LENGTH OF THE APPENDIX 
Notwithstanding the fact that Berry, (l) in his detailed survey 
of one hundred cases, claimed that the length of the vermiform 
appendix is not so variable nor so long as textbooks would lead 
one to believe, yet the review of the literature on the subject 
has convinced us that the range of variation of this measure- 
ment is indeed great. Tables 2 and 3 give an idea of such 
variation :
