The second would be to license the — and I will probably not use the 
correct technical terminology — but the cutting enzyme, whatever that scien- 
tific word for it was, and the source of the foreign DNA — I hope I have 
got that one right — that is of concern to scientists. The agents that were 
described, for example, as CDC classes 3, 4, and 5, and make sure that 
anyone who was to purchase those for use in any kind of experimentation of 
this type would again be required to follow the NIH guidelines. 
Now, these are two possibilities or three possibilities I have thrown 
out. I don't see how any of us could possibly do more than begin a consid- 
eration of those today, and perhaps even that is not possible. 
What I am suggesting is that to keep the initiative in the scientific 
world rather than to allow it to escape, and to become overrun with regula- 
tion, that this issue must be addressed very realistically and very immedi- 
ately. And I would simply suggest, Don, that the best process should be put 
in motion as quickly as possible, so that the concerns of those of us who 
represent the citizenry at large can be reduced to the minimum level. 
Thank you. 
DR. FREDRICKSON: We will pause, Ms. Haygood, before we come to you 
because the mail has to be delivered. This is the only place in town where 
you can count on the mail. 
(Laughter. ) 
I would also comment in this hiatus, for the record, that the empty 
chair next to Mr. Hutt is that which was allotted to Mr. William Smith, an 
attorney for the Children's Defense Fund, and Mr. Smith was unable to be 
with us during this day-and-a-half meeting. 
I don't think that you are as interruptive as you think, and I believe 
we can go ahead and ask Ms. Haygood to comment, if she would not mind. 
MS. HAYGOOD: I have quite a number of specific comments arising out of 
this day-and-a-half meeting, so I — 
DR. FREDRICKSON: Ms. Haygood, would you like to use the podium? 
MS. HAYGOOD: I have a number of specific comments that arise out of 
this day-and-a-half meeting, but given that our time is running short, I 
think I will just hit a few highlights and submit the rest later. 
In the area of physical containment, my own personal experience as an 
itinerant student wandering from lab to lab leads me to conclude that PI and 
P2 cannot really be depended on for physical containment as it is generally 
practiced.
