Layers of Cortical Substance, the fibres do not always closely fit into one another, but are boundtogether by a cement substance, a semi-fluid albuminous material. The cement substance not only binds together adjacent fibrils ofthe lens, but joins the sectors into which the whole mass is non-symmetrical stellate figures thus formed show on both theanterior and posterior surfaces of the lens. The lens star alwayshas three, but may have as many as six or more rays. When onelooks at a distant street lamp, the rays of light that appear about the ANATOMY (GROSS) OF THE HUMAN EYE 381 central part of the flame are generally the result of unequal refrac-tion of the light by the various sectors into which the human crystal-line lens is divided. This is true even of normal ej^es. 2 1 2 1
