the lines of the cement substance of the endothelial cells in 
this preparation. We find the Membrana Descemeti in this 
case covered with a more or less granulated violet coloured 
substance, in which clear nuclei, some ovoid, some constricted, 
are inlaid at nearly regular intervals. Only here and there 
can we see between the nuclei pale contours, by means of 
which aree of more or less polyhedral shape are delimited. 
Corresponding to these contours run our dark, varicose, 
finest nerve-fibres. In some of them dichotomous division 
can be seen. ‘They withdraw themselves, however, com- 
pletely after a short course from our view. I may once again 
mention that we have here to do with fibres which can be 
traced to the fibres of the third order lying beneath (that is, 
deeper in the substance of the cornea than) the Memérana 
Descemeti.
