QUERIES AS TO THE HUMAN ANKLE-JOINT AND THE PERONEUS 
TERTIUS. By Burr G. WILDER. Cornell University. 
Has a rudiment of the peroneus tertius been recognized outside the 
human species? What are the latest statistics as to its presence in the 
several races of man? The conditions that permit apposition of the 
soles of the feet in climbing or for prehension are obviously useful with 
arboreal forms; but with man at his present stage of evolution do they 
confer any advantage commensurate with the disadvantage of the lability 
to sprain the ankle with inversion of the sole? If not, must not the 
existence of these conditions be regarded as purely phylogenetic rather 
than teleologic. Referring to the address of C. 8. Minot as president of 
the American Association for the Advancement of Science, 1902 
(Sctence, July 4, 1902), if the remarks on p. 5 as to the preservation of 
“only such structures and functions as are useful or have a teleological 
value” apply also to conditions as determined by structures, then either 
the designated conditions of the human ankle have a present use that is 
not apparent, or else they constitute an exception to the rule.
