Note. — Removing the entire corneal portion of any of the forms was always accompanied by the 

 removal of part of the optic ganglion. In many cases as much as half of it. It frequently resulted 

 that all of the corneal portion subsequently degenerated after a part of it had been removed, and it 

 also frequently happened that the removal of the entire corneal portion resulted in the loss of the 

 whole eye stalk, consequently the above table can be used only as a very general indication of the 

 character of the operation.
