The American journal of anatomy . in the rabbit, or in other mammals in whichthe dorsal margin of the intestine is thickened from the first. Butin pig embryos the parallelism is strikingly shown. Both thedorsal and ventral pancreases pass through a transient pairedstage; both become median structures which are more or lessbi-lobed, and both develop predominantly on the right side. The ventral pancreas in pig embryos may extend wholly towardthe right side, as seen in figs. 4 and 6, from embryos of 10 to 12 mm. respectively. In the younger specimen, theupper part of the pancreas is subdivided by a groove into left-anterior and right-posterior divisions. If these lobes are due tothe fusion of the primary buds, it is evident that the right budhas produced the greater part of the ventral pancreas. In theolder specimen (fig. 6), there is no trace of a left lobe. But inother cases, as shown in figs. 5 and 7, from embryos of mm. and10 to 12 mm. respectively, both lobes are well defined; in both P-l- L. d.
