The Vermiform Appendix. — The average position of the root 

 •of the appendix was in the right lateral line at a distance 

 of 3 cm. below CD. (or 2 cm. above the level of the anterior 

 superior iliac spines). It is one inch directly below the point 

 where a line drawn from the anterior superior iliac spine to the 

 •umbilicus crosses the right lateral line. 



Alterations in level. — There were four cases in which the 

 root of the appendix was displaced upwards above the plane of 

 CD. In cases 12 and 23 it was carried up by a distended 

 caecum, which would have been obvious on palpation. In the 

 other cases, Nos. 17 and 18, there was a high cascum, associated 

 in case 18 with an ascending meso-colon, and having in case 

 17 very loose peritoneal attachments. In two of these cases 

 and in five others (Nos. 8, 19, 27, 33, and 38) the tail of 

 the appendix passed up above the level of CD. In cases 19,
