Dear Mr. Althen: 
This is to confirm the understanding we had when we left the 
Court on Friday, January 13, 1978, that you will, as soon as 
possible, advise me of the source of the information relating 
to the European experiments involving Risk Assessment Studies, 
and any other details that you have concerning those experiments. 
As you can see from the enclosed pleading, time is quite important. 
Very truly yours.
