Chairman Gerard: Thank you very much Dr. Fischer. I am sure there 

 will be much discussion of your woolly experiments and woolly suggestions. 



Dr. Blum: Have you investigated any other proteins which would be of, 

 say, non-epidermal origin? 



Dr. Fischer: We measured the affinity of compounds to epidermal keratin 

 as well as to proteins of non-epidermal origin, such as egg albumin, casein and 

 insulin; the results are different from and bear no relation to those obtained 

 when using wool protein. 



Dr. Robert Resnick (National Institute of Mental Health): It seemed to 

 me that it might be fortuitous to conduct experiments with one and try to 

 extrapolate to other products when they might be similar in composition. 



Dr. Fischer: As to the similarity in composition of different types of kera-
