HISTOLOGY OF RETINA. 



489 



tain fibres run vertically through the retina from the inner 

 to the outer limiting membrane; they are known as the 

 radial fibres of Midler and give off lateral branches, which 

 are especially numerous in the molecular layers.

 1, in contact with the hyaloid memb'ane, to its outer, 10, in contact with the 

 choroid. 1, internal limiting membrane; 2, nerve fibre layer; 3, nerve-cell 

 layer; 4, Inner molecular layer; 5, inner granular layer; 6, outer molecular 

 layer; 7, outer granular layer; 8, external limiting membrane; 9, rod and cone 

 layer; 10, pigment-cell layer. 



On account of the way in which the supporting and essen- 

 tial parts are interwoven in the retina it is not easy to track
