SIR,--I greatly regret that my latest publications should have caught
your eye, and look on your congratulations as a studied insult.
I should hardly expect a person of your (as I imagine) limited
intellect to know anything about the scientific subjects which
interest me, but I feel sure that you are perfectly aware that the
calculus is abstract and not concrete.
Had you tried to convey sincere congratulations to me I could have
borne the infliction with resignation, but I strongly object to such
flippant impertinences as are contained in your communication.
Faithfully yours,
FREDERICK PETHERTON.
