with the corresponding tendon of the flexor sublimis to constitute 
the perforated tendons of that digit ; that going to the fifth digit 
is inserted by itself outside the deep flexor ; that going to the second 
digit is inserted singly on the inner side of the deep flexor tendon. 
The perforated tendon of the third digit is formed by the flexor sub- 
limis only (fig. 6, F..m.). The fleshy belly, which Meckel* de- 
scribes as investing the tendons of the sublimis at their origin, is 
doubtless our flexor accessorius manus. :

The flexor profundus and longus pollicis are distinct above, but 
united at the wrist, where they give origin to a very broad and strong 
tendon, which, dividing into four, forms the flat and strong perforating 
tendons of the four digits. The tendon to the index does not pass 
though a truly perforated tendon, but the tendons from the flexor 
brevis and flexor sublimis so cross each other as to produce the 
appearance and action of a normal perforated tendon (fig. 6, F. p. d. 
and F’. l. p.). Meckel+ appears to have confounded this muscle with 
the flexor sublimis. They are indeed very closely connected, but still 
able to be separated,
