John Morrison Davidson, Eminent English liberals in and out of Parliament… (1880)
“ Gladstone is of pure Scottish blood,—a fact of which he has oftener than once expressed himself proud. Indeed, the perfervidum ingenium Scotorum is his in a remarkable degree; and it has its influence on public opinion across the border, notwithstanding his English training and his antipathetic High-Churchism. However England may abase herself before the gorgeous Lord Benjingo, Scotland will never turn her back on the undecorated Gladstone. There lives not a Scotsman that is not inwardly proud of him; for blood is, after all, thicker than water. ”
