We have written statements from most of the individuals who desire 
to make them. If they wish to abridge their comments, we will see that 
their full statements get into the record. 
MR. HUTT: Will those be distributed to us? 
DR. FREDRICKSON: They will when we get enough of them. 
DR. MC CARTHY: We have most of them Xeroxed now. 
DR. FREDRICKSON: They are in process. 
Now, I just must state the rules for this part of the proceedings, 
however. At the end of 9 minutes, should you go that far, those of you 
who are public presenters, I will hold up my hand, and at the end of 10 
minutes you really must come to a halt. VJe will then have approximately 
5 minutes for the committee to address questions or comment, for you to 
have colloquy with them if that is possible. 
With that preamble — and we will stop sometime before we hear all nine, 
I assure you, for coffee — I would like to call upon Dr. David Baltimore, 
who is from MIT; and while I hope that each of you who come forth will 
indicate something of the nature of your connection and interest in this 
particular problem, I will save Dr. Baltimore from reminding any of you 
who do not know it that he is a 1975 recipient of a Nobel Prize in Physi- 
ology and Medicine. Dr. Baltimore, your clock is starting. 
DR. BALTIMORE: Dr. Fredrickson, ladies and gentlemen. I was one of 
the original members of the National Academy of Sciences Committee on Re- 
combinant DNA Molecules, the committee that recommended a voluntary defer- 
ral of certain experiments. I was also on the organizing committee of 
the Asilomar conference, but since that time I have had no role in the 
formulation of the proposed guidelines, and have really come because I 
have an interest in these questions and an interest in seeing that this 
work goes forward under the safest possible circumstances. 
In this statement I want to deal with three aspects of the proposed 
guidelines. The first is whether they are an appropriate response to the 
hazard posed by recombinant DNA molecules. The second is whether the 
process that has led to the formulation of these guidelines has been a 
responsible process, and finally, I wish to emphasize how urgently the 
international scientific community and the public it serves needs these 
guidelines . 
Let me first deal with the question of whether they are an appropriate 
response to the hazards in recombinant DNA work. A precise answer to that 
question would involve a precise knowledge of the hazards involved, and as 
has been emphasized so often here, the hazards involved in recombinant DNA
