UNCONFIRMED  errors and comments from readers: 


[15]  second bullet from the bottom of the page;
"If the object inherits from the receiver's class, the field is not visible."  
I believe the word 'not' is erroneous here. A field that is declared as @protected
can be accessed from this class and any class which inherits from it.



[58]  text of the "NOTE";
This is either confusing or an error. If it refers to the snippet above, it should
say

"Descendents of NSObject will use -dealloc instead of -free."
