Dear Prof. Cohn,

Concerning the measure space you defined [CH: Cohn 16/9 1998]  
I wrote [re: CH,  Riis. 16/9-1998]:

I now realize that you did not define p(A) = 1 for all
uncountable sets, only co-countable ones. Your definition is
however equivalent to my reading of his definition. I give
you my full excuse that I didn't read your definition 
sufficiently careful. My misreading didn't affect my general 
answer though.
