BURTON: Would those things last? 



MAGEE: They might last a hundred years. 



BURTON: Okay, there is your picture. The whole thing fits. 



CURTIS: Is it really true that there is no situation in chemistry compara- 

 ble to the phenomenon of photoreactivation? 



PLATZMAN: No. There is, to cite one example, the bleaching of the 

 photographic latent image. This has some features in common with bacterio- 

 phage photoreactivation, but the mechanisms may have nothing whatever in 

 common. 



CURTIS: I am afraid our time is up and we must adjourn. I certainly want 

 to thank you all, on behalf of the National Research Council, for coming and 

 participating in this discussion. I, for one, feel it has been a stimulating meet- 

 ing and hope each of you has profited from it as much as I have.
