An enumeration array containing a dictionary gives unexpected output

Question

My question is why it displays the last 4 lines in the log (see below) ... are these objects part of the dictionary printed earlier in the log and should not be located at the end of the array? I am missing something fundamental here ... thanks

NSDictionary *dictionary = [NSDictionary dictionaryWithObjectsAndKeys:
    [NSURL URLWithString: @"www.stanford.edu"], 
    @"Stanford University", 
    [NSURL URLWithString: @"www.apple.com"], 
    @"Apple shop", 
    [NSURL URLWithString: @"cs193p.stanford.edu"], 
    @"CS193P course", 
    [NSURL URLWithString: @"itunes.stanford.edu"], 
    @"Stanford on iTunes U", 
    [NSURL URLWithString: @"stanfordshop.com"], 
    @"Stanford Mall", 
    nil];

NSMutableArray *myArray = [NSMutableArray arrayWithObjects:
    [NSString init],
    [NSURL URLWithString: @"www.stanford.edu"],
    [NSProcessInfo processInfo],
    dictionary,
    [@"Mutable string example" mutableCopy],
    [@"another mutable string" mutableCopy]];

NSEnumerator *enumerator = [myArray objectEnumerator];
id object;

while ((object = [enumerator nextObject])) {
    NSLog([object description]);
}
