bones, parts of the short flexors of the great and little 

 toes, the adductor pollicis, and transversus pedis will 

 be found cut in the flap. The tendons of the long 



flexors of the digits 

 and great toes, the 

 peroneus longus, 

 and the plantar 

 vessels and nerves 

 are also divided 

 (Fig. 58).

 the tarso-metatarsal 

 line of joints. In 

 the dorsal flap the 

 same structures are 

 divided as are cut 

 in the correspond- 

 ing flap in Clio- 

 part's amputation.

 be noted that the articulations between the three outer 

 metatarsals and the corresponding tarsal bones form a 

 line sufficiently straight to be traversed by the knife 

 in one cut when once the blade has been introduced. 



The joint also between the first metatarsal and 

 internal cuneiform bones is in a straight line and 

 readily opened. The most difficult part of the dis-
