Salve Regina University, Newport, Rhode Island
August 21-26, 1994	
David J. Des Marais, Chairman; Gerald F. Joyce, Vice Chairman

This meeting addresses several aspects of origin of life studies, including the
early history and environment of earth, prebiotic chemistry, and the geologic
and molecular biological record of early evolution.  A session on early Mars is
also included!  A single fee ($465., if paid before July 31) covers
registration, room and board for the entire meeting.  To obtain a registration
form please send a request to the Gordon Research Conference Office (tel.:
401-783-4011, FAX: 401-783-3372) or to D. Des Marais (tel. 415-604-3220, FAX:
