LESSON XXIX. 



THE EYE. 



1. Section of the anterior part of the eye of cat or 

 dog (Flemming's fluid). Observe 



The irregular connective-tissue of the sclerotic 

 passing into the lamellae of the cornea. The fan-like 

 bundles of fibres spreading from the junction of the 

 cornea and sclerotic, to the iris (ligamentum pectina- 

 tum), and to the choroid. Amongst the latter bundles 

 are some bands of unstriped muscle, the ciliary 

 muscle. 



The ciliary processes, forming a much folded mem- 

 brane. Note the two layers of cells, columnar to 

 cubical cells and pigment cells, continuous respectively 

 with the inner coat and with the pigment cells of the 

 retina. 



The hyaline suspensory ligament attached to and 

 projecting from the ciliary processes, and running to 

 the capsule of the lens. 



The passage of the layers i to ix of the retina ( 7) 

 to columnar epithelium at the ora serrata. 



The iris, consisting of, (a) a layer of pigment cells 

 (uvea) continuous with the pigment of the ciliary pro- 

 cesses, and so of the retina ; (6) a thin fibrous-looking 

 layer, forming the dilatator pupillae ; (c) a thick layer
