His faded, light hair was tinged with grey; he had a pinched hook nose; watery blue eyes, and an irresolute-looking mouth; he wore his shabby dress with an affectation of foppish gentility; an eye-glass dangled over his closely buttoned-up waistcoat, and he carried a cane in his ungloved hand.

他枯槁、稀少的头发变成灰白色了；他生着狭长的钩鼻，水汪汪的蓝眼睛，优柔寡断的嘴巴；他穿着破破烂烂的衣服，可还是透出花花公子装腔作势的神气；眼镜摇摇晃晃地挂在密密地扣紧的背心上，不戴手套的手里拿着一根手杖。
