	Mark is right, there are three cycles of the moon all between
18 and 19 years. Thank you Mark for looking it up. I believe, in 
retrospect, that the confusion I observed is between the 18.61
and 19 year cycles.
	In particular I recommend the book "Echos of Ancient Skies"
as a book that gets these things mixed up.
	At present I am trying to imagine how there could be eclipse
cycles of both 18 years 6 1/3 days, and 19 years no days, at the same
time, but it has to be possible doesn't it.
