A, longitudinal view of the fibres of the lens from the ox, showing the serrated edges. B, 

 transverse section of the fibres of the lens from the human eye. C, longitudinal view 

 of a few of the fibres from the equatorial region of the human lens. Most of the fibres

 zone ' ; at 2, the flattened sides of two fibres are seen. (A and B from Kolliker ; C
