cornea cut radially into eight parts, spread out into the plasma 

 within twenty-four hours in an extension which was even larger 

 than their original area, though not in the same degree of rapidity

 that the whole endothelial surface was covered within twenty-four 

 hours by the epithelium spreading over the entire circumference 

 of the piece. When the moving borders met each other, move- 

 ment ceased. 



Some measurements are given in table 3.
