PLATE 2, Same Embryo as Plate 1. Reconstruction of venous system of left 
side, mesial view from the right. The aorta is represented as transparent, with 
the cardinal shining through. The white interrupted line gives the outline of the 
left Wolffian body. The caudal part of the embryo is somewhat twisted, so the 
small vessels entering the subeardinal caudal to the mesenteric artery are lateral 
(mesonephric) not ventral tributaries. > 19.0.
