 the interfering substances in those locations at the time 

 when the mills were closed, there may have been the 

 indication that they found sulfite waste liquor on the Pearl- 

 Benson Index when the mills were open and not the inter- 

 fering substances. 



PROFESSOR MCCARTHY: Well, our conclusion, 

 of course, in this whole study is that the method is a 

 moderately good reproducible one, but subject to these 



limitations. 



CHAIRMAN STEIN: Right. Thank you very 

 much. 



MR. HARRIS: Thank you. Dr. McCarthy. 



PROFESSOR MCCARTHY: Thank you. 



MR. HARRIS: The next expert on Mr. Benson's 

 panel is Mr. Haydu.
