Villiers prided himself as a practised explorer of such obscure mazes and byways of London life, and in this unprofitable pursuit he displayed an assiduity which was worthy of more serious employment. Thus he stood by the lamp-post surveying the passers-by with undisguised curiosity, and with that gravity known only to the systematic diner, had just enunciated in his mind the formula: “London has been called the city of encounters; it is more than that, it is the city of Resurrections,” when these reflections were suddenly interrupted by a piteous whine at his elbow, and a deplorable appeal
for alms.
