twenty-nine foetuses from the fourth month to full term, twenty-three 

 or nearly 80% show the adhesion of the colon to the head of the 

 pancreas. The area on the anterior surface of the pancreas which is 

 adherent to the transverse colon is usually triangular in shape, the 

 base of the triangle being placed to the right, the apex to the left. 

 This apex corresponds to the point where the transverse mesocolon 

 begins, extending to the left along the anterior border of the body of
