and obviating the bad effects which concussion would have been likely 

 to produce in the tarsus had it been one rigid structure. 



Directions.-^The ligaments of the tarsus are both numerous and com- 

 plicated, and the best order of their dissection is that in which they are 

 hereafter described. Since one set of ligaments must be removed in

order to expose the following set, the dissector should not proceed with

TiBio-TARSAL LiGAMENTS. — These are four in number, viz., two lateral, 

 an anterior, and a posterior. 



The External Lateral Ligament consists of a superficial and a deep 

 fasciculus, which cross one another like the legs of the letter X. The 

 superficial division, which is the larger of the two, is fixed superiorly to 

 the posterior part of the external malleolus of the tibia, while inferiorly
