The letter that appeared today was not the same as you indicated in our 
recent correspondence (see below).  By deleting the phrase "Could you 
appreciate the complexity of a symphony by listening only to the percussion 
section of an orchestra?  " the reader is left perplexed by the next 
sentence: "Studies that
have analyzed data from a wider range of instruments than Broecker mentions..."
Unfortunately, the word "instruments" suggests "instrumental records" which 
is NOT what we were talking about.
You also managed to mangle the references so now there is no reference to 
the fifth footnote at all.

This seemingly trivial bit of editing has changed the meaning of my letter 
and it is very annoying to find that you did this after sending me what you 
indicated would be the final edits.  Why bother if you are going to change 
things further?

The other letter that I sent was also changed without anybody asking me 
(fortunately, without altering the meaning, but losing a little humor) and 
I have to say I find this extremely annoying and not very professional.
