Schoppler(26) and Liertz(l7) consider the antecsecal position 
as very rare. 
We found Turner’s (34) classification of the topography of the 
appendix the most varied and complete in details. He gives the 
following types : 
Appendix lies free in the abdominal cavity. 
Cases. 
Hangs down in the pelvis proper 51 
Lies across the psoas toward the promontorium 20 
Lies free on the musculus iliacus or psoas 6 
Runs parallel to the lateral surface of the colon 2 
Lies in the central abdominal region, under the right part 
of the colon transversum 2 
Lies under the sigmoid flexure in the right iliac region 1 
Total 82 
Appendix lies behind the initial part of the colon ascendens between this 
and the posterior abdominal wall or iliac wall. 
Cases. 
Lies rolled up behind the ileo-cascal junction 4 
Lies behind the caecum bent into the fossa subcaecalis 5 
Runs along the posterior or the posteromedial surface of 
the colon upward 6 
Runs the same way but completely extraperitoneal 2 
Same as the next preceding but only partially extra- 
peritoneal 4 
Lies beyond the caecum which has previously turned up 
and backward ? 
From the above different classifications, we can deduce that 
the range of positions in which the adult appendix may be 
found is indeed great. If we further consider the pathologic 
immobilizations which may affect it, we can conclude that to 
set a definite position for the appendix is next to impossible. 
There are even cases in which the topographic variability of 
the appendix has gone beyond the confines of the abdominal 
cavity, when it was found included either in inguinal, or 
femoral, or other types of hernial protrusions. 
It seems, however, the consensus of opinion that, among the 
more frequent positions, the “pelvic type” is the most commonly 
encountered and the “antecsecal” the most rare. In children, 
especially in those of tender age, the difficulties of classifying 
positions become more apparent for the reason that we must 
consider, in addition, the mobility and the descent of the csecum. 
In studying the position of the appendix we were able to 
find topographic records of thirty-five adult cases and of
