Dear Dr. Frederickson, 
I am willing to support the new III-O section of the NIH guidelines 
(Federal Register 44 (1979) p. 69218). I think that the Rowe - Campbell 
exception would probably be better, but the new guideline is workable and 
should be implemented. 
Sincerely yours, 
Professor in the Departments of 
Microbiology and Biophysics/ 
Theoretical Biology and Chairman 
Interdepartmental Committee on 
Virology
