 inside of the thigh, where the femoral artery passes obliquely 

 across it. 



Plage and Mode of Bleeding. — Bleeding from the ears 

 or tail, as is commonly practiced, rarely extracts a quantity 

 of blood sufficient to do any good where bleeding is indicated. 

 To bleed from the eye-vein, the point of a knife is usually 

 inserted near the lower extremity of the pouch below the 

 eye, pressed down, and then a cut made inward toward the 

 middle of the face. Daubenton recommends bleeding from
