Dissection of the Eye of the Streaked Bass. 



Cuvier states that, " in a great number of fishes, there is a falcl-' 

 form ligament which passes through a sHt in the retina, and pene- 

 trates the vitreous humor." " It contains blood vessels and nerves 

 and is attached to the capsule of the crystalline at its inferior surface, 

 sometimes by a simple elevation or by a fold a little more opaque ; 

 at other times by means of a grain or tubercle, transparent and hard- 

 er than the vitreous humor in which it is placed." Cuvier has as- 

 cribed no function to what is described. Jurin has named it the 

 ganghon of the crystalline. I considered it the expansion of a nerve 

 before closely examining its fibrous structure and its connexions.
