The tint is not uniform; long stripes of deeper hue alternating with bands of brighter colour.
الصفحة 82 - The problem of the connection of body and soul is as insoluble in its modern form as it was in the prescientific ages.
الصفحة 133 - There is a certain meddlesome spirit, which, in the garb of learned research, goes prying about the traces of history, casting down its monuments, and marring and mutilating its fairest trophies. Care should be taken to vindicate great names from such pernicious erudition. It defeats one of the most salutary purposes of history, that of furnishing examples of what human genius and laudable enterprise may accomplish.
