A World of Wonders, with Anecdotes and Opinions Concerning Popular Superstitions is a manual that examines and explores superstitions. Excerpt: "It is surprising, considering the gigantic strides effected by modern science, how many of the errors and prejudices engendered by the ignorance of the dark ages remain current in the world in its present days of enlightenment. Like the winged seeds of certain weeds, their light and impalpable nature renders them only the more difficult of extirpation."
