Mack objected before the district court that 
there is no further EIS discussion of the probable result 
of this experiment' -- which experiment is specifically cited 
in the EIS as an important unknown which has to be resolved. 
It is plainly unreasonable to demand detailed discussion of 
possible results in the area which is the specific experi- 
mental unknown. Scientists 1 Institute for Public Information 
v. AEC, 156 U.S.App.D.C. 395, 409, 481 F.2d 1079, 1093 (1973). 
Mack also objected that there were no alternative experiments 
discussed. As far as alternative experiments are concerned, 
the object is to find out what happens in this particular 
variety of recombinant DNA experiment, combining a virus, 
which affects only rodents, producing tumors under laboratory 
conditions, with a weakened laboratory bred bacteria. The 
intention is to see if the bacteria with the altered DNA will 
cause tumors in mice under the same special conditions as 
the virus caused tumors in mice. There is absolutely no 
intention to create a "biohazard," as Mack alleges. To the 
contrary, the district court specifically found that the 
experiment poses no substantial risk (Finding of Fact No. 11). 
The information from the experiment is needed to reassess the 
guidelines. It is difficult to understand how the information 
can be obtained without doing the experiment. Mack does not 
suggest that there exists any more suitable virus and bacteria
