itear Kuy:

  Sorry to be so long in responding to your letter of 20 Aay. Tne
fact is I've been on a wrry-go-round reqarding definitions and was
awaiting resoiut ion of such before writ inq.

  As you prouavly ~riw I ad1 in favor of the substance of the Advisory
i;omaittee's new draft. I nave ~een involved witn varjous attempts to
::et sucti n definition in tne bills now wing considered. tf.%. 741r3, tile
3ost recent House version, atte.apts to do what tne Advisory Comittee
suggests, out tile wording is terribly garbled. rilere is already a
revision that  ill ~e proposed at tire inark-up (now postponed for tile
second time, until next S'uesday) and tnat is clear, wnile still con-
taining sone proalms. 1 nope to be in toucn with Zimersan tonorrow.
Clearly, if the narrower definition is in a bill that is passed, the
desired end dill be actiieved.

lhe current version of tne Senate oil1 (S. 1217) also has an

                  P'eruaps you could write to the

exclusion mt it is not narrowed by the ilnportant euKaryote - proaaryote
distinction (a COPY is enclosed).

tnc? muse version os the latest version of t~ie definition is not in
QY copy. ftie senate and iiouse Dills are nsrkedly different througnout.
L'tw denate oil1 v;ould set up a large bureaucracy, and would more

reasona~ln to my thinking.

best regards,
