_New York_, ----.
_My Dear Sir_,--I must be pardoned for refusing your request touching
your MS. "Treatise on Pigs." I was obliged, some years ago, to come to
the resolution not to express opinions of works sent to me. A candid
opinion of those whose merit seemed to me small, gave offence, and I
found it the best way to avoid a judgment in any case. I hope this
will be satisfactory.
