THE INTERIOR OF THE EYE 



FOR the study of the interior of the eye and 

 its contents in situ either a fresh or a har- 

 dened eye will do; a hardened eye is prefer- 

 able. In the dissection for isolating the hya- 

 loid membrane, vitreous, lens, and other parts, 

 the anterior and posterior halves of the evacu- 

 ated eye may be separated entirely, and each 

 half studied. However, the choroid and the 

 retina will be more or less mutilated, and the 

 vitreous and other parts will be removed. The 

 absence of these parts will prevent one from 

 receiving a definite idea of their anatomical 

 relationships. Therefore, it is better to work 

 with an entire and complete eye. 



Remove all the muscles and fatty tissues 

 from the outside of the globe; then cut it in 

 half through the equator, thus dividing it into 

 an anterior and a posterior half. The cutting 

 of the sclerotic, as well as the underlying tis- 

 sues and the vitreous, should be done with the
