2 the results of the bioassay would suggest that the eggs 



3 had little chance to survive. I have not been aware of 



4 any unexpected difficulty in rearing naturally spawned 



5 eggs captured in Port Gardner. 



6 My third question was the relationship 



7 between PBI and SWL. I am told that FBI measures sub- 

 g stances other than those which can be compared to the dis- 

 9 charge of SWL from a mill. The conclusions of the Federal 



10 report might be wrong if the PBI measured in Port Gardner 



11 reflects a situation less harmful than similar levels of 



12 SWL in the laboratory bioassays.

Finally, I attempted to learn in a very 



14 crude way whether the results of the laboratory bioassay 



are a useful guide to conditions in the ocean. The ques- 

 tions I have outlined above led me to suspect that natural 

 fish eggs taken from Port Gardner and held in water with 

 high PBI taken from Port Gardner might survive better than 

 the results of the laboratory bioassay seemed to suggest 

 to the authors of the Federal report. We were unable to 

 get water of high PBI and fish eggs at the same time, so 

 we had to use dilutions of sulfite waste liquor obtained 

 from a mill, in the manner of Dr. Berkson. 



The simple experiment used 24 fish eggs. 

 Three eggs were selected at random and placed into each
