VIII. THE MUSCLES OF THE LOWEK 

 EXTREMITY. 



To expose these, extend the median dorsal excision 

 through the integuments, to the very tip of the coccyx ; 

 join this by an extension of the median integumental 

 ventral incision. Next, join these two lines anteriorly 

 by a lateral division of the integuments, which above 

 passes immediately behind the point of the scapula. 

 Reflect the skin thus set free, and carefully remove it 

 as far as the ankle-joint. Here we meet with the 

 horny podotheca covering the tarso-metatarsus and toes. 

 This is best removed by lateral incisions and peeling 

 backwards and forwards both ways, being particularly 

 careful not to injure the tendons.
