Dear Sandro, 
Thanks for your letter. I an very sorry for Tones death 
at such an early age. I heard from Kowalik that he had got 
ill again, This is a cats and mouse game, and I suppose, 
his wife got the worst of it. 
I send you enclosed the abstract. The psfet was not so bad 
this tine, at least not as bad as those letters which you 
sent by dewious routes via Britain, which lasted more than 
three weeks! 
With kind regards, 
lours,
