 ciliary muscle and lens whereby objects at different 

 distances are clearly seen. It depends upon the inhe- 

 rent elasticity of the lens, which when the ciliary 

 muscle ol an emmetropii eye 1- at rest is adapted to 

 the proper localization ..l' parallel rays of light, or of 



such rays a- proceed from an infinite distance, ..i t 1 



the horizon of the observer. Objects nearer, to be 

 . learly se< n, require a greater refracting power on the 

 part of the eye because tin rays from such objects ate 

 moil' divergent. This additional refracting power is 

 gained by an increased antero-posterior diameter of 



the lens, L, [illustration annexed) brought about by 

 the contraction of the ciliary muscle, .)/, which occa- 

 sions a loosening of the suspensory ligament and a 

 thickening of the lens by its own elasticity. A., Paraly-
