268 STUDY OF PIG EMBRYOS. 



The cells are much more closely compacted in this portion of the anlage than in 

 the sympathetic, and they are further distinguished by having nuclei which stain 

 much less deeply. The cords of cells, here seen, develop into the cortex of the 

 adult organ. The fate of the medulla or sympathetic portion of the suprarenal 

 in man is not known. The section passes through the side of the allantois, and, 

 therefore, shows only one of the lateral arteries, ^//. ar, but the allantois still bears 

 a number of degenerating mesothelial villi (compare page 222). At the pelvic 

 end of the abdomen a small bit of the Wolffian body, W . b, is displayed.
