The references to testing flats using water as the reference surface are:

"A Flat Tester right Under Your Nose" by Richard Parker, ATM
Journal, Issue 17
-
18, pages 22 - 27.

"The Raleigh Water Test" by Ed Jones, Sky & Telescope, July
1990, Page 89

Any public library should be able to get you the S&T article, or you
can pay a little money and get it online at S&T's web site.  For the
ATMJ article, you will probably have to beg a copy from a fellow ATM that
had the good sense to subscribe.
