Morse Code 

        This webpage concerns the morse code of the Kryptos puzzle.  Many thanks 
to Eric Hall for his insights and help on this presentation. 
Typing out the Morse code without spaces between individual letters reveals that 
the entire code is a series of palindromic repeats. While the dits and dots of 
repeats are identical in both directions, the words they form are not. In order 
for the message to be read in the reverse direction, substitutions must be made. 
Inspection of the Morse code alphabet yields a set of letters that is a mirror 
image of itself, one that is a mirror image of another letter, and another that 
is not a mirror image of any other letter.  Using these characteristics, one can 
build a table in order to to decipher the reverse code.

This last example is not precise, as it takes more than just letter mirroring:
