Dear Josh:

As you arc aware, the issuc of cloning has come again into the public spotlight by the perhaps
inevitable effort of an individual to clone human bcings. This action and the publicity it has
engendered has inspired calls for legislation regulating “cloning” by the Congress and the
Administration. Jt is hoped that Congress would accept the caution of the National Bioethics
Advisory Commission that any Icgislation be carcfully written so as not to interfere with other
important areas of scientific research.

The real danger of some bills that have already been proposed is that it they scach beyond the
narrow illegalization of cloning human beings to inadvertently or intentionally limit important
biomedical research.

Yo prevent this outcome, 1 am requesting your endorsement and that of other fellow Nobelists of
the attached letter. If you are willing to co-sign, please complete and return the enclosed form as
soon as possible but no later than Monday, February 9 by 12 noon Eastern time, to the American
Society for Cell Biology.

Thank you very much for your imuncdiate consideration.

Sincerely yours,

pus
