AUSTRALIAN CYSTIC FIBROSIS ASSOCIATION Registered as a Charity in Queensland Patron: Please address all Dame Annabelle Rankin, D.B.E. Cro Bn 3 ° -P.O. Box 36 Chairman of Medical Committee: Resbane *e Professor T. J. Rendle-Short Queensland Australia. 19th November, 1967. Professor Joshua Lederberg, Stanford University, Palo Alto, California. USA. Dear Professor Lederberg, It was with very great interest indeed that I read recently, in the Brisbane press, a report of an address you gave at a Symposium on Genetics. I am sure you will understand my interest because you would understand the implications of the name of our Association. Part of the report read: "Professor Lederberg outlined two types of genetic intervention that he believes ‘technically poss- ible' within ‘a few years'. One is the use of special viruses to introduce new genes into the victims of inherited diseases." This seems to me (and I am neither a Medical Practitioner nor a scientist) to provide great hope for the children, and their parents, who suffer from cystic fibrosis. I wonder would you please be kind enough to elaborate a little on this and give us some more details? * One of our important services to our Members, and indeed to quite a number of Australian Doctors, is a periodical Newsletter giving news on the latest developments in treatment of, and research into, cystic fibrosis. Anything you could tell us about your work would be read with the most avid interest, I can assure you. Thanking you in anticipation, and with very best wishes to you and your co-workers, (PETER LAWTON) President.
