ENUCLEATION OF THE ORBITAL 

 CONTENTS 



THE eyes one procures from a butcher or a 

 slaughter house will always have the extrinsic 

 tissues so badly cut and torn that identification 

 of the various parts and their relations is 

 impossible. Therefore, it is best to supply 

 one's self with the head of an animal, such as 

 a sheep or a calf, and dissect an eye with all 

 its extrinsic tissues intact. For this dissec- 

 tion, a hammer and a, chisel are necessary in 

 addition to the tools needed for doing the 

 previous dissections. 



Using the left orbit, begin the dissection by 

 making an incision directly over the supra- 

 orbital ridge, extending from over the inner 

 to the outer canthus. At the middle of that line, 

 make an incision, and cut at right angles up- 

 ward to the top of the head. Next make a cut 

 below the eye, extending from the outer to 

 the inner canthus. (Fig. 47.) Loosen the skin
