior with the right Wolffian body. The Wolffian 
tubules are not accurately drawn, and the small blood channels 
between them are omitted. The vena cava inferior shows no 
branches of any importance outside of the Wolffian body. In 
section 68, the vein conies very close to the dorsal aorta leaving 
only a very thin partition. X 28 diams. 
Fig. 3. Pig, 12.0 mm. Frontal series 6, section 423, passing through the 
entire length of the vena cava inferior. The section also illustrates 
the influence of this vein, developed upon the right side, in forcing 
the stomach to the left. X 13 diams. 
Fig. 4. Pig, 12.0 mm. Transverse series 5, section 705. Through the 
Wolffian bodies at the level of the connection with the vena cava 
inferior. X 17 diams. 
Fig. 5. Pig, 12.0 mm. Frontal series 6. Abdominal veins in frontal view, 
reconstructed from drawings of every tenth section, but the branches 
of the umbilical vein in the ventral part of the liver are entirely 
omitted. X 13 diams. 
Fig. 6. Pig, 12.0 mm. Frontal series 6, section 423. Part of the left Wolffian 
body to show the relation of the venous endothelium to the Wolf¬ 
fian tubules. X 267 diams.
