into the abdomen after division of all constricting bands on the exterior 

 of the neck, the sac of the peritoneum is to be opened ; and a director 

 having been introduced through the constriction, a cut is made horizontally 

 inwards for the extent of one or two lines. The several vessels that may 

 be wounded in attempting to relieve the deep stricture are enumerated at 

 page 429. 



SCARPA'S TRIANGULAR SPACE. 



This hollow is situate at the upper part of the thigh, and lies beneath 

 the depression observable near Poupart's ligament. It corresponds with 

 the axilla in the upper limb. 



Dissection (fig. 195). The space will appear on removing the fascia 

 lata near Poupart's ligament. The muscular boundaries on the sides may 

 be first dissected, and the muscle on the outer side (sartorius) should be 

 fixed in place with stitches. Afterwards, the remains of the crural shea',h

are to be taken away; and the femoral vessals are to be followed down- 

 wards as far as the sartorius muscle. On the outer side of the vesse's 

 clean the divisions of the anterior crural nerve, together with the branch( s 

 of an artery (profunda) which are buried in the fat. In removing the fat 

 from beneath the femoral artery, the student is to look for one or two small 

 nerves to the pectineus muscle. 



This inter muscular space (fig. 195) contains the trunks of the blood- 

 vessels of the thigh, and the anterior crural nerve, with lymphatics and
