What would Gladstone have accomplished with a weak, puny physique?
He addresses an audience at Corfu in Greek, and another at Florence in Italian.

A little later he converses at ease with Bismarck in German, or talks fluent French in Paris, or piles up argument on argument in English for hours in Parliament.
