In tli>' i>s. tin' t riuinal tendon of the perforans does not receive any carpal band ; 

 this goes to the perforatus. Above the fetlock, it divides into two branches, one for <-a--h 



which, after trav.-r.-iuu' tlie perforatus, terminates behind the inferior fa- 



tin- third phalanx. There it is blended with tl.e plantar cushion.

d in the description of that ligament. This layer aris, s 



fr>ni the ai-oneurosis covering the flexor tendons in the nictn- 



! region: it descends on the heels, Ir.-hind and outside tlie 



dibits, ren.aiiis united to that of the other digit by an inter- 



;te fibrous faM'ia. and is ntlached to the enveloping sheath> 



of tlie tlexor tendons, as well as to the superior intcrdigital lijru-

which reach the pyramidal eminence of the third phalanx of the 



four digits. The tendon of the small external digit often gives
