231. An enlarged model of the human eye, represented 

 in an inverted position in a part of its orbit ; the muscles 

 and nerves have their names attached to them ; for con- 

 venience the corresponding English terms are subjoined. 

 Made by Montaudon (late Dr. Aiizoux), Paris, 



E. 10. 1881. 



The external rectus muscle can be removed to show the nerves 

 which pass into the orbit between its two heads of origin. By 

 undoing a hook on the inner side of the sclerotic coat the ante- 

 rior part of this, along with the cornea, swings upon a hinge 

 revealing the choroid, which can be removed, drawing out the 

 optic nerve along with it. This with the nerve can be taken 

 out of the choroid, and the crystalline lens removed from a de- 

 pression in its anterior surface. Upon the vitreous body is the 

 retina, and an attempt has been made to show the various layers 

 of which this is composed.
