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. Schematic Eepresentation of the Course of Lens Fibres and the Arrangement ofLens Stars in the Foetus and Newborn. (Schwalbe.) The zonule of Zinn, or suspensory ligament of the lens, is a collec-tion of delicate fibres,* a few of which originate as far back as theora serrata; the majority spring from the valleys between the ciliary
