ring* of the membrane of Descemet the process of the 

 iris is directly continuous (fig. 393, d),f as are also the most 

 anterior trabeculse of the plexus filling the canal of Fontana 

 (fig. 393, /); in short, the so-called ligamentum pectinatum 

 iridis of Hueck. The mode of transition in the Ox and Pig- 

 is the same as in Man. In the Dog, on the other hand, there 

 is no marginal ring of the membrane of Descemet, and the 

 process of the iris is developed directly from the fibrous 

 cones, forming with their bases a wavy outline to the mem- 

 brane of Descemet. J 



The endothelium of the membrane of Descemet is uninter- 

 ruptedly continuous with the endothelium of the process of 

 the iris, and also with that of the most anterior trabeculae of 

 the canal of Fontana (e r e], and through this, lastly, with that 

 of the anterior surface of the iris (e" e", fig. 393) .
