584 BULBUS OCULI 



If the lens body is compressed between the finger and thumb, it will 

 be noted that the outer portion or cortical part is soft, whilst the central 

 part or micleus is distinctly firmer. When the lens is hardened in alcohol 

 it can easily be proved that it is composed of numerous concentrically 

 arranged laminae. 



Chambers of the Eyeball. The anterior chamber of the 

 eyeball is the space between the cornea anteriorly, and the 

 iris and central part of the lens posteriorly. At the irido- 

 corneal angle it is bounded by the ligamentum pectinatum 

 iridis, and there the aqueous humour which fills this chamber 

 finds access to the spatia anguli iridis. 



The posterior chamber is a circular space or interval which 

 is bounded anteriorly by the posterior surface of the iris, and 

 posteriorly by the circumferential part of the anterior face of 

 the lens. Externally, this space is closed by the thick anterior 

 projecting ends of the ciliary processes. It also is filled with 

 aqueous humour.
