Dear Colleages: Does anyone have the latest e-mail address for Dr. Bruce G. Hatcher. I've tried hatcher at caribsurf.com and hatcher_b at col.barbet.net and bhatcher at ac.dal.ca They are all sent back as unknown addresses. Sorry to bother you all, but I have urgent business. Thanks. Sincerely, Charles Birkeland birkelan at uog9.uog.edu
