Newton's obsession with counterfeiters never made sense to me until I read Neal Stephenson Baroque Cycle. He makes a good case for tying it with Newton's prior alemetical pursuits.
Newton was dutiful, honest and smart.
I'd say, "disparaging against the Germans" or "repulsed by confederations" ('Alemanni' ∩ 'emetic').
If somebody is proficient in Arabic, maybe 'emetic' (after article "Al-") makes sense also outside IE...
