274 THE ANATOMY OF THE HORSE. 



The Vitreous Humour occupies four-fifths of the interior of the 

 eyeball. It is globular in form, with a depression in front for 

 the lodgment of the lens. It is colourless, transparent, and of a 

 consistency like thin jelly. It is enveloped by a delicate capsule— 

 the hyaloid membrane, which is connected in front with the 

 suspensory ligament of the lens, and ends by joining the capsule 

 behind the lens. 



Structure. — The vitreous humour is composed of branched connective- 

 tissue corpuscles in a jelly-like matrix.
